Indian Railways Successfully Tests Anti-Collision System 'Kavach', Here's How It Works

New Delhi: Indian Railways on Friday successfully tested an Automatic Train Protection (ATP) named 'Kavach'.

In a bid to test this system, two trains were put on same track with a distance of a few meters of which one train had a Union Minister of Railways Ashwini Vaishnav on board. Since, the train with Union Minister was approaching towards the other train, Kavach acted and the stopped the train 380 meters before it collided with the train coming from the front.

Kavach was live tested at Secunderabad, Telangana. Along with Railway Minister, the chairman of the Railway Board and other senior officials were present during the testing but in the second train coming from the front. The test was conducted on the Sanathnagar-Shankarpalli section.

Taking to the micro-blogging site twitter, the Railway Minister shared video of the same.

''SPAD test, tried crossing signal at red. Kavach is protecting and not allowing the Loco to move,'' he tweeted.

Kavach is an indigenous technology which can prevent two trains from colliding with each other. It is the world's cheapest rail safety technology and it has been developed to achieve the goal of 'Zero Train Accident'.

What is 'Kavach', how does it work?

-- It is an indigenously developed Automatic Train Protection (ATP) system. The armor is designed to stop a train automatically.

-- When the digital system detects any manual error like red signal or any other fault, through this technology the train passing through the respective route automatically stops.

-- After implementing this technology, its operation will cost Rs 50 lakh per kilometer.

-- It is very less as compared to other countries. Worldwide, about two crore rupees are spent on such technology.

-- In this technique, when the train passes through such a signal, where it is not allowed to pass, then a danger signal is sent through it.

-- If the loco pilot fails to stop the train, then 'Kavach' technology, will automatically apply the brakes of the train.

-- Kavach technology works on high frequency radio communication. It also verifies to SIL-4 (System Integrity Level-4). This is the highest level of Railway Safety Certification.
