PART I

NORFOLK SOUTHERN CORPORATION AND SUBSIDIARIES (NS)

Item 1. Business and Item 2. Properties

GENERAL - Norfolk Southern Corporation (Norfolk Southern) is a Norfolk, Virginia based company that controls a major freight railroad, Norfolk Southern Railway Company. Norfolk Southern Railway Company is primarily engaged in the rail transportation of raw materials, intermediate products, and finished goods primarily in the Southeast, East, and Midwest and, via interchange with rail carriers, to and from the rest of the United States. Norfolk Southern also transports overseas freight through several Atlantic and Gulf Coast ports. Norfolk Southern provides comprehensive logistics services and offers the most extensive intermodal network in the eastern half of the United States. The common stock of Norfolk Southern is listed on the New York Stock Exchange (NYSE) under the symbol “NSC.”

Norfolk Southern was incorporated on July 23, 1980, under the laws of the Commonwealth of Virginia. On June 1, 1982, Norfolk Southern acquired control of two major operating railroads, Norfolk and Western Railway Company (NW) and Southern Railway Company (Southern) in accordance with an Agreement of Merger and Reorganization dated as of July 31, 1980, and with the approval of the transaction by the Interstate Commerce Commission (now the Surface Transportation Board [STB]). Effective December 31, 1990, Norfolk Southern transferred all the common stock of NW to Southern and Southern’s name was changed to Norfolk Southern Railway Company (Norfolk Southern Railway or NSR). Effective September 1, 1998, NW was merged with and into Norfolk Southern Railway. As of December 31, 2010, all the common stock of Norfolk Southern Railway was owned directly by Norfolk Southern.

Norfolk Southern makes available free of charge through its website, www.nscorp.com, its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports as soon as reasonably practicable after such material is electronically filed with or furnished to the Securities and Exchange Commission (SEC). In addition, the following documents are available on the company’s website and in print to any shareholder who requests them:

Total	20,183	4,663	2,382	9,121	36,349

Triple Crown Operations - Triple Crown Services Company (Triple Crown), an NS subsidiary, provides bimodal, truckload transportation service utilizing RoadRailer® trailers, a hybrid technology that facilitates both over-the-road and on-the-rail transportation utilizing enclosed trailers that are pulled over the highways in tractor-trailer configuration and over the rails by locomotives. Triple Crown provides service in the eastern two-thirds of the United States as well as Ontario and Quebec through a network of terminals strategically located in 13 cities.

The following table sets forth certain statistics relating to NS’ railroads’ operations for the past 5 years:

	Years Ended December 31,

	2010	2009	2008	2007	2006
Revenue ton miles (billions)	182	159	195	196	204
Freight train miles traveled (millions)	72.6	67.5	80.0	81.9	84.2
Revenue per ton mile	$0.0523	$0.0503	$0.0546	$0.0481	$0.0462
Revenue ton miles per employee-hour worked	3,218	2,900	3,075	3,066	3,196
Ratio of railway operating expenses to railway operating revenues	71.9%	75.4%	71.1%	72.6%	72.8%

RAILWAY OPERATING REVENUES - NS’ total railway operating revenues were $9.5 billion in 2010. See the financial information by traffic segment in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

COAL TRAFFIC - Coal, coke, and iron ore - most of which is bituminous coal - is NS’ railroads’ largest commodity group as measured by revenues. The railroads handled a total of 170.8 million tons in 2010, most of which originated on NS’ lines in West Virginia, Virginia, Pennsylvania, and Kentucky. Revenues from coal, coke, and iron ore accounted for about 28% of NS’ total railway operating revenues in 2010.

Total coal handled through all system ports in 2010 was 36.6 million tons. Of this total, 16.6 million tons (including coastwise traffic) moved through Norfolk, Virginia, 8.3 million tons moved to various docks on the Ohio River, 7.1 million tons (including coastwise traffic) moved through the Baltimore Terminal, and 4.6 million tons moved to various Lake Erie ports. Other than coal for export, virtually all coal handled by NS’ railroads was terminated in states east of the Mississippi River.

See the discussion of coal traffic, by type of coal, in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

GENERAL MERCHANDISE TRAFFIC - General merchandise traffic is composed of five major commodity groupings: automotive; chemicals; metals and construction; agriculture; consumer products and government; and paper, clay and forest products. The automotive group includes finished vehicles for BMW, Chrysler, Ford Motor Company, General Motors, Honda, Hyundai, Mazda, Mercedes-Benz, Mitsubishi, Subaru, Suzuki, Toyota and Volkswagen, and auto parts for Ford Motor Company, General Motors, and Chrysler. The chemicals group includes sulfur and related chemicals, petroleum products, chlorine and bleaching compounds, plastics, rubber, industrial chemicals, chemical wastes, and municipal wastes. The metals and construction group includes steel, aluminium products, machinery, scrap metals, cement, aggregates, bricks, and minerals. The agriculture, consumer products, and government group includes soybeans, wheat, corn, fertilizer, animal and poultry feed, food oils, flour, beverages, canned goods, sweeteners, consumer products, ethanol, and items for the military. The paper, clay and forest products group includes lumber and wood products, pulp board and paper products, wood fibers, wood pulp, scrap paper, and clay.

In 2010, 123 million tons of general merchandise freight, or approximately 66% of total general merchandise tonnage handled by NS, originated online. The balance of general merchandise traffic was received from connecting carriers at interterritorial gateways. The principal interchange points for NS-received traffic included Chicago, Memphis, New Orleans, Cincinnati, Kansas City, Detroit, Hagerstown, St. Louis/East St. Louis, and Louisville. General merchandise carloads handled in 2010 were 2.3 million, the revenues from which accounted for 53% of NS’ total railway operating revenues in 2010.

See the discussion of general merchandise rail traffic by commodity group in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

INTERMODAL TRAFFIC - The intermodal market consists of shipments moving in trailers, domestic and international containers, and RoadRailer® equipment. These shipments are handled on behalf of intermodal marketing companies, international steamship lines, truckers, and other shippers. Intermodal units handled in 2010 were 2.9 million, the revenues from which accounted for 19% of NS’ total railway operating revenues for the year.

See the discussion of intermodal traffic in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

FREIGHT RATES - In 2010, NS’ railroads continued their reliance on private contracts and exempt price quotes as their predominant pricing mechanisms. Thus, a major portion of NS’ freight business is not currently economically regulated by the government. In general, market forces have been substituted for government regulation and now are the primary determinant of rail service prices.

In 2010, NS’ railroads were found by the STB to not be “revenue adequate” based on results for the year 2009. The STB has not made its revenue adequacy determination for the year 2010. A railroad is “revenue adequate” on an annual basis under the applicable law when its return on net investment exceeds the rail industry’s composite cost of capital. This determination is made pursuant to a statutory requirement.

PASSENGER OPERATIONS

Regularly scheduled passenger trains are operated by Amtrak on NS’ lines between the following locations:
–          Alexandria, Virginia, and New Orleans, Louisiana
–          Raleigh and Charlotte, North Carolina

–          Southeastern Pennsylvania Transportation Authority
–          Metro-North Commuter Railroad Company
–          Maryland Department of Transportation
Passenger operations are conducted either by Amtrak or by the commuter agencies over trackage owned by Conrail in the Shared Assets Areas (see Note 5 to consolidated financial statements)

NONCARRIER OPERATIONS - NS’ noncarrier subsidiaries engage principally in the acquisition, leasing, and management of coal, oil, gas and minerals; the development of commercial real estate; telecommunications; and the leasing or sale of rail property and equipment. In 2010, no such noncarrier subsidiary or industry segment grouping of noncarrier subsidiaries met the requirements for a reportable business segment, under relevant authoritative accounting guidance.

RAILWAY PROPERTY

The NS railroad system extends across 22 states and the District of Columbia. The railroad infrastructure makes the company capital intensive with net property of approximately $23 billion.

Capital Expenditures - Capital expenditures for the past five years were as follows (including capitalized leases):

		Capital Expenditures
		($ in millions)

		2010		2009		2008		2007		2006

	Locomotives	Freight Cars

Average age - in service	20.5 years	31.0 years
Retirements	75 units	2,002 units
Average age - retired	28.4 years	41.9 years

Ongoing locomotive and freight car maintenance programs are intended to ensure the highest standards of safety, reliability, customer satisfaction, and equipment marketability. The locomotive bad order ratio includes all units (owned and leased) out of service for required inspections every 92 days, program work such as overhauls, and unscheduled maintenance.

	Annual Average Bad Order Ratio

	2010	2009	2008	2007	2006
Locomotives	6.7%	6.1%	5.8%	5.7%	5.7%
Freight cars	5.8%	4.5%	4.5%	4.9%	6.4%

Encumbrances - Certain railroad equipment is subject to the prior lien of equipment financing obligations amounting to approximately $112 million as of December 31, 2010, and $150 million as of December 31, 2009.

Track Maintenance - Of the approximately 36,300 total miles of track operated, NS had the responsibility for maintaining about 29,400 miles of track, with the remainder being operated under trackage rights from another party responsible for maintenance.

Over 80% of the main line trackage (including first, second, third, and branch main tracks, all excluding rail operated pursuant to trackage rights) has rail ranging from 131 to 155 pounds per yard with the standard installation currently at 136 pounds per yard. Approximately 43% of NS lines, excluding rail operated pursuant to trackage rights, carried 20 million or more gross tons per track mile during 2010.

The following table summarizes several measurements regarding NS’ track roadway additions and replacements during the past five years:

	2010	2009	2008	2007	2006

Track miles of rail installed	422	434	459	401	327
Miles of track surfaced	5,326	5,568	5,209	5,014	4,871
New crossties installed (millions)	2.6	2.7	2.7	2.7	2.7

Microwave System - The NS microwave system, consisting of approximately 7,400 radio route miles, 425 core stations, 30 secondary stations, and 5 passive repeater stations, provides communications between most operating locations. The microwave system is used primarily for voice communications, VHF radio control circuits, data and facsimile transmissions, traffic control operations, and AEI data transmissions.

Traffic Control - Of the approximately 16,500 route miles dispatched by NS, about 11,000 miles are signalized, including 8,100 miles of centralized traffic control (CTC) and 2,900 miles of automatic block signals. Of the 8,100 miles of CTC, approximately 4,050 miles are controlled by data radio originating at 284 base station radio sites.

Computers - A computer network consisting of a centralized data center in Atlanta, Georgia, and various distributed computers throughout the company connects the yards, terminals, transportation offices, rolling stock repair points, sales offices, and other key system locations. Operating and traffic data are processed and stored to provide customers with information on their shipments throughout the system. Computer systems provide current information on the location of every train and each car on line, as well as related waybill and other train and car movement data. In addition, the computer systems are utilized to assist management in the performance of a variety of functions and services including payroll, car and revenue accounting, billing, material management activities and controls, and special studies.

ENVIRONMENTAL MATTERS - Compliance with federal, state, and local laws and regulations relating to the protection of the environment is a principal NS goal. To date, such compliance has not affected materially NS’ capital additions, earnings, liquidity, or competitive position. See “Legal Proceedings,” Part I, Item 3; “Personal Injury, Environmental, and Legal Liabilities” in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Note 17 to the Consolidated Financial Statements.

EMPLOYEES - The following table shows the average number of employees and the average cost per employee for wages and benefits:

	2010	2009	2008	2007	2006

Average number of employees	28,559	28,593	30,709	30,806	30,541

Average wage cost per employee	$69,000	$63,000	$66,000	$62,000	$62,000

Average benefit cost per employee	$37,000	$32,000	$31,000	$30,000	$32,000

More than 80% of NS’ railroad employees are covered by collective bargaining agreements with various labor unions. See the discussion of “Labor Agreements” in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

GOVERNMENT REGULATION - In addition to environmental, safety, securities, and other regulations generally applicable to all business, NS’ railroads are subject to regulation by the STB. The STB has jurisdiction over some rates, routes, fuel surcharges, conditions of service, and the extension or abandonment of rail lines. The STB also has jurisdiction over the consolidation, merger, or acquisition of control of and by rail common carriers. The Federal Railroad Administration regulates certain track and mechanical equipment standards.

K10

The relaxation of economic regulation of railroads, under the Staggers Rail Act of 1980, includes exemptions of intermodal business (trailer-on-flat-car, container-on-flat-car), rail boxcar traffic, lumber, manufactured steel, automobiles, and certain bulk commodities such as sand, gravel, pulpwood, and wood chips for paper manufacturing. Transportation contracts on these shipments and on regulated shipments effectively remove those shipments from regulation as well for the duration of the contract. About 87% of NS’ freight revenues come from either exempt traffic or traffic moving under transportation contracts.

Efforts were made in 2010 to re-subject the rail industry to increased federal economic regulation and such efforts are expected to continue in 2011. The Staggers Rail Act of 1980, which substantially balanced such regulation, encouraged and enabled rail carriers to innovate and to compete for business, thereby contributing to the economic health of the nation and to the revitalization of the industry. Accordingly, NS will continue to oppose efforts to reimpose increased economic regulation.

COMPETITION - There is continuing strong competition among rail, water, and highway carriers. Price is usually only one factor of importance as shippers and receivers choose a transport mode and specific hauling company. Inventory carrying costs, service reliability, ease of handling, and the desire to avoid loss and damage during transit are also important considerations, especially for higher-valued finished goods, machinery, and consumer products. Even for raw materials, semifinished goods, and work-in progress, users are increasingly sensitive to transport arrangements that minimize problems at successive production stages.

NS’ primary rail competitor is the CSX system; both operate throughout much of the same territory. Other railroads also operate in parts of the territory. NS also competes with motor carriers, water carriers, and with shippers who have the additional option of handling their own goods in private carriage, of sourcing products from different geographic areas, and of using substitute products.

Certain marketing strategies among railroads and between railroads and motor carriers enable carriers to compete more effectively in specific markets.

SECURITY OF OPERATIONS - NS has taken significant steps to provide enhanced security for the NS rail system. In particular, NS has developed and implemented a comprehensive security plan that is modeled on and was developed in conjunction with the security plan prepared by the Association of American Railroads (AAR) post September 11, 2001. The AAR Security Plan defines four Alert Levels and details the actions and countermeasures that are being applied across the railroad industry as the terrorist threat increases or decreases. The Alert Level actions include countermeasures that will be applied in three general areas: (1) operations (including transportation, engineering, and mechanical); (2) information technology and communications; and (3) railroad police. Although security concerns preclude public disclosure of its contents, the NS Departmental Security Plan outlines the protocol within NS for all concerned to be no tified of AAR Alert Level changes. All NS Operations Division employees are advised by their supervisors or train dispatchers, as appropriate, of any change in Alert Level and any additional responsibilities they may incur due to such change.

The NS plan also effectively addresses and complies with Department of Transportation security regulations pertaining to training and security plans with respect to the transportation of hazardous materials. As part of the plan, security awareness training is given to all railroad employees who directly affect hazardous material transportation safety, and this training is integrated into recurring hazardous material training and re-certification programs. Toward that end, NS, working closely with the National Transit Institute at Rutgers University, has developed a four-module uniform national training program. NS also has worked with the Transportation Security Administration (TSA) in developing other industry training programs. More in-depth security training has been given to those select NS employees who have been given specific security responsibilities, and additional, location-specific security plans have been developed for certain metropolit an areas and each of six port facilities served by NS. With respect to the ports, each facility plan has been approved by the applicable Captain of the Port and subject to inspection by the U.S. Coast Guard.

K11

Additionally, NS engages in close and regular coordination with numerous federal and state agencies, including the U.S. Department of Homeland Security (DHS), the TSA, the Federal Bureau of Investigation (FBI), the Federal Railroad Administration (FRA), the U.S. Coast Guard, U.S. Customs and Border Protection, and various state Homeland Security offices. As one notable example, an NS Police Special Agent, under the auspices of the AAR, has been assigned to the National Joint Terrorism Task Force (NJTTF) operating out of FBI Headquarters in Washington, DC to represent and serve as liaison to the North American rail industry. This arrangement improves logistical flow of vital security and law enforcement information with respect to the rail industry as a whole, while having the post filled by an NS Special Agent has served to foster a strong working relationship between NS and the FBI. NS also has become a member of the Customs-Trade Partnership Against Terroris m (C-TPAT) program sponsored by U.S. Customs. C-TPAT allows NS to work closely with U.S. Customs and its customers to develop measures that will help ensure the integrity of freight shipments moving on NS, particularly those moving to or from a foreign country. Based on participation in C-TPAT, NS has ensured that its plan meets all current applicable security recommendations made by U.S. Customs.

Similarly, NS is guided in its operations by various supplemental security action items issued by DHS and U.S. Department of Transportation (DOT), U.S. Coast Guard Maritime Security requirements, as well as voluntary security action items developed in 2006 in collaboration with TSA, DOT, and the freight railroads. Many of the action items are based on lessons learned from DHS and DOT security assessments of rail corridors in High Threat Urban Areas (HTUA) begun in 2004. Particular attention is aimed at reducing risk in HTUA by: (1) the establishment of secure storage areas for rail cars carrying toxic-by-inhalation (TIH) materials; (2) the expedited movement of trains transporting rail cars carrying TIH materials; (3) the minimization of unattended loaded tank cars carrying TIH materials; and (4) cooperation with federal, state, local and tribal governments to identify, through risk assessments, those locations where security risks are the highest. These action items and NS’ compliance initiatives are outlined in the various departmental sections of the NS Departmental Security Plan. NS has taken appropriate actions to be compliant with the 2008 TSA Final Security Rule addressing Rail Security Sensitive Materials (RSSM) to ensure these shipments are properly inspected and that positive chain-of-custody is maintained when required. NS has met the September 2009 deadline to be in compliance with the 2008 Pipeline and Hazardous Materials Safety Administration (PHMSA) rail-routing regulations outlined in Docket HM-232E. In 2010, this methodology and selected routes were reviewed by PHMSA, and found to be compliant with the regulation.

In 2010, through participation in the Transportation Community Awareness and Emergency Response (TRANSCAER) Program, NS provided rail accident response training to approximately 4,890 emergency responders, such as local police and fire personnel, representing over 19,400 man-hours of emergency response training. NS also conducted railroad operations classes for FBI agents and the railroad liaison agents from Joint Terrorism Task Forces. NS’ other training efforts throughout 2010 included participation in 12 drills for local, state, and federal agencies. NS also has ongoing programs to sponsor local emergency responders at the Security and Emergency Response Training Course (SERTC) conducted at the AAR Transportation Technology Center in Pueblo, Colorado.

Improvements in equipment design also are expected to play a role in enhancing rail security. PHMSA, in coordination with the FRA, is amending the Hazardous Materials Regulations to prescribe enhanced safety measures for rail transportation of TIH materials, including interim design standards for railroad tank cars. The rule mandates commodity-specific improvements in safety features and design standards for newly manufactured DOT specification tank cars and an improved top fittings performance standard. The interim standards established in this rule will enhance the accident survivability of TIH tank cars.

Item 1A. Risk Factors

NS is subject to significant governmental legislation and regulation over commercial, operating and environmental matters. Railroads are subject to the enactment of laws by Congress that could increase economic regulation of the industry. Railroads presently are subject to commercial regulation by the STB, which has jurisdiction over some routes, rates and fuel surcharges, conditions of service, and the extension or abandonment of rail lines. The STB also has jurisdiction over consolidations, mergers, or acquisitions involving rail common carriers. Additional economic regulation of the rail industry by Congress or the STB, whether under new or existing laws, could have a significant negative impact on NS’ ability to determine prices for rail services and result in a material adverse effect in the future on NS’ financial position, results of operations, or liquidity in a particular year or quarter. This potenti al material adverse effect could also result in reduced capital spending on NS’ rail network or abandonment of lines.

Railroads are subject to safety and security regulation by the DOT and the DHS, which regulate most aspects of NS’ operations. Compliance with the Rail Safety Improvement Act of 2008 will result in additional operating costs associated with the statutorily mandated implementation of positive train control by 2015. In addition to increased capital expenditures, implementation may result in reduced operational efficiency and service levels, as well as increased compensation and benefits expenses, and increased claims and litigation costs.

NS’ operations are subject to extensive federal and state environmental laws and regulations concerning, among other things, emissions to the air; discharges to waterways or ground water supplies; handling, storage, transportation, and disposal of waste and other materials; and the cleanup of hazardous material or petroleum releases. The risk of incurring environmental liability - for acts and omissions, past, present, and future - is inherent in the railroad business. This risk includes property owned by NS, whether currently or in the past, that is or has been subject to a variety of uses, including NS railroad operations and other industrial activity by past owners or past and present tenants of NS. Environmental problems that are latent or undisclosed may exist on these properties, and NS could incur environmental liabilities or costs, the amount and materiality of which cannot be estimated reliably at this time, with respect to one or more of these properties. Moreover, lawsuits and claims involving other unidentified environmental sites and matters are likely to arise from time to time, and the resulting liabilities could have a significant effect on financial position, results of operations, or liquidity in a particular year or quarter.

NS, as a common carrier by rail, must offer to transport hazardous materials, regardless of risk. Transportation of certain hazardous materials could create catastrophic losses in terms of personal injury and property damage costs, and compromise critical parts of our rail network.

NS may be affected by terrorism or war. Any terrorist attack, or other similar event, any government response thereto, and war or risk of war could cause significant business interruption and may adversely affect NS’ results of operations, financial position, or liquidity in a particular year or quarter. Because NS plays a critical role in the nation’s transportation system, it could become the target of such an attack or have a significant role in the government’s preemptive approach or response to an attack or war.

Although NS currently maintains insurance coverage for third-party liability arising out of war and acts of terrorism, it maintains only limited insurance coverage for first-party property damage and damage to property in NS’ care, custody, or control caused by certain acts of terrorism. In addition, premiums for some or all of NS’ current insurance programs covering these losses could increase dramatically, or insurance coverage for certain losses could be unavailable to NS in the future.

NS may be affected by general economic conditions. Prolonged negative changes in domestic and global economic conditions affecting the producers and consumers of the commodities NS carries may have an adverse effect on its operating results, financial position, or liquidity. Economic conditions resulting in bankruptcies of one or more large customers could have a significant impact on NS’ financial position, results of operations, or liquidity in a particular year or quarter.

K13

NS may be affected by climate change legislation or regulation. Concern over climate change has led to significant federal, state, and international legislative and regulatory efforts to limit greenhouse gas (“GHG”) emissions. Moreover, even without such legislation or regulation, government incentives and adverse publicity relating to GHG’s could affect certain of our customers and the markets for certain of the commodities we carry. Restrictions, caps, taxes, or other controls on GHG emissions, including diesel exhaust, could significantly increase NS’ operating costs, decrease the amount of traffic handled, and decrease the value of coal reserves owned by NS, and thus could have an adverse effect on NS’ operating results, financial position and liquidity. Such restrictions could affect NS’ customers that (1) use commodities that NS carries to produce energy, including coal, (2) use significant amounts of energy in producing or delivering the commodities NS carries, or (3) manufacture or produce goods that consume significant amounts of energy.

NS faces competition from other transportation providers. NS is subject to competition from motor carriers, railroads, and to a lesser extent, ships, barges, and pipelines, on the basis of transit time, pricing, and the quality and reliability of service. While NS has used primarily internal resources to build or acquire and maintain its rail system, trucks and barges have been able to use public rights-of-way maintained by public entities. Any future improvements or expenditures materially increasing the quality or reducing the cost of alternative modes of transportation in the regions in which NS operates, or legislation granting materially greater latitude for motor carriers with respect to size or weight limitations, could have a material adverse effect on its financial position, results of operations, or liquidity in a particular year or quarter.

The operations of carriers with which NS interchanges may adversely affect its operations. NS’ ability to provide rail service to customers in the U.S. and Canada depends in large part upon its ability to maintain cooperative relationships with connecting carriers with respect to, among other matters, freight rates, revenue division, car supply and locomotive availability, data exchange and communications, reciprocal switching, interchange, and trackage rights. Deterioration in the operations of, or service provided by connecting carriers, or in our relationship with those connecting carriers, could result in NS’ inability to meet its customers’ demands or require NS to use alternate train routes, which could result in significant additional costs and network inefficiencies.

NS relies on technology and technology improvements in its business operations. If NS experiences significant disruption or failure of one or more of its information technology systems, including computer hardware, software, and communications equipment, NS could experience a service interruption, security breach, or other operational difficulties, which could have a material adverse impact on its results of operations, financial condition, and liquidity in a particular year or quarter. Additionally, if NS does not have sufficient capital to acquire new technology or it is is unable to implement new technology, NS may suffer a competitive disadvantage within the rail industry and with companies providing other modes of transportation service, which could have a material adverse effect on its financial position, results of operations, or liquidity in a particular year or quarter.

The vast majority of NS employees belong to labor unions, and labor agreements, strikes, or work stoppages could adversely affect its operations. More than 80% of NS railroad employees are covered by collective bargaining agreements with various labor unions. If unionized workers were to engage in a strike, work stoppage, or other slowdown, NS could experience a significant disruption of its operations. Additionally, future national labor agreements, or renegotiation of labor agreements or provisions of labor agreements, could significantly increase NS’ costs for healthcare, wages, and other benefits. Any of these factors could have a material adverse impact on NS’ financial position, results of operations, or liquidity in a particular year or quarter.

NS may be subject to various claims and lawsuits that could result in significant expenditures. The nature of NS’ business exposes it to the potential for various claims and litigation related to labor and employment, personal injury, commercial disputes, freight loss and other property damage, and other matters. Job-related personal injury and occupational claims are subject to the Federal Employer’s Liability Act (FELA), which is applicable only to railroads. FELA’s fault-based tort system produces results that are unpredictable and inconsistent as compared with a no-fault worker’s compensation system. The variability inherent in this system could result in actual costs being very different from the liability recorded.

K14

Any material changes to current litigation trends or a catastrophic rail accident involving any or all of freight loss or property damage, personal injury, and environmental liability could have a material adverse effect on NS’ operating results, financial condition, and liquidity to the extent not covered by insurance. NS has obtained insurance for potential losses for third-party liability and first-party property damages. Specified levels of risk are retained on self-insurance bases (currently up to $50 million and above $1 billion per occurrence for bodily injury and property damage to third parties and up to $25 million and above $175 million per occurrence for property owned by NS or in its care, custody, or control). Insurance is available from a limited number of insurers and may not continue to be available or, if available, may not be obtainable on terms acceptable to NS.

Severe weather could result in significant business interruptions and expenditures. Severe weather conditions and other natural phenomena, including hurricanes, floods, fires, and earthquakes, may cause significant business interruptions and result in increased costs, increased liabilities, and decreased revenues, which could have an adverse effect on NS’ financial position, results of operations, or liquidity in a particular year or quarter.

Unpredictability of demand for rail services resulting in the unavailability of qualified personnel could adversely affect NS’ operational efficiency and ability to meet demand. Workforce demographics, training requirements, and the availability of qualified personnel, particularly engineers and trainmen, could each have a negative impact on NS’ ability to meet demand for rail service. Unpredictable increases in demand for rail services may exacerbate such risks, which could have a negative impact on NS’ operational efficiency and otherwise have a material adverse effect on its financial position, results of operations, or liquidity in a particular year or quarter.

NS may be affected by supply constraints resulting from disruptions in the fuel markets or the nature of some of its supplier markets. NS consumed about 440 million gallons of diesel fuel in 2010. Fuel availability could be affected by any limitation in the fuel supply or by any imposition of mandatory allocation or rationing regulations. If a severe fuel supply shortage arose from production curtailments, increased demand in existing or emerging foreign markets, disruption of oil imports, disruption of domestic refinery production, damage to refinery or pipeline infrastructure, political unrest, war or other factors, NS’ financial position, results of operations, or liquidity in a particular year or quarter could be materially adversely affected. Also, such an event would impact NS as well as its customers and other transportation companies.

Due to the capital intensive nature and industry-specific requirements of the rail industry, there are high barriers of entry for potential new suppliers of core railroad items, such as locomotives and rolling stock equipment. Additionally, NS competes with other industries for available capacity and raw materials used in the production of certain track materials, such as rail and ties. Changes in the competitive landscapes of these limited-supplier markets could result in increased prices or material shortages of materials that could have a material affect on NS’ financial position, results of operations, or liquidity in a particular year or quarter.

The state of capital markets could adversely affect NS’ liquidity. NS from time-to-time relies on the capital markets to provide some of its capital requirements, including the issuance of long-term debt instruments and commercial paper, as well as the sale of certain receivables. Significant instability or disruptions of the capital markets, including the credit markets, or deterioration of NS’ financial condition due to internal or external factors could restrict or eliminate NS’ access to, and/or significantly increase the cost of, various financing sources, including bank credit facilities and issuance of corporate bonds. Instability or disruptions of the capital markets and deterioration of NS’ financial condition, alone or in combination, could also result in a reduction in NS’ credit rating to below investment grade, which could prohibit or restrict NS from accessing external sources of short- and long-term debt financing and/or significantly increase the associated costs.

Item 3. Legal Proceedings

On June 25, 2010, the Ohio Attorney General filed a complaint in the Ashtabula Court of Common Pleas alleging certain violations of water laws by NS’ coal dock in Ashtabula, Ohio and seeking injunctive relief and civil penalties. The complaint was filed simultaneously with a Consent Order for Preliminary Injunction that governs the installation of additional pollution control equipment at the dock. This matter relates to previously disclosed enforcement activity initiated by the Ohio Environmental Protection Agency in early 2008. The Pennsylvania Department of Environmental Protection has submitted to NS a proposed Consent Assessment of Civil Penalty with respect to several alleged environmental releases from September 2007 to January 2009. Although NS will contest liability and the imposition of any penalties, because these governmental proceedings with respect to environmental laws and regulations involve potential fines, penalties or other monetary sanctions in excess of $100,000, we described them here consistent with SEC rules and requirements. NS does not believe that the outcome of these proceedings will have a material effect on its financial position, results of operations, or liquidity.

On November 6, 2007, various antitrust class actions filed against NS and other Class 1 railroads in various Federal district courts regarding fuel surcharges were consolidated in the District of Columbia by the Judicial Panel on Multidistrict Litigation. NS believes the allegations in the complaints are without merit and intends to vigorously defend the cases. NS does not believe that the outcome of these proceedings will have a material effect on its financial position, results of operations, or liquidity. A lawsuit containing similar allegations against NS and four other major railroads that was filed on March 25, 2008, in the U.S. District Court for the District of Minnesota was voluntarily dismissed by the plaintiff subject to a tolling agreement entered into in August 2008.

On March 3, 2010, NS received a Shareholder Litigation Demand Letter alleging that NS officers and directors breached fiduciary duties by causing NS to engage in anti-competitive practices relating to the use of fuel surcharges, which have harmed or will ultimately harm NS. The allegations in the letter relate to those contained in the ongoing fuel surcharge class action litigation. In response to the letter, pursuant to Virginia law, the Board of Directors created a Special Litigation Committee to review and evaluate the facts and circumstances surrounding the claims made in the Demand Letter. On September 28, 2010, the shareholder filed a shareholder derivative complaint in United States District Court in the District of Columbia against NS, each of the current members of the Board of Directors, and former Chairman, President, and Chief Executive Officer. Following an investigation utilizing independent counsel, the Special Litigation Committee is sued a report on November 22, 2010 concluding unanimously that the Company should take no action in response to the Demand and should move to dismiss the Derivative Action because it is not in the best interest of the Company. NS does not believe that the outcome of these proceedings will have a material effect on its financial position, results of operations, or liquidity.

On August 30, 2010, the Pipeline Hazardous Material Safety Administration (“PHMSA”) sent NS a Notice of Probable Violation (“NPV”) and assessment of possible penalty related to a 2009 audit PHMSA conducted at a 5.5-mile locomotive fuel pipeline serving the railroad’s Brosnan Yard in Macon, Georgia. In addition, on December 13, 2010, NS made voluntary disclosures to PHMSA regarding potential violations relative to a 5.5-mile pipeline in Goldsboro, North Carolina, that is owned by a wholly owned subsidiary and that supplies jet fuel to the United States Air Force. It is likely that these matters will involve potential fines, penalties, or other monetary sanctions in excess of $100,000 and are therefore described here consistent with SEC rules and requirements. NS does not believe resolution of these claims will have a material effect on its financial position, results of operations, or liquidity.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Norfolk Southern Corporation and Subsidiaries
Management’s Discussion and Analysis of
Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the Consolidated Financial Statements and Notes and the Selected Financial Data.

OVERVIEW

NS’ results in 2010 reflect a substantial increase in revenues due to increased traffic volumes and higher average revenue per unit, driven by the growth of domestic and global economies. Revenues increased $1.5 billion, or 19%, in 2010, as higher demand for rail freight transportation led to additional volumes. Carloadings were up 806,800 units, or 14%, reflecting growth in all commodity groups. Operating expenses increased $833 million, reflecting increased traffic volumes as well as higher fuel prices. Despite the 14% increase in expenses, the operating ratio, a measure of the amount of operating revenues consumed by operating expenses, improved to 71.9%, and income from railway operations rose 36%.

Cash provided by operating activities was $2.7 billion, which allowed for capital expenditures and share repurchases. During 2010, 14.7 million shares of Norfolk Southern Corporation common stock (Common Stock) were repurchased at a total cost of $863 million. Since inception of the stock repurchase program in 2006, NS has repurchased and retired 79.4 million shares of Common Stock at a total cost of $4.1 billion. At December 31, 2010, cash, cash equivalents, and short-term investments totaled $1.1 billion.

Looking forward to 2011, NS expects revenues to increase, reflecting higher traffic volumes but at a more modest pace than seen in 2010, and improved average revenue per unit. NS plans to continue to focus on safety, improve service levels and maintain a market-based approach to pricing.

SUMMARIZED RESULTS OF OPERATIONS

2010 Compared with 2009

Net income in 2010 was $1.5 billion, or $4.00 per diluted share, up $462 million, or 45%, compared with $1.0 billion, or $2.76 per diluted share, in 2009. The increase in net income was primarily due to higher income from railway operations that was offset in part by higher income taxes (see Note 3). Railway operating revenues increased $1.5 billion, reflecting higher traffic volumes and higher average revenue per unit, including fuel surcharges. Railway operating expenses increased $833 million, principally due to higher volume-related expenses and fuel prices.

Oil prices affect NS’ results of operations in a variety of ways and can have an overall favorable or unfavorable impact in any particular period. In addition to the impact of oil prices on general economic conditions and traffic volume, oil prices directly affect NS’ revenues through market-based fuel surcharges and contract escalators (see “Railway Operating Revenues”) and also affect fuel costs (see “Railway Operating Expenses”). For 2010, excluding the impact of increased consumption, the increase in fuel surcharge revenue was greater than the increase in fuel expense. Future changes in oil prices may cause volatility in operating results that could be material to a particular year or quarter.

K20

2009 Compared with 2008

Net income in 2009 was $1.0 billion, or $2.76 per diluted share, down $682 million, or 40%, compared with $1.7 billion, or $4.52 per diluted share, in 2008. The decrease in net income was primarily due to lower income from railway operations that was offset in part by lower income taxes (see Note 3). Railway operating revenues decreased $2.7 billion, reflecting lower traffic volumes and lower average revenue per unit primarily a result of decreased fuel surcharges. Railway operating expenses decreased $1.6 billion, primarily due to lower volume-related expenses and fuel prices.

DETAILED RESULTS OF OPERATIONS

Railway Operating Revenues

Railway operating revenues were $9.5 billion in 2010, $8.0 billion in 2009, and $10.7 billion in 2008. The following table presents a three-year comparison of revenues, volumes, and average revenue per unit by market group.

Revenues increased $1.5 billion in 2010, but decreased $2.7 billion in 2009. As reflected in the table on the following page, the increase in 2010 was due to increased traffic volumes and higher average revenue per unit, which was driven by higher fuel surcharges and rate increases, offset in part by the effects of changes in the mix of traffic. The decrease in 2009 was due to decreased traffic volumes and lower average revenue per unit, as a result of lower fuel surcharges, that more than offset rate increases. Fuel surcharge revenue amounted to $724 million in 2010, compared with $370 million in 2009, and $1.6 billion in 2008. If fuel prices remain at or near year-end 2010 levels, fuel surcharge revenues will increase in 2011.

Many of NS’ negotiated fuel surcharges for coal and general merchandise traffic are based on the monthly average price of West Texas Intermediate Crude Oil (WTI Average Price). These surcharges are reset the first day of each calendar month based on the WTI Average Price for the second preceding calendar month. This two-month lag in applying WTI Average Price decreased fuel surcharge revenue by approximately $28 million in 2010 and $50 million in 2009, but increased fuel surcharge revenue by approximately $100 million in 2008.

Revenue Variance Analysis
Increases (Decreases)

		2010 vs. 2009		2009 vs. 2008
		($ in millions)

Traffic volume (units)	$	1,079	$	(2,020)
Revenue per unit		468		(672)
Total	$	1,547	$	(2,692)

For 2010, the favorable volume variance accounted for 70% of the total increase, reflecting traffic volume improvements in all commodity groups. Volumes increased by 806,800 units, or 14%, reflecting the strengthening of the economy. The favorable revenue per unit variance reflected increased fuel surcharges and higher rates, offset in part by the effects of changes in the mix of traffic.

In 2009, the unfavorable volume variance accounted for 75% of the total decrease, reflecting traffic volume declines for all commodity groups. Volumes declined by 1.4 million units, or 19%, reflecting the weakened economy. The unfavorable revenue per unit variance was driven by decreased fuel surcharges, offset in part by higher rates.

Two of NS’ customers, DuPont and South Mississippi Electric Power Association (SMEPA), have filed rate reasonableness complaints at the Surface Transportation Board (STB) alleging that the NS tariff rates for transportation of regulated movements are unreasonable. NS is disputing these allegations. Since June 1, 2009, in the case of DuPont, and since January 1, 2011, in the case of SMEPA, NS has been billing and collecting amounts from the customers based on the challenged tariff rates. Management presently expects resolution of these cases to occur in late 2012 or 2013. Although the cases have not progressed to a point where management can evaluate the likelihood of the outcome, unfavorable rulings could have a materially adverse effect on NS’ financial position, results of operations, or liquidity.

COAL revenues increased $455 million, or 20%, compared with 2009, reflecting higher average revenue per unit and a 10% increase in traffic principally due to a rise in domestic and global steel production. Coal average revenue per unit was up 9%, compared with 2009, reflecting increased fuel surcharge revenue and improved pricing.

For 2011, coal revenues are expected to increase due to higher volumes and increased average revenue per unit driven by pricing improvement, higher fuel surcharges, and contract escalators.

Coal represented 28% of NS’ revenues in 2010 and 80% of shipments handled originated on NS’ lines. As shown in the following table, tonnage increased in all coal markets.

Total Coal, Coke, and Iron Ore Tonnage

	2010	2009	2008
	(tons in thousands)

Utility	120,737	120,278	144,451
Export	22,750	17,885	23,069
Domestic metallurgical	19,771	11,848	18,155
Industrial	7,573	7,509	8,553
Total	170,831	157,520	194,228

In 2009, coal revenues decreased $847 million, or 27%, compared with 2008, reflecting a 20% decrease in traffic volume due to lower coal consumption in the utility and global raw steel sectors and lower average revenue per unit. Coal average revenue per unit was down 9% compared with 2008, reflecting decreased fuel surcharges and declining rate adjustment factors that more than offset rate increases.

K22

Utility coal tonnage improved slightly as residential demand increased due to severe winter weather and above average summer temperatures on the east coast. Additionally, electricity demand in the industrial sector was higher. These increases more than offset the effects of low natural gas prices and the divergence of utility coal to the export market.

In 2009, utility coal tonnage decreased 17% compared with 2008, a result of lower demand for electricity induced by the downturn in the U.S. economy, natural gas competition, and utility coal stockpiles that were above target levels across NS’ service area.

For 2011, utility coal tonnage is anticipated to increase as new mines come on line and a previously idled plant resumes operations. However, utility coal will have to compete with continued low natural gas prices.

Export coal tonnage increased 27% compared to 2009, reflecting increased global demand for coal used in steel production. Tonnage handled through Norfolk was up about 1.3 million tons, or 9%, and Baltimore tonnage handled increased about 3.5 million tons, or 97%.

In 2009, export coal tonnage decreased 22% compared to 2008, reflecting the global recession, reduced demand for steel production and high inventory levels. Norfolk tonnage handled decreased about 3.1 million tons, or 18%, and Baltimore tonnage was down about 2.1 million tons, or 37%.

For 2011, export coal tonnage is expected to increase in response to the impact of Australian flooding on global coal supply and the expected continuation of strong global demand for steel.

Domestic metallurgical coal, coke, and iron ore tonnage increased 67% compared with 2009, as domestic steel production improved due to an increase in steel demand as blast furnaces resumed operations.

In 2009, domestic metallurgical coal, coke, and iron ore tonnage decreased 35% compared with 2008, reflecting reduced demand for raw steel caused by the downturn in the U.S. economy which led to blast furnace outages, reduced coke production schedules, and high inventory levels.

For 2011, domestic metallurgical coal, coke, and iron ore tonnage is expected to be flat compared to 2010.

Other coal tonnage (principally steam coal shipped to industrial plants) increased 1% compared to 2009, primarily due to new business and increased demand in the steel market.

In 2009, other coal tonnage decreased 12% compared to 2008, primarily due to reduced production at NS-served plants caused by the downturn in the U.S. economy.

For 2011, other coal tonnage is expected to be flat compared to 2010.

GENERAL MERCHANDISE revenues in 2010 increased $826 million, or 20%, compared with 2009, reflecting a 14% increase in traffic volume and a 5% improvement in average revenue per unit, reflecting increased fuel surcharge revenue and higher rates.

K23

In 2009, general merchandise revenues decreased $1.3 billion, or 24%, compared with 2008, reflecting a 21% decline in traffic volume and a 3% decrease in average revenue per unit, as higher rates were overshadowed by decreased fuel surcharge revenues.

Agriculture, consumer products, and government revenues increased 12%, compared with 2009, due to an 11% increase in traffic volume and a 1% increase in average revenue per unit. The increase in traffic volume was a result of more shipments of sweeteners and corn due to continued strength in the demand for ethanol; higher fertilizer volumes due to farmers replenishing nutrients to meet increased crop demand; and, increased feed volumes due to a strong export market.

In 2009, agriculture, consumer products, and government revenues decreased 8%, compared with 2008. The revenue decline resulted from an 8% decrease in traffic volumes as plant closures and production curtailments led to fewer shipments of fertilizer and corn.

For 2011, agriculture revenues are expected to improve as a result of increased volumes and higher average revenue per unit, reflecting expected growth in sweeteners and corn driven by gains in the ethanol market.

Chemicals revenue in 2010 increased 23%, compared with 2009, due to an 18% increase in traffic volume and a 5% growth in average revenue per unit, reflecting higher rates and increased fuel surcharges. Volume gains reflected new business of fly ash in addition to higher shipments of petroleum, industrial intermediates, plastics, and miscellaneous chemicals resulting from improvements in the economy.

In 2009, chemicals revenues decreased 15%, compared with 2008, due to a 12% decrease in traffic volume and a 3% decline in average revenue per unit, primarily a result of lower fuel surcharges. The decline in traffic volume was a result of continued weakness in housing construction which drove declines in industrial intermediates, plastics and miscellaneous chemicals. Volumes associated with pretroleum-based products also declined as a result of reduced demand for asphalt and production curtailments.

For 2011, chemicals revenues are anticipated to increase as higher average revenue per unit coupled with increased shipments of petroleum products, plastics, and industrial intermediates, which partially offset lower volumes of fly ash.

Metals and construction revenues increased 36% in 2010, reflecting a 25% increase in traffic volume and a 9% increase in average revenue per unit, driven by pricing gains and increased fuel surcharges. The increase in traffic volume was principally due to more shipments of coil, iron and steel, and scrap metal due to increased steel and automotive production, as well as higher shipments of fractionating sand for natural gas drilling.

In 2009, metals and construction revenues decreased 40%, reflecting a 32% decrease in traffic volume and a 12% decline in average revenue per unit, primarily a result of lower fuel surcharges. The decline in traffic volume was principally due to lower coil, scrap metal, iron and steel shipments, in addition to reduced demand for construction materials as a result of continued weakness in the housing, infrastructure, and automotive sectors.

For 2011, metals and construction revenues are expected to increase as a result of higher metal-related traffic volumes due to increased domestic and global steel production, in addition to growth in the natural gas drilling sector. Additionally, average revenue per unit is expected to be higher.

Paper, clay and forest products revenues increased 7% in 2010, compared with 2009. The improvement resulted from a 7% increase in traffic volumes, reflecting increased pulp board, pulp, kaolin, lumber, and newsprint shipments as a result of improvements in the domestic and global economics.

In 2009, paper, clay, and forest products revenues decreased 26%, compared with 2008, due to a 22% decrease in traffic volumes and a 5% decline in average revenue per unit, primarily a result of lower fuel surcharges. The volume decline reflected lower pulp board, lumber, kaolin, printing paper, and wood chip shipments due to reduced U.S. paper production and the slowdown in the housing market.

For 2011, paper, clay, and forest products revenues are expected to be modestly higher as increased average revenue per unit is expected to be offset in part by reduced shipments of woodchips, pulp board, kaolin, pulp, and newsprint due to customer sourcing changes and the continued weak demand for paper.

K24

Automotive revenues rose 23%, compared to 2009. A network redesign that eliminated reloadings at mixing centers resulted in fewer carloads and higher revenue per unit. Approximately 33,200 carloads were eliminated in 2010 as a result of the design changes in the automotive network. This reduction in carloadings was completely offset by higher volumes associated with the 40% increased production of North American light vehicles.

In 2009, automotive revenues decreased 36%, compared to 2008, reflecting lower traffic volumes and decreased average revenue per unit as fuel surcharges were lower. Volumes decreased 30%, primarily as a result of a 32% decrease in North American light vehicle production as manufacturers cut production in line with consumer demand.

For 2011, automotive revenues are expected to increase, driven by volume gains due to a projected increase in North American light vehicle production, in addition to higher average revenue per unit related to rate increases from escalators and contract renegotiation.

INTERMODAL revenues increased $266 million, or 17%, compared with 2009, reflecting a 16% increase in traffic volume and a 1% improvement in average revenue per unit. In 2010, all intermodal segments experienced volume increases, reflecting a steadily improving economy as well as an increase in market demand. Domestic volume (which includes truckload and intermodal marketing companies’ volumes) increased 27%; international traffic volume improved 7%; premium business, which includes parcel and less-than-truckload (LTL) carriers, increased 16%; and Triple Crown Services (Triple Crown), a service with rail-to-highway trailers, experienced a 5% growth in volume.

In 2009, intermodal revenues decreased $528 million, or 26%, compared with 2008, reflecting a 16% reduction in traffic volume and an 11% decrease in average revenue per unit. In 2009, all intermodal segments experienced depressed volumes, reflecting the weak economy and lower consumer demand. International traffic volume declined 30%; premium business decreased 14%; Triple Crown experienced a 10% drop in volume; and domestic volume decreased less than 1%.

For 2011, intermodal revenues are expected to increase due to higher average revenue per unit and volumes as a result of steadily improving economy and an increase in market demand.

Railway Operating Expenses

Railway operating expenses in 2010 were $6.8 billion, up $833 million, or 14% compared to 2009. Expenses in 2009 were $6 billion, down $1.6 billion, or 21% compared to 2008. The increase in 2010 was primarily due to increased volume-related expenses and higher fuel prices. The decrease in 2009 was primarily due to lower volume-related expenses and lower fuel prices. The railway operating ratio, which measures the percentage of operating revenues consumed by operating expenses, improved to 71.9% in 2010, compared with 75.4% in 2009 and 71.1% in 2008.

K25

The following table shows the changes in railway operating expenses summarized by major classifications.

Operating Expense Variances
Increases (Decreases)

		2010 vs. 2009		2009 vs. 2008
		($ in millions)

Compensation and benefits	$	307	$	(283)
Purchased services and rents		74		(196)
Fuel		354		(913)
Depreciation		(18)		33
Materials and other		116		(211)
Net Increase (Decrease)	$	833	$	(1,570)

Compensation and benefits, which represents 40% of total operating expenses, increased $307 million, or 13% compared with 2009. The rise was principally the result of higher:

employee activity levels associated with increased traffic volumes (up $88 million),
health and welfare benefit costs for active and retired employees (up $67 million),
wage rates (up $51 million),
incentive and stock-based compensation (up $48 million),
pension expenses (up $30 million), and
payroll taxes (up $19 million).

In 2009, compensation and benefits decreased $283 million, or 11%, compared with 2008, primarily due to lower volume-related payroll (down $217 million); reduced incentive and stock-based compensation (down $117 million); the absence of the cost of lump-sum payments due under the 2008 Brotherhood of Locomotive Engineers and Trainmen (BLET) agreement ($31 million); and, lower payroll taxes (down $26 million). These decreases were partially offset by increased wage rates (up $53 million); increased pension costs (up $42 million); and higher medical benefits (up $25 million).

NS employment averaged 28,559 in 2010, compared with 28,593 in 2009 and 30,709 in 2008. Looking forward to 2011, NS expects employment levels to be more in-line with 2008 employment levels and accordingly, increased compensation and benefits expenses as a result of anticipated volume increases and expected higher health and welfare benefit rates ($30 million) for agreement employees.

Purchased services and rents includes the costs of services purchased from outside contractors, including the net costs of operating joint (or leased) facilities with other railroads and the net cost of equipment rentals. This category of expenses increased $74 million, or 5%, in 2010 compared to 2009, but decreased $196 million, or 12%, in 2009 compared to 2008.

Purchased services costs were $1.2 billion in 2010, $1.1 billion in 2009, and $1.2 billion in 2008. The increase in 2010 was driven by higher costs associated with volume-related services. The decrease in 2009 reflected lower volume-related expenses such as transportation operating costs (including automotive-related costs and crew transportation expenses), intermodal operations costs, and mechanical and engineering expenses (largely because of reduced maintenance activities). These declines were offset in part by increased professional and legal services.

Equipment rents, which includes the cost to NS of using equipment (mostly freight cars) owned by other railroads or private owners less the rent paid to NS for the use of its equipment, amounted to $326 million, $316 million, and $357 million for 2010, 2009, and 2008, respectively. The increase in 2010 was principally due to higher traffic volumes, whereas the decrease in 2009 was principally due to lower traffic volumes.

K26

Fuel expense, which includes the cost of locomotive fuel as well as other fuel used in railway operations, increased $354 million, or 49%, in 2010, compared with 2009, but decreased $913 million, or 56%, in 2009, compared with 2008. The increase in 2010 was principally the result of higher fuel prices (locomotive fuel prices increased 33%) which had an effect of $271 million, as well as increased fuel consumption (locomotive fuel consumption rose 12%) which had an effect of $83 million. The decline in 2009 reflected lower fuel prices, which had an impact of $600 million, and reduced fuel consumption, which had an impact of $313 million. In 2009, locomotive fuel prices declined 47%, and locomotive fuel consumption fell 19% in 2009.

Depreciation expense decreased $18 million, or 2%, in 2010 compared to 2009, but increased $33 million, or 4%, in 2009 compared to 2008. The decrease in 2010 reflects lower depreciation rates resulting from the equipment study that was completed in the first quarter of 2010, which more than offset the effects of NS’ increased roadway and equipment capital base.

The increase in 2009 was a reflection of substantial capital investments and improvements.

Materials and other expenses (including the estimates of costs related to personal injury, property damage, and environmental matters) increased $116 million, or 18%, in 2010 compared with 2009, but decreased $211 million, or 25%, in 2009 compared with 2008, as shown in the following table.

		2010		2009		2008
		($ in millions)

Materials	$	346	$	309	$	380
Casualties and other claims		142		102		180
Other		269		230		292
Total	$	757	$	641	$	852

The increase in 2010 reflected increased locomotive and roadway materials expenses, reduced favorable personal injury claims development, the absence of the $21 million favorable settlement of a multi-year tax dispute that benefited 2009, and higher costs associated with supplies, employee travel, derailments, environmental remediation, and property taxes.

The decrease in 2009 reflected lower locomotive, freight car, and roadway materials expenses, lower loss and damage claims, favorable personal injury claims development, reduced employee travel costs, a $21 million favorable adjustment related to settlement of a multi-year state tax dispute, and the absence of the 2008 Avondale Mills settlement (see additional discussion below).

In 2011, NS expects materials expenses for locomotive and railcar equipment to increase by approximately $55 million due to higher traffic volumes.

In April 2008, NS settled the lawsuit brought by Avondale Mills for claims associated with the January 6, 2005 derailment in Graniteville, SC. A portion of the settlement was not reimbursed by insurance and was included in 2008 expenses. The total liability related to the derailment represents NS’ best estimate based on current facts and circumstances. The estimate includes amounts related to property damage, personal injury and response costs. NS’ commercial insurance policies are expected to cover substantially all expenses related to this derailment above the unreimbursed portion and NS’ self-insured retention, including NS’ response costs and legal fees. The Consolidated Balance Sheets reflect long-term receivables for estimated recoveries from NS’ insurance carriers. NS engaged in arbitration with two of its insurance carriers that failed to respond to insurance claims submitted by NS. During the first quarter of 2010, NS settled the arbitration claim ($100 million) with one of the insurance carriers with no adverse effect on NS’ financial position, results of operations, or liquidity. The remaining insurance claim was arbitrated in December 2010. NS is currently awaiting a ruling from the a rbitration panel. NS believes that the arbitration panel will rule in favor of NS and recovery of the recorded receivables for the contested portion ($43 million) is probable.

The largest component of casualties and other claims expense is personal injury costs. Cases involving occupational injuries comprised about 44% of total employee injury cases resolved and about 31% of total employee injury payments made. With its long-established commitment to safety, NS continues to work actively to eliminate all employee injuries and to reduce the associated costs. With respect to occupational injuries, which are not caused by a specific accident or event but allegedly result from a claimed exposure over time, the benefits of any existing safety initiatives may not be realized immediately. The majority of these types of claims are being asserted by former or retired employees, some of whom have not been actively employed in the rail industry for decades. The rail industry remains uniquely susceptible to litigation involving job-related accidental injury and occupational claims because of the Federal Employers’ Li ability Act (FELA), which is applicable only to railroads. FELA’s fault-based system, which covers employee claims for job-related injuries, produces results that are unpredictable and inconsistent as compared with a no-fault workers’ compensation system.

K27

NS maintains substantial amounts of insurance for potential third-party liability and property damage claims. It also retains reasonable levels of risk through self-insurance (see Note 17). NS expects insurance costs to be slightly lower in 2011.

Other Income – Net

Other income – net was $153 million in 2010, $127 million in 2009, and $110 million in 2008 (see Note 2). The increase in 2010 reflected higher gains on the sale of property, including a $35 million gain on the sale of land to the City of Virginia Beach, Virginia and a $13 million favorable coal royalty settlement. These increases were offset in part by increased interest expense (net) on uncertain tax positions and other tax contingencies (which includes the absence of 2009 favorable resolution of prior years’ tax matters).

The increase in 2009 reflected higher net returns from corporate-owned life insurance (up $32 million) offset in part by fewer gains on the sale of property (down $11 million).

Income Taxes

Income tax expense in 2010 was $871 million, for an effective rate of 37%, compared with effective rates of 36% in 2009 and 38% in 2008. The increase in the rate for 2010 was primarily due to a $27 million charge to deferred tax expense due to a change in the tax law impacting the Medicare Part D retiree drug subsidy program, a lower benefit from Conrail equity, and an increase in state taxes, offset in part by a $34 million benefit resulting from a change in estimate related to NS’ deferred taxes. The decrease in the rate for 2009 was primarily due to improved net returns from corporate-owned life insurance and the favorable resolution of state tax issues.

Fifty-percent bonus depreciation was allowed for federal income taxes for 2008 through 2010. In December 2010, the Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act increased bonus depreciation to 100 percent for the period September 2010 through the end of 2011 and allows 50 percent bonus depreciation in 2012. Bonus depreciation does not have a material effect on NS’ total provision for income taxes or effective tax rate, but does significantly lower current tax expense and the related cash outflows for income taxes paid.

NS’ consolidated federal income tax return for 2008 is being audited by the IRS.

K28

FINANCIAL CONDITION, LIQUIDITY, AND CAPITAL RESOURCES

Cash provided by operating activities, NS’ principal source of liquidity, was $2.7 billion in 2010 compared with $1.9 billion in 2009 and $2.7 billion in 2008. The increase in 2010 reflects the improvement in operating results, in addition to a reduction in working capital components. Operating cash flows in 2010 also benefited from the favorable settlement of an insurance claim related to the 2005 Graniteville derailment. The decline in 2009 reflected the $1.1 billion decrease in income from railway operations offset in part by lower income tax payments. NS had working capital of $389 million at December 31, 2010, compared with working capital of $457 million at December 31, 2009. NS’ portfolio of cash, cash equivalents, and short-term investment balances totaled $1.1 billion at both December 31, 2010 and 2009 and was invested in accordance with NS’ corporate investment policy as approved by the Board of Directors. &n bsp;The portfolio contains securities that are subject to market risk. There are no limits or restrictions on NS’ access to these assets. NS expects that cash on hand combined with cash provided by operating activities will be sufficient to meet its ongoing obligations.

Contractual obligations at December 31, 2010, comprised of NS’ long-term debt (including capital leases) (see Note 8), operating leases (see Note 9), agreements with CRC and long-term advances from Conrail (see Note 5), unconditional purchase obligations (see Note 17), and unrecognized tax benefits (see Note 3), were as follows:

Off balance sheet arrangements consist of obligations related to operating leases, which are included in the table of contractual obligations above and disclosed in Note 9.

Cash used in investing activities was $1.5 billion in both 2010 and 2009 and $1.2 billion in 2008. In 2010, additional capital expenditures were offset by lower net investment activity. The increase in 2009 primarily reflected lower proceeds from investment sales and higher investment purchases, offset in part by lower property additions.

K29

Property additions account for most of the recurring spending in this category. The following tables show capital spending (including capital leases) and track and equipment statistics for the past five years.

For 2011, NS has budgeted $2.2 billion for capital expenditures. The anticipated spending includes $763 million for roadway projects, including the normalized replacement of rail, ties and ballast, and the improvement or replacement of bridges. Planned equipment spending of $701 million includes the acquisition of new locomotives, coal cars, grain covered hopper cars, and intermodal containers and chassis. Equipment spending also includes continued improvements to the locomotive fleet, including the rebuild and upgrade of existing units. Investments in facilities and terminals is anticipated to be $244 million, primarily for intermodal terminals and equipment to add capacity to the intermodal network, including the Crescent Corridor program of projects, and bulk transfer facilities and mechanical service shops. Technology investments of $96 million are planned for new or upgraded systems and computers. NS also expects to spen d $79 million on infrastructure investments, including the MidAmerica and Crescent Corridors. NS has budgeted $146 million for 2011 for the continued implementation of positive train control and expects additional capital expenditures of at least $1 billion in the years 2012 through 2015. This includes upgrades to systems and track structure, required for the Federal Railroad Administration approved implementation of positive train control, that will be accelerated from future years’ spending to meet the 2015 legislative deadline. All capital expenditures are expected to be made with internally generated funds or proceeds from borrowings.

The CREATE project is a public-private partnership to reduce rail and highway congestion and add freight and passenger capacity in the metropolitan Chicago area. NS and other railroads have agreed to participate in CREATE. A portion of public funding has been approved. The CREATE partners have developed a list of projects to be included in Phase I of CREATE. A total of $91 million in federal funding has been secured for Phase I. The railroads have contributed an additional $116 million and expect to complete Phase I by the end of 2012. In addition, $133 million from the High Speed Rail Program and $100 million from the TIGER Stimulus Program have been committed to specific CREATE projects. The State of Illinois and City of Chicago have also committed $14 million in additional funding. As currently planned, the total CREATE project is estimated to cost $3.2 billion with city, state, and federal support.&nb sp; If additional public funding is secured, the railroads are expected to contribute a total of $171 million towards the entire project. NS expects to spend approximately $10 million in 2011 related to the CREATE projects.

The Meridian Speedway is a 320-mile rail line between Meridian, Mississippi and Shreveport, Louisiana. On May 1, 2006, NS and Kansas City Southern (KCS) formed a joint venture, Meridian Speedway LLC (MSLLC), pursuant to which NS agreed to contribute $300 million in cash, substantially all of which will be used for capital improvements in exchange for a 30% interest in the joint venture. To date, NS has contributed $283 million. At the formation of MSLLC, KCS contributed the Meridian Speedway. The joint venture increases capacity and is designed to improve service over the Meridian Speedway into the Southeast.

Pan Am Southern LLC (PAS) is a railroad company joint venture in which NS and Pan Am Railways, Inc. (Pan Am) each has a 50% equity interest. As of December 31, 2010, NS has contributed cash and other property with a combined value of approximately $116 million and committed to contribute an additional $24 million in cash over the next two years. A significant portion of NS’ contributions has and will continue to be used for capital improvements to the PAS Lines and the related construction of new intermodal and automotive terminals.

The Crescent Corridor consists of a program of projects for infrastructure and other facility improvements geared toward creating a seamless, high-capacity intermodal route spanning 11 states from New Jersey to Louisiana and offering truck-competitive service along several major interstate highway corridors, including I-81, I-85, I-20, I-40, I-59, I-78, and I-75. Based on the public benefits that stand to be derived in the form of highway congestion relief, NS plans to implement certain elements of the Crescent Corridor program of projects through a series of public-private partnerships. Currently, the Crescent Corridor has received or expects to receive a total of $210 million in public capital funding commitments from the Commonwealths of Pennsylvania and Virginia, the states of Alabama and Tennessee, the federal TIGER Stimulus Program and other federal funding sources related to projects in Alabama, Pennsylvania, Tennessee, and North Carolina. NS currently estimates spending up to $207 million for the substantial completion of work on these projects which is expected in 2012, including planned 2011 capital expenditures as high as $70 million.

The MidAmerica Corridor is a proposed cooperative arrangement between NS and Canadian National Railway (CN) to effectively share track between Chicago, St. Louis, Kentucky, and Mississippi in order to establish more efficient routes for traffic moving between the midwestern and southeastern U.S., including potential coal traffic moving to NS-served southeastern utility plants from CN-served Illinois Basin coal producers. To implement the MidAmerica Corridor, NS will continue to expend funds to upgrade the rail line operated by West Tennessee Railway between Fulton, Kentucky, and Corinth, Mississippi, a line over which NS would operate pursuant to recently obtained trackage rights. In addition, NS will construct a connection with CN east of St. Louis. Implementation of the MidAmerica corridor arrangement will begin in 2011 with the start of a daily train between St. Louis and the Southeast. Projected capital improvements for 2011 are expected to be a pproximately $17 million.

Cash used in financing activities was $1.4 billion 2010, compared with $31 million in 2009, and $1.1 billion in 2008. The change in 2010 reflected the resumed repurchase and retirement of Common Stock as part of NS’ share repurchase program, in addition to lower borrowings, net of debt repayments. The change in 2009 reflected the absence of share repurchase activity and higher borrowings net of debt repayments that were offset in part by fewer exercises of employee stock options and increased dividends.

Share repurchases totaled $863 million in 2010, zero in 2009, and $1.1 billion in 2008 for the purchase and retirement of 14.7 million, zero, and 19.4 million shares, respectively. On July 27, 2010, NS’ Board of Directors authorized the repurchase of up to an additional 50 million shares of Common Stock through December 31, 2014. The timing and volume of future share repurchases will be guided by management’s assessment of market conditions and other pertinent factors. Any near-term purchases under the program are expected to be made with internally generated cash or proceeds from borrowings.

During the third quarter 2010, NS issued $250 million of unsecured notes at 6.00% due 2105.

As of December 31, 2010, NS has authority from its Board of Directors to issue an additional $1 billion of debt or equity securities through public or private sale. NS has on file with the Securities and Exchange Commission a Form S-3 automatic shelf registration statement for well-known seasoned issuers under which securities may be issued pursuant to this authority.

NS also has in place and available a $1 billion, five-year credit agreement expiring in 2012, which provides for borrowings at prevailing rates and includes covenants. NS had no amounts outstanding under this facility at December 31, 2010, and NS is in compliance with all of its covenants. In October 2010, NS renewed its $350 million accounts receivable securitization program with a 364-day term to run until October 2011. There was $200 million outstanding under this program at December 31, 2010 (see Note 8).

Looking forward, NS’ annual debt maturities are relatively modest (see Note 8). Overall, NS’ goal is to maintain a capital structure with appropriate leverage to support NS’ business strategy and provide flexibility through business cycles.

APPLICATION OF CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. These estimates and assumptions may require significant judgment about matters that are inherently uncertain, and future events are likely to occur that may require management to make changes to these estimates and assumptions. Accordingly, management regularly reviews these estimates and assumptions based on historical experience, changes in the business environment, and other factors that management believes to be reasonable under the circumstances. Management regularly discusses the development, selection, and disclosures concerning critical accounting estimates with the Aud it Committee of its Board of Directors.

K32

Pensions and Other Postretirement Benefits

Accounting for pensions and other postretirement benefit plans requires management to make several estimates and assumptions (see Note 11). These include the expected rate of return from investment of the plans’ assets, projected increases in medical costs, and the expected retirement age of employees as well as their projected earnings and mortality. In addition, the amounts recorded are affected by changes in the interest rate environment because the associated liabilities are discounted to their present value. Management makes these estimates based on the company’s historical experience and other information that it deems pertinent under the circumstances (for example, expectations of future stock market performance). Management utilizes an independent consulting actuarial firm’s studies to assist it in selecting appropriate assumptions and valuing its related liabilities.

NS’ net pension expense, which is included in “Compensation and benefits” in its Consolidated Statements of Income, was $31 million for the year ended December 31, 2010. In recording this amount, NS assumed a long-term investment rate of return of 8.75%, which was supported by the long-term total rate of return on plan assets since inception. A one percentage point change to this rate of return assumption would result in a $16 million change in pension expense, and, as a result, an equal change in “Compensation and benefits” expense. Changes that are reasonably likely to occur in assumptions concerning retirement age, projected earnings, and mortality would not be expected to have a material effect on NS’ net pension expense or net pension liability in the future. The net pension liability is recorded at its net present value using a discount rate that is based on the current interest rate environment in light of the timing of expected benefit payments. NS utilizes analyses in which the projected annual cash flows from the pension and postretirement benefit plans are matched with yield curves based on an appropriate universe of high-quality corporate bonds. NS uses the results of the yield curves to select the discount rates that match the payment streams of the benefits in these plans.

NS’ net cost for other postretirement benefits, which is also included in “Compensation and benefits,” was $114 million for the year ended December 31, 2010. In recording this expense and valuing the net liability for other postretirement benefits, which is included in “Other postretirement benefits,” management estimated future increases in health-care costs. These assumptions, along with the effect of a one percentage point change in them, are described in Note 11.

Properties and Depreciation

Most of NS’ total assets are long-lived railway properties (see Note 6). As disclosed in Note 1, NS’ properties are depreciated using group depreciation. The primary depreciation method for NS’ asset base is group life. Units of production is the principal method of depreciation for rail in high density corridors and for depletion of natural resources. Remaining properties are depreciated generally using the straight-line method over the lesser of estimated service or lease lives.

NS’ depreciation expense is based on management’s assumptions concerning expected service lives of its properties as well as the expected net salvage that will be received upon their retirement. In developing these assumptions, NS’ management utilizes periodic depreciation studies that are performed by an independent outside firm of consulting engineers and approved by the Surface Transportation Board (“STB”), the regulatory board that has broad jurisdiction over railroad practices. NS’ depreciation studies are conducted every three years for equipment and every six years for track assets and other roadway property. The frequency of these studies correlates with guidelines established by the STB. Key factors which are considered in developing average service life and salvage estimates include:

Statistical analysis of historical retirement data and surviving asset records;
Review of historical salvage received and current market rates;
Review of NS’ operations including expected changes in technology, customer demand, maintenance practices and asset management strategies;
Review of accounting policies and assumptions; and
Industry review and analysis.

The units of production depreciation rate for rail in high density corridors is derived based on consideration of annual gross ton miles as compared to the total or ultimate capacity of rail in these corridors. NS’ experience has shown that traffic density is a leading factor in determination of the expected service life of rail in high density corridors. In developing the respective depreciation rate, consideration is also given to several rail characteristics including age, weight, condition (new or second hand) and type (curve or tangent). As a result, a composite depreciation rate is developed which is applied to the depreciable base.

NS’ recent experience with these studies has been that while they do result in changes in the rates used to depreciate its properties, these changes have not caused a significant effect to its annual depreciation expense. Changes in rates as a result of depreciation studies are implemented prospectively. These studies may also indicate that the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by the study. Any such deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the affected class of property, as determined by the study. NS’ depreciation expense for the year ended December 31, 2010, amounted to $819 million. NS’ composite depreciation rates for 2010 are disclosed in Note 6; a one-tenth percentage point increase (or decrease) in these rates would have resulted in a $30 million increase (or decrease) to depreciation expense.&nb sp; For 2010, roadway depreciation rates ranged from 0.83% to 33.3% and equipment depreciation rates ranged from 1.32% to 37.84%.

K33

When properties other than land and nonrail assets are sold or retired in the ordinary course of business, the cost of the assets, net of sale proceeds or salvage, is charged to accumulated depreciation, and no gain or loss is recognized in earnings. Actual historical cost values are retired when available, such as with equipment assets. The use of estimates in recording the retirement of certain roadway assets is necessary based on the impracticality of tracking individual asset costs. When retiring rail, ties, and ballast, NS uses statistical curves that indicate the relative distribution of the age of the assets retired. The historical cost of other roadway assets is estimated using a combination of inflation indices specific to the rail industry and those published by the U.S. Bureau of Labor Statistics. The indices are applied to the replacement value based on the age of the retired assets. These indices are used because they closely c orrelate with the costs of roadway assets. Gains and losses on disposal of land and nonrail assets are included in “Other income – net” (see Note 2) since such income is not a product of NS’ railroad operations.

A retirement is considered abnormal if it does not occur in the normal course of business, if it relates to disposition of a large segment of an asset class and if the retirement varies significantly from the retirement profile identified through our depreciation studies, which inherently consider the impact of normal retirements on expected service lives and depreciation rates. Gains or losses from abnormal retirements are recognized in earnings. There were no gains or losses recognized in 2010, 2009, or 2008, due to abnormal retirement of depreciable railroad property.

NS reviews the carrying amount of properties whenever events or changes in circumstances indicate that such carrying amount may not be recoverable based on future undiscounted cash flow. Assets that are deemed impaired as a result of such review are recorded at the lesser of carrying amount or fair value.

Personal Injury, Environmental, and Legal Liabilities

NS’ expense for casualties and other claims, included in “Materials and other,” amounted to $142 million for the year ended December 31, 2010. Most of this expense was NS’ accrual related to personal injury liabilities. Job-related personal injury and occupational claims are subject to FELA, which is applicable only to railroads. FELA’s fault-based tort system produces results that are unpredictable and inconsistent as compared with a no-fault worker’s compensation system. The variability inherent in this system could result in actual costs being very different from the liability recorded. In all cases, NS records a liability when the expected loss for the claim is both probable and estimable.

To aid in valuing its personal injury liability and determining the amount to accrue during each period, NS’ management utilizes studies prepared by an independent consulting actuarial firm. For employee personal injury cases, the actuarial firm studies NS’ historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences. An estimate of the the ultimate amount of the liability, which includes amounts for incurred but unasserted claims, is based on the results of this analysis. For occupational injury claims, the actuarial firm studies NS’ history of claim filings, severity, payments and other relevant facts. Additionally, the estimate of the ultimate loss for occupational injuries includes a provision for those claims that have been incurred but not reported by projecting NS’ experience into the future as far as can be reasonably determined. NS has recorded this actu arially determined liability. The liability is dependent upon many individual judgments made as to the specific case reserves as well as the judgments of the consulting actuary and management in the periodic studies. Accordingly, there could be significant changes in the liability, which NS would recognize when such a change became known. While actuarial studies reflected favorable claims development between 2008 and 2009 (resulting in a decrease of the annual cost related to personal injuries from $78 million to $51 million), a reduced level of favorable development in 2010 resulted in an increase in the annual cost related to personal injuries to $75 million in 2010 from $51 million in 2009. While the liability recorded is supported by the most recent study, it is possible that the ultimate liability could be higher or lower.

NS is subject to various jurisdictions’ environmental laws and regulations. It is NS’ policy to record a liability where such liability or loss is probable and its amount can be estimated reasonably (see Note 17). Claims, if any, against third parties for recovery of cleanup costs incurred by NS, are reflected as receivables (when collection is probable) in the Consolidated Balance Sheets and are not netted against the associated NS liability. Environmental engineers regularly participate in ongoing evaluations of all known sites and in determining any necessary adjustments to liability estimates. NS also has established an Environmental Policy Council, composed of senior managers, to oversee and interpret its environmental policy.

Operating expenses for environmental matters totaled approximately $26 million in 2010, $20 million in 2009, and $18 million in 2008, and capital expenditures for environmental matters totaled approximately $8 million in 2010, $11 million in 2009, and $7 million in 2008. Capital expenditures for environmental matters in 2011 are expected to be about $9 million.

NS’ Consolidated Balance Sheets included liabilities for environmental exposures in the amount of $33 million at December 31, 2010, and $32 million at December 31, 2009 (of which $12 million is classified as a current liability at the end of each period). At December 31, 2010, the liability represents NS’ estimate of the probable cleanup and remediation costs based on available information at 143 known locations. As of that date, 11 sites accounted for $15 million of the liability, and no individual site was considered to be material. NS anticipates that much of this liability will be paid out over five years; however, some costs will be paid out over a longer period.

At 32 locations, one or more NS subsidiaries, usually in conjunction with a number of other parties, have been identified as potentially responsible parties by the Environmental Protection Agency (EPA) or similar state authorities under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, or comparable state statues, which often impose joint and several liability for cleanup costs.

K34

With respect to known environmental sites (whether identified by NS or by the EPA or comparable state authorities), estimates of NS’ ultimate potential financial exposure for a given site or in the aggregate for all such sites are necessarily imprecise because of the widely varying costs of currently available cleanup techniques, the likely development of new cleanup technologies, the difficulty of determining in advance the nature and full extent of contamination and each potential participant’s share of any estimated loss (and that participant’s ability to bear it), and evolving statutory and regulatory standards governing liability. NS estimates its environmental remediation liability on a site-by-site basis, using assumptions and judgments that management deems appropriate for each site. As a result, it is not practical to quantitatively describe the effects of changes in these many assumptions and judgments. NS has consistently applied i ts methodology of estimating its environmental liabilities.

Based on its assessment of the facts and circumstances now known, management believes that it has recorded the probable costs for dealing with those environmental matters of which NS is aware. Further, management believes that it is unlikely that any known matters, either individually or in the aggregate, will have a material adverse effect on NS’ financial position, results of operations, or liquidity.

Norfolk Southern and certain subsidiaries are defendants in numerous lawsuits and other claims relating principally to railroad operations. When management concludes that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to expenses. While the ultimate amount of liability incurred in any of these lawsuits and claims is dependent on future developments, in management’s opinion the recorded liability, if any, is adequate to cover the future payment of such liability and claims. However, the final outcome of any of these lawsuits and claims cannot be predicted with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. Any adjustments to recorded liabilities will be reflected in expenses in the periods in which such adjustments are known.

Income Taxes

NS’ net long-term deferred tax liability totaled $7.1 billion at December 31, 2010 (see Note 3). This liability is estimated based on the expected future tax consequences of items recognized in the financial statements. After application of the federal statutory tax rate to book income, judgment is required with respect to the timing and deductibility of expenses in the corporate income tax returns. For state income and other taxes, judgment is also required with respect to the apportionment among the various jurisdictions. A valuation allowance is recorded if management expects that it is more likely than not that its deferred tax assets will not be realized. NS had a $21 million valuation allowance on $823 million of deferred tax assets as of December 31, 2010, reflecting the expectation that most of these assets will be realized. During 2010, NS performed a review and re-evaluation of its estimates for deferred tax ass ets and liabilities, resulting in a reduction of income tax expense of $34 million.

In addition, NS has a recorded liability for its estimate of uncertain tax positions taken or expected to be taken in a tax return. Judgment is required in evaluating the application of federal and state tax laws and assessing whether it is more likely than not that a tax position will be sustained on examination and, if so, judgment is also required as to the measurement of the amount of tax benefit that will be realized upon settlement with the taxing authority. Management believes this liability for uncertain tax positions to be adequate. Income tax expense is adjusted in the period in which new information about a tax position becomes available or the final outcome differs from the amounts recorded. For every one half percent change in the 2010 effective tax rate, net income would have changed by $12 million.

K35

OTHER MATTERS

Labor Agreements

More than 80% of NS’ railroad employees are covered by collective bargaining agreements with various labor unions. These agreements remain in effect until changed pursuant to the Railway Labor Act (RLA). NS largely bargains nationally in concert with other major railroads. Moratorium provisions in the labor agreements govern when the railroads and the unions may propose changes.

On or after November 1, 2009, NS and the nation’s other major railroads represented by the National Carriers Conference Committee (NCCC) served new proposals to begin the current round of bargaining. The NCCC and a coalition of six unions led by the Transportation Communications Union (TCU) are currently negotiating with the assistance of a mediator from the National Mediation Board. On January 12, 2011, the National Mediation Board accepted the application for mediation filed on behalf of the Rail Labor Bargaining Coalition, representing six labor organizations in national bargaining, and a mediator has been assigned. The outcome of any of the negotiations cannot be determined at this point.

The current agreements with the Brotherhood of Locomotive Engineers and Trainmen (BLET) and the American Train Dispatchers Association (ATDA) extend through 2014. Because NS has reached separate agreements with the BLET and the ATDA, only the health and welfare provisions from the national agreements apply to NS’ locomotive engineers and ATDA-represented dispatchers. NS bargains separately with longshoremen, who are represented by the International Longshoremen’s Association (ILA), at Ashtabula (Ohio) Docks and do not participate in national bargaining.

Market Risks and Hedging Activities

NS manages its overall exposure to fluctuations in interest rates by issuing both fixed- and floating-rate debt instruments and by entering into interest-rate hedging transactions to achieve an appropriate mix within its debt portfolio.

At December 31, 2010, NS’ debt subject to interest rate fluctuations totaled $200 million. A 1% point increase in interest rates would increase NS’ total annual interest expense related to all its variable debt by approximately $2 million. Management considers it unlikely that interest rate fluctuations applicable to these instruments will result in a material adverse effect on NS’ financial position, results of operations, or liquidity.

At December 31, 2010, NS did not have fixed rate capital leases that were converted to variable rate obligations using interest rate swap agreements. At December 31, 2009, some of NS’ capital leases, which carried an average fixed rate of 7%, were effectively converted to variable rate obligations using interest rate swap agreements. On December 31, 2009, the average pay rate under these agreements was 1%, and the average receive rate was 6%. During 2010 and 2009, the effect of the swaps was to reduce interest expense by less than $1 million in both periods. A portion of the lease obligation was payable in Japanese yen. NS eliminated the associated exchange rate risk at the inception of each lease with a yen deposit sufficient to fund the yen-denominated obligation. Most of these deposits are held by foreign banks, primarily Japanese. As a result, NS is exposed to financial market risk relative to Japan. & nbsp;Counterparties to the interest rate swaps and Japanese banks holding yen deposits are major financial institutions believed by management to be creditworthy.

Inflation

In preparing financial statements, U.S. generally accepted accounting principles require the use of historical cost that disregards the effects of inflation on the replacement cost of property. NS, a capital-intensive company, has most of its capital invested in such property. The replacement cost of these assets, as well as the related depreciation expense, would be substantially greater than the amounts reported on the basis of historical cost.

K36

Proposed Legislation and Regulations on Safety and Transportation of Hazardous Materials

Federal regulations were adopted in late 2008 on safety and transportation of hazardous materials. NS is in compliance with those regulations.

FORWARD-LOOKING STATEMENTS

This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements that may be identified by the use of words like “believe,” “expect,” “anticipate,” and “project.” Forward-looking statements reflect management’s good-faith evaluation of information currently available.

However, such statements are dependent on and, therefore, can be influenced by, a number of external variables over which management has little or no control, including: legislative and regulatory developments; transportation of hazardous materials as a common carrier by rail; acts of terrorism or war; general economic conditions; impacts of environmental regulations on utility coal customers and/or the value of certain NS assets; competition and consolidation within the transportation industry; the operations of carriers with which NS interchanges; disruptions to NS’ technology infrastructure, including computer systems; labor difficulties, including strikes and work stoppages; commercial, operating, environmental, and climate change legislative and regulatory developments; results of litigation; natural events such as severe weather, hurricanes, and floods; unavailability of qualified personnel due to unpredictability of demand for rail services; fluctuation in supplies a nd prices of key materials, in particular diesel fuel; and changes in securities and capital markets. For a discussion of significant risk factors applicable to NS, see Part I, Item 1A “Risk Factors.” Forward-looking statements are not, and should not be relied upon as, a guarantee of future performance or results, nor will they necessarily prove to be accurate indications of the times at or by which any such performance or results will be achieved. As a result, actual outcomes and results may differ materially from those expressed in forward-looking statements. NS undertakes no obligation to update or revise forward-looking statements.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Norfolk Southern Corporation:

We have audited Norfolk Southern Corporation’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Norfolk Southern Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Norfolk Southern Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Norfolk Southern Corporation and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2010, and our report dated February 16, 2011 expressed an unqualified opinion on those consolidated financial statements.

We have audited the accompanying consolidated balance sheets of Norfolk Southern Corporation and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2010. In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule as listed in Item 15(A)2. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Norfolk Southern Corporation and subsidiaries as of December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Norfolk Southern Corporation’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 16, 2011 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Norfolk Southern Corporation and Subsidiaries
Notes to Consolidated Financial Statements

The following Notes are an integral part of the Consolidated Financial Statements.

1. Summary of Significant Accounting Policies

Description of Business

Norfolk Southern Corporation is a Virginia-based holding company engaged principally in the rail transportation business, operating approximately 20,000 route miles primarily in the East and Midwest. These consolidated financial statements include Norfolk Southern Corporation (Norfolk Southern) and its majority-owned and controlled subsidiaries (collectively, NS). Norfolk Southern’s major subsidiary is Norfolk Southern Railway Company (NSR). All significant intercompany balances and transactions have been eliminated in consolidation.

NSR and its railroad subsidiaries transport raw materials, intermediate products and finished goods classified in the following market groups (percent of total railway operating revenues in 2010): coal (28%); intermodal (19%); agriculture/consumer products/government (14%); chemicals (14%); metals/construction (11%); paper/clay/forest products (7%); and, automotive (7%). Although most of NS’ customers are domestic, ultimate points of origination or destination for some of the products transported (particularly coal bound for export and some intermodal containers) may be outside the U.S. More than 80% of NS’ railroad employees are covered by collective bargaining agreements with various labor unions.

Use of Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management periodically reviews its estimates, including those related to the recoverability and useful lives of assets, as well as liabilities for litigation, environmental remediation, casualty claims, income taxes and pension and other postretirement benefits. Changes in facts and circumstances may result in revised estimates.

Revenue Recognition

Transportation revenue is recognized proportionally as a shipment moves from origin to destination and related expenses are recognized as incurred. Refunds (which are primarily volume-based incentives) are recorded as a reduction to revenues on the basis of management’s best estimate of projected liability, which is based on historical activity, current traffic counts and the expectation of future activity. NS regularly monitors its contract refund liability and, historically, the estimates have not differed significantly from the amounts ultimately refunded. Switching, demurrage and other incidental service revenues are recognized when the services are performed.

Derivatives

NS does not engage in the trading of derivatives. NS uses derivative financial instruments in the management of its mix of fixed- and floating-rate debt. Management has determined that these derivative instruments qualify as fair-value hedges, having values that highly correlate with the underlying hedged exposures, and has designated such instruments as hedging transactions. Income and expense related to the derivative financial instruments are recorded in the same category as generated by the underlying asset or liability. Credit risk related to the derivative financial instruments is considered to be minimal and is managed by requiring high credit standards for counterparties and periodic settlements (see Note 16).

Cash Equivalents

“Cash equivalents” are highly liquid investments purchased three months or less from maturity.

Allowance for Doubtful Accounts

NS’ allowance for doubtful accounts was $5 million at both December 31, 2010 and 2009. To determine its allowance for doubtful accounts, NS evaluates historical loss experience (which has not been significant), the characteristics of current accounts, and general economic conditions and trends.

Materials and Supplies

“Materials and supplies,” consisting mainly of fuel oil and items for maintenance of property and equipment, are stated at the lower of average cost or market. The cost of materials and supplies expected to be used in capital additions or improvements is included in “Properties.”

K46

Investments

Debt securities classified as “held-to-maturity” are reported at amortized cost and marketable equity and debt securities classified as “trading” or “available-for-sale” are recorded at fair value. Unrealized after-tax gains and losses for investments designated as “available-for-sale” are recognized in “Accumulated other comprehensive loss.”

Investments where NS has the ability to exercise significant influence over but does not control the entity are accounted for using the equity method, whereby the investment is carried at the cost of the acquisition plus NS’ equity in undistributed earnings or losses since acquisition.

Properties

“Properties” are stated principally at cost and are depreciated using the group method of depreciation whereby assets with similar characteristics, use, and expected lives are grouped together in asset classes and depreciated using a composite depreciation rate. This methodology treats each asset class as a pool of resources, not as singular items. NS uses more than 60 depreciable asset classes. The primary depreciation method for NS’ asset base is group life. Units of production is the principal method of depreciation for rail in high density corridors and for depletion of natural resources (see Note 2). Remaining properties are depreciated generally using the straight-line method over the lesser of estimated service or lease lives. Depreciation in the Consolidated Statements of Cash Flows includes both depreciation and depletion.

Statistical analysis of historical retirement data and surviving asset records;
Review of historical salvage received and current market rates;
Review of NS’ operations including expected changes in technology, customer demand, maintenance practices and asset management strategies;
Review of accounting policies and assumptions; and
Industry review and analysis.

NS’ recent experience with these studies has been that while they do result in changes in the rates used to depreciate its properties, these changes have not caused a significant effect to its annual depreciation expense. Changes in rates as a result of depreciation studies are implemented prospectively. The studies may also indicate that the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by the study. Any such deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the affected class of property, as determined by the study. For 2010, roadway depreciation rates ranged from 0.83% to 33.3% and equipment depreciation rates ranged from 1.32% to 37.84%.

NS capitalizes interest on major capital projects during the period of their construction. Expenditures, including those on leased assets, that extend an assets’ useful life or increase its utility, are capitalized. Expenditures capitalized include those that are directly related to a capital project and may include materials, labor and equipment, in addition to an allocable portion of indirect costs that clearly relate to a particular project. Due to the capital intensive nature of the railroad industry, a significant portion of annual capital spending relates to the replacement of self-constructed assets. Because removal activities occur in conjunction with replacement, removal costs are estimated based on an average percentage of time employees replacing assets spend on removal functions. Costs related to repairs and maintenance activities that do not extend an asset’s useful life or increase its utility are expensed when such repairs a re performed.

When properties other than land and nonrail assets are sold or retired in the ordinary course of business, the cost of the assets, net of sale proceeds or salvage, is charged to accumulated depreciation, and no gain or loss is recognized in earnings. Actual historical cost values are retired when available, such as with equipment assets. The use of estimates in recording the retirement of certain roadway assets is necessary based on the impracticality of tracking individual asset costs. When retiring rail, ties and ballast, NS uses statistical curves that indicate the relative distribution of the age of the assets retired. The historical cost of other roadway assets is estimated using a combination of inflation indices specific to the rail industry and those published by the U.S. Bureau of Labor Statistics. The indices are applied to the replacement value based on the age of the retired assets. These indices are used because they closely co rrelate with the costs of roadway assets. Gains and losses on disposal of land and nonrail assets are included in “Other income – net” (see Note 2) since such income is not a product of NS’ railroad operations.

K47

A retirement is considered abnormal if it does not occur in the normal course of business, if it relates to disposition of a large segment of an asset class and if the retirement varies significantly from the retirement profile identified through our depreciation studies, which inherently consider the impact of normal retirements on expected service lives and depreciation rates. Gains or losses from abnormal retirements are recognized in earnings.

NS reviews the carrying amount of properties whenever events or changes in circumstances indicate that such carrying amount may not be recoverable based on future undiscounted cash flows. Assets that are deemed impaired as a result of such review are recorded at the lower of carrying amount or fair value.

Required Accounting Changes

In June 2009, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 168, “The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles, a replacement of FASB Statement No. 162” (Accounting Standards Update (ASU) 2009-01). This statement, effective for interim and annual periods ending after September 15, 2009, established the FASB Accounting Standards Codification (Codification or ASC) as the single source of authoritative Generally Accepted Accounting Principles (GAAP). SFAS 168 is recognized by the FASB to be applied by nongovernmental entities and stated that all guidance contained in the Codification has an equal level of authority. The authoritative accounting guidance recognized that rules and interpretive releases of the Securities and Exchange Commission (SEC) under federal securities laws are also sources of authoritative GAAP for SEC regist rants. NS adopted the provisions of the authoritative accounting guidance for the interim reporting period ending September 30, 2009, the adoption of which did not have a material effect on NS’ consolidated financial statements.

FASB Staff Position (FSP) No. 132 (R)-1, “Employers’ Disclosures about Postretirement Benefit Plan Assets” (ASC 715-20-65-2), was issued on December 30, 2008. The FSP, effective for fiscal years ending after December 15, 2009, clarifies an employer’s disclosures about plan assets of a defined benefit pension or other postretirement plan. The FSP prescribes expanded disclosures regarding investment allocation decisions, categories of plan assets, inputs, and valuation techniques used to measure fair value, the effect of Level 3 inputs on changes in plan assets and significant concentrations of risk. NS adopted the FSP at the end of 2009 and it did not have a material effect on NS’ consolidated financial statements.

Effective January 1, 2008, NS adopted SFAS No. 157, “Fair Value Measurements” (ASC 820), related to financial instrument assets and liabilities. NS adopted the provisions of this standard relative to nonfinancial assets and nonfinancial liabilities that are not remeasured at fair value on a recurring basis in the first quarter of 2009. This statement, effective for interim or annual reporting periods beginning after November 15, 2007, establishes a framework for measuring fair value in U.S. generally accepted accounting principles and expands disclosures about fair value measurements. Adoption did not have a material effect on NS’ consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160 (SFAS 160), “Noncontrolling Interests in Consolidated Financial Statements” (ASC 810-10), which requires that noncontrolling (minority) interests be reported as a component of equity. NS adopted the statement in the first quarter of 2009 with no material effect on NS’ consolidated financial statements.

In June 2008, the FASB issued FSP Emerging Issues Task Force (EITF) 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities” (ASC 260-10). This FSP addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in the earnings allocation in computing earnings per share under the two-class method as described in SFAS No. 128, “Earnings per Share” (ASC 260-10). NS adopted the FSP, which affects the calculation of earnings per share, in the first quarter of 2009. The provisions of the FSP were applied retrospectively, but did not have a material effect on NS’ consolidated financial statements.

Reconciliation of Statutory Rate to Effective Rate

The “Provision for income taxes” in the Consolidated Statements of Income differs from the amounts computed by applying the statutory federal corporate tax rate as follows:

		2010			2009			2008
		Amount	%		Amount	%		Amount	%
		($ in millions)

Federal income tax at statutory rate	$	828	35	$	568	35	$	963	35

Other, net		(12)	(1)		(19)	(1)		(6)	--

Provision for income taxes	$	871	37	$	588	36	$	1,034	38

During 2010, NS performed a review and re-evaluation of its estimates for deferred tax assets and liabilities, resulting in a reduction of income tax expense of $34 million. In addition, provisions of the health care legislation enacted during 2010 eliminate, after 2012, the tax deduction available for reimbursed prescription drug expenses under the Medicare Part D retiree drug subsidy program. As required by ASC 740, “Income Taxes,” NS recorded a $27 million charge to deferred tax expense in 2010.

Deferred Tax Assets and Liabilities

Certain items are reported in different periods for financial reporting and income tax purposes. Deferred tax assets and liabilities are recorded in recognition of these differences. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows:

		December 31,
		2010		2009
		($ in millions)
Deferred tax assets:
Compensation and benefits, including postretirement	$	617	$	661
Accruals, including casualty and other claims		156		164
Other		50		46
Total gross deferred tax assets		823		871
Less valuation allowance		(21)		(14)
Net deferred tax asset		802		857

Deferred tax liabilities:
Property		(7,453)		(7,195)
Other		(292)		(267)
Total gross deferred tax liabilities		(7,745)		(7,462)

Net deferred tax liability		(6,943)		(6,605)
Net current deferred tax asset		145		142

Net long-term deferred tax liability	$	(7,088)	$	(6,747)

K50

Except for amounts for which a valuation allowance has been provided, management believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets. The valuation allowance at the end of each year primarily relates to subsidiary state income tax net operating losses that may not be utilized prior to their expiration. The total valuation allowance increased $7 million in 2010, $3 million in 2009, and $1 million in 2008.

Uncertain Tax Positions

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

		December 31,
		2010		2009
		($ in millions)

Balance at beginning of year	$	94	$	169

Additions based on tax positions related to the current year		51		25
Additions for tax position of prior years		44		24
Reductions for tax positions of prior years		(19)		(85)
Settlements with taxing authorities		(2)		(22)
Lapse of statutes of limitations		(16)		(17)
Balance at end of year	$	152	$	94

Included in the balance of unrecognized tax benefits at December 31, 2010, are potential benefits of $92 million that would affect the effective tax rate if recognized. Unrecognized tax benefits are adjusted in the period in which new information about a tax position becomes available or the final outcome differs from the amount recorded.

NS expects that the total amount of unrecognized tax benefits at December 31, 2010, will decrease by approximately $34 million in 2011 due to tax positions for which there was an uncertainty about the timing of deductibility in earlier years but deductibility may become certain by the the close of 2011. NS’ consolidated federal income tax return for 2008 is being audited by the Internal Revenue Service (IRS). NS anticipates that the IRS will complete its examination of the 2008 tax year within the next twelve months. State income tax returns generally are subject to examination for a period of three to four years after filing of the return. In addition, NS is generally obligated to report changes in taxable income arising from federal income tax examinations to the states within a period of up to two years from the date the federal examination is final. NS has various state income tax returns either under examination, administrativ e appeals, or litigation. It is reasonably possible that the amount of unrecognized tax benefits will decrease in 2011 as a result of the lapse of state statutes of limitations, but the amount is not expected to be significant. NS does not expect that any of the aforementioned potential changes in unrecognized tax benefits will have a material effect on NS’ financial position, results of operations, or liquidity. In addition, NS has $29 million in unrecognized tax benefits for refund claims for prior years raised by NS during 2010 and $7 million for the same issue for the current year. If resolved favorably, a decrease in these unrecognized tax benefits could reduce income tax expense.

Interest related to unrecognized tax benefits, which is included in “Other income – net,” amounted to $1 million of expense in 2010, $6 million of income in 2009, and $15 million of income in 2008. There were no penalties related to tax matters in 2010, 2009, and 2008. NS has recorded a liability of $14 million at December 31, 2010, and $12 million at December 31, 2009, for the payment of interest on unrecognized tax benefits. NS has no liability recorded at December 31, 2010 and 2009, for the payment of penalties on unrecognized tax benefits.

K51

4. Fair Value

Fair Value Measurements

ASC 820-10, “Fair Value Measurements,” established a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:

Level 1 Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that NS has the ability to access.

Level 2 Inputs to the valuation methodology include:
•Quoted prices for similar assets or liabilities in active markets;
•Quoted prices for identical or similar assets or liabilities in inactive markets;
•Inputs other than quoted prices that are observable for the asset or liability;
•Inputs that are derived principally from or corroborated by observable market data by
correlation or other means.
If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the hierarchy is based on the lowest level of any input that is significant to the fair value measurement. At December 31, 2010 and 2009, for assets measured at fair value on a recurring basis, there were $175 million and $90 million of available-for-sale securities valued under level 2 of the fair value hierarchy, respectively. There were no available-for-sale securities valued under level 1 or level 3 valuation techniques.

In accordance with ASC 825, “Financial Instruments,” NS has evaluated the fair values of financial instruments and methods used to determine those fair values. The fair values of “Cash and cash equivalents,” “Short-term investments,” “Accounts receivable,” “Accounts payable,” and “Short-term debt” approximate carrying values because of the short maturity of these financial instruments. The carrying value of corporate-owned life insurance is recorded at cash surrender value and, accordingly, approximates fair value. The carrying amounts and estimated fair values for the remaining financial instruments, excluding derivatives and investments accounted for under the equity method, consisted of the following at December 31:

		2010				2009
		Carrying		Fair		Carrying		Fair
		Amount		Value		Amount		Value
				($ in millions)

Long-term investments	$	192	$	222	$	237	$	260
Long-term debt	$	(6,925)	$	(7,971)	$	(7,053)	$	(8,048)

Underlying net assets were used to estimate the fair value of investments. The fair value of notes receivable are based on future discounted cash flows. The fair values of debt were estimated based on quoted market prices or discounted cash flows using current interest rates for debt with similar terms, company rating, and remaining maturity.

Carrying amounts of available-for-sale securities reflect unrealized holding losses of less than $1 million on both December 31, 2010 and 2009. Sales of available-for-sale securities were $225 million for the year ended December 31, 2010, and immaterial for the years ended December 31, 2009 and 2008.

Investment in Conrail

Through a limited liability company, Norfolk Southern and CSX Corporation (CSX) jointly own Conrail Inc. (Conrail), whose primary subsidiary is Consolidated Rail Corporation (CRC). NS has a 58% economic and 50% voting interest in the jointly owned entity, and CSX has the remainder of the economic and voting interests. NS is amortizing the excess of the purchase price over Conrail’s net equity using the principles of purchase accounting, based primarily on the estimated useful lives of Conrail’s depreciable property and equipment, including the related deferred tax effect of the differences in tax accounting bases for such assets, as all of the purchase price at acquisition was allocable to Conrail’s tangible assets and liabilities.

At December 31, 2010, based on the funded status of Conrail’s pension plans, NS increased its proportional investment in Conrail by $9 million. This resulted in income of $8 million recorded to “other comprehensive income (loss)” and a combined federal and state deferred tax liability of $1 million. At December 31, 2009, NS’ year-end adjustment increased its proportional investment in Conrail by $24 million. This resulted in income of $22 million recorded to “other comprehensive income (loss)” and a combined federal and state deferred tax liability of $2 million. At December 31, 2010, the difference between NS’ investment in Conrail and its share of Conrail’s underlying net equity was $545 million. NS’ equity in the earnings of Conrail, net of amortization, included in “Other income – net” was $26 million, $32 million, and $29 million in 2010, 2009, and 2008, respect ively.

K53

CRC owns and operates certain properties (the Shared Assets Areas) for the joint and exclusive benefit of NSR and CSX Transportation, Inc. (CSXT). The costs of operating the Shared Assets Areas are borne by NSR and CSXT based on usage. In addition, NSR and CSXT pay CRC a fee for access to the Shared Assets Areas. “Purchased services and rents” and “Fuel” include expenses for amounts due to CRC for operation of the Shared Assets Areas totaling $118 million in 2010, $123 million in 2009, and $131 million in 2008. Future minimum lease payments due to CRC under the Shared Assets Areas agreements are as follows: $30 million in each of 2011 through 2015 and $257 million thereafter. NS provides certain general and administrative support functions to Conrail, the fees for which are billed in accordance with several service-provider arrangements and approximate $7 million annually.

“Accounts payable” includes $128 million at December 31, 2010, and $104 million at December 31, 2009, due to Conrail for the operation of the Shared Assets Areas. In addition, “Other liabilities” includes $133 million at December 31, 2010 and 2009, for long-term advances from Conrail, maturing 2035, that bear interest at an average rate of 4.4%.

Investment in Pan Am Southern LLC

Pan Am Southern LLC (PAS) is a railroad company joint venture in which NS and Pan Am Railways, Inc. (Pan Am) each has a 50% equity interest. As of December 31, 2010, NS has contributed cash and other property with a combined value of approximately $116 million and committed to contribute an additional $24 million in cash over the next two years. A significant portion of NS’ contributions has and will continue to be used for capital improvements to the PAS lines and the related construction of new intermodal and automotive terminals.

K56

During the third quarter of 2010, NS issued an additional $250 million of 6.00% Senior Notes due 2105.

During the second quarter of 2009, NS issued $500 million of unsecured notes at 5.90% due 2019 pursuant to its automatic shelf registration statement described below. The net proceeds from the offering were approximately $496 million after deducting the purchase discount and expenses.

During the first quarter of 2009, NS issued $500 million of unsecured notes at 5.75% due 2016 in a private offering. The net proceeds from the offering were approximately $494 million after deducting the purchase discount and expenses. During the fourth quarter of 2009, NS exchanged the unregistered securities with essentially identical securities registered under the Securities Act of 1933.

NS has in place a $350 million receivables securitization facility under which NSR sells substantially all of its eligible third-party receivables to an NS subsidiary, which in turn may transfer beneficial interests in the receivables to various commercial paper vehicles. Amounts received under the facility are accounted for as borrowings. Under this facility, NS received and repaid $100 million in 2010. At December 31, 2010 and 2009, respectively, the amounts outstanding under the facility were $200 million at an average variable interest rate of 1.54% and $200 million at an average variable interest rate of 2.22%. NS’ intent is to refinance $100 million of these borrowings on a long-term basis, which is supported by its $1 billion credit agreement (see below). Accordingly, these amounts outstanding are included in the line item “Long-term debt” and the remaining $100 million outstanding at December 31, 2010 and 2009 , respectively, is included in the line item “Short-term debt” in the Consolidated Balance Sheets. The facility has a 364-day term which was renewed and amended in October 2010 to run until October 2011. During 2009, NS reduced the total amount that can be borrowed from $500 million to $350 million to more closely match NS’ liquidity requirements and receivables profile. At December 31, 2010 and 2009, the amounts of receivables included in “Accounts receivable – net” serving as collateral for these borrowings were $647 million and $571 million, respectively.

The equipment obligations and the capitalized leases are secured by liens on the underlying equipment. Certain lease obligations require the maintenance of yen-denominated deposits, which are pledged to the lessor to satisfy yen-denominated lease payments. These deposits are included in “Other assets” in the Consolidated Balance Sheets and totaled $35 million at December 31, 2010, and $47 million at December 31, 2009.

Issuance of Debt or Equity Securities

NS has authority from its Board of Directors to issue an additional $1 billion of debt or equity securities through public or private sale.

Credit Agreement, Debt Covenants, and Commercial Paper

NS has in place and available a $1 billion, five-year credit agreement expiring in 2012, which provides for borrowings at prevailing rates and includes covenants. NS had no amounts outstanding under this facility at December 31, 2010 and 2009, and NS is in compliance with all of the covenants.

NS has the ability to issue commercial paper supported by its $1 billion credit agreement. At December 31, 2010 and 2009, NS had no outstanding commercial paper.

Pension and Other Postretirement Benefit Assumptions

Pension and other postretirement benefit costs are determined based on actuarial valuations that reflect appropriate assumptions as of the measurement date, ordinarily the beginning of each year. The funded status of the plans is determined using appropriate assumptions as of each year end. A summary of the major assumptions follows:

	2010	2009	2008

*Pension funded status:*
Discount rate	5.25%	5.85%	6.25%
Future salary increases	4.5%	4.5%	4.5%
*Other postretirement benefits funded status:*
Discount rate	5.4%	5.85%	6.25%
*Pension cost:*
Discount rate	5.85%	6.25%	6.25%
Return on assets in plans	8.75%	8.75%	9%
Future salary increases	4.5%	4.5%	4.5%
*Other postretirement benefits cost:*
Discount rate	5.85%	6.25%	6.25%
Return on assets in plans	8.5%	8.5%	8.5%

To determine the discount rates, NS utilized analyses in which the projected annual cash flows from the pension and postretirement benefit plans were matched with yield curves based on an appropriate universe of high-quality corporate bonds. NS used the results of the yield curves to select the discount rates that match the payment streams of the benefits in each of these plans.

Health Care Cost Trend Assumptions

For measurement purposes at December 31, 2010, increases in the per capita cost of covered health care benefits were assumed to be 8.5% for 2010 and 8.1% for 2011. It is assumed the rate will decrease gradually to an ultimate rate of 5% for 2019 and remain at that level thereafter.

Assumed health care cost trend rates have a significant effect on the amounts reported in the consolidated financial statements. To illustrate, a one-percentage-point change in the assumed health care cost trend would have the following effects:

Total service and interest cost components	$	11	$	(9)
Postretirement benefit obligation	$	143	$	(118)

Asset Management

Ten investment firms manage NS’ defined benefit pension plan’s assets under investment guidelines approved by the Board of Directors prior to 2011 and, effective for 2011, approved by a management committee. Investments are restricted to domestic fixed income securities, international fixed income securities, domestic and international equity investments, and unleveraged exchange-traded options and financial futures. Limitations restrict investment concentration and use of certain derivative investments. The target asset allocation for equity is 75% of the pension plan’s assets. The fixed income portfolio is invested in the Barclay’s Government/Credit Bond Index Fund, except that the Canadian earmarked portion of the Fund is maintained in U.S. Treasury Bonds. Equity investments must be in liquid securities listed on national exchanges. No investment is permitted in the securities of Norfolk Southern or i ts subsidiaries (except through commingled pension trust funds). Investment managers’ returns are expected to meet or exceed selected market indices by prescribed margins.

K61

NS’ pension plan weighted-average asset allocations, by asset category, were as follows:

	Percentage of plan
	assets at December 31,
	2010	2009

Domestic equity securities	54%	64%
International equity securities	12%	12%
Debt securities	21%	23%
Cash and cash equivalents	13%	1%
Total	100%	100%

The postretirement benefit plan assets consist primarily of trust-owned variable life insurance policies with an asset allocation at December 31, 2010, of 58% in equity securities and 42% in debt securities compared with 57% in equity securities and 43% in debt securities at December 31, 2009. The target asset allocation for equity is between 50% and 75% of the plan’s assets.

The plans’ assumed future returns are based principally on the asset allocations and historic returns for the plans’ asset classes determined from both actual plan returns and, over longer time periods, market returns for those asset classes. The expected long-term rate of return on plan assets is applied to a calculated value of plan assets that recognizes changes in fair value over a three-year period. NS assumed a rate of return on pension plan assets of 8.75% for 2010 and 2009, and 9% for 2008. For 2011, NS assumes an 8.75% return on pension plan assets. A one percentage point change to the rate of return assumption would result in a $16 million change to the net pension cost and, as a result, an equal change in “Compensation and benefits” expense.

Fair Value of Plan Assets

Following is a description of the valuation methodologies used for pension plan assets measured at fair value.

Interest bearing cash:  Short-term bills or notes are valued at an estimated price at which a dealer would pay for the security at year end using observable market based inputs; money market funds are valued at the closing price reported on the active market on which the funds are traded.
United States Government and agencies securities:  Valued at an estimated price at which a dealer would pay for a security at year end using observable as well as unobservable market based inputs.  Inflation adjusted instruments utilize the appropriate index factor.
Municipal bonds:  Valued at an estimated price at which a dealer would pay for a security at year end using observable market based inputs.
Corporate bonds and other fixed income instruments:  When available, valued at an estimated price at which a dealer would pay for a similar security at year end using observable market inputs.  Otherwise, valued at an estimated price at which a dealer would pay for a similar security at year end using unobservable market inputs.
Common stock:  Shares held by the plan at year end are valued at the official closing price as defined by the exchange or at the most recent trade price of a security at the close of the active market.
Commingled funds:  Valued at the net asset value (NAV) of shares held by the plan at year end, based on the quoted market prices of the underlying assets of the funds.  The investments are valued using NAV as a practical expedient for fair value.  The commingled funds hold equity securities.
Preferred stock:   Shares held by the plan at year end are valued at the most recent trade price of a security at the close of the active market or at an estimated price at which a dealer would pay for a similar security at year end using observable as well as unobservable market-based inputs.
Common collective trusts: ��Valued at the NAV of shares held by the plan at year end, based on the quoted market prices of the underlying assets of the trusts.  The investments are valued using NAV as a practical expedient for fair value.  The common collective trusts hold equity securities, fixed income securities and cash and cash equivalents.

Common collective trust investments included debt securities of approximately $361 million and $100 million at December 31, 2010 and 2009, respectively, international equity securities of approximately $160 million and $141 million at December 31, 2010 and 2009, respectively, and domestic equity securities of zero and $144 million at December 31, 2010 and 2009, respectively.

Following is a description of the valuation methodologies used for postretirement benefit plan assets measured at fair value.

Trust-owned life insurance: valued at NS’ share of the net assets of trust-owned life insurance issued by a major insurance company. The underlying investments of that trust consist of a U.S. stock account, and a U.S. bond account, valued based upon the aggregate market values of the underlying investments. The loan asset account is valued at cash surrender value at the time of the loan, plus accrued interest.

The postretirement benefit plan assets consisted of trust-owned life insurance with fair values of $178 million and $161 million at December 31, 2010 and 2009, respectively, and are valued under level 2 of the fair value hierarchy. There were no level 1 or level 3 related assets.

The methods used to value pension and postretirement benefit plan assets may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while NS believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

K63

Contributions and Estimated Future Benefit Payments

In 2011, NS expects to contribute approximately $12 million to its unfunded pension plans for payments to pensioners and $55 million to its other postretirement benefit plans for retiree health benefits. NS does not expect to contribute to its funded pension plan in 2011. In 2010, NS made a voluntary contribution to its funded pension plan of $100 million.

Benefit payments, which reflect expected future service, as appropriate, are expected to be paid as follows:

				Other
		Pension		Postretirement
		Benefits		Benefits
		($ in millions)

2011	$	116	$	55
2012		119		57
2013		122		59
2014		124		61
2015		126		64
Years 2016 - 2020		650		352

The other postretirement benefits payments include an estimated average annual reduction due to the Medicare Part D subsidy of approximately $6 million.

Other Postretirement Coverage

Under collective bargaining agreements, NS and certain subsidiaries participate in a multi-employer benefit plan, which provides certain postretirement health care and life insurance benefits to eligible union employees. Premiums under this plan are expensed as incurred and amounted to $43 million in 2010, and $33 million in both 2009 and 2008.

Section 401(k) Plans

Norfolk Southern and certain subsidiaries provide Section 401(k) savings plans for employees. Under the plans, NS matches a portion of employee contributions, subject to applicable limitations. NS’ matching contributions, recorded as an expense, under these plans were $15 million in 2010, $16 million in 2009, and $15 million in 2008.

12. Stock-Based Compensation

Under the stockholder-approved Long-Term Incentive Plan (LTIP), a committee of nonemployee directors of the Board or the chief executive officer (if delegated such authority by the committee) may grant stock options, stock appreciation rights (SARs), restricted stock units, restricted shares, performance shares, and performance share units (PSUs), up to a maximum of 96,125,000 shares of Norfolk Southern Common Stock (Common Stock). Of these shares, 5,000,000 were approved by the Board for issuance to non-officer participants; as a broad-based issuance, stockholder approval was not required. In May 2010, the stockholders approved an amended LTIP that eliminated the previous limit on the number of shares of stock that could be granted as restricted stock units, restricted shares, or performance shares and instead adopted a fungible share reserve ratio so that, for awards granted after May 13, 2010, the number of shares remaining for issuance under the amended LTIP will be reduced (i) by 1 for each award granted as an option or stock-settled stock appreciation right, or (ii) by 1.61 for an award made in the form other than an option or stock-settled stock appreciation right. Under the Board-approved Thoroughbred Stock Option Plan (TSOP), the committee may grant stock options up to a maximum of 6,000,000 shares of Common Stock; as a broad-based stock option plan, stockholder approval of TSOP was not required. NS uses newly issued shares to satisfy any exercises and awards under LTIP and TSOP.

The LTIP also permits the payment – on a current or a deferred basis and in cash or in stock – of dividend equivalents on shares of Common Stock covered by options, PSUs, or restricted stock units in an amount commensurate with regular quarterly dividends paid on Common Stock.

K64

During the first quarter of 2010, a committee of nonemployee directors of NS’ Board granted stock options, restricted stock units and PSUs pursuant to LTIP and granted stock options pursuant to TSOP. Receipt of an award under LTIP was made contingent upon the awardee’s execution of a non-compete agreement, and all awards under LTIP were made subject to forfeiture in the event the awardee “engages in competing employment” for a period of time following retirement.

Accounting Method

NS accounts for its grants of PSUs, restricted stock units, restricted shares, dividend equivalents, tax absorption payments, and SARs in accordance with ASC 718 “Share-Based Payment.” Accordingly, all awards result in charges to net income while dividend equivalents, which are all related to equity classified awards, are charged to retained income. Related compensation costs were $67 million in 2010, $60 million in 2009, and $89 million in 2008. The total tax effects recognized in income in relation to stock-based compensation were benefits of $21 million in 2010, $18 million in 2009, and $30 million in 2008.

“Common stock issued – net” in the Consolidated Statements of Cash Flows for the years ended December 31, 2010, 2009, and 2008 includes tax benefits generated from tax deductions in excess of compensation costs recognized (excess tax benefits) for share-based awards of $33 million, $15 million, and $76 million, respectively.

Stock Options

Options may be granted for a term not to exceed 10 years and are subject to a vesting period of at least one year. Option exercise prices are at not less than the fair market value of Common Stock on the effective date of the grant and, effective for awards granted after May 13, 2010, may not be less than the higher of (i) the fair market value of Common Stock on the date of grant or (ii) the closing price of Common Stock on the date of grant. In the first quarter of 2010, 824,900 options were granted under the LTIP and 259,800 options were granted under the TSOP. In each case, the grant price was $47.76, which was the higher of (i) the average fair market value of Common Stock on the date of grant or (ii) the closing price of Common Stock on the date of the grant. The options granted under the LTIP and TSOP in 2010 may not be exercised prior to the fourth and third anniversaries of the date of grant, respectively. Holders of the options granted under the LTIP in 2010 who remain actively employed receive cash dividend equivalent payments for four years in an amount equal to the regular quarterly dividends paid on Common Stock.

In the first quarter of 2009, 1,209,700 options were granted under the LTIP and 251,200 options were granted under the TSOP, each with a grant price of $38.71. The options granted under the LTIP and TSOP in 2009 may not be exercised prior to the fourth and third anniversaries of the date of grant, respectively. In the first quarter of 2008, 1,162,600 options were granted under the LTIP and 250,000 options were granted under the TSOP, each with a grant price of $50.74. The options granted under the LTIP and TSOP in 2008 may not be exercised prior to the third anniversary of the date of grant. For both 2009 and 2008, the grant price was the higher of (i) the average fair market value of Common Stock on the date of grant or (ii) the closing price of Common Stock on the date of the grant, and the options have a term of ten years.

K65

The fair value of each option awarded in 2010, 2009, and 2008 was measured on the date of grant using a lattice-based option valuation model. Expected volatilities are based on implied volatilities from traded options on Common Stock and historical volatility of Common Stock. NS uses historical data to estimate option exercises and employee terminations within the valuation model. The average expected option life is derived from the output of the valuation model and represents the period of time that options granted are expected to be outstanding. The average risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. For options granted that include dividend equivalent payments, a dividend yield of zero was used. For 2010, 2009, and 2008, a dividend yield of 2.89%, 2.4%, and 2.29%, respectively, was used for LTIP options for periods where no dividend equivalent payments are made as we ll as for TSOP options which do not receive dividend equivalents. The assumptions for the 2010, 2009, and 2008 LTIP and TSOP grants are shown in the following table:

	2010	2009	2008

Expected volatility range	29% - 32%	28% - 53%	25% - 32%
Average expected volatility	32%	43%	32%
Average risk-free interest rate	3.63%	2.87%	3.68%
Average expected option term LTIP	8.3 years	6.5 years	5.9 years
Per-share grant-date fair value LTIP	$18.54	$18.18	$19.32
Average expected option term TSOP	8.3 years	9.2 years	8.0 years
Per-share grant-date fair value TSOP	$14.91	$15.41	$16.29
Options granted (LTIP and TSOP)	1,084,700	1,460,900	1,412,600

A summary of options and changes during the year is presented below:

Restricted Stock Units and Restricted Shares

Restricted stock unit grants were 168,250 in 2010, with a grant-date fair value of $47.76 and a five-year restriction period. In 2009, restricted stock unit grants were 320,550 with a grant-date fair value of $38.72 and a five-year restriction period. In 2008, restricted stock unit grants were 299,950 with a grant-date fair value of $50.47 and a five-year restriction period. Restricted stock units granted in 2010, 2009, and 2008 will be settled through issuance of shares of Common Stock. The restricted stock unit grants include cash dividend equivalent payments during the restriction period commensurate with regular quarterly dividends paid on Common Stock. No restricted shares were issued during 2010, 2009, or 2008.

A summary of the status of and changes in restricted stock units and restricted shares is presented below:

				Weighted-

Nonvested at December 31, 2010	1,098,000	--	$	40.94

At December 31, 2010, there was $7 million of total unrecognized compensation related to restricted stock units granted under the LTIP, which is expected to be recognized over a weighted-average period of approximately 2.9 years. The total fair values of the restricted stock units paid in cash and restricted shares vested during the twelve months ended December 31, 2010, 2009, and 2008 were $35 million, $26 million, and $1 million, respectively. The total related excess tax amounts realized were: a benefit of $2 million in 2010; a liability of $1 million in 2009; and, a benefit of $1 million in 2008.

Performance Share Units

PSUs provide for awards based on achievement of certain predetermined corporate performance goals (total shareholder return, return on average invested capital and operating ratio) at the end of a three-year cycle. PSU grants and average grant-date fair values were 824,900 and $47.76 in 2010; 1,209,700 and $38.705 in 2009; and 1,162,600 and $50.465 in 2008. The PSUs granted in 2010 and 2009 will be paid in the form of shares of Common Stock; however, one-half of any previously granted PSUs earned will be paid in the form of shares of Common Stock, with the other half to be paid in cash. A summary of the status of and changes in PSUs is presented below:

As of December 31, 2010, there was $10 million of total unrecognized compensation related to PSUs granted under the LTIP, which is expected to be recognized over a weighted-average period of approximately 1.8 years. The total fair values of PSUs earned and paid in cash during the twelve months ended December 31, 2010, 2009, and 2008 were $20 million, $19 million, and $26 million, respectively. The total related excess tax liability realized was less than $1 million in 2010 and $2 million in 2009, and the total related excess tax benefit in 2008 was $2 million.

14. Stock Repurchase Program

In November 2010, NS completed the share repurchase program approved by its Board of Directors in November 2005 (as amended in March 2007), pursuant to which NS repurchased a total of 75 million shares of its Common Stock (the “2005 Program”). On July 27, 2010, NS’ Board of Directors authorized the repurchase of up to an additional 50 million shares of Common Stock through December 31, 2014. The timing and volume of purchases is guided by management’s assessment of market conditions and other pertinent facts. Any near-term share repurchases are expected to be made with internally generated cash or proceeds from borrowings. NS repurchased and retired 14.7 million shares, zero shares, and 19.4 million shares of its Common Stock under this program in 2010, 2009, and 2008, respectively, at a cost of $863 million, zero, and $1.1 billion, respectively. Since inception of the 2005 Program, NS has repurchased and retired 7 9.4 million shares of Common Stock at a total cost of $4.1 billion.

15. Earnings Per Share

The following tables set forth the calculation of basic and diluted earnings per share:

		2010		2009		2008
		($ in millions except per share, shares in millions)

Basic earnings per share:
Income available to common stockholders	$	1,488	$	1,026	$	1,707
Weighted-average shares outstanding		366.5		367.1		372.3
Basic earnings per share	$	4.06	$	2.79	$	4.58

In 2009, NS adopted the provisions of the FASB FSP EITF No. 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities” (ASC 260-10), which requires the treatment of unvested stock options receiving dividend equivalents as participating securities in computing earnings per share under the two-class method. Accordingly, income available to common stockholders for 2010 and 2009, reflects $8 million reductions, and for 2008, reflects a $9 million reduction from net income for the effect of dividend equivalent payments made to holders of stock options.

		2010		2009		2008
		($ in millions except per share, shares in millions)

Diluted earnings per share:
Income available to common stockholders	$	1,488	$	1,026	$	1,716
Weighted-average shares outstanding per above		366.5		367.1		372.3
Diluted effect of outstanding options, PSUs and restricted stock units/shares		5.3		5.0		7.7
Adjusted weighted-average shares outstanding		371.8		372.1		380.0
Diluted earnings per share	$	4.00	$	2.76	$	4.52

As required under the provisions of FSP EITF No. 03-6-1 (ASC 260-10), diluted earnings per share for 2010 and 2009 were calculated under the more dilutive two-class method (as compared to the treasury stock method) and accordingly, income available to common stockholders for 2010 and 2009 reflects $8 million reductions from net income for dividend equivalent payments. The diluted calculations exclude options having exercise prices exceeding the average market price of Common Stock as follows: none in 2010, 1.4 million in 2009, and none in 2008.

16. Derivative Financial Instruments

All derivatives are recognized in the financial statements as either assets or liabilities and are measured at fair value. Changes in fair value are recorded as adjustments to the assets or liabilities being hedged in “Other comprehensive loss,” or in current earnings, depending on whether the derivative is designated and qualifies for hedge accounting, the type of hedge transaction represented, and the effectiveness of the hedge.

NS has used derivative financial instruments to manage its overall exposure to fluctuations in interest rates. NS does not engage in the trading of derivatives. Management has determined that its derivative financial instruments qualify as fair-value hedges, having values that highly correlate with the underlying hedged exposures, and has designated such instruments as hedging transactions. Credit risk related to the derivative financial instruments is considered to be minimal and is managed by requiring high credit standards for counterparties and periodic settlements.

K70

Interest Rate Hedging

NS manages its overall exposure to fluctuations in interest rates by issuing both fixed- and floating-rate debt instruments, and by entering into interest rate hedging transactions to achieve an appropriate mix within its debt portfolio. NS had zero and $4 million, or less than 1%, of its fixed-rate debt portfolio hedged as of December 31, 2010, and 2009, respectively, using interest rate swaps that qualify for and are designated as fair-value hedge transactions. NS’ interest rate hedging activity resulted in decreases in interest expense of less than $1 million for 2010, 2009, and 2008. These swaps have been effective in hedging the changes in fair value of the related debt arising from changes in interest rates and there has been no impact on earnings resulting from ineffectiveness associated with these derivative transactions.

Fair Values

Fair values of interest rate swaps at December 31, 2010, and 2009, were determined based upon the present value of expected future cash flows discounted at the appropriate implied spot rate from the spot rate yield curve. Fair value adjustments are noncash transactions and, accordingly, are excluded from the Consolidated Statements of Cash Flows. The gross and net asset position of NS’ outstanding derivative financial instruments was zero and less than $1 million at December 31, 2010 and 2009, respectively.

17. Commitments and Contingencies

Lawsuits

Norfolk Southern and/or certain subsidiaries are defendants in numerous lawsuits and other claims relating principally to railroad operations. When management concludes that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to earnings. While the ultimate amount of liability incurred in any of these lawsuits and claims is dependent on future developments, in management’s opinion, the recorded liability is adequate to cover the future payment of such liability and claims. However, the final outcome of any of these lawsuits and claims cannot be predicted with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments are known.

Casualty Claims

Casualty claims include employee personal injury and occupational claims as well as third-party claims, all exclusive of legal costs. To aid in valuing its personal injury liability and determining the amount to accrue with respect to such claim during the year, NS’ management utilizes studies prepared by an independent consulting actuarial firm. Job-related accidental injury and occupational claims are subject to the Federal Employers’ Liability Act (FELA), which is applicable only to railroads. FELA’s fault-based system produces results that are unpredictable and inconsistent as compared with a no-fault workers’ compensation system. The variability inherent in this system could result in actual costs being different from the liability recorded. While the ultimate amount of claims incurred is dependent on future developments, in management’s opinion, the recorded liability is adequate to cover the future payments of claims and is supported by the most recent actuarial study. In all cases, NS records a liability when the expected loss for the claim is both probable and estimable.

K71

Employee personal injury claims – The largest component of casualties and other claims expense is employee personal injury costs. The independent actuarial firm engaged by NS provides quarterly studies to aid in valuing its employee personal injury liability and estimating its employee personal injury expense. The actuarial firm studies NS’ historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences. The actuary uses the results of these analyses to estimate the ultimate amount of liability, which includes amounts for incurred but unasserted claims. NS adjusts its liability quarterly based upon management’s assessment and the results of the study. While actuarial studies reflected favorable claims development between 2008 and 2009 (resulting in a decrease of the annual cost related to personal injuries from $78 million to $51 million), a re duced level of favorable development in 2010 resulted in an increase in the annual cost related to personal injuries to $75 million in 2010 from $51 million in 2009. The estimate of loss liabilities is subject to inherent limitation given the difficulty of predicting future events such as jury decisions, court interpretations, or legislative changes and as such the actual loss may vary from the estimated liability recorded.

Occupational claims – Occupational claims (including asbestosis and other respiratory diseases, as well as conditions allegedly related to repetitive motion) are often not caused by a specific accident or event but rather allegedly result from a claimed exposure over time. Many such claims are being asserted by former or retired employees, some of whom have not been employed in the rail industry for decades. The independent actuarial firm provides an estimate of the occupational claims liability based upon NS’ history of claim filings, severity, payments, and other pertinent facts. The liability is dependent upon management’s judgments made as to the specific case reserves as well as judgments of the consulting independent actuarial firm in the periodic studies. The actuarial firm’s estimate of ultimate loss includes a provision for those claims that have been incurred but not reported. This pr ovision is derived by analyzing industry data and projecting NS’ experience into the future as far as can be reasonably determined. NS adjusts its liability quarterly based upon management’s assessment and the results of the study. However, it is possible that the recorded liability may not be adequate to cover the future payment of claims. Adjustments to the recorded liability are reflected in operating expenses in the periods in which such adjustments become known.

Third-party claims – NS records a liability for third-party claims including those for highway crossing accidents, trespasser and other injuries, automobile liability, property damage, and lading damage. The independent actuarial firm assists with the calculation of potential liability for third-party claims, except lading damage, based upon NS’ experience including number and timing of incidents, amount of payments, settlement rates, number of open claims, and legal defenses. The actuarial estimate includes a provision for claims that have been incurred but have not yet been reported. Each quarter NS adjusts its liability based upon management’s assessment and the results of the study. Given the inherent uncertainty in regard to the ultimate outcome of third-party claims, it is possible that the actual loss may differ from the estimated liability recorded.

Environmental Matters

NS is subject to various jurisdictions’ environmental laws and regulations. It is NS’ policy to record a liability where such liability or loss is probable and its amount can estimated reasonably. Claims, if any, against third parties, for recovery of cleanup costs incurred by NS are reflected as receivables (when collection is probable) in the Consolidated Balance Sheets and are not netted against the associated NS liability. Environmental engineers regularly participate in ongoing evaluations of all known sites and in determining any necessary adjustments to liability estimates. NS also has an Environmental Policy Council, composed of senior managers, to oversee and interpret its environmental policy.

K72

NS’ Consolidated Balance Sheets include liabilities for environmental exposures in the amount of $33 million at December 31, 2010, and $32 million at December 31, 2009 (of which $12 million is classified as a current liability at December 31, 2010 and 2009). At December 31, 2010, the liability represents NS’ estimate of the probable cleanup and remediation costs based on available information at 143 known locations compared with 144 locations at December 31, 2009. As of December 31, 2010, 11 sites accounted for $15 million of the liability, and no individual site was considered to be material. NS anticipates that much of this liability will be paid out over five years; however, some costs will be paid out over a longer period.

At 32 locations, one or more Norfolk Southern subsidiaries, usually in conjunction with a number of other parties, have been identified as potentially responsible parties by the Environmental Protection Agency (EPA) or similar state authorities under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, or comparable state statutes, which often impose joint and several liability for cleanup costs.

The risk of incurring environmental liability – for acts and omissions, past, present, and future – is inherent in the railroad business. Some of the commodities in NS’ traffic mix, particularly those classified as hazardous materials, pose special risks that NS and its subsidiaries work diligently to minimize. In addition, several NS subsidiaries own, or have owned, land used as operating property, or which is leased and operated by others, or held for sale. Because environmental problems may exist on these properties that are latent or undisclosed, there can be no assurance that NS will not incur environmental liabilities or costs with respect to one or more of them, the amount and materiality of which cannot be estimated reliably at this time. Moreover, lawsuits and claims involving these and potentially other unidentified environmental sites and matters are likely to arise from time to time. The resulting liabili ties could have a significant effect on financial position, results of operations, or liquidity in a particular year or quarter.

Based on its assessment of the facts and circumstances now know, management believes that it has recorded the probable costs for dealing with those environmental matters of which NS is aware. Further, management believes that it is unlikely that any known matters, either individually or in the aggregate, will have a material adverse effect on NS’ financial position, results of operations, or liquidity.

Insurance

Norfolk Southern obtains on behalf of itself and its subsidiaries insurance for potential losses for third-party liability and first-party property damages. NS is currently self-insured up to $50 million and above $1 billion per occurrence for bodily injury and property damage to third parties and up to $25 million and above $175 million per occurrence for property owned by NS or in NS’ care, custody, or control.

K73

Purchase Commitments

At December 31, 2010, NS had outstanding purchase commitments totaling approximately $956 million for long-term service contracts through 2019 as well as track material, RoadRailer® trailers, and freight cars, in connection with its capital programs through 2011.

Change-In-Control Arrangements

Norfolk Southern has compensation agreements with certain officers and key employees that become operative only upon a change in control of Norfolk Southern, as defined in those agreements. The agreements provide generally for payments based on compensation at the time of a covered individual’s involuntary or other specified termination and for certain other benefits.

Guarantees

In a number of instances, Norfolk Southern and its subsidiaries have agreed to indemnify lenders for additional costs they may bear as a result of certain changes in laws or regulations applicable to their loans. Such changes may include impositions or modifications with respect to taxes, duties, reserves, liquidity, capital adequacy, special deposits, and similar requirements relating to extensions of credit by, deposits with, or the assets of liabilities of such lenders. The nature and timing of changes in laws or regulations applicable to NS’ financings are inherently unpredictable, and therefore NS’ exposure in connection with the foregoing indemnifications cannot be quantified. No liability has been recorded related to these indemnifications. In case of one type of equipment financing, NSR’s Japanese leverage leases, NSR may terminate the leases and ancillary agreements if such a change-in-law indemnity is triggered. Such a termination would require NSR to make early termination payments that would not be expected to have a material effect on NS’ financial position, results of operations, or liquidity.

NS has indemnified parties in a number of transactions for U.S. income tax withholding imposed as a result of changes in U.S. tax law. In all cases, NS has the right to unwind the related transaction if the withholding cannot be avoided in the future. Because these indemnities would be triggered and are dependent upon a change in the tax law, the maximum exposure is not quantifiable. Management does not believe that it is likely that it will be required to make any payments under these indemnities.

As of December 31, 2010, certain Norfolk Southern subsidiaries are contingently liable as guarantors with respect to $7 million of indebtedness, due in 2019, of an entity in which they have an ownership interest, the Terminal Railroad Association of St. Louis. Four other railroads are also jointly and severally liable as guarantors for this indebtedness. No liability has been recorded related to this guaranty.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Norfolk Southern’s Chief Executive Officer and Chief Financial Officer, with the assistance of management, evaluated the effectiveness of NS’ disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of December 31, 2010. Based on such evaluation, such officers have concluded that, as of December 31, 2010, NS’ disclosure controls and procedures were effective to ensure that information required to be disclosed in NS’ reports under the Exchange Act is recorded, processed, summarized, and reported, within the time period specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Internal Control Over Financial Reporting

The management of Norfolk Southern is responsible for establishing and maintaining adequate internal control over financial reporting. Norfolk Southern’s internal control over financial reporting includes those policies and procedures that pertain to its ability to record, process, summarize, and report reliable financial data. Management recognizes that there are inherent limitations in the effectiveness of any internal control over financial reporting, including the possibility of human error and the circumvention or overriding of internal control. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Further, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time.

In order to ensure that Norfolk Southern’s internal control over financial reporting is effective, management regularly assesses such controls and did so most recently for its financial reporting as of December 31, 2010. This assessment was based on criteria for effective internal control over financial reporting set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on our assessment, management has concluded that Norfolk Southern maintained effective internal control over financial reporting as of December 31, 2010.

The Board of Directors, acting through its Audit Committee, is responsible for the oversight of Norfolk Southern’s accounting policies, financial reporting, and internal control. The Audit Committee of the Board of Directors is comprised entirely of outside directors who are independent of management. The independent registered public accounting firm and the internal auditors have full and unlimited access to the Audit Committee, with or without management, to discuss the adequacy of internal control over financial reporting, and any other matters which they believe should be brought to the attention of the Audit Committee.

Norfolk Southern’s management has issued a report of its assessment of internal control over financial reporting, and Norfolk Southern’s independent registered public accounting firm has issued an attestation report on Norfolk Southern’s internal controls over financial reporting as of December 31, 2010. These reports appear in Part II, Item 8 of this report on Form 10-K.

During the fourth quarter of 2010, management has not identified any changes in internal controls over financial reporting that have materially affected, or are reasonably likely to materially effect, NS’ internal control over financial reporting.

Norfolk Southern Corporation Long-Term Incentive Plan (“LTIP”)

Established on June 28, 1983, and approved by stockholders at their Annual Meeting held on May 10, 1984, LTIP was adopted to promote the success of Norfolk Southern by providing an opportunity for non-employee directors, officers, and other key employees to acquire a proprietary interest in the Corporation. On January 23, 2001, the Board of Directors further amended LTIP and approved the issuance of an additional 5,000,000 shares of authorized but unissued Common Stock under LTIP to participants who are not officers of Norfolk Southern. The issuance of these shares was broadly-based, and stockholder approval of these shares was not required. Accordingly, this portion of LTIP is included in the number of securities available for future issuance for plans not approved by stockholders. Also on January 23, 2001, the Board amended LTIP, which amendment was approved by shareholders on May 10, 2001, that included the reservation for issuance of an addition al 30,000,000 shares of authorized but unissued Norfolk Southern Common Stock.

The amended LTIP eliminated the previous limit on the number of shares of stock that could be granted as restricted stock units, restricted shares, or performance shares and instead adopted a fungible share reserve ratio so that, for awards granted after May 13, 2010, the number of shares remaining for issuance under the amended LTIP will be reduced (i) by 1 for each award granted as an option or stock-settled stock appreciation right, or (ii) by 1.61 for an award made in the form other than an option or stock-settled stock appreciation right. Cash payments of restricted units, stock appreciation rights, and performance share units will not be applied against the maximum number of shares issuable under LTIP. Any shares of Common Stock subject to options, performance share units, restricted shares, or restricted stock units which are not issued as Common Stock will again be available for award under LTIP after the expiration or forfeiture of an award.

Non-employee directors, officers, and other key employees residing in the United States or Canada are eligible for selection to receive LTIP awards. Under LTIP, the Compensation Committee (Committee) may grant incentive stock options, nonqualified stock options, stock appreciation rights, restricted shares, restricted stock units, and performance share units. In addition, dividend equivalents may be awarded for options, restricted stock units, and performance share units. The Committee may make awards under LTIP subject to forfeiture under certain circumstances and may establish such other terms and conditions for the awards as provided in LTIP.

For options granted after May 13, 2010, the option price per share will not be less than the higher of (i) 100% of the fair market value of Norfolk Southern’s Common Stock on the date of grant, or (ii) the closing price of Common Stock on the date of the grant. All options are subject to a vesting period of at least one year, and the term of the option will not exceed ten years. LTIP specifically prohibits option repricing without stockholder approval, except for capital adjustments.

K78

Performance share units entitle a recipient to receive performance-based compensation at the end of a three-year performance cycle based on Norfolk Southern’s performance during that three-year period. For the 2011 performance share unit awards, corporate performance will be measured using three equally weighted standards established by the Committee: (1) three-year average return on average capital invested, (2) three-year average operating ratio, and (3) three-year total return to stockholders as compared with the average total return on the publicly traded stocks of North American Class I railroads, using a 20-day average total shareholder return to measure performance. Performance share units may be payable in either shares of Norfolk Southern Common Stock or cash.

Restricted stock units are payable in cash or in shares of Norfolk Southern Corporation Common Stock at the end of a restriction period of not less than 36 months and not more than 60 months. During the restriction period, the holder of the restricted stock units has no beneficial ownership interest in the Norfolk Southern Common Stock represented by the restricted stock units and has no right to vote the shares represented by the units or to receive dividends (except for dividend equivalent rights that may be awarded with respect to the restricted stock units). The Committee at its discretion may waive the restriction period, but settlement of any restricted stock units will occur on the same settlement date as would have applied absent a waiver of restrictions, if no performance goals were imposed.

Norfolk Southern Corporation Thoroughbred Stock Option Plan

The Board adopted the Norfolk Southern Corporation Thoroughbred Stock Option Plan (“TSOP”) on January 26, 1999, to promote the success of Norfolk Southern by providing an opportunity for nonagreement employees to acquire a proprietary interest in Norfolk Southern and thereby to provide an additional incentive to nonagreement employees to devote their maximum efforts and skills to the advancement, betterment, and prosperity of Norfolk Southern and its stockholders. Under the TSOP there were 6,000,000 shares of authorized but unissued Common Stock reserved for issuance. TSOP has not been and is not required to have been approved by stockholders.

Active full-time nonagreement employees residing in the United States or Canada are eligible for selection to receive TSOP awards. Under TSOP, the Committee may grant nonqualified stock options subject to such terms and conditions as provided in TSOP.

The option price will not be less than 100% of the fair market value of Norfolk Southern’s Common Stock on the effective date the options are granted. All options are subject to a vesting period of at least one year, and the term of the option will not exceed ten years. Options awarded in 2010 are subject to a three-year vesting period. TSOP specifically prohibits repricing without stockholder approval, except for capital adjustments.

K79

Norfolk Southern Corporation Directors’ Restricted Stock Plan

The Norfolk Southern Corporation Directors’ Restricted Stock Plan (“Plan”) was adopted on January 1, 1994, and is designed to increase ownership of Norfolk Southern Common Stock by its non-employee directors so as to further align their ownership interest in Norfolk Southern with that of stockholders. The Plan has not been and is not required to have been approved by stockholders. Currently, a maximum of 66,000 shares of Norfolk Southern Common Stock may be granted under the Plan. To make grants eligible to directors, Norfolk Southern purchases, through one or more subsidiary companies, the number of shares required in open-market transactions at prevailing market prices, or makes such grants from Norfolk Southern Common Stock already owned by one or more of Norfolk Southern’s subsidiary companies.

Only non-employee directors who are not and never have been employees of Norfolk Southern are eligible to participate in the Plan. Upon becoming a director, each eligible director receives a one-time grant of 3,000 restricted shares of Norfolk Southern Common Stock. No individual member of the Board exercises discretion concerning the eligibility of any director or the number of shares granted.

The restriction period applicable to restricted shares granted under the Plan begins on the date of the grant and ends on the earlier of the recipient’s death or six months after the recipient ceases to be a director by reason of disability or retirement. During the restriction period, shares may not be sold, pledged, or otherwise encumbered. Directors will forfeit the restricted shares if they cease to serve as a director of Norfolk Southern for reasons other than their disability, retirement, or death.
