Was the fail-safe signalling mechanism around Bahanaga Bazar station where the deadly accident occurred over-ridden manually and tweaked during work at the level crossing gate near the station to avoid the detention and delay of speeding Coromandel Express?

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.
