In railways, any failure of signal or system leads to a fail-safe mechanism for public safety, which means all signals around any failure turn red and all trains come to a halt where they are. Sources said that in case of the deadly Odisha accident, railways are investigating if there was some possibility of someone over-riding the fail-safe mechanism and ‘criminal negligence’ to allow the train to pass.
