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.
Melbourne Metro 2
By 2015, with planning work for the first Metro Tunnel underway, the "Herald Sun" began referring to the second tunnel as "Metro 2", as the state government confirmed that the new Parkville station would be designed with provision for future expansion to an interchange. At the same time, the newspaper reported that the state government of premier Daniel Andrews was broadly supportive of the need for a second major rail project at the completion of the Metro Tunnel.
