Railroad Signal Light, Detroit, Toledo & Ironton Railroad, May-June 1926
01
Artifact Overview
Traffic on many railroads is controlled by an automatic block signaling system. A railroad line is sectioned into blocks, and an electrical circuit in the track detects whether a train is in a given block. The circuit then operates differently colored signal lights, like these, that instruct an engineer how to proceed -- similar to an automobile traffic light.
