BANGALORE (Metro Rail News): The Tunnel Boring Machine (TBM), Bhadra, for the proposed Pink Line emerged at Shadi Mahal near Tannery Road on December 16 after tunnelling a distance of 1,066 metres. In June 2021, the machine was set up at Venkateshpura underground station to tunnel upward to K.G. Halli metro station.
According to Bangalore Metro Rail Corporation Limited (BMRCL) information, the machine finished the tunnel after 540 days. Tannery Road Station now features a 192-meter temporary tunnel for drive-through due to the machine.
The BMRCL is constructing a 14 km tunnel network from Dairy Circle to Nagawara as part of Phase II. The Namma Metro project’s contractors have operated nine tunnel boring machines. The line from Kalena Agrahara to Nagawara (Pink line) includes the tunnel system.
At Nagawara, this line will be integrated with the ORR airport line. The Pink Line is likely to be operational by 2024.
