Train Protection Warning System (TPWS), European system for Indian rails (Modified AWS)


LUDHIANA: Based on the track system in European countries, the railway authorities in India are ready to install train protection warning system (TPWS) here to avoid collisions between trains and reduce accident rates.The authorities have handed over the responsibility to European Railway Train Management Company to conduct trials at Palwal section in Delhi division.

Following the successful trial at Chennai Central section in 2008, the authorities have decided to implement it in northern and north central railways.

Sources revealed that TPWS is actually further modification of auxiliary warning system (AWS). Primarily aimed to minimise the risk of trains jumping signals at danger points, it is presently used to reduce collisions with buffer stops and over-speed derailment risks. The device automatically applies brake on a train if it approaches danger.

This wireless system would also help the driver to maintain the speed as authorities are mulling over the idea of trains running on increased speed, sources added.

Giving information, senior divisional safety officer RV Singh said they were working on the installation of the system in Ferozepur division. Electrification of the railway tracks, which is one of the prerequisites, is on.

“The system sends a beep signal to the driver if there is some obstruction on the track and allows him sufficient time to stop the train. It also applies automatic brakes if need be,” he added.

In the past few months, several accidents have occurred on tracks, claiming many lives of commuters.
