The Calumet, also commonly called the Valpo Local, was a 43.6-mile (70.2 km) passenger train route operated by Amtrak between Chicago and Valparaiso, Indiana.

Transferred from Conrail in 1979, the full route was shared with Amtrak's Broadway Limited until 1990; the Calumet was discontinued the next year.

[7] Representative Peter J. Visclosky introduced a bill to require Amtrak to continue operations until July 1, 1991 to allow time for the State of Indiana to consider subsidizing the route.

[8] The date was changed to May 6 and the mandate was included in an amendment to the Independent Safety Board Act of 1974, signed into law November 28, 1990, by U.S. President George H. W.

[4][11] Commuter service from Chicago into northern Indiana is still provided by the South Shore Line, operated by the Northern Indiana Commuter Transportation District over its own alignment, whose closest stop, Dune Park station, is 15 miles (24 km) from Valparaiso, closer to Lake Michigan.
