The Gilman, Clinton and Springfield Railroad was a railroad of 111 miles in length, chartered in 1867, that operated from 1871 until 1877 in the U.S. state of Illinois. It provided service from Springfield, the state capital, to Gilman, a junction point on the main line of the much larger Illinois Central Railroad. After operation for a short period as an independent short line, the Gilman, Clinton and Springfield underwent financial failure and was merged into the Chicago and Springfield Railroad, an affiliate of the Illinois Central.
