India train disaster: signal fault identified as cause, says minister

India’s railways minister has said the country’s deadliest train crash in more than two decades was caused by an error in electronic signals that sent a train on to the wrong tracks. Ashwini Vaishnaw said the full investigation into Friday’s crash in the eastern state of Odisha, which killed at least 275 people and injured more than 1,000, was still under way but “the root cause has been identified”.
