What are we doing at Wolli Creek and on the T8 Airport Line?

Upgrading the power supply will support the introduction of the new fleet of trains operating along the T8 Airport Line. It will also future-proof the connection to the Sydney Trains network, allowing more trains and services to be available to customers.

Upgrades to the power supply are along the T8 Airport Line tunnel from Central to Wolli Creek Junction.

The canopy on platforms 3 and 4 at Wolli Creek Station is also being extended to increase weather protection and encourage customers to use the full length of the platform, reducing crowding at busy times.

Wolli Creek substation upgrades

The scope of works for the Wolli Creek substation upgrades includes:

  • construction of a new substation at Wolli Creek Junction
  • decommissioning the Undercliffe Substation and Wolli Creek Sectioning Hut
  • upgrading an access way to the new substation and truck turning bay at the northern end of Lusty Street.

During December and January, the project team will carry out the following work inside the rail corridor:

  • vegetation clearing
  • piling, excavation and backfill
  • service utility installation.

T8 Line infrastructure upgrades

The scope of works for the T8 Line infrastructure upgrades include:

  • installation and modification of new power supply cables throughout the T8 Line Airport tunnel from the Chalmers Street substation through to Green Square, Mascot and Wolli Creek stations.
  • installation of a new power supply cable between Chalmers Street Substation and the Rail Operations Centre at Green Square
  • 6km of upgraded overhead wiring in T8 Line Airport tunnel
  • signalling system upgrades in T8 Line Airport tunnel.

Wolli Creek canopy extension

The scope of works for the Wolli Creek extension includes:

  • extending the canopy to cover almost the entire length of Platform 3 and 4
  • additional CCTV and lighting for improved safety and security
  • more customer seating along the platform
  • additional digital information boards and passenger announcement system to keep customers informed about departing train services in real time.

The canopy extension has received planning approval and construction is due to commence in December 2020.

Construction works

The construction work contract has been awarded and construction will start in late 2020. We will advise the community prior to the commencement of this construction.

Every effort will be made to minimise any construction impacts on the local community and we will continue to keep the community informed about upcoming activities through regular updates.
