India tests home-grown train collision prevention system ‘Kavach’: How it works | India News – Times of India


NEW DELHI: Railway minister Ashwini Vaishnaw on Friday witnessed the functioning of “Kavach“, an indigenously developed automatic train protection system.
The system, which successfully passed the anti-collision test in Hyderabad, is dubbed as a “phenomenal improvement in safety and a great contribution to accident prevention”.
The railways is also promoting Kavach, which literally means armour, as the world’s cheapest automatic train collision protection system.
Here’s all you need to know:
Major milestone
* Ashwini witnessed the on-site demonstration of the system on Friday. The demonstration took place between Gullaguda and Chitgidda railway stations on Lingampalli–Vikarabad section of Secunderabad Division in South Central Railway (SCR).
* As part of the demo, Vaishnaw was travelling in a locomotive in one direction, while Vinay Kumar Tripathi, Chairman and CEO, Railway Board was travelling in another on the opposite direction on the same track and ‘Kavach’ worked as desired to stop the trains and avert a collision.
* The railway minister described the successful demo as a major milestone in the history of Indian Railways.
How Kavach works
* 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.
* The ‘On-Board Display of Signal Aspect’ (OBDSA) is to help loco pilots check signals on board consoles.
* RFID tags are provided on the tracks and at station yard for each track and signals for track identification, location of trains and identification of train direction.
* Once the system is activated, all trains within a 5-km range will halt to provide protection for trains on adjacent tracks. Currently, loco-pilots or assistant loco-pilots usually crane their necks out of the window to look out for caution signs and signals, said officials.
* Kavach It also includes stationary equipment to gather signaling and loco inputs and relay them to a central system for seamless communication with the train crew and stations.
More about the game-changer technology
* Kavach is designed, developed and manufactured by the Research Design and Standards Organisation (RDSO) in collaboration with Indian industry.
* The 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.
* The technology has been tested at SIL-4 (Safety Integrity Level- 4) which is the highest level of safety and integrity.
