Bengaluru’s much‑awaited Pink Line metro has entered a critical phase with the initiation of third‑rail testing on its elevated segment between Jayadeva and Tavarekere. This marks the beginning of essential technical trials ahead of the corridor’s eventual opening, bringing the network a step closer to completion.
BMRCL officials confirmed this first-stage evaluation is restricted to the elevated Kalena Agrahara–Nagawara section. A senior executive clarified that once third‑rail power trials conclude successfully, the focus will shift to signal system validations, telecom checks, and loading tests to verify structural resilience under operating conditions. These successive steps aim to ensure passenger safety and operational reliability. Originally slated for launch in 2020, the Pink Line—forming part of Phase 2 of the city’s Namma Metro—has seen multiple delays. The deadline was pushed to December 2025, but BMRCL has now outlined a revised schedule with phased commissioning entering service from March 2026 for the 7.5 km elevated section and September 2026 for the 13.8 km underground alignment.
Stretching over a total 21.3 km north‑south link from Kalena Agrahara on Bannerghatta Road to Nagawara on the Outer Ring Road, the line features 13.8 km of tunnels and 7.5 km of viaduct. Part of the elevated section tenders issued in 2017, its slow progress reflects engineering and logistical hurdles, notably in constructing the underground tunnels. BMRCL officials have cited challenging geology in Bengaluru—dense granite and dolerite boulders—as primary causes for underground delays. Particularly, the 2.2 km tunnel between Shivajinagar and Vellara Junction stalled construction due to hard rock conditions and urban constraints. A breakthrough came in October 2024, when tunnelling was officially completed. Including both bores, the total drilled length reached 21 km.
While elevated sections typically progress faster, third‑rail and signalling systems demand meticulous testing. The current phase involves energising the third‑rail infrastructure and conducting live power trials at low operational speeds. In parallel, teams will calibrate the train control and telecommunications networks—critical for synchronised operations once the system goes live. Once these systems are validated, structural loading trials will commence. These involve moving empty test trains of full passenger weight to evaluate clearances and stability. Only after these assessments will final safety audits and certification follow ahead of trial runs with commuters—a process that can take several weeks.
Commuters and businesses have expressed optimism over the Pink Line’s eventual launch, viewing it as a potential game‑changer for reducing traffic congestion and carbon emissions. Acting as a north‑south spine, it will link key arterial routes and crucial IT and commercial hubs across the city. Officials stress its importance in strengthening Bengaluru’s low‑carbon public transit framework—aligning with the broader agenda to build sustainable, eco‑friendly urban landscapes. However, past delays have triggered criticism from civic groups and commuters, lamenting the temporary inconvenience of prolonged construction. Some residents along the elevated corridor have reported increased dust, noise, and disruption. In response, BMRCL has promised enhanced monitoring and remedial measures during ongoing tests.
From a strategic perspective, the Pink Line advances the city’s metro coverage from the current 56% network length and integrates with the Purple, Blue, Green, and Yellow Lines. The addition of the Pink Line will bring the network’s total length to around 160 km upon full commissioning of Phase 2. As Bengaluru evolves into a connected metropolis, the real test will lie in ensuring these infrastructures withstand peak monsoon stress, technical wear and tear, and sustained commuter demand. Experts emphasise that while third‑rail testing is significant, consistent long‑term maintenance and community integration remain crucial to project success.
With third‑rail tests now underway, BMRCL is poised for a pivotal developmental milestone. Yet, the official launch remains contingent on the next rounds of comprehensive technical evaluations. For commuters, the Pink Line’s debut is still several months away—but the momentum behind its progress is unmistakable.
