TDM Train Detection Monitoring

Train Detection Monitoring (TDM) systems can predict failures of various train detection methods and capture intermittent faults.

The various methods of train detection (including track circuit or axcle counter) are a vital part of many signaling systems and maintaining their performance is fundamental to the safety and efficiency of the rail network. TDM reliably identifies deterioration in performance and issues alerts to allow maintenance before failure. Non-invasive sensors monitor for example energy levels at the track circuit receiver and send 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.
