L&T Begins TBM Shakti’s Assembly for Rishikesh – Karnaprayag Rail

Larsen & Toubro this week began assembling parts of tunnel boring machine TBM Shakti (S-1309A) for the 125 km Rishikesh-Karnaprayag railway line project’s Package 4.

This new railway line by RVNL will link both towns in Uttarakhand through 12 stations. L&T was awarded a Rs. 3337.60 crore contract for Package 4 in January 2021 to build the section from chainage 47.360 to 63.118.

Package 4 includes 14.577-km up-line and 13.123-km down-line tunnels, out of which 10.490 km and 10.317 km will be constructed using 2 Herrenknecht Hard Rock machines (TBM Shakti & TBM Shiv) with diameters of 9.1 meters.

TBM Shakti had passed factory acceptance tests (FAT) in Germany in February (see images) and arrived on-site in August-end (see images)

TUMAS India Pvt. Ltd. – Altinok Musavirlik Muhenislik A.S (JV) is Package 4’s detailed design consultant (DDC).

L&T is chasing a 60 month completion deadline. Per their old press release, this will be the biggest TBM to be deployed in the Himalayan region, and the TBM bored tunnel length of 20.807 km will be the longest for any project in the Himalayan region.
