"India's first underwater train will soon get started in Kolkata under the Hubli river. An example of impeccable engineering, this train is proof of the progress made by Indian Railways. This train will bring ease to the people of Kolkata and pride to the people of India." tweeted Piyush Goyal in Hindi.
The 16-kilometre long Kolkata Metro project will connect Salt Sector 5 with Howrah Maidan.
The phase I of the project connecting Salt Lake Sector-5 to Salt Lake Stadium will soon be operational.
The tunnel is provided with four-layers of protection to shield the tunnel from the water of Hubli river.
Goyal, last month, had said that there is "no question and no meaning" of privatising Railways, but the public-private partnership will be encouraged and there will be corporatisation of some units.
Replying to the debate on the demands for grants of his ministry, in which 99 members participated, Goyal outlined the plans of the government to boost safety and technology and said its performance has been far better compared to that of the UPA government.
