The cause of India's devastating train accident, which killed at least 288 people, has been identified, as well as those responsible for it, India's railway minister said on Sunday.
India's Railway Minister Ashwini Vaishnaw said the country's worst train crash in decades was owed to the "change that occurred during electronic interlocking." The technical term refers to a complex signal system that arranges the movement of trains on the track to prevent them from colliding.
Ashwini added that it was "not appropriate" to give more details on the causes of the crash before a final investigation report.
