	Accounting Policies, Interim Financial Statements and Basis of Presentation
	In the opinion of the management of KCS, the accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair presentation of the results for interim periods. All adjustments made were of a normal and recurring nature. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. The results of operations for the three months ended March 31, 2014, are not necessarily indicative of the results to be expected for the full year ending December 31, 2014.
	Effective January 1, 2014, the Company adopted, on a prospective basis, the new guidance issued by the Financial Accounting Standards Board (FASB) related to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance requires, unless certain conditions exists, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, similar tax loss, or a tax credit carryforward. If a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

Earnings Per Share Data	'
	Earnings Per Share Data
	Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share adjusts basic earnings per common share for the effects of potentially dilutive common shares, if the effect is not anti-dilutive. Potentially dilutive common shares include the dilutive effects of shares issuable under the Stock Option and Performance Award Plans.
	The following table reconciles the basic earnings per share computation to the diluted earnings per share computation (in millions, except share and per share amounts):

	Lease Conversion Program
	During the fourth quarter of 2013, the Company initiated a multi-year lease conversion program (the “Lease Conversion Program”) to optimize the Company’s capital structure and take advantage of a favorable interest rate environment. This initiative has been funded with a portion of the proceeds from the senior notes issued during the fourth quarter of 2013 and available cash. As part of the Lease Conversion Program, in the first quarter of 2014, the Company purchased $126.6 million of equipment under existing operating leases and replacement equipment as certain operating leases expired. In the first quarter of 2014, the Company recognized $29.9 million of lease termination costs (included in operating expenses) due to the early termination of certain operating leases and the related purchase of the equipment under the Lease Conversion Program.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	Assets and liabilities recognized at fair value are required to be classified into a three-level hierarchy. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value in its entirety requires judgment and considers factors specific to the asset or liability.
	The Company’s derivative financial instruments are measured at fair value on a recurring basis and consist of foreign currency forward contracts, which are classified as Level 2 instruments. The Company determines the fair value of its derivative financial instrument positions based upon pricing models using inputs observed from actively quoted markets and also takes into consideration the contract terms as well as other inputs, including market currency exchange rates. The fair value of the foreign currency forward contract assets was $3.2 million as of March 31, 2014. There were no outstanding foreign currency forward contracts as of December 31, 2013.
	The Company’s short-term financial instruments include cash and cash equivalents, accounts receivable, accounts payable and commercial paper obligations. The carrying value of the short-term financial instruments approximates their fair value.
	The fair value of the Company’s debt is estimated using quoted market prices when available. When quoted market prices are not available, fair value is estimated based on current market interest rates for debt with similar maturities and credit quality. The fair value of the Company’s debt was $1,814.8 million and $2,082.9 million at March 31, 2014 and December 31, 2013, respectively. The carrying value was $1,882.2 million and $2,188.9 million at March 31, 2014 and December 31, 2013, respectively. If the Company’s debt were measured at fair value, the fair value measurements of the individual debt instruments would have been classified as either Level 1 or Level 2 in the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Instruments	'
	Derivative Instruments
	The Company enters into derivative transactions in certain situations based on management’s assessment of current market conditions and perceived risks. Management intends to respond to evolving business and market conditions and in doing so, may enter into such transactions as deemed appropriate.
	Credit Risk. As a result of the use of derivative instruments, the Company is exposed to counterparty credit risk. The Company manages this risk by limiting its counterparties to large financial institutions which meet the Company’s credit rating standards and have an established banking relationship with the Company. As of March 31, 2014, the Company did not expect any losses as a result of default of its counterparties.
	Foreign Currency Forward Contracts. The Company’s Mexican subsidiaries have net U.S. dollar-denominated liabilities (primarily debt) which, for Mexican income tax purposes, are subject to periodic revaluation based on changes in the value of the Mexican peso against the U.S. dollar. This revaluation creates fluctuations in the Company’s Mexican income tax expense and the amount of income taxes paid in Mexico. The Company enters into foreign currency forward contracts to hedge its exposure to this risk. In the first quarter of 2014, the Company entered into foreign currency forward contracts with an aggregate notional amount of $345.0 million. These contracts mature on December 31, 2014, and obligate the Company to purchase a total of Ps.4,642.5 million at a weighted average exchange rate of Ps.13.46 to each U.S. dollar. In the first quarter of 2013, the Company entered into foreign currency forward contracts with an aggregate notional amount of $250.0 million maturing on December 31, 2013. These contracts obligated the Company to purchase a total of Ps.3,275.3 million at a weighted average exchange rate of Ps.13.10 to each U.S. dollar. The Company has not designated any of the foreign currency forward contracts as hedging instruments for accounting purposes. The Company measures the foreign currency forward contracts at fair value each period and recognizes any change in fair value in foreign exchange gain (loss) within the consolidated statements of income.
	The following table presents the fair value of derivative instruments included in the consolidated balance sheets (in millions):

	KCSR Credit Agreement Amendment. On January 30, 2014, the Company and KCSR entered into agreements to establish a $450.0 million commercial paper program for KCSR (the “KCSR Commercial Paper Program”). Also on January 30, 2014, the Company, KCSR and certain other subsidiaries of the Company that guaranty the 2012 KCSR Credit Agreement entered into an amendment to the 2012 KCSR Credit Agreement which eliminated certain representations as a condition to borrowing under the revolving credit facility (the “KCSR Revolving Facility”), provided for the prepayment of all outstanding term loans (the “Term Loan”) under the 2012 KCSR Credit Agreement on or before February 13, 2014, and increased the borrowing capacity under the KCSR Revolving Facility to $450.0 million. The KCSR Revolving Facility serves as a backstop for the KCSR Commercial Paper Program, which now serves as KCSR’s primary means of short-term funding.
	KCSM Credit Agreement Amendment. On January 30, 2014, KCSM entered into agreements to establish a $200.0 million commercial paper program for KCSM (the “KCSM Commercial Paper Program”). Also on January 30, 2014, KCSM and certain subsidiaries of KCSM that guaranty the 2012 KCSM Credit Agreement entered into an amendment to the 2012 KCSM Credit Agreement which eliminated certain representations as a condition to borrowing under the KCSM revolving credit facility (the “KCSM Revolving Facility”) and provided for same-day availability of borrowed funds if desired by KCSM. The KCSM Revolving Facility serves as a backstop for the KCSM Commercial Paper Program, which now serves as KCSM’s primary means of short-term funding.
	KCSM 8.0% Senior Notes. On February 3, 2014, KCSM redeemed all of the remaining $62.8 million aggregate principal amount of the KCSM 8.0% senior unsecured notes due February 1, 2018, at a redemption price (expressed as a percentage of the principal amount) of 104.0%, using a portion of the proceeds from the KCSM floating rate senior unsecured notes due October 28, 2016, issued in the fourth quarter of 2013.
	KCSR Revolving Credit Facility and Term Loan. On February 7, 2014, KCSR borrowed $175.0 million under the KCSR Revolving Facility and used the proceeds and cash on hand to repay the outstanding $245.3 million principal amount of the KCSR Term Loan. On February 14, 2014, KCSR repaid the outstanding $175.0 million principal amount of the KCSR Revolving Facility using proceeds received under the KCSR Commercial Paper Program.

Commitments and Contingencies	'
	Commitments and Contingencies
	Concession Duty. Under KCSM’s 50-year railroad concession from the Mexican government (the “Concession”), which would expire in 2047 unless extended, KCSM pays concession duty expense of 1.25% of gross revenues. For the three months ended March 31, 2014, the concession duty expense, which is recorded within materials and other in operating expenses, was $3.6 million, compared to $3.4 million for the same period in 2013.
	Litigation. The Company is a party to various legal proceedings and administrative actions, all of which, except as set forth below, are of an ordinary, routine nature and incidental to its operations. Included in these proceedings are various tort claims brought by current and former employees for job-related injuries and by third parties for injuries related to railroad operations. KCS aggressively defends these matters and has established liability provisions, which management believes are adequate to cover expected costs. Although it is not possible to predict the outcome of any legal proceeding, in the opinion of management, other than those proceedings described in detail below, such proceedings and actions should not, individually, or in the aggregate, have a material adverse effect on the Company’s consolidated financial statements.
	Environmental Liabilities. The Company’s U.S. operations are subject to extensive federal, state and local environmental laws and regulations. The major U.S. environmental laws to which the Company is subject include, among others, the Federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA,” also known as the Superfund law), the Toxic Substances Control Act, the Federal Water Pollution Control Act, and the Hazardous Materials Transportation Act. CERCLA can impose joint and several liabilities for cleanup and investigation costs, without regard to fault or legality of the original conduct, on current and predecessor owners and operators of a site, as well as those who generate, or arrange for the disposal of, hazardous substances. The Company does not believe that compliance with the requirements imposed by the environmental legislation will impair its competitive capability or result in any material additional capital expenditures, operating or maintenance costs. The Company is, however, subject to environmental remediation requirements as described in the following paragraphs.
	The Company’s Mexico operations are subject to Mexican federal and state laws and regulations relating to the protection of the environment through the establishment of standards for water discharge, water supply, emissions, noise pollution, hazardous substances and transportation and handling of hazardous and solid waste. The Mexican government may bring administrative and criminal proceedings, impose economic sanctions against companies that violate environmental laws, and temporarily or even permanently close non-complying facilities.
	The risk of incurring environmental liability is inherent in the railroad industry. As part of serving the petroleum and chemicals industry, the Company transports hazardous materials and has a professional team available to respond to and mitigate environmental issues that might occur in the transport of such materials.
	The Company performs ongoing reviews and evaluations of the various environmental programs and issues within the Company’s operations, and, as necessary, takes actions intended to limit the Company’s exposure to potential liability. Although these costs cannot be predicted with certainty, management believes that the ultimate outcome of identified matters will not have a material adverse effect on the Company’s consolidated financial statements.
	Personal Injury. The Company’s personal injury liability is based on semi-annual actuarial studies performed on an undiscounted basis by an independent third party actuarial firm and reviewed by management. This liability is based on personal injury claims filed and an estimate of claims incurred but not yet reported. Actual results may vary from estimates due to the number, type and severity of the injury, costs of medical treatments and uncertainties in litigation. Adjustments to the liability are reflected within operating expenses in the period in which changes to estimates are known. Personal injury claims in excess of self-insurance levels are insured up to certain coverage amounts, depending on the type of claim and year of occurrence. The personal injury liability as of March 31, 2014, was based on an updated actuarial study of personal injury claims through November 30, 2013, and review of the last four months’ claims experience.
	The personal injury liability activity was as follows (in millions):

	Certain Disputes with Ferromex. KCSM and Ferrocarril Mexicano, S.A. de C.V. (“Ferromex”) use certain trackage rights, haulage rights and interline services (the “Services”) provided by each other. The rates to be charged after January 1, 2009, were agreed to pursuant to the Trackage Rights Agreement, dated February 9, 2010 (the “Trackage Rights Agreement”), between KCSM and Ferromex. The rates payable for these Services for the period beginning in 1998 through December 31, 2008, are still not resolved. KCSM is currently involved in discussions with Ferromex regarding the amounts payable to each other for the Services for this period. If KCSM cannot reach an agreement with Ferromex for rates applicable for Services which were provided prior to January 1, 2009, which are not subject to the Trackage Rights Agreement, the Mexican Secretaría de Comunicaciones y Transportes (“Secretary of Communications and Transportation” or “SCT”) is entitled to set the rates in accordance with Mexican law and regulations. KCSM and Ferromex both initiated administrative proceedings seeking a determination by the SCT of the rates that KCSM and Ferromex should pay each other in connection with the Services. The SCT issued rulings in 2002 and 2008 setting the rates for the Services and both KCSM and Ferromex challenged these rulings. Although KCSM and Ferromex have challenged these matters based on different grounds and these cases continue to evolve, management believes the amounts recorded related to these matters are adequate. While the outcome of these matters cannot be predicted with certainty, the Company does not believe that, when resolved, these disputes will have a material effect on its consolidated financial statements.
	Contractual Agreements. In the normal course of business, the Company enters into various contractual agreements related to commercial arrangements and the use of other railroads’ or governmental entities’ infrastructure needed for the operations of the business. The Company is involved or may become involved in certain disputes involving transportation rates, product loss or damage, charges, and interpretations related to these agreements. While the outcome of these matters cannot be predicted with certainty, the Company does not believe that, when resolved, these disputes will have a material effect on its consolidated financial statements.
	Credit Risk. The Company continually monitors risks related to economic changes and certain customer receivables concentrations. Significant changes in customer concentration or payment terms, deterioration of customer creditworthiness or further weakening in economic trends could have a significant impact on the collectability of the Company’s receivables and its operating results. If the financial condition of the Company’s customers were to deteriorate and result in an impairment of their ability to make payments, additional allowances may be required. The Company has recorded provisions for uncollectability based on its best estimate at March 31, 2014.
	Income Tax. Tax returns filed in the U.S. for periods after 2009 and in Mexico for periods after 2007 remain open to examination by the taxing authorities. In 2014, the Internal Revenue Service (“IRS”) initiated an examination on the 2011 and 2012 U.S. federal tax returns and the Servicio de Administración Tributaria (the “SAT”), the Mexican equivalent of the IRS, initiated an examination on the 2012 tax return of KCSM Servicios. KCSM’s 2007 and 2010 tax returns are currently under examination by the SAT. The Company is litigating an audit assessment from the SAT for KCSM for the year ended December 31, 2005. The Company believes it is more likely than not that it will prevail in challenging the KCSM 2005 assessment. While the outcome of this matter cannot be predicted with certainty, the Company does not believe, when resolved, that this dispute will have a material effect on its consolidated financial statements. However, an unexpected adverse resolution could have a material effect on the consolidated financial statements in a particular quarter or fiscal year.
	Tax Contingencies. KCSM has not historically assessed Value Added Tax (“VAT”) on international import transportation services provided to its customers based on a written ruling that KCSM obtained from the SAT in 2008 stating that such services were exempt from VAT (the “2008 Ruling”). Notwithstanding the 2008 Ruling, in December 2013, the SAT unofficially informed KCSM of an intended implementation of a new criteria effective as of January 1, 2014, pursuant to which VAT would be assessed on all international import transportation services on the portion of the services provided within Mexico.  Additionally, in November 2013, the SAT filed an action to nullify the 2008 Ruling, potentially exposing the application of the new criteria to open tax years. In February 2014, KCSM filed an action opposing the SAT’s nullification action.  While the SAT’s unofficial communication to KCSM is not enforceable and the 2008 Ruling continues to be in effect, KCSM notified its customers in December 2013 of the potential assessment of VAT on international import transportation services as of January 1, 2014, and is addressing required changes in KCSM billing systems; however, implementation of any VAT assessment will depend on future developments and guidance expected to be published by the SAT. Due to the pass-through nature of VAT assessed on services provided to customers, the Company does not believe any ultimate requirement to assess VAT on international import transportation services will have a significant effect on its consolidated financial statements. However, unexpected adverse implementation criteria imposed by the SAT for open tax years could have a material effect on the consolidated financial statements of the Company in a particular quarter or fiscal year.
	Mexican Regulatory Railroad Service Law.  In Mexico, proposed legislation was introduced in 2013 in the House of Deputies to amend certain provisions in the Mexican Regulatory Railroad Service Law.  In February 2014, this proposed legislation was approved by the Mexican House of Deputies.  The proposed legislation is now before the Mexican Senate for consideration where it is expected to be amended.  The Mexican Senate is currently considering implementation legislation for telecommunications, antitrust, energy and election reform and the proposed rail legislation has been set aside and may not be acted on by the Senate in this congressional period which ends on April 30, 2014. If not acted on in the current congressional period, the rail legislation would likely be considered in the next congressional period, which begins September 1, 2014.  Because any final legislation is still subject to discussion and change in the Mexican Senate, and requires the signature of the President of Mexico, it is too early to determine what, if any, impact the proposed rail legislation could have on the Mexican railroad industry and its customers.  The Mexican Congress is also considering reform of its antitrust laws which if approved would replace the existing antitrust law effective since 1993.  Legislation amending the Mexican Regulatory Railroad Service Law and the Mexican antitrust law if approved could have a material adverse effect on the Company’s consolidated financial statements.
	Panama Canal Railway Company (“PCRC”) Guarantees and Indemnities. At March 31, 2014, the Company had issued and outstanding $5.3 million under a standby letter of credit to fulfill its obligation to fund fifty percent of the debt service reserve or liquidity reserve established by PCRC in connection with the issuance of the 7.0% Senior Secured Notes due November 1, 2026 (the “PCRC Notes”). Additionally, KCS has pledged its shares of PCRC as security for the PCRC Notes.
