There are several passenger rail projects being discussed in Minnesota. There is one existing commuter rail service in the state, the Northstar Line, and one existing long-distance intercity rail service, the Empire Builder. Future projects include a mixture of short-distance commuter rail and medium-distance regional rail lines which would run from the Twin Cities outward to neighboring states and perhaps Canada. This article is focused on heavy-rail projects and does not discuss potential light rail lines in the core Twin Cities area.
