The Bengaluru Metro Blue Line has finished a 6-km trial run from Byappanahalli to Doddanekundi, bringing the 58.19-km corridor closer to connecting Kempegowda International Airport with Central Silk Board.

The line will travel through major IT hubs – HSR Layout, Bellandur, Marathahalli, K.R. Puram, Hebbal and Yelahanka – before reaching the airport. It will use modern driverless train technology. A 38.44-km stretch runs from K.R. Puram to the airport while a 19.75-km section connects K.R. Puram to Central Silk Board.

Commercial operations are planned in phases between 2027 and March 2028. The Central Silk Board-K.R. Puram segment should open by mid-2027, and the Hebbal-Airport stretch is expected to finish by September 2027; no official opening date has been announced.

The trial tested electrical systems and rolling stock readiness at Byappanahalli depot. Testing will resume next week after Deepavali, pending worker availability. Bharat Earth Movers Limited (BEML) supplied the driverless trainset that powers the line.
