The Sydney Metro City & Southwest project will connect the Southwest of Sydney to the CBD and North West, and increase total rail network capacity by 60% and deliver 31% more train services upon completion. 


Sydney Metro City & Southwest is a new 30km metro line extending metro rail from the end of Sydney Metro Northwest at Chatswood under Sydney Harbour, through to new CBD stations and Southwest to Bankstown. The line is due to open in 2024 with the capacity to run a metro train every two minutes each way through the centre of Sydney.

Delivery and Design Engineering 

SYSTRA Bamser’s specialist delivery and design engineers assisted with: 

  • Strategic value engineering support to mined tunnels for Martin Place, Victoria Cross and Pitt Street underground stations. 
  • Design and construction of Victoria Cross underground station. 
  • Utility diversions and supply and connection of critical power to various tunnelling sites. 
  • Coordinating the complicated under harbour geotechnical investigation using a “dynamic positioning vessel”. 
  • Leading the Martin Place site set-up from the concept design through to coordination of temporary works and into the start of construction. 
  • Programming and sequencing cavern and adit permanent lining works. 
  • Providing advice on tunnel fit-out and construction staging support. 

Independent Certification Services 

In a consortium with AECOM, SYSTRA ANZ is responsible for the independent certification of three Brownfield Packages, covering the requalification then modernisation of lines and existing infrastructures to accommodate the new automated metro, scheduled for commissioning by 2024. 


Sydney Metro City & Southwest will reduce traffic and bus congestion, improve train crowding and crowding at key stations including Central, Town Hall, Wynyard, and North Sydney, reduce travel times to key employment and education precincts, and improve transport resilience on the lower north shore and CBD. 


Sydney Metro is Australia’s biggest public transport project. By 2030, Sydney will have a network of four metro lines, 46 stations and 113km of new metro rail connecting Sydney’s northwest, west, southwest and greater west to fast, reliable turn-up-and-go services with fully accessible stations. The project will revitalise community spaces and enhance Sydney’s liveability and culture, providing better access to employment, health, and education centres as well as major sporting and entertainment precincts.
