Railways testing fog-fighting technology, delays expected

DELHI: It’s approaching fog time again, threatening severe disruption of train services as is usual every winter, causing much inconvenience to passengers.

However, the railways’ fog-preparedness still seems to inadequate as the much talked-about LED fog lights and other technology in locomotives of north-bound trains — aimed at increasing visibility for train drivers in adverse weather conditions — is still in the trial stage, reports IANS.

All north-bound trains get delayed for hours due to poor visibility during foggy weather, causing a ripple effect on the congested network. The dense fog forces drivers to slow down train speeds up to 15 kmph as a safety requirement — resulting in delays ranging between four and 22 hours.

Rattled by the massive disruption in services year after year in winter, the railways has initiated several steps to use technology to fight fog.

The steps include a Train Protection Warning System (TPWS), a Train Collision Avoidance System (TCAS), and a Terrain Imaging for Diesel Drivers (Tri-NETRA) System, with the latest one being LED fog lights to improve visibility so that drivers can maintain normal speeds.

However, while these tech-tools are still being tried, the use of the tried-and-tested crackers is still in vogue during fog.
