construction of tunnel is not more than 90 days work. TBM machine can do it. Indian railway has to construct only 380 m tunnel. it is one of the shortest tunnel of indian Railway.Min speed of TBM is 10m to 90m per day.
So it is a very easy task for contractor. I request Indian railway and all literate community to spread the real fact of tunnel to control corruption and loot in the name of Tunnel.It is already too much delayed.
