It appears, the motorman of the P35 Howrah-Panskura EMU local overshot the home signal — which clears trains for platforms — at Sankrail around 3.16 pm and risked the lives of hundreds.
While the motorman, identified as Khan, stopped his train on realizing the mistake, and applied emergency brakes on the Howrah-bound East Coast Express.
Angry passengers attacked the driver although he admitted his error. Train services remained suspended for three hours. Local railway officials rushed to the spot from Kharagpur and watched the mob fury from a distance.
Sankrail is located about 20km from Kolkata.
