Sydney Metro Western Sydney Airport, previously known asSydney Metro Greater West, is arapid transit rail project currently under-construction inGreater Western Sydney. The project involves the construction of a 23-kilometre (14 mi) line as part of theSydney Metro system.[3] The line will operate betweenSt Marys, where the line will connect to theMain Western railway line, andBradfield via theWestern Sydney Airport. It is intended to provide public transport for the upcoming Western Sydney Airport.[4] Construction of the line started in December 2022 and was expected to be completed in late 2026 in time for the opening of the airport. However, it has been reported that operations may not commence until April 2027.[5][6][7]
The line will have six stations.[3][8]
The line is to run via twin tunnels between St Marys and Orchard Hills stations and between the Airport Terminal and Bradfield stations. Tunnel boring machines are being used from Orchard Hills and the Airport Business Park.[8]
The line will form Stage 1 of a proposedNorth South Rail Line, which would see the line extended north toSchofields to connect to theRichmond railway line, and south to theMain Southern railway line atMacarthur.[9][10]
In 2014, the Federal Government under then Prime MinisterTony Abbott initially had no plans to build a rail line. However, it indicated provision for a railway line would be included in the development that may include preparing tunnels under the runway as part of the runway construction and preparing the underground space for a station. It was considered likely the rail connection to the airport would consist of an extension to theSouth West Rail Link fromLeppington.[11] In 2015, then Prime MinisterMalcolm Turnbull indicated that the airport would need both road and rail links to the Sydney CBD.[12] In November 2015, a scoping study into rail investment to service Western Sydney and the Western Sydney Airport was announced. The study was jointly managed by the NSW and the Commonwealth governments.[13] A discussion paper, released in September 2016, proposed various options that could provide a rail link to the airport, listed below:[14]
| Option | Mode |
|---|---|
| Extension of theSouth West Rail Link fromLeppington | Suburban rail |
| Line to theMetro North West & Bankstown Line atRouse Hill | Metro |
| Extension of theSydney Metro City & Southwest fromBankstown viaLiverpool | Metro |
| Line to theMain Western railway line atSt Marys | Suburban rail |
| New express line to the Sydney CBD viaParramatta | Metro |
| Line between Macarthur and Schofields via WSA and St Marys | Metro |
The final report, released in March 2018, proposed that two lines would ultimately service the airport: a "North-South Link" from Schofields to Macarthur and an "East-West Link" from Parramatta to the "Badgerys Creek Aerotropolis", an area south of the airport. The East-West Link would likely form an extension of the already-announcedSydney Metro West. An extension of the South West Rail Link to the Badgerys Creek Aerotropolis was also proposed. Interchanging with the North-South Link or East-West Link would be required to access the airport itself.[15]
Later in March 2018, the federal and state governments signed the Western Sydney City Deal and announced the development of stage 1 of the North South Rail Link as part of the deal.[16]
Between 2019 and May 2020, the stage 1 of the North-South Link is referred to as "Sydney Metro Greater West" by the Sydney Metro agency.[17] The project update on 1 June 2020 confirmed the name of the line to be "Sydney Metro – Western Sydney Airport".[18]
Prior to June 2020, the only stations proposed were atSt Marys,Western Sydney Airport and Aerotropolis. The proposed six stations of Stage 1 were confirmed in June 2020 and the exact locations of the stations were confirmed in September 2020.[18][19][20][8]
In October 2020, the project's Environmental Impact Statement (EIS) was released to the public for exhibition.[21] Since the work would be carried out within the airport boundary, federal planning approval was also required.[22] State planning approval was granted in July 2021, and federal planning approval was granted in September 2021.[23][22]
In the 2019-2020 federal budget in April 2019, the federal government announced a contribution of $3.5 billion to deliver stage 1 of the rail link.[24][25] This funding also includes $50 million towards the business case process for the North-South Rail Link and $61 million for the Elizabeth Drive overpass.
In the 2019–2020 New South Wales state budget in June 2019, the state government announced an investment of $2.0 billion to commence the construction of stage 1 for the next 4 years.[26]
In June 2020, the federal and state governments announced a further $3.5 billion contribution to push the construction date earlier to late 2020.[27] Designs were modified to include an additional six kilometres of tunnelling. As of June 2020, the project has a price tag ofA$11 billion.[19]
In March 2021, three consortia (Acciona, ajoint venture ofJohn Holland andGamuda,CPB andGhella) were shortlisted to deliver tunnelling works for the project.[28] The station box and tunnelling contract was awarded to CPB and Ghella in December 2021.[29] In September 2023, a tunnel boring machine, one of four tunnel boring machines, had completed the first 1.26 km section of its 5.5 km tunnel.[30] Tunnelling is expected to be complete in late 2024, with track laying and station fitout to occur afterwards.
A second major contract for surface and civil alignment works was awarded to CPB and United Infrastructure in March 2022.[31]
A third major contract was the Stations, Systems, Trains, Operations and Maintenance (SSTOM) package for the construction of the stations and operation of the line. In October 2021, three consortia were shortlisted:[32]
The SSTOM package was awarded to Parklife Metro in December 2022.[33]
As of late 2025, station platforms and buildings are currently under construction, with track laying in tunnels taking place at the same time.[34]
Being awarded the SSTOM package, Parklife Metro will operate and maintain the line for 15 years after it becomes operational.[33]
The Sydney Metro Trains Facility and the Operations Control Centre will be located at Orchard Hills, and services facilities will be located atClaremont Meadows andBringelly.[3][8]
Siemens will deliver 12 automated 3-carInspiro HC trains to run on the line.[35][36] Additional features of the new rolling stock were announced in January 2025.[37][38]
