Bengaluru Blue Line Metro trial runs begin, airport link by 2027
Synopsis
Bengaluru's most-awaited metro corridor just moved — literally. The 58.19-km Blue Line, linking ORR tech hubs to Kempegowda International Airport, began trial runs on Deepawali, with the first section targeting commercial launch by mid-2027. A 20–35% property surge along the corridor and driverless train tech add up to a moment that could reshape how Bengaluru commutes and grows.

Bengaluru's Namma Metro Blue Line — the 58.19-km Outer Ring Road-Airport Metro corridor connecting major IT hubs to Kempegowda International Airport — has commenced trial runs, marking a pivotal milestone in what is widely regarded as the city's most consequential infrastructure project in years. The development was confirmed on Wednesday, 11 November 2026, coinciding with Deepawali.
Trial Movement Under Way
Karnataka Minister for Bengaluru Development Krishna Byre Gowda confirmed the development via a post on social media platform X. 'Metro Blue Line train starts trial movement. During the last week, the train moved from the Bayyappanahalli test track to KR Pura and on to Doddanekkundi station. The trials will continue for some time,' he said.
The minister noted that construction work was still ongoing near Central Silk Board and that the initial trial was being conducted in a methodical, phased manner. Formal inspections are expected to begin soon and could take several months, he added.
Two Phases, One Corridor
The Blue Line is structured across two distinct phases. Phase-2A, the Outer Ring Road East Line, spans 19.75 km between Central Silk Board and KR Puram and covers 13 stations, including HSR Layout, Bellandur, and Marathahalli. Trial runs on this main line began in November 2026.
Phase-2B, the Airport Metro Line, extends 38.44 km from KR Puram to Kempegowda International Airport via Hebbal, with 16 main stations and provision for 3 future stations. Together, the corridor will pass through key employment belts including Marathahalli, Hebbal, and Yelahanka.
Commercial Operations Timeline
The Central Silk Board–KR Puram section is targeted for commercial launch by mid-2027, while the Hebbal–Airport stretch is expected to be ready by September 2027. The entire corridor, including the KR Puram–Hebbal and Nagawara sections, is projected to become fully operational by March 2028.
The line will introduce modern driverless train technology and luggage-friendly amenities specifically tailored for airport-bound travellers — a first for the Namma Metro network.
Economic and Real Estate Impact
Beyond easing commutes, the Blue Line is expected to catalyse significant economic activity along its corridor. Property and rental demand along the Outer Ring Road, Hebbal, and North Bengaluru belts is projected to surge by 20 to 35 per cent, according to analysts. The corridor directly serves Bengaluru's densest concentration of tech campuses, potentially reducing the city's notorious traffic load on the ORR stretch.
Notably, this comes as Bengaluru's metro footprint is set for a simultaneous boost: Prime Minister Narendra Modi is scheduled to inaugurate the Pink Line on 13 November. The elevated 7.5-km stretch between Kalena Agrahara and Tavarekere will push the city's total operational metro network beyond the 100-km mark to 103.6 km, officials confirmed.
Network Integration
The Blue Line will interlink with Bengaluru's existing and upcoming metro corridors — the Purple, Yellow, and Pink lines — significantly expanding the network's reach and interchange options. The integration is designed to reduce last-mile dependency and position Namma Metro as a credible daily commute solution for the city's estimated 13 million residents.
With inspections and further trial runs ahead, the full commercial launch of the Blue Line remains months away — but the trial movement signals that Bengaluru's airport metro dream is finally on track.
Point of View
But the real story is execution risk on a corridor that has repeatedly slipped its deadlines. The Central Silk Board–KR Puram section alone took years beyond original targets, and the airport stretch faces tougher civil engineering challenges. With formal inspections still months away and work near Central Silk Board incomplete, the mid-2027 commercial target looks optimistic at best. Bengaluru's IT workforce — which stands to benefit most — has heard this tune before; what matters now is whether the inspection and certification pipeline holds.
