Victoria’s Big Build

Sunbury Line Substations Package - Tottenham Substation Extension

Multiworks is partnering with Metro Trains Melbourne (MTM) to deliver major upgrade works at the Tottenham Substation as part of the Sunbury Line Upgrade and Metro Tunnel Projects.

The Tottenham Substation Extension will support the introduction of MTM’s new High Capacity Metro Trains, requiring traction power upgrades along the Sunbury to Dandenong corridor.

The new trains are a vital component to the expansion of Melbourne’s metropolitan rail network, and will greatly improve the capacity, reliability and frequency of Sunbury Line train services.

Multiworks will deliver civil, structural and building works at the existing substation to accommodate the additional 3MW traction power transformer, rectifier and associated switchgear.

We are proud to support MTM in expanding its train network capacity. Once completed the network will accommodate more than a half a million additional passengers per week during Melbourne’s peak periods.
