CSX Corporation, together with its subsidiaries ("CSX" or the “Company”), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based freight transportation services including traditional rail service, the transport of intermodal containers and trailers, as well as other transportation services such as rail-to-truck transfers and bulk commodity operations. CSX and the rail industry provide customers with access to an expansive and interconnected transportation network that plays a key role in North American commerce and is critical to the long-term economic success and improved global competitiveness of the United States. In addition, freight railroads provide the most economical and environmentally efficient means to transport goods over land.

CSXT is also responsible for the Company's real estate sales, leasing, acquisition and management and development activities. Substantially all of these activities are focused on supporting railroad operations.

The Company is focused on developing and strictly maintaining a scheduled service plan with an emphasis on improving customer service, optimizing assets and increasing employee engagement. When this operating model is executed effectively, the Company competes for an increased share of the U.S. freight market. Further, this model leads to reduced costs and strong free cash flow generation.

During 2022,2023, the Company's services generated $14.9$14.7 billion of revenue and served four primary lines of business: merchandise, intermodal, coal and trucking.

Other revenue accounted for 6%4% of the Company’s total revenue in 2022.2023. This category includes revenue from regional subsidiary railroads and incidental charges, including intermodal storage and equipment usage, demurrage and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.

Most of the Company’s employees provide or support transportation services. The Company had more than 22,50023,000 employees as of December 2022,2023, which includes approximately 17,10017,700 employees that are members of a rail labor union. As of December 2, 2022, all 12 rail unions at CSX that participated in national bargaining were covered by national agreements with the Class I railroads and CSX-specific agreements that will remain in effect through December 31, 2024. InCollective agreements under the face of supply chain disruptionRailway Labor Act do not expire, but continue until amended, and a tight labor market, CSX continuesformal notices to focus on ensuring the hiring pipeline for frontline railroaders is adequate to meet customer needs and has implemented new recruiting and staffing measures.amend these agreements may be served as early as November 1, 2024.

CSX prioritizes workplace safety for employees and is committed to continued improvement through enhanced processes, training, technology, communication, and continuous collaboration with customers and peers across the railroad industry. Training programs and processes are focused on injury and accident prevention as well as emergency preparedness. The attainment of key safety targets is a component of management's annual incentive program. The FRA Personal Injury Frequency Index, a measure of the number of FRA-reportable injuries per 200,000 man-hours, was 0.960.89 in both2023 and 1.01 in 2022, and 2021, remaining flatimproving year over year.

The Compensation and Talent Management Committee of the Board of Directors is charged with oversight of CSX's workforce. The Company is committed to developing a culture that promotes workforce diversity and inclusion and encourages ethical behavior. As of December 31, 2022,2023, approximately 21%23% of CSX's overall workforce and 36%37% of management was diverse, calculated as the percentage of males of color and all females. In 2022,2023, CSX was recognized as a “Best Place to Work for Disability Inclusion” by Disability:IN and the American Association of People with Disabilities for a fourthfifth consecutive year after receiving a top score on their disability equality index. The CSX Code of Ethics serves as a guiding standard for ethical behavior and covers many types of matters, including discrimination and harassment as well as safety. Annually, all management employees are required, and union employees are highly encouraged, to complete ethics training.

A leader in freight rail transportation for nearly 200 years, the Company’s heritage dates back to the early nineteenth century when The Baltimore and Ohio Railroad Company (“B&O”), the nation’s first common carrier, was chartered in 1827. Since that time, the Company has built on this foundation to create a railroad that could safely and reliably service the ever-increasing demands of a growing nation. Since its founding, numerous railroads have combined with the former B&O through merger and consolidation to create what has become CSX. Each of the railroads that combined into the CSX family brought new geographical reach to valuable markets, gateways, cities, ports and transportation corridors.

CSX Corporation was incorporated in 1978 under Virginia law. In 1980, the Company completed the merger of the Chessie System and Seaboard Coast Line Industries into CSX. The merger allowed the Company to connect northern population centers and Appalachian coal fields to growing southeastern markets. Later, the Company’s acquisition of key portions of Conrail, Inc. ("Conrail") allowed CSXT to link the northeast, including New England and the New York metropolitan area, with Chicago and midwestern markets as well as the growing areas in the Southeast already served by CSXT. This current rail network, which now includes the network acquired from Pan Am, allows the Company to directly serve every major market in the eastern United States with safe, dependable, environmentally responsible and fuel efficient freight transportation and intermodal service.

The business environment in which the Company operates is highly competitive. Shippers typically select transportation providers that offer the most compelling combination of service and price. Service requirements, both in terms of transit time and reliability, vary by shipper and commodity. As a result, the Company’s primary competition varies by commodity, geographic location and mode of available transportation and includes other railroads, motor carriers that operate similar routes across its service area and, to a less significant extent, barges, ships and pipelines.

The Company's operations are subject to various federal, state, provincial (Canada) and local laws and regulations generally applicable to businesses operating in the United States and Canada. In the U.S., the railroad operations conducted by the Company's subsidiaries, including CSXT, are subject to the regulatory jurisdiction of the Surface Transportation Board (“STB”), the Federal Railroad Administration (“FRA”), and its sister agency within the U.S. Department of Transportation ("DOT"), the Pipeline and Hazardous Materials Safety Administration (“PHMSA”). Together, FRA and PHMSA have broad jurisdiction over railroad operating standards and practices, including track, freight cars, locomotives and hazardous materials requirements. In addition, the U.S. Environmental Protection Agency (“EPA”) has regulatory authority with respect to matters that impact the Company's properties and operations. 

The Transportation Security Administration (“TSA”), a component of the Department of Homeland Security, has broad authority over railroad operating practices that may have homeland security implications. In Canada, the railroad operations conducted by the Company’s subsidiaries, including CSXT, are subject to the regulatory jurisdiction of the Canadian Transportation Agency.

CSX has included the certifications of its Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”) required by Section 302 of the Sarbanes-Oxley Act of 2002 (“the Act”) as Exhibit 31, as well as Section 906 of the Act as Exhibit 32 to this Form 10-K report.

The risks set forth in the following risk factors could have a material adverse effect on the Company's financial condition, results of operations or liquidity, and could cause those results to differ materially from those expressed or implied in the Company's forward-looking statements. Additional risks and uncertainties not currently known to the Company or that the Company currently does not deem to be material also may materially impact the Company's financial condition, results of operations or liquidity.

Legislation passed by Congress, new regulations issued by federal agencies, or executive orders issued by the President of the United States could significantly affect the revenues, costs, including income taxes, and profitability of the Company's business. In addition, statutes or regulations imposingthat, among other things, impose price constraints or affecting rail-to-rail competition could adversely affect the Company's profitability.

The Company is subject to the jurisdiction of various regulatory agencies, including the STB, FRA, PHMSA, TSA, EPA and other state, provincial, local and federal regulatory agencies for a variety of economic, health, safety, labor, environmental, tax, legal, cybersecurity and other matters. New or modified rules or regulations by these agencies could increase the Company's operating costs, adversely impact revenue or reduce operating efficiencies and affect service performance. Noncompliance with applicable laws or regulations could erode public confidence in the Company and can subject the Company to fines, penalties and other legal or regulatory sanctions.

CSXT is also required to comply with regulations regarding the handling of hazardous materials. In November 2008,materials and has a legal obligation to transport certain hazardous materials under the common carrier mandate. Applicable rules issued by the TSA issued final rules placingplace significant new security and safety requirements on passenger and freight railroad carriers, rail transit systems and facilities that ship hazardous materials by rail. Noncompliance with these rules can subject the Company to significant penalties and could be a factor in litigation arising out of a train accident. Finally, legislation preventing the transport of hazardous materials through certain cities could result in network congestion and increase the length of haul for hazardous substances, which could increase operating costs, reduce operating efficiency or increase the risk of an accident involving the transport of hazardous materials.

As part of its railroad and other operations, the Company is subject to various claims and lawsuits related to disputes over commercial practices, labor and unemployment matters, occupational and personal injury claims, property damage or freight damage, environmental and other matters. The Company may experience material judgments or incur significant costs to defend existing and future lawsuits. Although the Company maintains insurance to cover some of these types of claims and establishes reserves when appropriate, final amounts determined to be due on any outstanding matters may exceed the Company's insurance coverage or differ materially from the recorded reserves. Additionally, the Company could be impacted by adverse developments not currently reflected in the Company's reserve estimates.

The Company could be materially and adversely affected by a public health crisis, including a widespread epidemic or pandemic. During a health crisis, policies and initiatives may be instituted by the public and private sector to reduce transmission, such as closures of businesses and manufacturing facilities, the promotion of social distancing, the adoption of working from home by companies and institutions, and travel restrictions. These policies or initiatives could adversely affect demand for the commodities and products that the Company transports, including import and export volume.

In addition, initiatives to reduce transmission could result in supply chain disruptions, which could impact volumes and make it more difficult for the Company to serve its customers. Moreover, operations are negatively affected when a significant number of employees are quarantined as the result of exposure to a contagious illness. To the extent a public health crisis adversely affects the Company's business and financial results, it may also have the effect of heightening many of the other risks described herein.

The Company relies on information technology in all aspects of its business. The security, stability and availability of the Company’s and its key third-party vendors’ information technology systems are critical to its ability to operate safely and effectively and to compete within the transportation industry. A successful data breach, cyber-attack, or the occurrence of any similar incident that impacts the Company’s or its key third-party vendors’ information technology systems could result in a service interruption, train accident, misappropriation of confidential or proprietary information (including personal information), process failure, or other operational difficulties. A disruption or compromise of the Company’s or its key third-party vendors' information technology systems, even for short periods of time, and any resulting theft or compromise of Company confidential or proprietary information (including personal information), could adversely affect the Company’s business or reputation, create significant legal, regulatory or financial exposure and have a material adverse impact on CSX’s business, financial condition or operations.

The Company, its third-party vendors and other companies in the rail and transportation industries have been subject to, and are likely to continue to be the target of, data breaches, cyber-attacks and other similar incidents. These incidents may include, among other things, malware, ransomware, distributed denial of service attacks, social engineering, phishing, theft, malfeasance or improper access by employees or third-party vendors, software bugs, server malfunctions, software or hardware failures, human error, fraud, or other modes of attack or disruption. Attacks of these nature are increasing in frequency, levels of persistence, intensity and sophistication.sophistication, including by nation-state threat actors or those associated with nation-states. Further, the Company may be at increased risk of experiencing a cyber-attack as a result of being a component of the critical U.S. infrastructure. If such an event takes place, the Company may be required to incur significant expenses in excess of existing cybersecurity insurance coverage. As cybersecurity threats continue to evolve, the Company may be required to expend significant additional resources to continue to modify or enhance its protective measures or to investigate and remediate any information security vulnerabilities, data breaches, cyber-attacks or other similar incidents. A public health crisis could also increase the risk that theThe Company or its third-party vendors may also experience cybersecurity incidents as a result of employees, third-party vendors and other third parties with which they interact working remotely on less secure systems and environments.

Despite the Company’s efforts to protect its information technology systems, it may not be able to prevent or anticipate all data breaches, cyber-attacks or other similar incidents, detect or react to such incidents in a timely manner or adequately remediate any such incident. While CSX’s security protocols have detected attempts to gain unauthorized access to the Company’s information technology systems, none of such attempts have resulted in any material breach of or disruption to the Company’s systems. For example, CSX has experienced distributed denial of service attacks that have resulted in brief system disruptions, but none have resulted in access to CSX systems. Additionally, despite routine security assessment of the Company’s key third-party vendors, some vendors have experienced cyber-attacks in the past, but none of such attacks have had a material adverse impact on CSX’s business or operations. Due to applicable laws, rules and regulations or contractual obligations, CSX may be held responsible for data breaches, cyber-attacks or other similar incidents attributed to its third-party vendors as they relate to the information CSX shares with them.

Additionally, if CSX is unable to successfully acquire, develop or implement new technology, including artificial intelligence, it may suffer a competitive disadvantage within the rail industry and with companies providing other modes of transportation service.services.

CSXT could experience rail network difficulties related to: (i) locomotive or crew shortages; (ii) labor shortages or other service disruptions in the supply chain affecting trucking, ports, handling facilities, customer facilities or other railroads; (iii) unpredictable increases in demand; (iv) extreme weather conditions; (v) regulatory changes resulting in forced access or impacting where and how fast CSXT can transport freight or maintain routes; (vi) reductions in availability of pooled equipment, including chassis; (vii) impacts from changes in network capacity or structure; or (viii) increased passenger activities, which could impact CSXT's operational fluidity, leading to deterioration of service, asset utilization and overall efficiency.

Terrorist attacks, along with any government response to those attacks, may adversely affect the Company's financial condition, results of operations or liquidity. CSXT's rail lines, other key infrastructure and information technology systems may be targets or indirect casualties of acts of terror or war. This risk could cause significant business interruption and result in increased costs and liabilities and decreased revenues. In addition, premiums charged for some or all of the insurance coverage currently maintained by the Company could increase dramatically, or the coverage may no longer be available.

Furthermore, in response to the heightened risk of terrorism, federal, state and local governmental bodies are proposing and, in some cases, have adopted legislation and regulations relating to security issues that impact the transportation industry. For example, the Department of Homeland Security adopted regulations that require freight railroads to implement additional security protocols when transporting hazardous materials. Complying with these or future regulations could continue to increase the Company's operating costs and reduce operating efficiencies.

The Company's operations may be affected by external factors such as severe weather and other natural occurrences, including floods, hurricanes, fires and earthquakes. As a result, the Company's rail network may be damaged, its workforce may be unavailable, fuel costs may rise and significant business interruptions could occur. In addition, the performance of locomotives and railcars could be adversely affected by extreme weather conditions. Hurricanes as well as storm and flooding events have impacted the Company's network in the past, leading to interrupted service and damage to track and equipment. Changes in weather patterns caused by climate change are expected to increase the frequency, severity or duration of certain adverse weather conditions.

Insurance maintained by the Company to protect against loss of business and other related consequences resulting from these natural occurrences is subject to coverage limitations, depending on the nature of the risk insured. This insurance may not be sufficient to cover all of the Company's damages or damages to others, and this insurance may not continue to be available at commercially reasonable rates. Even with insurance, if any natural occurrence leads to a catastrophic interruption of service, the Company may not be able to restore service without a significant interruption in operations.

The Company experiences competition in pricing, service, reliability and other factors from various transportation providers including railroads and motor carriers that operate similar routes across its service area and, to a less significant extent, barges, ships and pipelines. Other transportation providers generally use public rights-of-way that are built and maintained by governmental entities, while CSXT and other railroads must build and maintain rail networks largely using internal resources. Any future improvements or expenditures materially increasing the quality or reducing the cost of alternative modes of transportation such as through the use of automation, autonomy or electrification, or legislation providing for less stringent size or weight restrictions on trucks, could negatively impact the Company's competitive position. Additionally, any future consolidation in the rail industry could materially affect the regulatory and competitive environment in which the Company operates.

A decline or disruption in general domestic and global economic conditions that affects demand for the commodities and products the Company transports, including import and export volume, could reduce revenues or have other adverse effects on the Company's cost structure and profitability. For example, slower rates of economic growth in Asia, contraction of European economies, and changes in the global supply of seaborne coal or price of seaborne coal have adverse impacts on U.S. export coal volume and result in lower coal revenue for CSX. Additionally, embargoes or changes to trade agreements or policies could result in reduced import and export volumes due to increased tariffs and lower consumer demand. If the Company experiences significant declines in demand for its transportation services with respect to one or more commodities and products or continues to experience the impacts of inflation, the Company may experience reduced revenue and increased operating costs, workforce adjustments, and other related activities, which could have a material adverse effect on the Company's financial condition, results of operations and liquidity.

Over time, changing dynamics in the U.S. and global energy markets, including the impacts of regulation and alternative fuel sources, have resulted in lower energy production from coal-fired power plants in CSX's service territory. Changes in natural gas prices, or other factors impacting demand for electricity, could impact future power generation at coal-fired plants, which would affect the Company's domestic coal volumes and revenues.

The Company regularly relies on capital markets for the issuance of long-term debt instruments, commercial paper and bank financing from time to time. Instability or disruptions of the capital markets, including credit markets, significant increases in interest rates, or the deterioration of the Company’s financial condition due to internal or external factors, could restrict or prohibit access and could increase financing costs. A significant deterioration of the Company’s financial condition could also reduce credit ratings and could limit or affect its access to external sources of capital and increase the costs of short and long-term debt financing.

Marketplace conditions for resources like locomotives as well as the availability of qualified personnel, particularlyincluding engineers and conductors as well as other skilled professional or technical employees, could each have a negative impact on the Company’s ability to meet demand for rail service. Although the Company strives to maintain adequate resources and personnel for the current business environment, unpredictable increases in demand for rail services or extreme weather conditions may exacerbate such risks, which could have a negative impact on the Company’s operational efficiency and otherwise have a material adverse effect on the Company’s financial condition, results of operations, or liquidity in a particular period.

The capital intensive and unique nature of core rail equipment (including rail, ties, freight cars and locomotives) limits the number of railroad equipment suppliers. If any of the current manufacturers stops production or experiences a supply shortage, CSXT could experience a significant cost increase or material shortage. In addition, a few critical railroad suppliers are foreign and, as such, adverse developments in international relations, new trade regulations, disruptions in international shipping or increases in global demand could make procurement of these supplies more difficult or increase CSXT's costs. Additionally, if a fuel supply shortage were to arise, the Company would be negatively impacted.

Most of CSX's employees are represented by labor unions and are covered by collective bargaining agreements. These agreements are either bargained for nationally by the National Carriers Conference Committee or locally between CSX and the union. Such agreements are negotiated over the course of several years and previously have not resulted in any extended work stoppages. Under the Railway Labor Act's procedures (which include mediation, cooling-off periods and the possibility of an intervention by the President of the United States), during negotiations neither party may take action until the procedures are exhausted. If, however, CSX is unable to negotiate acceptable agreements, the employees covered by the Railway Labor Act could strike, which could result in loss of business and increased operating costs as a result of higher wages or benefits paid to union members. 

There is potential for operational impacts from changing weather patterns or rising sea levels in the Company's operational territory, which could impact the Company's network or other assets.

Climate change and other emissions-related laws and regulations have been proposed and, in some cases adopted, on the federal, state, provincial and local levels. These final and proposed laws and regulations take the form of restrictions, caps, taxes or other controls on emissions.emissions as well as requirements to disclose information relating to climate change. In particular, the EPA has issued various regulations and may issue additional regulations targeting emissions, including rules and standards governing emissions from certain stationary sources and from vehicles. Any of these pending or proposed laws or regulations, including any proposed or implemented under the Biden administration, could adversely affect the Company's operations and financial results by, among other things: (i) reducing coal-fired electricity generation due to mandated emission standards; (ii) reducing the consumption of coal as a viable energy resource in the United States and Canada; (iii) increasing the Company's fuel, capital and other operating costs and negatively affecting operating and fuel efficiencies; and (iv) making it difficult for the Company's customers in the U.S. and Canada to produce products in a cost competitive manner. Any of these factors could reduce the amount of shipments the Company handles and have a material adverse effect on the Company's financial condition, results of operations or liquidity. In addition, CSX may become subject to legal requirements to disclose climate change related information and may become subject to demands or expectations by its supply chain partners, customers or other stakeholders to disclose information relating to climate risk or set related targets or goals. The Company's current practices with respect to climate risk disclosure may fail to meet these developing legal requirements or stakeholder demands or expectations. In addition, legislative or regulatory uncertainties and change regarding climate-related risks, including inconsistent perspectives or requirements, are likely to result in higher regulatory, compliance, credit, reputational and other risks and costs.

The Company is subject to wide-ranging federal, state, provincial and local environmental laws and regulations concerning, among other things, emissions into the air, ground and water; the handling, storage, use, generation, transportation and disposal of waste and other materials; the clean-up of hazardous material and petroleum releases and the health and safety of our employees. If the Company violates or fails to comply with these laws and regulations, CSX could be fined or otherwise sanctioned by regulators. The Company can also be held liable for consequences arising out of human exposure to any hazardous substances for which CSX is responsible. In certain circumstances, environmental liability can extend to formerly owned or operated properties, leased properties, adjacent properties and properties owned by third parties or Company predecessors, as well as to properties currently owned, leased or used by the Company.

The Company has been, and may in the future be, subject to allegations or findings to the effect that it has violated, or is strictly liable under, environmental laws or regulations, and such violations can result in the Company's incurring fines, penalties or costs relating to the cleanup of environmental contamination. Although the Company believes it has appropriately recorded current and long-term liabilities for known and reasonably estimable future environmental costs, it could incur significant costs that exceed reserves or require unanticipated cash expenditures as a result of any of the foregoing. The Company also may be required to incur significant expenses to investigate and remediate known, unknown or future environmental contamination.

The Company’s properties primarily consist of track and its related infrastructure, locomotives, and freight cars and equipment. These categories and the geography of the network are described below.

Serving 26 states, the District of Columbia, and the Canadian provinces of Ontario and Quebec, the CSXT rail network serves, among other markets, New York, Philadelphia and Boston in the Northeast and Mid-Atlantic, the southeast markets of Atlanta, Miami and New Orleans, and the midwestern markets of St. Louis, MemphisColumbus and Chicago.

CSXT’s track structure includes mainline track, connecting terminals and yards, track within terminals and switching yards, sidings used for passing trains, track connecting CSXT's track to customer locations and turnouts that divert trains from one track to another. Total track miles, which reflect the size of CSXT’s network that connects markets, customers and western railroads, are greater than CSXT’s approximately 20,000 route miles. At December 2022,2023, the breakdown of track miles was as follows:

In addition to its physical track structure, the Company operates numerous yards and terminals for rail and intermodal service. These serve as points of connectivity between the Company and its local customers and as sorting facilities where railcars and intermodal containers are received, classed for destination and placed onto outbound trains, or arrive and are delivered to the customer. The Company’s largest yards and terminals based on 20222023 volume (number of railcars or intermodal containers processed) are listed below.

CSXT’s operations are primarily focused on four major transportation networks and corridors that are defined geographically and by commodity flows below.

See the following page for a map of the CSX Rail Network. Also included on the map, "CSX Operating Agreement" indicates areas within which CSX can operate through trackage rights beyond the CSX network.

As of December 2022,2023, CSXT owns or long-term leases more than 3,6003,500 locomotives. From time to time, the Company also short-term leases locomotives based on business needs. Freight locomotives are used primarily to pull trains while switching locomotives are used in yards. Auxiliary units are typically used to provide extra traction for heavy trains in hilly terrain. Of owned locomotives, approximately 68% were in active service as of December 31, 2022,2023, and the remainder were in storage to be utilized as needed. Storing locomotives and equipment allows the Company to quickly adjust its active fleet based on demand and other factors while avoiding delays due to supply limitations or excessive lead times to acquire additional equipment. As of December 2022,2023, CSXT’s fleet of owned or long-term leased locomotives consisted of the following types:

The Company owns or long-term leases rail equipment, including several types of freight cars and intermodal containers. Of total owned and long-term leased equipment, approximately 91%89% was in active service as of December 31, 2022,2023, and the remainder were in storage to be utilized as needed. As of December 2022,2023, the Company’s owned and long-term leased equipment consisted of the following:

At any time, approximately two-thirds of the railcars on the CSXT system are not owned or leased by the Company. Examples of these include railcars owned by other railroads (which are utilized by CSXT), shipper-furnished or private cars (which are generally used only in that shipper’s service), multi-level railcars used to transport automobiles (which are shared between railroads) and double-stack railcars, or well cars (which are industry pooled), that allow for two intermodal containers to be loaded one above the other.

Executive officers of the Company are elected by the CSX Board of Directors and generally hold office until the next annual election of officers. There are no family relationships or any arrangement or understanding between any officer and any other person pursuant to which such officer was elected. As of the date of this filing, the executive officers’ names, ages and business experience are:

CSX’s common stock is listed on the Nasdaq Global Select Market, which is its principal trading market, and is traded over-the-counter and on exchanges nationwide. The official trading symbol is “CSX.”

CSX reports its financial results in accordance with United States generally accepted accounting principles ("GAAP"). CSX also uses certain non-GAAP measures that fall within the meaning of Securities and Exchange Commission Regulation G and Regulation S-K Item 10(e), which may provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP measures do not have standardized definitions and are not defined by GAAP. Therefore, CSX’s non-GAAP measures are unlikely to be comparable to similar measures presented by other companies. The presentation of these non-GAAP measures should not be considered in isolation from, as a substitute for, or as superior to the financial information presented in accordance with GAAP. Reconciliations of non-GAAP measures to corresponding GAAP measures are below.

Management believes that free cash flow is useful to investors as it is important in evaluating the Company’s financial performance. More specifically, free cash flow measures cash generated by the business after reinvestment. This measure represents cash available for both equity and bond investors to be used for dividends, share repurchases or principal reduction on outstanding debt. Free cash flow is calculated by using net cash from operations and adjusting for property additions and proceeds from property dispositions. This measure should be considered in addition to, rather than a substitute for, cash provided by operating activities. Free cash flow before dividends decreased $101$412 million year-over-year to $3.7$3.3 billion primarily due to higher property additions and lower proceeds and advances from property dispositions, mostly attributable to the sale of property rights to the Commonwealth of Virginia. These decreasesVirginia in the prior year, as well as higher property additions and less cash from operating activities. Cash from operating activities includes lower cash-generating net earnings and the impact of $168 million of higher payments for retroactive wages and bonuses, and associated taxes, related to finalized labor agreements as well as the offsetting impact of $381 million of postponed federal estimated tax payments, which were partially offsetextended until first quarter 2024 under an Internal Revenue Service tax relief announcement for those impacted by higher net cash provided by operating activities.Hurricane Idalia.

The following table reconciles cash provided by operating activities (GAAP measure) to free cash flow (non-GAAP measure).

Certain operating statistics are estimated and can continue to be updated as actuals settle. The methodology for calculating train velocity, dwell, cars online and trip plan performance differs from that used by the Surface Transportation Board. The Company will continue to report these metrics to the Surface Transportation Board using the prescribed methodology.

The Company is committed to continuous improvement in safety and service performance through training, innovation and investment. Training and safety programs are designed to prevent incidents that can adversely impact employees, customers and communities. Technological innovations that can detect and avoid many types of human factor incidents are designed to serve as an additional layer of protection for the Company's employees. Continued capital investment in the Company's assets, including track, bridges, signals, equipment and detection technology also supports safety performance.

The Company remains focused on safety, service, and controlling costs. Train velocity declined 10%Velocity and dwell improved 12% and 17%, respectively, relative to 2021. Dwell increased by 6% and cars online increased 5% in 2022. ComparedCarload trip plan performance improved to 2021,84% compared to 64% while intermodal trip plan performance improved 3%to 95% compared to 90%, while carload trip plan performance decreased 7%.relative to 2022. CSX has seen an improvement in service metrics in the last quarter of 2022 and expects that trend to continue inthroughout 2023.
