evidence: As the accident happened, the Howrah Superfast Express was passing in the opposite direction at 126km/h (78mph). Coaches from the derailing Coromandel Express collided with rear two coaches of the Howrah Superfast, knocking them off the track. [...] India rail expert Rajendra Aklekar said the driver of the Coromandel Express would have had "absolutely no response time to halt the train" as it all happened in a matter of seconds. [...] "Some of the coaches of the Coromandel Express had gone over the goods train," Mr Biswas said. "There were lots of injured people and bodies here. I met a young boy who had lost both his parents. He was crying and then he died too."
