TCM Track Circuit Monitoring

Track Circuit Monitoring (TCM) systems can predict track circuit failures and capture intermittent faults.

Track circuits are a vital part of many signaling systems and maintaining their performance is fundamental to the safety and efficiency of the rail network. The Track Circuit Monitor (TCM) reliably identifies deterioration in track circuit performance and issues alerts to allow maintenance before failure. A non-invasive sensor monitors energy levels at the track circuit receiver and sends real-time data to a central server where it is analyzed using specialist software with preset multiband alarm levels to detect when the operating characteristics of a track circuit start to deteriorate. Alarm events are sent to designated users who can react immediately and initiate necessary actions in a timely manner.
