Bengaluru Metro's Pink Line to be operational in two phases

In July 2024, BMRCL achieved a new milestone with 308 meters of tunnelling completed by Tunnel boring machine (TBM) Tunga between KG Halli and the Nagawara retrieval shaft by ITD. This surpassed the previous record of 273 meters by TBM Urja between Cantonment and Pottery Town in May 2022 by L&T.

Bengaluru Metro's Pink Line, which links Kalena Agrahara (Gottigere) on Bannerghatta Road in the south with Nagawara on Outer Ring Road in the north, will be operational in two phases, Moneycontrol has learnt.

A senior Bengaluru Metro Rail Corporation Limited (BMRCL) official told Moneycontrol, “The 7.5 km elevated section from Kalena Agrahara (Gottigere) to Tavarekere (Swagath Cross) will be operational by September 2025. The 13.8 km underground section, connecting Dairy Circle to Nagawara, will be ready by June 2026."

In August 2023, Bharat Earth Movers Limited (BEML) said it received rolling stock order worth Rs 3,177 crore from BMRCL to supply 318 coaches for Bengaluru Metro's Phase 2, Phase 2A, and Phase 2B corridors.

Tunnelling to be completed by October

BMRCL officials said that the entire tunnelling work will be completed by October 2024. "So far, 96.7% of the tunnelling work is done. We are hopeful to meet the deadline without major obstacles, though tunnelling in Bengaluru remains a challenging task," said a BMRCL official.

"Track work and station work are now progressing. Signalling, telecom and traction, Platform Screen Doors, and others will take more time," said another source.

The elevated section of Pink Line (Kalena Agrahara to Tavarekere) is being constructed by GR Infraprojects after BMRCL terminated the contract with the earlier firm, Simplex Constructions, in 2021 due to slow pace of work. L&T, ITD, and Afcons are entrusted with the construction of the city's longest underground Metro section between Dairy Circle and Nagawara.
