The Indian Railways conducted an anti-collision test to check its indigenous developed system to avoid train accidents.

It took place on March 4, with India's Railway Minister Ashwini Vaishnaw overseeing the test conducted by the Indian Railways in southern India's Secunderabad.

Visuals showed the engineers demonstrating the system during the train's run to the lawmaker. The train speeds up, but then starts to slow down as it reaches the speed deemed dangerous by the tracker. It also showed that the pilot failed to start the engine as the locomotive was in the proximity of another train.

Known as Kavach -- which translated to shield or armour -- the automatic train protection system stopped the train 380 meters of the other locomotive.

The minister and the team declared the test successful, following the demonstration. Once implemented, the Kavach system will enable trains to stop on their own whenever the system notices any manual error or a malfunction.

The system will cost the Indian Railways INR 50 lakh (USD $65,622.10) per kilometer.

"It works on the principle of continuous update of movement by using high frequency radio communication. It also conforms to SIL-4 (Safety Integrity Level - 4) which is the highest level of safety certification," an official was quoted in the media as saying.

"RFID tags are provided on the tracks and at the station yard for each track and signals for track identification, location of trains and identification of train direction. The 'On Board Display of Signal Aspect' (OBDSA) is to help loco pilots check signals on board consoles even when the visibility is low."

The new system has been deployed on over 1098 route km and 65 locos in on-going projects of South Central Railway, reports said.
