Indian Railways to Implement Kavach System to Prevent Train Collisions

The Indian Railways is introducing a new safety system called Kavach to prevent train accidents. This system uses technology that integrates the train engine, track, and signals to warn drivers of potential collisions. Chips placed every 4 kilometres along the track communicate with the train, creating a protective zone. As a first step, Southern Railway plans to deploy Kavach over 271 kilometres across three key routes in the Chennai region.


To enhance train safety, the Indian Railways is deploying a new technology called Kavach (meaning "armour" in Hindi) across several routes in the Chennai division. This system creates a protective layer by integrating train engines, tracks, and signals. Chips are installed every 4 kilometers along the railway track, which communicate with the trains and alert drivers of potential collision risks.


Southern Railway has issued a tender to implement Kavach technology on a 271 kilometer stretch across three key routes:

  • Chennai Central - Arakkonam
  • Arakkonam - Renigunda
  • Chennai Central - Gudur

This initiative signifies a significant step towards improving train safety and passenger well-being on these important routes.
