Sydney Metro - Western Sydney Airport Line (formerly Sydney Metro Greater West or North South Rail Link) is a proposed infrastructure project that would link the Western Sydney Airport and Aerotropolis to the rail network. It will operate as part of Sydney Metro, and likely utilise similar rollingstock.

The line is expected to open along with the Western Sydney Airport in 2026. It has currently been confirmed to run between St Marys station and Western Sydney Aerotropolis.

Description and History
Sydney Metro Greater West is part of the "Western Sydney City Deal", an agreement between the state, federal and local governments signed in March 2018. The deal would see joint funding and coordination of various projects in the area including, but not limited to, the North-South rail link.

A scoping study was held between Nov 2015 and March 2018 to determine the "long-term need, timing, and service options for passenger rail to service both Western Sydney and its airport." The report found a need for a "North-South" and "East-West" connection to the airport in order to "address congestion" and "growing demand for services" over the next 40 years. This North-South connection would stretch from Schofields to Macarthur, with interchanges at St Marys and the Aerotropolis.

The project was renamed the Western Sydney Airport Line in June 2020. More information was released at the same time, showing that construction on the line will start in late 2020. More stations and an approximate alignment were confirmed. St Marys to Orchard Hills and the area around the airport will be underground, with the rest of the stations at ground level or on viaducts.

It is also stated in another scoping study released in June 2020 that the project will safeguard: A train stabling facility will be built for the line. It is proposed that this will be between the Warragamba pipeline and the M4 Western Motorway.
 * an extension north to Schofields or Tallawong (to connect with heavy rail services on the Richmond branch and the Metro North West Line)
 * an extension south to Macarthur (to connect with heavy rail services on the Main Southern line)
 * a future rapid bus network
 * the proposed East-West Link
 * the proposed extension of the South West Rail Link

Plans are also underway to extend the line to Macarthur, with new Metro stations at Oran Park and Narellan, and new underground Metro platforms at Macarthur. A second connection from the airport to Leppington is also likely in the future.
