Railway Signalling Track Circuits | Closed TC | Open Track Circuit| Fed over track circuit A track circuit is a vehicle detection device in which the running rails form part of an electrical circuit. The boundaries of track circuit are marked by insulation joints on the rail and rails are bonded at rail joints for better conductivity. Uses […]

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 […]

Railway Signalling Track Circuit Interrupters Presentation Definition * Catch points and trap points are types of turnout which act as railway safety devices. * Catch Points Points are provided to derail vehicles running back on rising gradients. The points may only be Unworked if traffic is in one direction only. Catch points are used to derail vehicles that are out of control on steep […]

Railway Signalling Track Circuit Introduction 1. A Track circuit is an Electrical circuit of which the running Rail of a Railway track forms a part. It is employed for indicating the presence of Trains and thereby for controlling Signalling and Block equipment. For the device Track circuit, the following truly holds good. 2. ‘No single […]
