Uttarakhand (Metro Rail News): Herrenknecht AG conducted factory acceptance tests (FAT) on Larsen & Toubro’s first tunnel boring machine, TBM Shakti (S1310), on Tuesday for Package 4 of the 125 KM Rishikesh-Karnaprayag railway line project.

RVNL’s new railway line will run through 12 stations and connect both towns in Uttarakhand. In January 2021, L&T was granted an Rs. 3337.60 crore contract for Package 4 to construct the section between chainage 47.360 and 63.118.

Package 4 has 14.577 kilometres of up-line and 13.123 kilometres of down-line tunnels, of which 10.490 kilometres and 10.317 kilometres will be built utilising two Herrenknecht Hard Rock TBMs with 9.1-metre diameters. In addition, a 240m embankment at Devprayag Station, a 300m embankment at Janasu, and one minor bridge are also included in the scope.

L&T is aiming for a 60-month completion timeframe. According to their previous press release, this will be the biggest TBM ever deployed in the Himalayan region, with TBM bored tunnel length of 20.807 km, the longest for any project in the Himalayan region. Herrenknecht finished factory testing on L&T’s first TBM (Marsu) for the 1000 MW Pakal Dul Hydroelectric Project in Jammu & Kashmir in January.
