The Twin Cities-Milwaukee-Chicago (TCMC) Intercity Passenger Rail Project adds a second daily round-trip passenger train on the 411-mile corridor between Chicago, Illinois and Twin Cities (St. Paul and Minneapolis) in Minnesota. The TCMC Service will follow Amtrak's existing long-distance Empire Builder route. The new service will complement the existing Empire Builder schedule, providing travel flexibility with both a morning and mid-day departure from Chicago and St. Paul.
