The collision flipped Coromandel Express's coaches onto another track, causing the incoming Yesvantpur-Howrah Express from the opposite side also to derail, she said.
Authorities worked to clear the mangled wreckage of the two passenger trains that derailed Friday night in one of the country’s deadliest rail disasters in decades.
The derailment in eastern India that killed 275 people and injured hundreds was caused by an error in the electronic signaling system that led a train to wrongly change tracks and crash into a freight train, officials said Sunday.
