Kavach, an Automatic Train Protection (ATP) system developed by the Indian Railways, lived up to its name and passed a key anti-collision test with flying colours on Friday.
Two trains on the same track hurtled towards each other at top speed. One train had a Union minister on board. But thanks to ‘Kavach’, the two locomotives did not collide.
Kavach, an Automatic Train Protection (ATP) system developed by the Indian Railways, lived up to its name and passed a key anti-collision test with flying colours on Friday.
Built with the goal of zero accidents, Kavach was live tested at Secunderabad, with Union Minister for Railways Ashwini Vaishnaw at the helm along with the driver of the train and other officials who were present for the trial.
A minute-long video shows the successful test of the anti-collision system. The clip begins with Union Minister Ashwini Vaishnaw describing how the train he is on is on the same track as another one coming from the opposite direction.

When the train attempts to bypass the stop signal, it comes to a halt and Vaishnaw says the Kavach system doesn’t let the locomotives advance.
This mechanism kicks in when a signal is passed at danger (SPAD) or when a train passes a stop-signal when not allowed to do so. Kavach controls the speed of the train by an automatic application of brakes in case the loco pilot fails to do so.
