Sydney Metro City & Southwest

Sydney Metro City & Southwest is a 30km rapid transit rail project in Sydney, New South Wales, Australia currently under construction. The project will form an extension of the Sydney Metro North West Line from Chatswood on the North Shore, to Bankstown in the city's south-west via the Sydney central business district. The centrepiece of the project is a new 15.5km[1] twin-tunnel rail crossing under Sydney Harbour and through the city to Sydenham. Together with planned improvements to the Main Western railway line, the project is expected to increase capacity on the Sydney rail network by up to 60%, and allow for the movement of over 100,000 extra commuters across the network every hour.[2]

The project is managed by the New South Wales Government's transport authority, Transport for NSW. Construction began in 2017 and the extension is planned to open by 2024.[3] It is estimated to cost between $10–11 billion.[4]


The line will connect Chatswood–the initial terminus of the Sydney Metro North West Line–to Sydenham. At Sydenham, the line would join the existing Bankstown railway line, which would be converted to rapid transit operation between Sydenham and Bankstown. The combined route between Chatswood and Bankstown is called Sydney Metro City & Southwest.

The following stations are proposed:[5]

The original list of stations consisted of Crows Nest, Victoria Cross, Martin Place, Pitt Street, Central, Sydenham and the stations of the Bankstown line. Potential additional stations were also proposed for the industrial area of Artarmon, Barangaroo and either the University of Sydney or Waterloo.[5][7] Barangaroo station was confirmed in June 2015 and Waterloo was confirmed in December.[6][8] The other three stations will not be included in the project.

The remaining stations served by the T3 Bankstown Line - Erskineville, St Peters and stations between Bankstown, Lidcombe and Cabramatta - will continue to be served by Sydney Trains, but more detailed plans have not been revealed.[9]


Metropolitan Rail Expansion Program

The Redfern to Chatswood Rail Link (RCRL) was a component of the now-cancelled Metropolitan Rail Expansion Programme (MREP). First announced in 2005, the line was to have started at Redfern station, travelled under the city centre, crossed under Sydney Harbour, passed through the lower North Shore and ended at the existing Chatswood railway station. It was to have provided the centre section of a planned North West-CBD-South West rail arc connecting major areas of employment with the CBD and Sydney Airport.

Alternative names for the planned route have included the "Redfern to Chatswood Harbour Rail Link", "MetroPitt" and the "CBD Rail Link". In March 2008 the State Government announced that the line would be cancelled, its role to be partly superseded by future metro rail lines.[10] In 2010 the CBD Relief Line & Western Express concept was announced. This is largely a return to the CBD Rail Link proposal, but uses a different alignment and links to different lines.

The proposal was announced on 15 June 2005 and formed part of the $8 billion Metropolitan Rail Expansion Project (MREP). The MREP consisted of the New South Wales government's $8 billion North West - CBD - South West line, including the North West Rail Link to Rouse Hill, and the South West Rail Link to Leppington in Sydney's South West. The six kilometre RCRL was slated to cost $5 billion, and was to include duplicated tracks on the North Shore railway line between St Leonards and Chatswood. It was to provide a second rail crossing of Sydney Harbour to ease congestion at Town Hall and Wynyard stations, both considerably crowded and unable to be easily expanded, and to reduce travel times between the city and the lower North Shore.

The government's previous plan of constructing an additional CBD underground line was known as MetroWest. It was to have run from Haymarket along the western edge of the city under Sussex or Kent Street and either ended at Wynyard station or continued over the harbour 'strapped' to the Sydney Harbour Bridge. This option would not have served the part of the city experiencing the fastest growth of employment, and would have necessitated the destruction of eight office buildings. A previous MetroPitt proposal, travelling further east (and under its namesake Pitt Street) and through the financial district, could also be built deeper underground, limiting the impact on existing infrastructure.

In 2006, both of these corridors were protected with planning buffers to allow the option of future construction.[11] Developers who want to excavate deeper than two metres within a 25-metre buffer zone of the corridors need to seek RailCorp's approval.[12]

In the plan the stations along the RCRL would have included:[13]

  • Redfern
  • Central
  • Pitt Street
  • Martin Place
  • Circular Quay
  • Victoria Cross
  • Crows Nest
  • St Leonards
  • Chatswood

A map[14] of the protected corridors suggested there may have been the potential for another station at Macquarie Place, between The Rocks and Castlereagh Street.

Current proposal

In 2013, a new proposal was raised to extend the North West Rail Link (subsequently known as Sydney Metro Northwest), by building a metro tunnel from just south of Chatswood station via St Leonards and North Sydney and under the Sydney Harbour towards Central and Redfern, before joining the newly converted metro lines towards Hurstville, Bankstown, Lidcombe and Liverpool.[15] This largely renews the previous proposal for the RCRL, except with metro-style trains instead. The Hurstville extension may subsequently have been dropped.

The proposal was officially announced by the NSW Government on 10 June 2014. The proposal was contingent on funding from privatising at least 49% of the state's power infrastructure, which was secured in June 2015.[16][17] Preliminary works involving drilling to depths 70m below Sydney Harbour commenced on 9 April 2015 to find the alignment for the new Sydney Metro tunnels.[2][18] Planning approval for the Chatswood to Sydenham section of the project was received in January 2017.[19]

In June 2017, a John Holland, CPB Contractors and Ghella joint venture was awarded the contract to build the twin tunnels from Chatswood to Sydenham.[20]

A contract for a major upgrade of Central station was awarded to Laing O'Rourke in March 2018. The project includes construction of two new underground platforms to serve the metro and a new underground concourse called Central Walk. The new platforms will be built beneath platforms 13-14.[21]

Tunnelling commenced in October 2018.[22]

In November 2018 a $1.376 billion contract was awarded to an unincorporated joint venture between CPB Contractors and UGL to be known as Systems Connect, which will include the laying of track from Chatswood to Sydenham as well as converting power on the Bankstown line to metro standards and also the building of further metro train facilities at Rouse Hill and Marrickville.[23]
