Metro Tunnel Project - Rail Infrastructure Alliance

The Rail Infrastructure Alliance, a consortium consisting of John Holland, CPB Contractors and AECOM, along with project owner Rail Projects Victoria (RPV) and rail franchisee Metro Trains Melbourne (MTM), is delivering integral works on Melbourne’s rail network that will support day one operations of the Metro Tunnel, Victoria’s biggest ever transport project.
The $1b package includes cut and cover and tunnelling works at the eastern and western tunnel entrances at South Yarra and Kensington to connect the new rail tunnel to the existing network, along with additional selected platform upgrades, tunnel, track and signalling works along the Sunbury line and in Melbourne’s south-east. The Metro Tunnel Project will untangle the City Loop by taking three of Melbourne’s busiest train lines through a new tunnel under the city. It will create a new end-to-end train line, with twin nine-kilometre tunnels and five new underground stations.
