In 1881, the "cutoff" opened between Godfrey and Wann, bypassing the main part of Alton and presently used by Amtrak. While the original route through Alton was eventually abandoned. Through Springfield between Ridgely and Iles, double track was constructed between 1891 and 1893. CTC did not eliminate this double track until the 1980's. At its peak, the only single track segments were between Rinaker and Plainview, and between Godfrey and Wann. CTC was installed between Rinaker and Plainview in 1933, and between Godfrey and Wann in 1940, originally controlled from various towers as linked below.
