A forensic investigation will be conducted into cause of the fire which broke out in two coaches of the Dehradun-bound Doon Express near Gomoh in Jharkhand on Tuesday, that left seven passengers charred to death.
A Jharkhand state forensic team from Ranchi will visit Gomoh tomorrow to examine the coaches, Railway sources said.
The forensic investigation will be held in addition to the routine investigation into the accident by the Commissioner for Railway Safety, Eastern Circle, they said.
According to the sources, the fire could have spread further but for the alertness of a Permanent Way Inspector, in Gomoh, R K Pal, who alerted the engineering control room there after seeing the two burning coaches.
The control room alerted the train's driver B D Singh, assistant driver A Ansari and guard A K Khan. The train was stopped immediately and the three braved scorching heat to detach the affected coaches from the rest of the train, they said.
While the railways had made arrangements for passengers of the two coaches to continue their onward journey, 11 others who wanted to return were brought to Howrah by the Dehradun-Howrah Express.
