India train disaster: signal fault blamed as wreckage cleared from track

Train was diverted on to wrong tracks, says railways minister as efforts to clear wreckage continue

India's railways minister has said the train derailment that killed at least 275 people and injured hundreds more was caused by an error in electronic signals that sent a train on to the wrong tracks.

Ashwini Vaishnaw's explanation on Sunday came as authorities worked to clear the mangled wreckage of two passenger trains that derailed on Friday night in eastern India, in one of the country's deadliest rail accidents in decades.
