KAVACH System in Trains to Prevent Accidents



  • The Indian Railways has recently made a provision of Rs 272.30 crore in Financial Year 2022-23 for the implementation of KAVACH.

About Kavach System:

  • Indian Railways has indigenously developed an automatic train protection system rechristened as ‘Kavach’ (Train Collision Avoidance System), to prevent accidents due to human error resulting in Signal Passing at danger and over-speeding.
  • It is a set of electronic devices and Radio Frequency Identification devices installed in locomotives, in the signalling system as well the tracks, that talk to each other using ultra high radio frequencies to control the brakes of trains and also alert drivers, all based on the logic programmed into them.
  • One of its features is that by continuously refreshing the movement information of a train, it is able to send out triggers when a loco pilot jumps signal, called Signal Passed at Danger (SPAD), a grave offence in railway operations with respect to safety, and the key to accidents like collision.
  • The devices also continuously relay the signals ahead to the locomotive, making it useful for loco pilots in low visibility, especially during dense fog.
