Rattled by a spate of train accidents, the railways have stepped up moves to install Train Protection Warning System (TPWS) across different zonal railways.
Detailed estimates for installing the TPWS on the Eastern, South Eastern and North Central Railways are ready and commercial trials will start soon, a ministry official informed.
The TPWS is a computer-based system that picks up data regarding signal from a ground-based box. This information is processed by the computer and speed indication including braking command is given to the driver. If the driver is not able to follow, auto braking takes place.
As at the July 19 accident at Sainthia, many accidents in past few months have occurred between trains running on the same track.
The Railway Board has also sanctioned trials on the improved version of Anti Collision Devices (ACDs) in the southern region. Since July 2006, the ACDs are being tested as a pilot project on the 1,736 route kilometres of the North Frontier Railway (NFR).
The Konkan Railway Corporation Limited — that developed the ACDs — have been asked to commence trials in the Southern, South Central and South Western Railways and submit updated cost estimates.
