Keeping the top most priority on the passenger safety, the Metro railway authorities have set up a walkway along the side of the railway track which will be extended up to the nearby stations.
A senior official of Metro railways said that if a train develops technical problems while travelling under the river bed, all the doors of that particular train will be thrown open on the side where the walkway is situated.
The height of the walkway is being constructed in keeping with the height of the door of the Metro rakes.As all the doors will be thrown open in case of any untoward incidents, passengers can easily walk along the way to the nearest railway station which will be communicated to them by theMetro staff members present in the train. People had a question in mind about how it is safe if a rake stops inside the tunnel under the river bed after developing a technical snag.
Railways officials said that passengers will not face any problems as they will get down to the walkway which will help them to reach to a nearby station. The Metro engineers were sure that ventilation which will be there inside the tunnel will help the passengers at the time of evacuation.
Once the commuters get onto the walkway, the Tunnel Ventilation System will do the trick, East-West Metro officials said.
The 14.67 km East-West Metro corridor will connect Howrah Maidan to Salt Lake Sector V.From Howrah Maidan the tunnel will cross over through underground tunnel set up about 10 meters deep under the Hooghly river bed and then it will get linked to Sealdah where the stretch coming from Salt Lake side will converge.
