Track Circuit Interrupter Railway * Track circuit interrupters are Emergency stop devices. These are provided at designated locations to provide a vital indication that a train has run into a portion of track in which movements are not permitted (e.g. into trap points or Catch points or past FRLs at terminal platforms). * It […]
