The fire broke out in the B1 three-tier AC coach and spread to the adjoining coach. Fire engines and ambulances were rushed to the spot.
Rescue workers retrieved the bodies, which were burnt beyond recognition. The bodies were being shifted to Bangalore, where DNA tests would be conducted on them to establish the identity of victims.
