Fog delayed twice the number of trains this winter
As many as 12,700 trains were delayed due to fog this winter, Minister of State for Railways Rajen Gohain announced on Saturday. This was nearly double when compared to previous year, Gohain said while addressing the Rajya Sabha. He added that "modified automatic signalling" and over 6,700 GPS-based fog safety devices had been introduced to prevent delays due to fog.
