Trains are running again on the tracks in Odisha state where a huge train crash happened on Friday, killing near to 300 people.

India's railways ministry has said the three-train collision was caused by an error in electronic signal that sent a train on to the wrong tracks. Investigations are underway into the cause of the signal fault.

Sudhanshu Mani, a retired mechanical engineer who was the General Manager of Indian Railways and the mastermind behind the country's first modern high-speed train told Newsday "interlocking failure" or a signal fault '"can only happen by some manual tampering" and that can be because of "criminal intent to cause death" or "criminal neglect by maintenance staff". The inquiry has gone to India's criminal bureau of investigation.
