Investigators were on Saturday looking into any human error, signal failure and other possible causes behind the three-train crash in Odisha's Balasore district as officials submitted a preliminary inquiry report into the worst rail accident in India in nearly three decades that left at least 288 people dead and over 1,100 injured.
Preliminary investigations have revealed that a signal was given to Coromandel Express to enter the main line but it was taken off and the train entered the loop line and crashed into a goods train parked there.
The crash involving Bengaluru-Howrah Superfast Express and Shalimar-Chennai Central Coromandel Express, which were carrying around 2,500 passengers, and a goods train occurred around 7 PM on Friday near the Bahanaga Bazar station in Balasore, about 250 km south of Kolkata and 170 km north of Bhubaneswar.
Twenty-one coaches were derailed and severely damaged in the accident, trapping hundreds of passengers. Both passenger trains were at a high speed and it has been cited by experts as one of the main reasons for the high number of casualties.
From a vantage point high above the ground, the disaster site looked as if a powerful whirlwind had thrown the coaches like toys on top of each other. Closer to the ground, bloodied, disfigured bodies and dismembered body parts lay enmeshed, creating a grotesque sight.
Large cranes were deployed to move the wreckage and gas cutters were used to extricate the bodies from the mangled, toppled coaches.
The rescue operation was wrapped up Saturday afternoon and restoration work started. With traffic on the route disrupted, over 150 trains were cancelled, diverted or short-terminated.
