The tunnel boring machine (TBM) named 'Vamika,' operating on the Kalenagrahara-Nagwara ‘Pink’ line (21.30 km) of the Bengaluru Metro, has successfully excavated a 721-meter metro tunnel. A substantial portion of the total route, containing 20 km, has seen notable progress, with 17.62 km of tunnelling process being completed.
The Bengaluru Metro Railway Corporation (BMRCL) revealed that 'Vamika' initiated its tunneling activities from Lakkasandra Metro Station on August 21st, and recently emerged at Langford Town Station in Bengaluru.
Previously, 'Vamika TBM' accomplished a tunnel length of 613.2 meters between the South ramp and Dairy Circle tunnel stations, as well as 743.4 meters between Dairy Circle Station and Lakkasandra Station. Of the 9 TBM machines deployed for the tunnelling operations, 6 TBMs have successfully concluded their tasks, stated BMRCL.
The pending tunneling work includes 'Rudra TBM,' covering 613.20 meters from the South ramp to Dairy Circle, and 746.2 meters from Dairy Circle to Lakkasandra. This TBM is also actively carving a tunnel of a 633.2-meter stretch from Lakkasandra to Langford Town, with 87 meters remaining. This work is expected to be completed by December. Moreover, 'Tunga TMB' is operating over 838.8 meters near Venkateshpur-Kadugondanahalli, while Bhadra TBM has 406 meters of tunnelling pending.
