Dense fog in Delhi; 36 trains delayed, 13 cancelled due to low visibility

NEW DELHI: As north India continues to reel under dense fog, train services remain disrupted in the national capital. As many as 36 Delhi-bound trains were on Saturday delayed and another 13 were cancelled.

In addition, at least two trains were rescheduled by the Indian Railways due to foggy weather.

North-western plains, including Punjab, Haryana, Delhi and West Uttar Pradesh, were covered under dense fog on Friday morning.

The train routes were affected due to low visibility and other operational reasons.

On Wednesday, the government had informed the Parliament that more than 3,000 trains were delayed due to fog between November 1 and December 21 in 2017.

In a written reply in the Lok Sabha, Railway Minister Piyush Goyal had said that 3,119 trains were delayed during the period on account of fog.

Goyal had said portable global positioning system (GPS)-based fog pass devices were being issued to the loco pilots for the regions which get seriously affected due to fog.

According to the data provided by the minister, the Northern Railways has received 3,185 of such devices, North Eastern Railways has got 975, North Western Railways 802, East Central Railways 617, North Central Railways 282 and the Northeast Frontier Railways has received 183.

"The reported outcome of the fog pass devices from the zonal railways has been satisfactory. The device provides a visual indication of the approaching level-crossing gates and other signal landmarks to the loco pilots, 500 metres in advance," Goyal had said.

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.

The Tri-NETRA system enables the driver to view the terrain on a computer installed in the cabin. However, all these systems are in the pilot stage. As for the LED fog lights, the Research Designs and Standards Organisation (RDSO) of the railways is currently finalising their specifications on these.

The railways expects that once these systems are installed, it will help in enhancing the vision of locomotive drivers in difficult weather conditions, such as fog, heavy rains and during the night time so that they have enough time to react to an emergency.
