The Sunbury Line and the Metro Tunnel When the Metro Tunnel opens in 2025 the Sunbury Line will run through new tunnels under Melbourne’s CBD, with bigger, more modern trains, next-generation signalling technology and five new stations.

The Metro Tunnel is the first step towards a metro-style rail network for Melbourne, with the turn-up-and-go rail services that are the hallmark of the world’s great cities.

It will transform Melbourne’s train network, connecting passengers to five new underground stations and slashing travel times by up to 50 minutes a day.
