Mascot Power Supply Project

What are we doing at Mascot?

Transport for NSW is upgrading the power supply to support an increase to the number of services operating through the T8 Airport Line tunnel, and support the introduction of the new fleet of trains operating along the T8 Airport Rail Line.

Upgrades include:

  • construction of a new substation at 166 O’Riordan Street, Mascot
  • cabling route from the new substation to Mascot Station, which will be created using an underground tunnel boring machine
  • new lighting and CCTV and security fencing around the substation and the mobile antenna located behind the new substation.

Project update

During November, we continued with geotechnical, utility and survey investigations in the area to help inform the detailed design for the project. The project team began site establishment at 166 and 200 O’Riordan Street, Mascot ahead of starting work on site.

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

  • delivery of site sheds to 166 and 200 O’Riordan Street
  • excavation and piling at 166 O’Riordan Street
  • installation of survey markers on O’Riordan Street, Bourke Road and Bourke Street.

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.
