Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On July 12, 2011, Kansas City Southern (“KCS”), together with its wholly-owned subsidiary The Kansas City Southern Railway Company, as Borrower (“KCSR”), entered into an amended and restated credit agreement with certain subsidiaries named therein as guarantors (the “Subsidiary Guarantors”), the various financial institutions and other persons from time to time parties thereto (the “Lenders”), The Bank of Nova Scotia, as administrative agent and collateral agent for the Lenders (“Agent”), Bank of America, N.A., as syndication agent, Compass Bank, JPMorgan Chase Bank, N.A. and Morgan Stanley Bank, N.A., as co-documentation agents and Merrill Lynch, Pierce, Fenner & Smith Incorporated and The Bank of Nova Scotia as joint lead arrangers and joint bookrunning managers (the “Credit Agreement”).

The Credit Agreement provides KCSR with (i) a five and one-half year $300 million term loan credit facility (the “Term Loan Facility”) and (ii) a five-year $200 million revolving credit facility consisting of (A) a revolving facility in an amount up to $200 million (the “Revolving Facility”), (ii) a letter of credit facility in an amount up to $25 million which constitutes usage under the Revolving Facility, and (iii) a swing line facility in an amount up to $15 million (the “Swing Line Facility”) which constitutes usage under the Revolving Facility.

The term loans under KCSR’s prior amended and restated credit agreement were combined and refinanced with those under the Term Loan Facility, and the maturity of such term loans was extended to 2017 under the Credit Agreement. KCSR used available cash to reduce the principal balance of the existing term loans by approximately $6 million. Commitments under KCSR’s prior revolving credit facility were rolled over into the new Revolving Facility, their maturity was extended and the available principal amount of such commitments was increased from $125 million to $200 million.

The outstanding principal balance of loans under the Term Loan Facility and the Revolving Facility bear interest at floating rates. At KCSR’s option, the loans will bear interest at either (i) the greater of (a) The Bank of Nova Scotia’s base rate, (b) federal funds rate plus 0.50% or (c) one-month LIBOR plus 1.00% (the “Base Rate”) plus a margin of 0.25% to 1.50% (depending on the leverage ratio) or (ii) LIBOR plus a margin of 1.25% to 2.50% (depending on the leverage ratio). The outstanding principal balance of loans under the Swing Line Facility will bear interest at the Base Rate plus a margin of 0.25% to 1.50% (depending on the leverage ratio).

KCSR is required to make quarterly principal payments on the Term Loan Facility commencing December 31, 2011, with any remaining unpaid principal balance due and payable on January 15, 2017.

The obligations under Credit Agreement are secured by substantially all of the assets of KCS, KCSR and the Subsidiary Guarantors pursuant to a Security Agreement dated July 12, 2011 (the “Security Agreement”), among KCS, KCSR, each Subsidiary Guarantor and Agent. In addition, KCS, KCSR and their restricted subsidiaries (as defined in the Credit Agreement) agreed to subordinate payment of certain intercompany debt, KCS and each Subsidiary

Guarantor guaranteed repayment of the amounts due under the Credit Agreement and the equity interests of KCSR and each Subsidiary Guarantor have been pledged pursuant to the Security Agreement to secure obligations under the Credit Agreement.

KCS and KCSR gave certain representations and warranties that are customary for credit agreements of this type. The Credit Agreement also contains affirmative and negative covenants that are customary for credit agreements of this type, including financial maintenance covenants related to a leverage ratio and an interest coverage ratio as defined in the Credit Agreement.

Events of default under the Credit Agreement are customary for transactions of this type and include, without limitation, non-payment of obligations; breach of any representation or warranty; non-performance of covenants and obligations; default on other indebtedness; certain judgments rendered; a change in control shall occur; bankruptcy or insolvency of KCS, KCSR, any restricted subsidiary or any Subsidiary Guarantor; and an impairment of security. The occurrence of an event of default could result in the acceleration of the repayment of any outstanding principal balance of the Term Loan Facility and the Revolving Facility.

A copy of the Credit Agreement and the Security Agreement are attached hereto as Exhibits 10.1 and 10.2, respectively. The foregoing is a summary of the terms of these agreements and does not purport to be a complete discussion of them. The Credit Agreement and the Security Agreement are incorporated herein by reference.
