Railway Minister Piyush Goyal today shared a video clip on the upcoming underwater metro rail project in Kolkata. The project is being constructed in the Hoogly river of Kolkata city.
The railway minister posted the clip and wrote in Hindi that the newly constructed underwater metro rail project is an perfect example of ‘exemplary engineering’ and also a sign of progress made by the Indian Railways.
The underwater tunnel is a crucial link for the railways’ 16.6-km long East-West Metro project in Kolkata.
The 520-metre twin tunnel, one east-bound and the other west-bound, is built 30 metre below the riverbed. Commuters between Howrah and Mahakaran metro stations will be under the river for only about a minute when the metro train will pass through the tunnel at a speed of 80 km per hour.
Of the 16.6-km route of the East-West Metro project, the tunneling covers 10.6 km, of which 520 metre is under the river.
The underwater tunnel is being built at a cost of Rs60 crore while the total cost of the East-West Metro project is estimated to be around Rs9,000 crore. The tunneling work started in April last year and likely to be completed in the river section shortly, a senior railway ministry official said.
For the railways, besides the tunnel under the Hooghly river, drilling work is going on for the seven-km-long under- sea route of the Mumbai-Ahmedabad rail corridor to ascertain soil condition for India’s first bullet train path.
Passengers will get the thrill of travelling under the sea at a maximum speed of 350 km/hour, another first in the country, near Thane in the upcoming high-speed train project connecting the two metropolis.
