Railway Safety Commissioner (North Eastern Circle) Bhupendra Singh, who probed the May 15 fire in the Golden Temple Mail (formerly known as Frontier Mail), has submitted his report to the government, official sources said in Delhi.

Thirty-eight people had died in their sleep when four coaches of the Amritsar-bound train caught fire, about 10km from Ludhiana in Punjab. The train originates in Mumbai.

Singh, who held a statutory enquiry into the unusual occurrence of fire in three coaches of the 2903 UP Golden Temple Mail, was not able to arrive at any conclusion as to how the fire started.

His report, however, states that the fire started from coach S-4, the sources said.

The statutory enquiry was held at Ludhiana from May 18-21, 2003 and thereafter from May 24-27 at New Delhi.
