In the distance you can see the signals at the junction of the branch line to St. Louis. In 1949, C&NW installed GRS CTC between Nelson, IL and Malta on 40 miles of double track. This was extended to Chicago in 1950. The CTC machine in Chicago had 67 levers controlling 63 switches. At the time, it had the longest stretch of double track under CTC control with both tracks signaled in each direction. Disk 79
