Shifting of rail assets for bullet train project beginsBy Anand Singh (IANS) At least seven Indian companies have shown interest for the construction of the undersea tunnel for the ambitious Mumbai-Ahmedabad High Speed Rail (MAHSR) corridor during the pre-bidding stage, officials said on Sunday.

A National High Speed Rail Corporation Limited (NHSRCL) official told IANS, “Seven Indian companies had participated in pre bid meeting for constructing the undersea tunnel of the corridor.”

The official said that the tender for the construction of the tunnel has been floated and bids are invited till February 19, 2021.

The bullet train project will have a 21 km long underground corridor from BKC to Kalyan Shilphata in the state of Maharashtra.

The official said that around 7 km of this underground corridor is under the Thane creek. Of this, 1.8 km long section will be developed under the sea bed, while the remaining part of the stretch is to be built under the mangroves marshland on either side of the creek.

The official said that tender is for the development of tunnel, which includes testing as well as commissioning for double-line high speed railway for the project using tunnel boring machine (TBM) and a new Austrian tunnelling method (NATM).

A geo-technical investigation of the undersea tunnel area was carried out earlier by a team of engineers from NHSRCL, RITES and Japan’s Kawasaki Geological Engineering firm.

In order to study the sea bed structure, a static refraction technique (SRT) survey was carried out by the team, which involved firing a high energy sound wave towards the seabed from below the water surface as well as mapping the refracted sound wave in order to determine the density of the rock under the sea bed. The team had also submitted the final report with the NHSRCL.

The bullet trains are expected to run at 350 km per hour, covering the 508-km stretch in about two hours. Trains plying on the route take over seven hours and planes about an hour.

Prime Ministers Narendra Modi and then Japanese Prime Minister Shinzo Abe on September 14, 2017 laid the foundation stone for the Rs 1.08 lakh crore ($17 billion) HSR project.
