J Kumar’s Surat Metro TBMs S25 & S28 Pass Factory Tests

J Kumar Infraprojects last week completed factory acceptance tests (FAT) on two tunnel boring machines for Surat Metro Phase 1’s 3.56 km underground Package CS3 between Surat Railway Station and Chowk Bazar Ramp.

These Ø 6.61m Terratec earth pressure balance machines – S25 and S28 – had previously seen action in Delhi Metro’s Phase 3 where they built Package CC-24’s tunnels between Hazrat Nizamuddin and Lajpat Nagar.

Following a final double breakthrough at Vinobhapuri Station in November 2016, they were stored in Mundka on the outskirts of Delhi, and then brought to Surat’s Palanpur in April 2021 for extensive refurbishment.

Restoration and assembly in progress earlier this summer

J Kumar Infraprojects was awarded Package CS3’s Rs. 941.80 crore contract by Gujarat Metro Rail Corporation (GMRC) in December 2020.

Their scope includes constructing the 21.61 km Line-1’s underground section from chainage 7160.6m to chainage 10720m with 3 stations at Chowk Bazar, Maskati Hospital and Surat Railway Station.

    Hey TMRG

    Not related to this post, but I read that BMRCL has retained the contract with CRRC for Namma metro coaches. It seems they will be built by Titagarh Wagon LTD – https://www.newindianexpress.com/cities/bengaluru/2022/jul/21/chinese-firm-retains-contract-for-216-namma-metro-coaches-2478954.html

    Do you have any inputs on this news?

    • TMRG says:

      Hi – too much time’s been lost; just hope this is the real deal. If Titagarh is setting up a new plant instead of utilizing their existing one, as the link suggests, then we’ll now likely see the first locally built train-set deployed no sooner than mid 2024.
