AusNet Services and Metro Trains Melbourne submitted a proposal for an improved electricity supply for Melbourne’s rail network, connected directly to the transmission network. The direct connection points will supply a new dedicated 22 kilovolt alternating current ring main along the entire metropolitan rail network with dual feeds to direct current rail traction substations on the metropolitan rail corridor.   

The proposal will provide a more efficient and reliable power supply to meet the requirements of the existing rail network and support future growth and improve the passenger journey experience. The proposal has unique characteristics.   

The Government has approved progression to Stage Three.
