Sydney Metro Enters Final Commissioning Phase for Sydenham to Bankstown Conversion as Western Sydney Airport Countdown Begins

Transforming a Century-Old Rail Corridor into Rapid Transit

SYDNEY, New South Wales — Australia’s most extensive public transit transformation has reached its pivotal final phase as Sydney Metro engineering teams conduct integrated systems trials, automated train testing, and safety commissioning across the Sydenham to Bankstown section of the M1 City & Southwest line. The generational infrastructure project successfully converts a century-old 13-kilometre section of the historic T3 heavy rail line into an ultra-modern, fully automated rapid transit corridor.

The comprehensive overhaul upgrades ten suburban stations—including Marrickville, Dulwich Hill, Campsie, and Bankstown—with platform screen doors, level boarding access, new pedestrian overpasses, and modernized wayfinding. Once opened for passenger revenue service, driverless trains will arrive every four minutes during peak travel windows, whisking commuters directly through central Sydney, Barangaroo, and across the harbor to Chatswood without transferring.

Countdown to Western Sydney International Airport Opening

The rapid transit commissioning coincides with intense statewide excitement as New South Wales and federal transport authorities enter the final countdown toward the opening of Western Sydney International (Nancy-Bird Walton) Airport (WSI), scheduled to welcome its first passenger flights on October 25, 2026. Located at Badgerys Creek, the 24/7 curfew-free global gateway is set to serve up to 10 million passengers annually in its initial phase, supported by a state-of-the-art 3.7-kilometer CAT III-B instrument landing runway.

The opening of WSI anchors the development of the Bradfield City Centre, Australia's first purpose-built 22nd-century cyber-physical smart city, poised to become a thriving epicenter for advanced manufacturing, aerospace engineering, and green technology research.

Building the Sydney Metro – Western Sydney Airport Rail Link

To guarantee long-term multi-modal connectivity for the new aviation hub, construction is progressing rapidly on the dedicated Sydney Metro – Western Sydney Airport line. Spanning 23 kilometers with six new stations connecting St Marys on the suburban rail network directly to the airport terminal and Bradfield, tunneling teams have completed major excavation work while station fit-outs and traction power installations advance ahead of expected completion in 2027.

Transport authorities confirmed that high-frequency express bus feeder routes and newly upgraded arterial motorways—including the M12 Motorway—will provide seamless passenger connectivity from the airport's very first day of flight operations.

Catalyzing Long-Term Economic Prosperity Across Greater Sydney

New South Wales leadership noted that harmonizing automated metro rail expansion with world-class aviation infrastructure represents the backbone of the state's economic strategy. By delivering turn-up-and-go public transit and establishing a premier 24/7 aerotropolis, Sydney is solidifying its position as the premier business, tourism, and innovation capital of the southern hemisphere.
