The 800-metre-long railway bridge over the Chakki river in Pathankot on the border of Punjab and Himachal Pradesh collapsed after a flash flood washed away a bridge pillar.
The narrow-gauge train service between Pathankot and Jogindernagar, commissioned by the British in 1928, was stopped last month after the bridge developed cracks. Now the pillar was washed away.
