New Delhi, March 26 (IANS) A railway commission Monday recommended a review of all coach designs to facilitate exits in case of fire or other emergencies and vestibule connection following last month's Samjhauta Express link train mishap.

The commission of railway safety, northern circle-New Delhi, released a report on the explosion and fire in the coaches of 4001 Up Attari Special - the India-Pakistan train popularly known as the Samjhauta Express - near Diwana railway station, killing 68 people Feb 18.

The report stated: "Based on the evidence available so far, the commissioner has come to the tentative conclusion that the fire in 4001 Up Attari Special was caused because of the explosion of bombs kept on the upper racks near the doorways in coach numbers GS 03431 and GS 14857 of this train."

The commissioner has also suggested providing for vestibule connection between coaches to help passengers move from one coach to another.

Another recommendation is that there should be strict baggage checks at the Delhi railway station "as is done at Attari railway station since the train, after starting from Delhi, stops only at Attari and is received on a platform that is a protected area and from where the passengers are required to undergo immigration and customs checks and then board the Samjhauta Express".

The commissioner has also recommended that identification of unclaimed or suspicious baggage should be undertaken in all the trains for safe travel of passengers.
