The official said that the tender has been invited for the construction of the tunnel and bids have been invited till February 19, 2021. The bullet train project will have a 21 km long underground corridor from BKC to Kalyan Shilpata in Maharashtra. The official said that about 7 km of this underground corridor is under Thane Creek. Of this, a 1.8 km long section is to be developed below sea level, while the rest is to be built on the mangrove marshland on either side of the creek.

This contract is for tunnel construction

The official said the contract is for the tunnel, which includes testing as well as the construction of a double-line high speed railway for the project using the tunnel boring machine (TBM) and a new Austrian tunneling method (NATM). A team from NHSRCL, RITES and Japan’s Kawasaki Geological Engineering firm conducted a geotechnical investigation to build the tunnel under the sea.

Speed ​​will be 350 km

The bullet train is expected to run at a speed of 350 kilometers per hour, which will cover a distance of 508 kilometers in about two hours. Currently, the train takes seven hours for Mumbai-Ahmedabad and about one hour for the aircraft.
