Provide funding for regional rail authorities

This bill creates a dedicated funding account for regional rail authorities in Montana by allocating a portion of rental car sales and use tax revenue. The money will be distributed annually by the Department of Transportation to rail authorities established before January 1, 2025, and can be used for administrative costs, matching federal grants, and developing cooperative transportation relationships. Funds may also support planning, designing, and operating rail projects that improve safety and connectivity between train stations, airports, roads, and other transit systems, including exploring north-south rail service corridors. The legislation amends existing state statutes to establish these distribution requirements and funding purposes.
