DELHI (Metro Rail News): The successful trial of Kavach which is an indigenous Automatic Train Protection (ATP) System for enhancing the safety of running trains has been conducted today in the presence of Shri Ashwini Vaishnaw, Minister of Railways. During the trial, the driver didn’t stop the train but the train stopped automatically when it sensed another train coming from the other side avoiding a collision. Kavach conforms to SIL (Safety Integrity Level)-4 which is to the highest level of safety certification.

Kavach has been developed indigenously by research designs and standards organization (RDSO) in association with three Indian Vendors. According to Indian Railways, it is the cheapest yet the best protection system in the world. KAVACH has this unique feature that initiates automatic whistling without any intervention from the Loco pilot. The amalgamation of technologies such as Relay Based, UHF Radio, RFID, GSM and GPS will collectively aid in the effective and smooth functioning of this system.

Announced in the 2022 Union Budget as part of the Atmanirbhar Bharat initiative, 2000 Km of the rail network is planned to be brought under Kavach. In addition to the trial section of 250 km, at present Kavach is under implementation on 1200 Route km of South-Central Railway.

It has been deployed on over 1098 Route Kms & 65 locos in ongoing projects of South-Central Railway. It is planned to be implemented on Delhi–Mumbai & Delhi–Howrah corridors as a part of the “Mission Raftar” project.

To make Kavach a world class ATP system the few additional features that will be incorporated in the future are:

  • Direct interface with Interlocking
  • Functionality for Temporary Speed Restrictions
  • Development of Balise for Kavach
  • Development of Kavach on LTE

This system creates a safety envelop around trains and if two trains approach each other, then both automatically stop. This will also help in bad weather conditions and foggy weather when there are chances of more accidents
