Railways goes for tech solution to replace guard vans in goods trains

NEW DELHI: Indian Railways is installing End of Train Telemetry (EoTT) equipment in goods trains, a new system to do away with the guard vans and the practice of deploying guards at the rear end of such trains. This will also ensure all wagons remain intact when the train is moving.
This device is used to establish communication between the locomotive driver and the last wagon of the train to ensure that the train is running with all coaches and wagons as a complete unit.
The procurement of these devices would cost around Rs 100 crore. Sources said the national transporter is procuring 10 such devices from the USA and South Africa next month for trial purposes. The technology has been successful in other countries.
The railways had started planning this upgrade three years back. The railways will purchase 1,000 such devices from abroad. The Banaras Locomotive Works (BLW) at Varanasi has ordered 250 EoTT from South Africa. In the next phase, 740 more such EoTT devices will be purchased.
Currently, the railways operates around 7,000 goods trains on its network and nearly 16,000 guards are engaged for this purpose.
Sources said the technology is cost effective as it replaces the requirement of a guard van. EoTT equipment is designed to do the guard’s job by giving indication to the loco driver in case of parting of wagon or coach from the rear side of the train. The EoTT system comprises two units; one unit called cab display unit (CDU) fitted on the locomotive and the other is sense and brake unit (SBU) fitted on the last coach or wagon of the train.
A transmitter is fitted on a locomotive and a receiver is fitted at the end of the last wagon. The transmitter and the last wagon receiver exchange signals periodically to ensure that the train is running intact. In case there is a break in the communication between the two units, the driver gets a signal that the train has parted and accordingly the train has to be stopped to re-link the parted wagons.
