The fire broke out at around 4.30 am in the pantry car and soon engulfed the whole bogie. Fire tenders and local people fought for two hours to douse the flames before the train was brought to Dharamtul station.
After the burnt pantry car was detached, the train made its onward journey to New Delhi from Guwahati around noon, Lahiri said.
The cause of the fire was yet to be ascertained. Trains on the single line Guwahati-Lumding railway track were stopped for three hours till it was cleared at 8 am.
The train originated from Dibrugarh on 8.30 pm last night and was scheduled to arrive at Guwahati at 6.40 am.
