Metro Tunnel
The Metro Tunnel (sometimes also known as the Melbourne Metro Rail Project or the Metro Rail Capacity Project) is a metropolitan rail infrastructure project currently under construction in Melbourne, Australia. It includes the construction of twin 9-kilometre rail tunnels between South Kensington station (north west of the Melbourne City Centre) and South Yarra (in the south east) with five new underground stations. The southern portal for the tunnel is to be located to the south of South Yarra station. As a result, the tunnel will connect the Pakenham and Cranbourne lines with the Sunbury line, and allow these lines to bypass Flinders Street station and the City Loop while still stopping in the Melbourne central business district.

On the other hand, transport economist Chris Hale has argued that while the capacity increase offered by the tunnel is real and probably more significant than that offered by incremental upgrades to the existing network, the project is the product of poor planning processes in the Victorian transport bureacracy and consequently reflects a "single-issue" approach to infrastructure which is inconsistent with contemporary best practice. Hale contends that the tunnel's route, which reinforces existing transport networks and focuses on the inner city as the single connection point of all transport, exemplifies outmoded thinking and, therefore, achieves its primary aims while failing to accomplish more extensive benefits for a similar cost.
