Kavach’, the indigenously developed Automatic Train Protection (ATP) system, will be deployed across the entire rail network beginning with 2,000 km in the 2022-23 fiscal and will be rolled out in 4,000 to 5,000 km every subsequent year. ‘Kavach’, which literally means armour, is being promoted by the Railways as the world’s cheapest automatic train collision protection system. ‘Kavach’ is designed to bring a train to a halt automatically when it notices another train on the same line within a prescribed distance. Trains will also stop on their own when digital system notices any manual error like jumping of the red signal or any other malfunction. ‘Kavach’ is developed by Research Design and Standards Organization (RDSO) in collaboration with Indian industry.
