Friends Centralized Track Control (CTC)



Please report any problems with the signal system to signals@friendstm.org

CTC System
Friends signaled track is monitored by computer software running in the Central Station Signal Tower. This software communicates with the circuitry in the field via a radio link to monitor the movement of trains, identify problems, and to provide diagnostic information. Status from the system is automatically uploaded to this website as conditions change. Click here for information on the hardware components used in the field.
