Sydney Metro – Western Sydney Airport is the new metro railway line which will service Greater Western Sydney and the new Western Sydney International (Nancy-Bird Walton) Airport.

The railway will service the new airport and airport business park, the Western Sydney Aerotropolis, Luddenham, Orchard Hills and St Marys – here customers can connect to the existing Sydney Trains suburban T1 Western Line. The NSW and Australian governments have a shared objective of having Sydney Metro – Western Sydney Airport operational when the airport opens for passenger services.


Key features of the project

The project involves the construction and operation of a metro rail line, approx. 23 kilometres in length, between the T1 Western Line at St Marys in the north and the Aerotropolis Core in the south.

The project includes six new metro stations at:

  • St Marys, interchanging with the existing suburban railway station and connecting customers with the rest of Sydney’s rail system
  • Orchard Hills, to service a future commercial and mixed-use precinct
  • Luddenham, to service a future education, innovation and commercial precinct
  • two stations within the airport site, at the airport terminal and at the airport business park
  • the commercial heart of the Western Sydney Aerotropolis (the area proposed to be named Bradfield).

The alignment of the new metro railway line will:

  • include a combination of tunnel, surface, and viaduct sections
  • interface with key roads including the Great Western Highway, M4 Western Motorway, Luddenham Road, the future M12 Motorway, Badgerys Creek Road and Elizabeth Drive, as well as key utilities such as the Warragamba pipeline
  • include a stabling & maintenance facility at Orchard Hills and operational control centre
  • include intermediate service facilities at Claremont Meadows & Bringelly

Enabling works - site investigation, demolition works, utility relocations, utility supplies to sites, transport network adjustments, rail corridor works etc.
