If you have ever dreamt of traversing through the deep waters in a submarine, your dream can come true right here in India soon, but with a twist. In a first, India is all set to get its first-ever underwater train station in Kolkata!

Hooghly River’s underwater tunnel by the Kolkata Metro Rail Corporation (KMRC) is likely to be operational by the first half of next year, and will take you through the depths of the river. As per the report, KMRC has extended its East-West corridor, which would span the Hooghly River to incorporate a pair of unwater tunnels.

At 1.4 metres wide and 33 metres deep in the river water, the twin tunnels are about 500 metres long, 80 per cent work on which has already been completed. In order to prevent water from entering the tunnels, these have been equipped with hydrophilic gaskets.

 If reports are to be believed, while submerged, the train will be travelling at a depth equivalent to a 10-storey building! The one-of-a-kind project is being compared to the Eurostar corridor that connects the cities of London and Paris. The project is costed at about INR8,600 crore and is likely to become operational by March 2023. It will be the deepest station in the nation.

Four additional underground stations at Esplanade, Mahakaran, Howrah, and Howrah Maidan would be added to the railway journey. As of now, with a depth of 29 metres, Hauz Khas in the Delhi Metro is currently the deepest.

Additionally, there will be exits in the tunnel for emergencies like earthquakes. Between the stations of Mahakaran and Howrah, the tunnel will cross the river in less than a minute. India’s very own version of the popular Eurostar will drastically cut down on journey time, while offering fascinating underwater views!
