E-Class tram

Power Supply Upgrade Project

The Victorian Government has invested $1.3 billion for new trams and supporting infrastructure to revitalise Melbourne’s tram network.

This investment includes the purchase of 80 next-generation E-Class trams — the largest on our network — as well as upgrades to Route 96 (the first route to receive the new trams), the redevelopment of two tram depots, accessibility improvements and power supply upgrades. the roll out of E-Class trams on Route 96 also means that other larger trams currently running on this route can move to other busy routes, as part of a cascading program.

These changes across the network will significantly increase the overall energy consumption for the tram network. To continue the optimal performance of the tram network, new power substations will be required at key locations across Melbourne.

Project description

The Power Supply Upgrade Project includes:
• the construction of new substations at key locations around Melbourne;
• the upgrade of existing substations;
• installation of new overhead and underground feeder cables; and
• installation of associated power infrastructure.

Why do we need more power for the tram network?

Electrical substations around the network convert electricity supplied from utility providers to the required tram power supply. Substations then distribute this converted supply to the network’s overhead wire system. A power system study found that the increased size and more modern features of E-Class trams, including air conditioning and automated announcements, means they require more power to run properly.
