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.

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.

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 - now complete

During October 2021 we completed the work on extending the platform canopy at Wolli Creek Station which will increase weather protection and encourage customers to use the full length of the platform, reducing crowding at busy times.

This work involved:

  • 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.
