Wollongong to Coniston Infrastructure Upgrade

Transport for NSW acknowledges the Dhawawal people as the Traditional Custodians of the lands on which we work and pay respects to Elders past and present. We recognise & celebrate the diversity of Aboriginal peoples and their ongoing cultures & connections to the lands and waters of NSW.

The NSW Government is upgrading rail infrastructure between Wollongong to Coniston as part of the More Trains, More Services program.

This program will simplify and modernise the rail network creating high capacity, turn up and go services for many customers. It means customers can expect more frequent train services, with less wait times, less crowding on a simpler and more reliable network.

Key Benefits

Electrical upgrades are required to improve train movements along the network between Wollongong and Coniston. We will be working within and adjacent to the rail corridor to:

  • replace electrical cables and overhead wiring infrastructure at Coniston substation
  • install new infrastructure in the rail corridor to support service enhancements
  • modify electrical assets and combined service routes including installation of new electrical cabling
  • modify overhead wiring and structures
  • complete civil and structural activities to support corridor upgrades.

Project Status

A contract has been awarded to Transport for Tomorrow, an alliance between Transport for NSW, Laing O’Rourke and KBR, to start early work for the Wollongong to Coniston Infrastructure Upgrade project.

Over the coming months, we will be completing:

  • site walks for the design, construction, environment and safety teams to allow for future planning
  • 3D scanning and non-destructive digging to identify underground services
  • identification of existing service and signalling routes
  • adjustment and installation of combined service routes
  • Coniston substation and overhead wiring structure design investigation and adjustment
  • installation of eight solar lights inside the rail corridor at North Wollongong
  • installing underground cable routes
  • installing new cables and equipment in the substation.

Transport for Tomorrow have already delivered platform extensions and stabling yard upgrades at Wollongong Station, as well as signalling and safety upgrades at Coniston Station as part of an earlier package of work.


Keeping you up to date

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

After May 2023, 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.
