When the station master SB Mohanty changed the signal, it took 14 seconds to change it but it was done instantly. According to experts, this was unusual. The station master should have noticed this. It was a false feed of the electronic interlocking system. Because the ground position of the track cannot be changed suddenly. Normally, whenever the station master changes the signal, he remains there until the change within 14 seconds. Had Mohanty caught this mistake, he would not have let the Coromandel Express go and the accident would have been avoided.
