Tram substation upgrades in Australia

Melbourne’s Tram Network Substation Upgrade

Melbourne’s tram network is undergoing substation upgrades to support modern, high-capacity trams and improve network reliability.

Key aspects include:

• Technical requirements: New substations convert 6.6-22kV AC to 600V DC using transformers and rectifiers. Modern E-Class trams require 20-30% more power than older models, necessitating infrastructure upgrades
• Environmental considerations:
  • Electromagnetic field (EMF) mitigation measures
  • Native vegetation preservation protocols
  • Graffiti-resistant cladding solutions
