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)
