List of Sydney Trains Transmission Lines

The following is a list of transmission lines (feeders) operated by Sydney Trains that powers railway infrastructure, including electric trains, signalling and lighting. Sydney Trains operates high voltage transmission lines at 33 kV, 66 kV and 132 kV AC as well as signalling transmission lines at 2 kV and 11 kV AC. Transmission lines are usually aerial power lines, but in some cases the lower voltages (11 kV and 33 kV) are located in overground or underground metal ducts that can often be spotted alongside railway tracks or in rail corridors.

High voltage transmission lines are coordinated by Sydney Trains' Infrastructure Control Electrical (ICON) team, also known as Electrical Operating Centre (EOC) who can be contacted at (02) 9379 4911.

Transmission lines are numbered with a (typically) 3-digit code. The first digit in the code can be used to determine the transmission line voltage, or alternatively by counting the number of glass/porcelain insulators connecting the line to the pole. Feeders can be identified by yellow metal plates nailed to the power poles.

132kV Transmission Lines
There is only one 132 kV transmission line in the Sydney Trains distribution network. It is Feeder 286, which supplies Sydney Trains Heathcote Substation via the Ausgrid 132 kV transmission line to Engadine Zone Substation (Ausgrid).
