Afcons Infrastructure on Friday commissioned their second tunnel boring machine, S-1259, at Dairy Circle Ramp to build Bangalore Metro’s 21.386 km Pink Line (Reach 6) which will connect Nagawara – Kalena Agrahara via 18 stations.
In March, Afcons team started lowering its parts into the ramp’s TBM launch shaft area for constructing twin tunnels for the Pink Line’s 3.655 km Package RT-01 (Rashtriya Military School Station – Dairy Circle Ramp).
Per the tunneling plan, S-1259 will build 3 tunnels totaling 2075.306 meters for the north-bound tunnel from Dairy Circle Ramp to Langford Town Station:
- Dairy Circle Ramp to Dairy Circle Station: 613.458 meters (estimate of 260 days)
- Dairy Circle Station to Lakkasandra Station (formerly Mico Industries): 747.338 meters (estimate of 243 days)
- Lakkasandra Station to Langford Town Station: 714.510 meters (estimate of 157 days)

A total of 9 TBMs will be deployed by Afcons (3), Larsen & Toubro (4) and ITD Cementation (2) for constructing the city’s Pink Line. With this development – 6 of those have been commissioned.
Here’s a status of each with figures displayed from BMRCL’s March newsletter. Whenever the April newsletter is out (its timing is erratic), I’ll update this table.
