Kavach - Train Collision Protection

Kavach is Indian Railways' home-grown Automatic Train Protection system: it warns the loco pilot when a train overruns a signal or closes on another on the same line, and brakes the train itself if the warning is ignored. It is in the news because on 28 September 2026 the Railways cleared Rs 223 crore to take Version 4.0 over 614.75 route km of Varanasi Division on North Eastern Railway, days after South Central Railway switched on its first 4.0 section.
