The devastating fire Thursday morning on the Mumbai-Amritsar Frontier Mail may have been caused by a kerosene stove burst.
Member, Railway Safety Board, H C Gupta, said a preliminary examination of the burnt coaches has revealed pieces of a stove.
Thirty-eight people were killed when three coaches of the train caught fire near Ladhowal, 10 km from Ludhiana, at around 0600 IST.
Gupta told reporters that forensic experts examined the burnt coaches for two possibilities - electric short circuit and external reasons - and found pieces of a stove in S-4
