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.
City Tunnel (Malmö)
The City Tunnel () is a 17-kilometre rail link in Malmö, Sweden, running between Malmö Central Station (Malmö C) and the Øresund Bridge, of which six kilometres under Malmö city centre is in tunnel, to increase capacity on the Scanian network by changing Malmö C from a terminus to a through station. It's a part of the Oresund Line to Copenhagen Central Station. The work was projected to cost 9.45 billion SEK. Under construction since March 2005, the line was inaugurated by King Carl XVI Gustaf of Sweden on December 4, 2010, and revenue service commenced on December 12, 2010. Unlike other dual track railways in Sweden, is right-side traffic used. The spot at which the two tracks shifts side, is located in Arlöv around 5 km north-east of Malmö Central Station, and isn't considered to be a part this particular railway.
