Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In the opinion of the management of KCS, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal and recurring adjustments) necessary to reflect a fair statement of the results for interim periods in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), 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, 2021. The results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results to be expected for the full year ending December 31, 2022. On September 15, 2021, KCS and Canadian Pacific Railway Limited (“CP”), a Canadian corporation, entered into a merger agreement (the “Merger Agreement”) and on December 14, 2021, CP acquired the outstanding common and preferred stock of KCS. Therefore, earnings per share data is not presented as the Company does not have any outstanding or issued publicly traded stock. The merger is further discussed in Note 2, Merger Agreement. In November 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2021-10, Government Assistance (Topic 832), Disclosures by Business Entities about Government Assistance. The standard is intended to increase transparency of government assistance by requiring disclosures of the following: (1) the types of assistance, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on the entity’s financial statements. This ASU was effective for the Company on January 1, 2022 and the Company adopted the ASU prospectively. See Note 4, Property and Equipment for the newly required disclosure.

Merger Agreement

Merger Agreement	9 Months Ended
Merger Agreement	Sep. 30, 2022
Business Combinations [Abstract]
Merger Agreement	Merger Agreement On December 14, 2021, CP acquired the outstanding common and preferred stock of KCS. Each share of common stock, par value $0.01 per share, of KCS that was outstanding immediately prior to the merger was converted into the right to receive (1) 2.884 common shares of CP and (2) $90 in cash (together, the “Merger Consideration”), and each share of preferred stock, par value $25 per share, that was outstanding immediately prior to the merger was converted into the right to receive $37.50 in cash. The Merger Consideration value received by KCS stockholders was $301.20 per KCS common share. The merger transaction was completed through a series of mergers as outlined in the Merger Agreement. These mergers ultimately resulted in KCS being merged with and into Cygnus Merger Sub 1 Corporation (“Surviving Merger Sub”), a wholly owned subsidiary of CP, with Surviving Merger Sub continuing as the surviving entity. Pursuant to the Merger Agreement, Surviving Merger Sub was renamed “Kansas City Southern” and as successor company of KCS, continued to own the assets of KCS. Immediately following the consummation of the mergers, CP caused the contribution, directly and indirectly, of all of the outstanding shares of capital stock of Surviving Merger Sub, as successor to KCS, to be deposited into an independent, irrevocable voting trust (the “Voting Trust”) under a voting trust agreement (the “Voting Trust Agreement”) approved by the U.S. Surface Transportation Board (“STB”), pending receipt of the final and non-appealable approval or exemption by the STB pursuant to 49 U.S.C. § 11323 et seq., of the transactions contemplated by the Merger Agreement (“STB Final Approval”). The Voting Trust prevents CP, or any affiliate of CP, from controlling or having the power to control KCS prior to STB Final Approval. Following receipt of STB Final Approval, the Voting Trust will be terminated and CP will acquire control over KCS’s railroad operations. On December 14, 2021, the merger of KCS and Surviving Merger Sub was accounted for as a recapitalization of KCS’s equity. Upon STB Final Approval, the transaction will be accounted for as a business combination using the acquisition method of accounting. Pursuant to the Merger Agreement, KCS paid a cash dividend in the first and third quarters of 2022 of $265.0 million and $200.0 million, respectively, to a wholly-owned subsidiary of CP. Periodic cash distributions may be made to a wholly-owned subsidiary of CP based upon cash generated, the timing of capital expenditures and working capital needs of the Company. For the three and nine months ended September 30, 2022, KCS reported $11.5 million and $36.8 million, respectively, of merger-related costs, which primarily related to incentive compensation costs. During the three and nine months ended September 30, 2021, the Company recognized merger-related costs of $36.5 million and $776.6 million, respectively. For the three months ended September 30, 2021, the merger costs primarily related to compensation and benefits costs and legal fees. For the nine months ended

The Company has historically received assistance from governmental entities, typically in the form of cash, for purposes of making improvements to its rail network as part of public safety and/or economic revitalization initiatives. The governmental entity generally specifies how the monetary assistance is to be spent, and may include limited conditions requiring the Company to return the assistance. The Company accounts for this assistance received as reductions to property and equipment in the period in which the improvement is made, with the assistance being amortized as an offset to depreciation expense over the life of the improvement. As of September 30, 2022 and December 31, 2021, the total governmental assistance received, net of accumulated amortization, was $35.5 million and $37.3 million, respectively. For the three and nine months ended September 30, 2022, governmental assistance amortization was $0.7 million and $1.9 million, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company’s derivative financial instruments are measured at fair value on a recurring basis and consist of foreign currency forward contracts and treasury lock agreements, which are classified as Level 2 valuations. 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 and in the case of option contracts, volatility, the risk-free interest rate and the time to expiration. The Company’s short-term financial instruments include cash and cash equivalents, accounts receivable, accounts payable and short-term borrowings. 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 carrying value of the Company’s debt was $3,781.6 million and $3,777.6 million at September 30, 2022 and December 31, 2021, 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 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 September 30, 2022, the Company did not expect any losses as a result of default of its counterparties. Interest Rate Derivative Instruments . In 2020, the Company executed six 30-year treasury lock agreements with an aggregate notional value of $650.0 million and a weighted average interest rate of 1.58%. The purpose of the treasury locks is to hedge the U.S. Treasury benchmark interest rate associated with future interest payments related to the anticipated refinancing of the $444.7 million principal amount of 3.00% senior notes due May 15, 2023 (the “3.00% Senior Notes”) and the $200.0 million principal amount of 3.85% senior notes due November 15, 2023 (the “3.85% Senior Notes”). The Company has designated the treasury locks as cash flow hedges and recorded unrealized gains and losses in accumulated other comprehensive income (loss). For the nine months ended September 30, 2022, the total unrealized gain of $232.2 million recognized in accumulated other comprehensive income increased by $174.8 million compared to December 31, 2021, reflecting a change in the value of the treasury locks as U.S. treasury rates rose. Upon settlement, the unrealized gain or loss in accumulated other comprehensive income (loss) will be amortized to interest expense over the life of the future underlying debt issuance. Foreign Currency Derivative Instruments. The Company’s Mexican subsidiaries have net U.S. dollar-denominated monetary liabilities 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 in the consolidated statements of operations and the amount of income taxes paid in Mexico. The Company also has net monetary assets denominated in Mexican pesos that are subject to periodic re-measurement and settlement that create fluctuations in foreign currency gains and losses in the consolidated statements of operations. The Company hedges its net exposure to foreign currency fluctuations in earnings by entering into foreign currency forward contracts. The foreign currency forward contracts involve the Company’s agreement to buy or sell pesos at an agreed-upon exchange rate on a future date. Below is a summary of the Company’s 2022 and 2021 foreign currency derivative contracts (amounts in millions, except Ps./USD) : Foreign currency forward contracts Contracts to sell Ps./receive USD Offsetting contracts to purchase Ps./pay USD Notional amount Notional amount Weighted-average exchange rate (in Ps./USD) Notional amount Notional amount Weighted-average exchange rate (in Ps./USD) Cash received/(paid) on settlement Contracts executed in 2022 and outstanding $ 460.0 Ps. 9,797.1 Ps. 21.3 — — — — Contracts executed in 2022 and settled in 2022 $ 50.0 Ps. 1,105.3 Ps. 22.1 $ 50.5 Ps. 1,105.3 Ps. 21.9 $ (0.5) Contracts executed in 2021 and settled in 2022 $ 270.0 Ps. 5,583.3 Ps. 20.7 $ 271.7 Ps. 5,583.3 Ps. 20.6 $ (1.7) Contracts to purchase Ps./pay USD Offsetting contracts to sell Ps./receive USD Notional amount Notional amount Weighted-average exchange rate (in Ps./USD) Notional amount Notional amount Weighted-average exchange rate (in Ps./USD) Cash received/(paid) on settlement Contracts executed in 2021 and settled in 2021 (i) $ 100.0 Ps. 1,993.5 Ps. 19.9 $ 98.1 Ps. 1,993.5 Ps. 20.3 $ (1.9) (i) During the nine months ended September 2021, the Company settled $100.0 million of these forward contracts, resulting in cash paid of $1.9 million. The Company has not designated any of the foreign currency derivative contracts as hedging instruments for accounting purposes. The Company measures the foreign currency derivative contracts at fair value each period and recognizes any change in fair value in foreign exchange gain (loss) within the consolidated statements of operations. The cash flows associated with these instruments is classified as an operating activity within the consolidated statements of cash flows. Offsetting. The Company’s treasury lock agreements and foreign currency forward contracts are executed with counterparties in the U.S. and are governed by International Swaps and Derivatives Association agreements that include standard netting arrangements. Asset and liability positions from contracts with the same counterparty are net settled upon maturity/expiration and presented on a net basis in the consolidated balance sheets prior to settlement.

Refundable Mexican Value Added Tax	Sep. 30, 2022
Accounts Receivable Additional Disclosures [Abstract]
Refundable Mexican Value Added Tax	Refundable Mexican Value Added Tax Kansas City Southern de México, S.A. de C.V. (“KCSM”) is not required to charge its customers value added tax (“VAT”) on international import or export transportation services, which prior to 2022 resulted in KCSM paying more VAT on its expenses than it collected from customers. These excess VAT payments are refundable by the Mexican government. Prior to 2019, Mexican companies could offset their monthly refundable VAT balance with other tax obligations. In January 2019, Mexico tax reform eliminated the ability to offset other tax obligations with refundable VAT. Over 2019 through 2021, KCSM generated a refundable VAT balance and filed refund claims with the Servicio de Administración Tributaria (the “SAT”), which have not been refunded. In November 2021, changes to the VAT law were announced and became effective beginning January 1, 2022. These changes reduced the recoverability of VAT paid by KCSM on its expenditures that support international import transportation service revenues that are not subject to a VAT charge. VAT that is unrecoverable from the Mexican government results in incremental VAT expense for KCSM. Beginning in 2022, KCSM changed certain service offerings to either require VAT to be charged to customers on revenue, or impose a rate increase to offset the incremental VAT expense. These measures implemented by KCSM increased the VAT to be collected from customers and payable to the Mexican government.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Concession Duty. Under KCSM’s 50-year railroad concession from the Mexican government (the “Concession”), which could expire in 2047 unless extended, KCSM pays annual concession duty expense of 1.25% of gross revenues. For the three and nine months ended September 30, 2022, the concession duty expense, which is recorded within materials and other in operating expenses, was $5.5 million and $16.0 million, respectively, compared to $4.7 million and $14.1 million, for the same periods in 2021. Litigation. Occasionally, the Company is a party to various legal proceedings, regulatory examinations, investigations, administrative actions, and other legal matters, arising for the most part in the ordinary course of business, 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 that management believes are adequate to cover expected costs. The outcome of litigation and other legal matters is always uncertain. KCS believes it has valid defenses to the legal matters currently pending against it, is defending itself vigorously, and has recorded accruals determined in accordance with U.S. GAAP, where appropriate. In making a determination regarding accruals, using available information, KCS evaluates the likelihood of an unfavorable outcome in legal or regulatory proceedings to which it is a party to and records a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of KCS’s defenses and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from the current estimates. It is possible that resolution of one or more of the legal matters currently pending or threatened could result in losses material to KCS’s consolidated results of operations, liquidity or financial condition. 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 Clean Water 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 costs 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 handle 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 September 30, 2022, is based on an updated actuarial study of personal injury claims through April 30, 2022, and review of the last five months’ experience. Although these estimates cannot be predicted with certainty, management believes that the ultimate outcome will not have a material adverse effect on the Company’s consolidated financial statements. Tax Contingencies . Tax returns filed in the U.S. for periods after 2015 and in Mexico for periods after 2012 remain open to examination by the taxing authority. The Internal Revenue Service (“IRS”) has completed its examination of the 2017 deemed mandatory repatriation tax included in the 2017 U.S. federal tax return and the 2016 U.S. federal tax return with no material impact to the consolidated financial statements. The Servicio de Administración Tributaria (the “SAT”), the Mexican equivalent of the IRS, has initiated examinations of the KCSM 2013 through 2020 Mexico tax returns and the Financiera Inspira, S.A. de C.V. SOFOM, E.N.R. 2016 and 2017 Mexico tax returns. The Company does not expect that these examinations will have a material impact on the consolidated financial statements. During 2017, the Company received audit assessments from the SAT for the KCSM 2009 and 2010 Mexico tax returns. The Company commenced administrative actions with the SAT and the audit assessments were subsequently nullified. In the third quarter of 2018, the SAT issued new assessments and the Company filed administrative appeals with the SAT. During the first quarter of 2022, the Company received an audit assessment from the SAT for the KCSM 2013 Mexico tax return and filed an administrative appeal of the assessment in the second quarter of 2022. On April 13, 2022, the SAT used an electronic tax mailbox to deliver an audit assessment on the 2014 KCSM tax returns, which as of September 30, 2022 was Ps.5.7 billion (approximately $280.0 million USD) of tax, interest, penalties and inflation (the “2014 Audit Assessment”). In 2014, KCSM filed an amparo lawsuit with the district court, objecting to the SAT’s electronic accounting requirements, including the SAT’s use of the electronic tax mailbox, and KCSM was granted a permanent injunction in 2015 preventing the SAT from delivering any notification of assessments using the electronic tax mailbox. The permanent injunction remained in effect through the date the SAT issued the 2014 Audit Assessment. The Company became aware of the 2014 Audit Assessment on June 30, 2022 and based on the permanent injunction on the electronic accounting requirements, the Company believed it had thirty business days from that date to file an appeal. On July 7, 2022, the Company filed an administrative appeal of the 2014 Audit Assessment with the SAT. During the third quarter of 2022, the SAT dismissed the administrative appeal of the 2014 Audit Assessment on the basis it wasn’t filed timely. The Company plans to challenge in Mexican court the SAT's use of the electronic mailbox and the dismissal of the administrative appeal of the 2014 Audit Assessment. The Company believes that it has strong legal arguments in its favor and it is more likely than not that the administrative appeal of the 2014 Audit Assessment was timely filed. The 2014 Audit Assessment includes tax positions where KCSM has prior favorable court decisions or strong legal arguments in its favor. Management believes it is more likely than not it will prevail in any challenge of the 2014 Audit Assessment. Historically, the Company has not been required to pay to settle previous SAT audit assessments or has settled SAT audit assessments for an immaterial amount. On July 1, 2022, the SAT froze KCSM’s Mexico bank accounts without any request for payment of the 2014 Audit Assessment or notification of the freeze. The Company filed an amparo lawsuit challenging the legality of the bank account freeze. The district court issued a permanent injunction requiring the SAT to remove the freeze subject to KCSM posting a performance bond or other collateral upon the SAT demonstrating a tax obligation exists. In August 2022, KCSM posted a performance bond in the amount of Ps.5.6 billion (approximately $278.0 million USD) and the bank account freeze was removed. The freeze and cost of obtaining the performance bond did not have a significant impact on KCSM’s cash flows or operations. The provision of the performance bond is not an agreement or concession with regard to the 2014 Audit Assessment and in no way impacts KCSM’s ability to further defend its tax position. The Company believes that it has strong legal arguments in its favor and it is more likely than not that it will prevail in any challenge of the assessments. U.S. Collective Bargaining. KCSR participates in industry-wide multi-employer bargaining as a member of the National Carriers’ Conference Committee (“NCCC”), as well as local bargaining for agreements that are limited to KCSR's property. Approximately 72% of KCSR employees are covered by collective bargaining agreements. For the 2016 bargaining round, 5-year agreements were reached voluntarily or through the arbitration process during 2017 and 2018 covering all of the participating unions. The terms of these agreements remain in effect until new agreements are reached in the 2020 national bargaining round. In November 2019, KCSR and its unions commenced negotiations in connection with the 2020 collective bargaining round. On July 15, 2022, President Biden signed an executive order creating a Presidential Emergency Board (“PEB”) to assist the railroads and its unions in ongoing national labor negotiations. The PEB reviewed the parties’ proposals, held hearings and issued non-binding settlement recommendations to the President. Under the terms of the PEB, the parties had until September 16, 2022 to reach a voluntary settlement based on those recommendations. On September 15, 2022, the NCCC and unions reached a tentative agreement resulting in the Company recognizing estimated retroactive union wages and bonuses of approximately $9.0 million in compensation and benefits on the consolidated statements of operations. The union ratification began in mid-September and is expected to be complete by mid-November. As of October 26, 2022, six of the twelve railroad unions have ratified their respective tentative agreements; however, the third largest union rejected the tentative agreement. The NCCC and this union agreed to continue negotiations through November 19, 2022, before the union seeks other self-help remedies, including strikes or work stoppages. Under the Railway Labor Act, Congress can impose a resolution based upon the PEB recommendations or order trains to operate as usual while the two sides continue to negotiate and ultimately reach a new agreement. A strike or work stoppage could result in a significant disruption of the Company’s operations and have significant financial impacts, such as lower revenues and higher operating costs. 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 believes that, when resolved, these disputes will not have a material effect on its consolidated financial statements. On July 14, 2022, KCSM reached an agreement with the Mexican Ministry of Infrastructure, Communications and Transportation (“SICT”) to fund a new investment in the Celaya-NBA Line Railway Bypass and related infrastructure in an amount not to exceed Ps.4.0 billion (approximately $200.0 million USD). In exchange for the investment, the SICT agreed to amend KCSM’s Concession Title effective July 14, 2022, to extend the exclusivity rights granted to KCSM for an additional period of 10 years. Under this amendment, KCSM’s exclusivity will now expire in 2037. 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, bankruptcy, insolvency or liquidation of a customer, or 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 credit losses based on its best estimate at September 30, 2022. Panama Canal Railway Company (“PCRC”) Guarantees and Indemnities. At September 30, 2022, the Company had issued and outstanding $5.7 million under a standby letter of credit to fulfill its obligation to fund fifty percent of the debt service reserve and 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.
