Northwest Sydney
Construction and Commissioning
Transport for NSW

Sydney Metro Northwest is stage 1 of the development of Sydney Metro, Australia’s largest current transport project. 

This scheme comprised:

  • establishment of Australia’s first metropolitan railway using state of the art driverless train technology
  • track length spanning 28km of underground tunnel, 4km of viaduct and 4km of at grade track
  • 8 new stations and augmentation of 5 existing stations along with a rail maintenance facility
  • augmentation and integration of the existing Epping to Chatswood Line

Project details

UGL’s package of works included:

  • Systems JV (MTR/UGL) – Design and Build, Test and Commission of $1.3B package of works. This package includes the delivery of the trains, CBTC, controls and communications, low voltage power distribution and tunnel mechanical and electrical systems.
  • Radio Communications subcontract to SJV – a D&C contract valued at approximately $70 million to provide wireless communication systems including radio rebroadcast and mobile phone rebroadcast.
  • 20% shareholding in Metro Trains Sydney (MTS), the O&M contractor for the line.

Following completion of the design & construct contract in 2019, the railway is being operated and maintained for an initial concession period of 15 years by Metro Trains Sydney (MTS), a joint venture of UGL, MTR and John Holland. MTS is a wholly owned subsidiary of Metro Trains Australia (MTA).

The Sydney Metro Northwest project is Australia’s first driverless metro-style rail line and the introduction of this new technology requires innovation, such as:

  • The client’s reference design envisaged eight-car EMU sets as is the normal practice in Sydney. NRT’s successful tender offered six-car sets for initial service, expandable to eight cars in the future when passenger loads justify the increase. This results in savings in energy, capital and O&M costs while maintaining the level of customer service.
  • Working closely with Australia’s rail safety regulator to establish the safety case for Australia’s first driverless passenger railway.
  • Incorporating a large solar array on maintenance building rooftops at the depot with information systems to inform the public about the quantities of locally-generated solar energy on a daily basis.
  • The adoption of a cast-in sleeper system, which is new to Australia and will optimise both performance outcomes and capital cost.
  • Australia’s first fully automated passenger railway
  • NRT and TfNSW received the 2014 Government Partnership Excellence Award
  • Achieved an Infrastructure Sustainability Council of Australia (ISCA) rating of ‘Excellent’
  • Projects Grand Prix, 2015 Partnerships Awards
  • Best Transit Project, 2015 Partnerships Awards
