Udaipur Ahmadabad railway track project – 840 meter Kharwa tunnel will take 2 years to construct

As the gauge conversion work on the Udaipur-Ahmadabad rail route progresses, the work on the Kharwa Chanda tunnel will proceed simultaneously, but will take 18-24 months to complete.

Designed on the lines of Chirva tunnel, work on this 840 meter long Kharwa-Chanda tunnel has begun, expected to be completed within 2 years.  The 25 sq meter portal work (slicing the two ends of the tunnel) has begin under the supervision of Railway engineers. The tunnel, which is approximately 1,380 feet above sea level, is adjacent to the old meter gauge line tunnel, which was 259 meter long.  Each end of the tunnel (portal) will be 5 meter by 5 meters.  The tunnel will be squeezed through a 125 ft high hill. Once an optimal height is available, the base will be prepared, which will assist in the tunnel digging.

The distance between Kharwa and Zawar Mines is 15km.  The tunnel is 142 km away from Det.  A 4mtr x 4mtr refuge will be dug into the inner walls of the tunnel every 100 meters, for the protection of railway workers.  Workers can use this refuge when a train passes through the tunnel.
