The bill prohibits any expenditures related to the Northern Lights Express passenger rail project, which is defined as the proposed high-speed rail service between Minneapolis and Duluth. It specifically mandates that the Commissioner of Transportation and the Metropolitan Council are not allowed to spend any funds on activities associated with the project, including studying, planning, preliminary engineering, final design, or construction. This prohibition extends to grants to other entities and the use of federal funds for these purposes.

The effective date of this prohibition is set for the day following the final enactment of the bill. The legislation aims to halt any financial commitment or resource allocation towards the Northern Lights Express project, reflecting a significant shift in transportation funding priorities within the state.
