Sioux (train)

The Sioux was a named passenger train of the Milwaukee Road that operated between Chicago, Madison, Wisconsin, and Rapid City, South Dakota, via Prairie du Chien, Wisconsin and northern Iowa. The train operated coaches, diners and sleeping cars though most of its history.

In the latter years of the 1950s, the Sioux operated a non-stop service between Chicago's Union Station and Madison, Wisconsin. On that route, the train included a dining car serving breakfast, and a first-class parlor car. West of Madison the train carried a sleeping car and coaches. West of Madison it also operated as a mail train, making frequent stops. The train crossed the Mississippi River on the Pile–Pontoon Railroad Bridge.

On October 1, 1951, the train was cut back to a Chicago to Canton, South Dakota, service with prepaid taxi connections to nearby Sioux Falls. In 1960 the train was further cut back to a Chicago to Madison coach service. The train ceased operation on May 1, 1971, when Amtrak assumed responsibility for providing a national rail service.
