The derailment happened after an error in the electronic signalling system that led a train to wrongly change tracks, India s railways minister said on Sunday.
A devastating crash involving three trains in the eastern Indian state of Odisha has killed nearly 300 people and left hundreds injured, many of them seriously. Railway Minister Ashwini Vaishnaw, who has been at the site of the accident, has said "a high-level committee" will be set up to investigate the accident.
