Abstract
A system and method for detecting broken rails in a track of parallel rails includes at least one first broken rail detection module configured to measure a current through the track and a central control system configured to determine a location of at least one train on the track. The at least one first broken rail detection module is configured to send the central control system a signal based on the measured current. The central control office is configured to determine if a broken rail exists on the track and/or a location of the broken rail on the track based at least partially on the measured current and the location of the at least one train on the track.
