Formerly known as Sydney Metro Greater West, the Western Sydney Airport Line will see a new metro rail line run from St Marys on the existing T1 heavy rail line to the Western Sydney Aerotropolis near Bringelly, via Western Sydney Airport (WSA).
The Station Boxes and Tunnelling (SBT) Works for Sydney Metro – Western Sydney Airport project will involve the construction of two sections of twin tunnels between St Marys and Orchard Hills stations, and between the Western Sydney Airport Terminal and Aerotropolis stations. The tunnels would have a total combined length of approximately 10 kilometres, and include associated portal dive structures.
The line alignment includes stations to be located at:
- St Marys
- Orchard Hills
- Airport Business Park
- Airport Terminal, and
- Western Sydney Aerotropolis.
The SBT Works will include station box excavations with temporary ground support at St Marys, Orchard Hills, Western Sydney Airport Terminal, Western Sydney Aerotropolis and potentially two intermediate service facilities, one in each of the tunnel sections.
