Trains Facility expansion

The Sydney CBD is Australia’s most significant economic and employment hub, generating $96 billion of gross domestic product per year, and is home to major tourist, entertainment and cultural destinations. A new metro station in the CBD would take pressure off the existing city stations and a new mass transit option to Parramatta, and the growing employment centres along the corridor linking the two major centres.

About the expansion work

Planning approval was provided in January 2014 for the SMTF to be built in stages. The first stage was completed in May 2019 to align with the opening of Sydney Metro Northwest, providing capacity for 22 metro trains.

The second stage of work will involve expanding the facility to accommodate an additional 37 metro trains, to meet the operational and maintenance requirements of Sydney Metro City & Southwest.

Main site features

Expansion activities on the site will include:

  • Installing new rail tracks, rail systems, lifting beams and access platforms
  • Building and fitting out maintenance sheds, building new access roads
  • Expanding the existing maintenance building, fitting out sheds and rooms
  • Installing overhead wiring and a new gantry crane
  • Modifying some existing roads.


The location of the Sydney CBD Station will be determined following further investigations and community and stakeholder engagement.
