Bengaluru Namma Metro Pink Line Update: With Namma Metro’s Yellow Line operational since August, Bengaluru’s focus now shifts to the Pink Line. The Bangalore Metro Rail Corporation Limited (BMRCL) has confirmed that the 21.3-km corridor will open in two phases by 2026. The elevated section from Tavarekere to Kalena Agrahara, along Bannerghatta Road, is expected to start operations by March 2026. The 13.76-km underground stretch, connecting Dairy Circle to Nagawara via M.G. Road, Shivajinagar, and Tannery Road, is slated for September 2026.

Bengaluru Metro Pink Line: Construction And Testing Updates

According to The Hindu report, Civil work for the elevated segment is complete, while station construction continues in the underground section. Track installation and system integration are ongoing across both stretches. In June, BMRCL carried out “third rail” testing on the elevated line between Jayadeva and Tavarekere. Officials said this is the first step in safety trials, followed by signalling, telecom checks and load testing.

Bengaluru Namma Metro Pink Line: Challenges And Delays

The Pink Line has faced multiple delays. Initially promised in 2020, it was later rescheduled for December 2025. Officials cited Bengaluru’s tough subsoil as the main challenge. Tunnelling machines had to cut through hard granite and dense dolerite boulders, making progress slow, particularly in densely populated areas. The 2.2-km Shivajinagar–Vellara Junction tunnel was the most difficult section and contributed to repeated postponements.

Bengaluru News: Tunnelling Milestone

Despite obstacles, BMRCL completed tunnelling across the underground section in October 2024. Although the corridor is 14 km long, twin tunnels were carved out, resulting in a total tunnelling length of 21 km to allow trains to operate in both directions.

Namma Metro Pink Line: Phase 2 Connectivity

The Pink Line will provide a critical north–south link in Phase 2 of Namma Metro, connecting Kalena Agrahara in the south to Nagawara in the north. The elevated 7.5-km section and the 13.8-km underground stretch will improve connectivity to central business hubs and residential areas, easing travel for commuters across the city.
