Railways in Melbourne
In February 2015, the State Government established the Melbourne Metro Rail Authority to oversee planning for new twin 9-kilometre rail tunnels through the central city between South Kensington station and South Yarra. The new Metro Tunnel will have five new underground stations and connect the Pakenham and Cranbourne lines with the Sunbury line, creating a new route through the CBD as an alternative to the City Loop. New underground stations will be created at Arden, Parkville, Domain and two new CBD stations, State Library and Town Hall. Enabling works were underway by 2016 and major construction work on the tunnel and stations began in 2017.The project has an estimated cost of $11 billion and is scheduled to be complete by 2025.
Vienna Pre-metro
This tunnel was opened in January 1969 an has a length of 3.4 kilometers. As part of the construction work a historic church, the "Florianikirche", has been demolished. It was planned to convert this pre-metro to a full metro line U5 from "Gumpendorfer Strasse" to St. Marx, but has never been seriously pursued. In 2016, the U5 is constructed in a different part of Vienna.
