Mont. Code § 60-11-201
The governor or the governor's authorized representative may negotiate with the proper authority representing any other state to establish an agreement to enable Montana, in concert with other states, to submit an application to the rail passenger corporation for institution of rail passenger service under the provisions of the Rail Passenger Service Act, 45 U.S.C. 563(b), or any interstate or federal proposal for the purpose of maintaining or augmenting rail passenger service in the state. The governor may not participate in the submission of an application until the base agreement and any application have been approved by the legislature. However, the governor or the governor's authorized representative may enter into agreements to expand Amtrak rail passenger service under 45 U.S.C. 563(b), as that statute reads on July 1, 1985, subject to appropriation by the legislature.
