The Patna Metro project is advancing rapidly, and the upcoming station near Patna Junction is set to become the most important hub in the entire network. As of February 2026, official reports confirm that this underground station will serve as the primary interchange point. This means passengers will use this spot to switch between Corridor 1 (Danapur to Khemnichak) and Corridor 2 (Patna Junction to New ISBT). Designed to manage heavy crowds, the station is expected to handle approximately 66,000 passengers every day once it is fully functional.
Three-Level Design and Station Features
To manage the high volume of daily commuters, the Patna Junction interchange station is being built with a unique three-level underground structure. This design ensures that passengers can move easily between lines without confusion. The station will connect to the network via three tunnels, one of which is already complete toward Akashvani.
- First Floor (Concourse): This upper level will house ticket counters, security checkpoints, and other passenger amenities.
- Second Floor: Located at a depth of 11-12 meters, this level will serve trains for Corridor 2 going towards New ISBT.
- Third Floor: The deepest level at 23-24 meters will have platforms for Corridor 1 trains running between Danapur and Khemnichak.
Construction Timeline and Opening Dates
While the underground work is complex, the authorities have set clear targets for completion. Two elevated stations, Khemnichak and Malahi Pakri, are currently in the final stages of safety reviews and are expected to open for the public in February 2026. For the massive underground section connecting Patna Junction, structural work is targeted to finish by late 2026.
Currently, utility test pits are being dug near Buddha Park to shift power and water lines before heavy excavation begins. The full Phase 1 operations are projected to start between 2027 and 2030, bringing a major relief to city traffic.
