Mortdale Maintenance Centre Upgrade

Transport for NSW acknowledges the Biddegal/Bidjigal/Bedegal people of the Eora Nation as the traditional custodians of the land known as Georges River and pay our respect to Elders past and present.

What are we doing at Mortdale Maintenance Centre?

We are upgrading the Mortdale Maintenance Centre as part of the More Trains, More Services program. The program is simplifying and modernising the rail network. It is creating high capacity, turn up and go services for many customers. It means customers can expect more frequent train services, less wait times and less crowding on a simpler and more reliable network.

This upgrade means we can use the Mortdale Maintenance Centre for Tangara fleet maintenance. Maintaining the Tangara fleet near where it operates will reduce dead running time and contribute to better services.

Project Scope

  • construction of a new bogie exchange system which will enable train wheels to be automatically removed from carriages and transported for maintenance
  • extending the driveway entrance and building a new driveway exit on the western side of the centre for improved safety during centre deliveries
  • installing a new electrical substation to support an increased electrical capacity
  • upgrading the sheds for more efficient maintenance work
  • completing civil work, e.g. track modifications, drainage upgrades, new retaining walls, electrical works and lighting.

Project Status

We completed construction of the bogie exchange system in March 2023.

Remaining work will be undertaken to complete an access road upgrade off Oatley Avenue, east of the maintenance centre.

Keeping up to date

We are committed to integrating sustainable practices into our projects and reducing environmental impacts.

Soon, we will no longer be distributing hard copy notifications to residents on this project unless requested.

Instead, we will be providing construction updates by email.

If you would like to be emailed project updates please contact us on 1800 684 490 or email projects@transport.nsw.gov.au

If our work is anticipated to directly impact your property and we do not have your contact details, we will distribute a paper notification to your address to ensure you are aware of upcoming activities.
