Indian Railways is installing Kavach 4.0 in a phased manner on India's two busiest rail corridors -- Delhi–Mumbai and Delhi–Howrah -- to enhance safety. Railway Minister Ashwini Vaishnaw on Friday informed the Rajya Sabha that work on the automatic train protection system is being carried out now at a fast pace and is giving good results.

What is Kavach?

It is an indigenously developed, upgraded version of the Automatic Train Protection (ATP) system. The Kavach is a highly technology-intensive system, which requires safety certification of the highest order (SIL-4). It aids the Loco Pilot in running trains within specified speed limits by automatic application of brakes in case the Loco Pilot fails to do so, and also helps the trains to run safely during inclement weather.
