The Oslo Metro (Oslo T-bane) is the rapid transit system of Oslo, Norway. The network consists of six lines that all run through the city center, with a total length of 84.2 kilometres (52.3 mi). It has a daily ridership of 268,000 (2009) with 105 stations of which 16 are underground or indoors.
Shown here is a fairly recent (2006) redesign of the Oslo Metro map, by Truls Lange, revealing a fresh execution. You can see the previous version of the map, or take a better look (pdf) at the new one.
