About

Public Transport Authority awarded a contract to DT Infrastructure Pty Ltd for the design and construction upgrade of the Sutherland St substation, replacing a single 15 MVA transformer (TF13) with two 25 MVA transformers and increasing power supply capacity on Western Power's 132kV transmission network.

The upgrade supported EMU operations and the PTA's rail network expansion by providing the increased capacity and resilience required for the Morley–Ellenbrook Line operating strategy to deliver 15 trains per hour through-running on inner-core lines (notably Midland and Fremantle) effective after December 2024.

The works aligned with PTA key result areas by addressing system reliability, availability, on-time running and customer demand and were specified in PTA230079 (Book 4) Scope of Works & Technical Criteria.
