BENGALURU (Metro Rail News): Bangalore Metro Rail Corporation Limited (BMRCL) has started trial runs on the Blue Line’s Outer Ring Road (ORR) corridor, running a test train over about 6 km of the mainline viaduct between the Baiyappanahalli depot and Doddanekundi station on 10 November 2026. The route passes through KR Puram.
Bengaluru Development Minister Krishna Byre Gowda said the 58.19-km Blue Line, which will connect Central Silk Board with Kempegowda International Airport via KR Puram and Hebbal, has moved a step closer to mainline testing.
“Our government is committed to completing all pending works and ensuring the Blue Line is opened to the public at the earliest, strengthening Bengaluru’s connectivity and transforming urban mobility,” Gowda said in a post on X.
Marathahalli Target and Pending Work
BMRCL aims to extend the trial runs from the depot via KR Puram to Marathahalli by 15 November. The 33 kV cables and third rail between the depot and Marathahalli have been charged in stages since 30 October.

Signalling integration is the main item left before full testing can begin. About 2 km of track installation and some station work also remain on the corridor, according to reports. In August, the Railway Board gave in-principle approval for CBTC signalling on the Blue and Pink lines.
Opening Timeline
Reports put the opening of the 19.75-km Phase 2A section between Central Silk Board and KR Puram in mid-2027. In August, Gowda moved the target for the full Blue Line to the airport to March 2028, from December 2027, citing pending work at Marathahalli, Silk Board and Hebbal.
The trials come days before Prime Minister Narendra Modi inaugurates the Pink Line’s elevated Kalena Agrahara-Tavarekere stretch on 13 November, which will take Bengaluru’s operational metro network to 103.6 km.
