What is indian railways anti collision sytem, Kavach?


| Posted on

A 'Quasi' technology that adds an 'Extra Layer of Safety' to train operations to prevent 'dangerous' Train Accidents caused by 'Human Mistakes or Limitations' and 'Mechanical Failures.' Railway Minister Ashwini Vaishnaw conducted a live test of Kavach, an indigenously designed autonomous train protection technology, on World Safety Day.


The test featured two trains traveling at full speed towards each other and stopping automatically once they detected an opposing train on the same line within a specified distance. The minister was in Secunderabad for the trial and has firsthand knowledge of Kavach.




The Indian Railway has developed its own indigenous Automatic Train Protection (ATP) System known as "Kavach" to improve the safety of moving trains and their passengers. Kavach, which literally means armor, is being promoted by the railways as the world's cheapest automatic train collision protection equipment. Kavach was put to the test today in Secunderabad, as two trains sped towards each other, one carrying Railway Minister Ashwini Vaishnaw and the other the Chairman of the Railway Board. They did not collide, though, thanks to indigenous 'KAVACH' technology.


Kavach was designed to assist the railways in meeting their aim of "zero accidents." Its purpose is to automatically bring a train to a halt when it detects another train distance.

The anti-collision test undertaken by the Indian Railways to check the indigenously designed technology to avert rail accidents, known as the 'Kavach' System, has been declared successful by Railway Minister Ashwini Vaishnav. Today, he conducted an on-site assessment near Secunderabad.

According to the railway officials, once implemented, it will cost 50 lakh rupees per kilometer to operate, compared to around 2 crore rupees globally.


  • Head-on, rear-end, and side collision detection and prevention — A UNIQUE feature even when a train is not protected by a signal, such as in a block section.
  •  Train Parting / Jumbling Detection & Generation - As a result, any incoming train will be brought to a halt bringing the adjacent line to a halt.
  •  At Level Crossings, a 'Train Approach' warning is displayed for road users manned and unmanned - Furthermore, at manned non-interlocked level crossings, which slows the train to a crawl. If the gate is detected as being open, the speed limit is reduced to 30 km/h through ACD Gate.
