    Guildford Substation

    We’re building a new electrical substation at Military Road near Guildford Station. The new substation will supply additional power for trains on the Main Southern Line.

      Ingleburn Substation

      We’re building a new electrical substation south-west of Ingleburn Station. The new substation will supply additional power for trains on the Main Southern Line.

        Minto Substation

        We’re building a new electrical substation near Minto Station. The new substation will supply additional power to trains on the Main Southern Line.

          Overhead wiring and feeder upgrade work

          We’re upgrading overhead wires and electrical feeders across the network to meet expected power requirements for Sydney’s future rail network and new fleet of air conditioned trains.

          Overhead wires and electrical feeders provide 1500 Volt DC power from electrical substations to our train network.

          Strathfield to Hornsby Signal Power Supply Upgrade

          We’re upgrading the network that supplies power for the rail and signalling systems between Strathfield and Hornsby electrical substations. The project includes upgrading the existing 2kV distribution network to a more powerful 11kV network and upgrading the 33kV overhead wire network.
