TCAS, collision avoidance system of trains successful

Hyderabad, Oct 18 (): Indian Railways has successfully tried out a technology called the Train Collision Avoidance System (TCAS), on Tuesday around 150 km away from Hyderabad.

TCAS technology is based on combination of Radio Frequency and GPS enabled technology. It applies brakes with no intervention of loco, the train pilots as soon as it spots another stationary or locomotive on the track and it avoids collision. This technology includes setting up of few electronic gadgets in station, in trains and along tracks.

A team of the railway officials headed by Vinay Mittal, the Chairman of Railway Board, Member of Electrical board, Kul Bhushan and V. Ramachandran Director General of Research Designs & Standards Organisation (RDSO), Lucknow watched the trial of TCAS. This technology is conjointly developed by the RDSO of Railways and a Hyderabad-based firm HBL Power Systems Ltd.

Trial test was conducted by running 2 trains, fixed with most advanced and modified TCAS equipment, in opposite directions over the same track at the speed of 60 kmph and a train from behind into a stationary one between Navandgi and Mantatti stations.

The two trains stopped at about 200 meters distance between them as officials observed the trial with bated gasp. Smiles broke out as the effectiveness of this new technology was proved excellent in the test run. Interestingly, the senior officials of railway were seated in moving train that approached the standing train, one from behind.

Mittal said it is a path-breaking technology and they would complete all trials totally in a year. TCAS has more abilities than the other technologies, which are at present used in advanced countries. He said he is happy that the trial was completely successful. Mr. Ramachandran said that the technology having some partial options would be announced in few sections within 6 months.

Sources said that TCAS not only would help to avoid collisions that are caused due to errors in invisibility of signal due to fog or heavy rain and errors in signalling, but also alerts about sudden fire on train and cautions about damage caused in the tracks during sabotage or natural calamities.
