Urja, which has drilled a distance of 855 metre for over a year, is the first TBM to achieve a breakthrough on Namma Metro’s Pink Line from Kalenga Agrahara to Nagawara (21 km).

Bengaluru Metro’s tunnel boring machine (TBM) Urja will start tunnelling the stretch between Cantonment and Pottery Town stations, a distance of 907 metre, from Wednesday, said Bangalore Metro Rail Corporation Ltd (BMRCL) officials Tuesday.

Urja achieved a breakthrough after tunnelling between Cantonment and Shivajinagar in September this year. “It was transported and reassembled for its next journey,” officials added.

“Urja started laying the first tunnel ring on August 20, 2020 from Cantonment station and has successfully tunnelled up to Shivajinagar station under the most difficult geological conditions and below the oldest settlements of Bengaluru. Tunnelling using TBM is the most advanced PLC-based technology but the operation of such machines with high precision needs highly-skilled manpower and experts on the field,” officials had explained earlier.
