The Loop was a daily passenger train operated by Amtrak between Chicago and Springfield, Illinois.

The Loop began on April 27, 1986, with funding support from the state of Illinois.

The train acted as a counterpart to the State House, departing Chicago in the morning and returning in the afternoon.

Funding shortfalls eliminated Saturday service in mid-1995, and the train ended altogether on June 28, 1996, after Illinois withdrew its support.
