Sydney Metro Western Sydney Airport - Station Boxes and Tunnelling Works
Project at a glance
Senior Consultant | Sydney and Sydney Surrounds
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,
Sydney Metro - Western Sydney Airport is broken into the following packages:
Enabling works - site investigation, demolition works, utility relocations, utility supplies to sites, transport network adjustments, rail corridor works etc.

John Holland, CPB Contractors (CPB) and Ghella joint venture (JCG JV) has been awarded the Eastern Tunnelling contract to deliver 3.5 kilometres of metro rail tunnels between The Bays and Hunter Street in the Sydney CBD.
This is the third and final major tunnelling package awarded on this project, and is the last piece in the tunnelling puzzle to build the 24-kilometre metro rail tunnels from Westmead to the Sydney CBD.
Sydney Metro is Australia's biggest public transport project. In 2024, Sydney will have 31 metro railway stations and a 66km standalone metro railway system, revolutionising the way Australia's biggest city travels. By the end of the decade, the network will be expanded to include 46 stations and more than 113 kms of world-class metro for Sydney.
Metro means a new generation of world-class fast, safe and reliable trains easily connecting customers to where they want to go. Customers don’t need timetables – they just turn up and go.
