“If a State desires to select or selects an entity other than Amtrak to provide services required for the operation of an intercity passenger train route described in section 24102(7)(D) or 24702 of title 49, United States Code, the State may make an agreement with Amtrak to use facilities and equipment of, or have services provided by, Amtrak under terms agreed to by the State and Amtrak to enable the State to utilize an entity other than Amtrak to provide services required for operation of the route. If the parties cannot agree upon terms, and the Surface Transportation Board finds that access to Amtrak’s facilities or equipment, or the provision of services by Amtrak, is necessary to carry out this provision and that the operation of Amtrak’s other services will not be impaired thereby, the Surface Transportation Board shall, within 120 days after submission of the dispute, issue an order that the facilities and equipment be made available, and that services be provided, by Amtrak, and shall determine reasonable compensation, liability, and other terms for use of the facilities and equipment and provision of the services. Compensation shall be determined, as appropriate, in accordance with the methodology established pursuant to section 209 of this division [49 U.S.C. 24101 note], if available.”
