"The minister said the inquiry into the train accident has been completed and rail safety commissioner will submit the report at the earliest.
'The commissioner of railway safety has investigated...
more... the matter and let the investigation report come. But we have identified the cause of the incident and the people responsible for it... It happened due to a change in electronic interlocking. Right now our focus is on restoration,' the minister added.
According to Indian Railways, electronic Interlocking (EI) system is a microprocessor-based interlocking equipment to read the yard and panel inputs; process them in a fail-safe manner as per the selection table and generate the required output. This system is the alternative to the conventional Relay Interlocking system (PI & RRI), the ministry says."
