Bengaluru Metro Project Update: From Wednesday, the tunnel boring machine (TBM)- Urja of Bengaluru Metro will start tunnelling the stretch between Cantonment and Pottery Town metro stations, covering a distance of 907 metre, said officials from Bangalore Metro Rail Corporation Limited (BMRCL). In the month of September this year, TBM Urja achieved a breakthrough after tunnelling between Cantonment and Shivajinagar in the Karnataka capital.

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