The Oslo Metro (Norwegian: Oslo T-bane or Oslo Tunnelbane or simply T-banen) is the rapid transit system of Oslo, Norway, operated by Sporveien T-banen on contract from the transit authority Ruter. The network consists of six lines that all run through the city centre, with a total length of 85 kilometres (53 mi), serving 100 stations of which 16 are underground or indoors. In addition to serving 14 out of the 15 boroughs of Oslo (all except St. Hanshaugen), two lines run to Bærum. In 2014, the system had an annual ridership of 88 million.
The first rapid transit line, the Holmenkoll Line, opened in 1898, with the branch Røa Line opening in 1912. It became the first Nordic underground railway in 1928 when the underground line to Nationaltheatret was opened. The Sognsvann Line opened in 1934 and the Kolsås Line in 1942. The opening of the upgraded T-bane system on the east side of town occurred in 1966, after the conversion of the 1957 Østensjø Line, followed by the new Lambertseter Line, the Grorud Line and the Furuset Line; in 1993 trains ran under the city between the two networks in the Common Tunnel, followed by the 2006 opening of the Ring Line. All the trains are operated with MX3000 stock. These replaced the older T1000 stock between 2006 and 2010.
Oslo (English pronunciation: /ˈɒzloʊ/, OZ-loh,Norwegian pronunciation: [ˈuʂˈlu] ( listen) or, rarer [ˈusˈlu] or [ˈuʂlu]) is the capital and the most populous city in Norway.
Oslo constitutes both a county and a municipality. Founded in the year 1040, and established as a "kaupstad" or trading place in 1048 by King Harald III, the city was elevated to a bishopric in 1070 and a capital under Haakon V around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 and with Sweden from 1814 to 1905 reduced its influence. After being destroyed by a fire in 1624, the city was moved closer to Akershus Fortress during the reign of King Christian IV and renamed Christiania in his honour. It was established as a municipality (formannskapsdistrikt) on 1 January 1838. Following a spelling reform, it was known as Kristiania from 1877 to 1925, at which time its original Norwegian name was restored.
Oslo is the economic and governmental centre of Norway. The city is also a hub of Norwegian trade, banking, industry and shipping. It is an important centre for maritime industries and maritime trade in Europe. The city is home to many companies within the maritime sector, some of which are among the world's largest shipping companies, shipbrokers and maritime insurance brokers. Oslo is a pilot city of the Council of Europe and the European Commission intercultural cities programme.
Oslo Central Station (Norwegian: Oslo sentralstasjon, abbreviated Oslo S) is the main railway station in Oslo, and the largest railway station within the entire Norwegian railway system. It is the terminus of Drammen Line, Gardermoen Line, Gjøvik Line, Hoved Line and Østfold Line. It serves express, regional and local rail services by four companies. The railway station is owned and operated by Norwegian National Rail Administration and was opened in 1980.
Oslo Central was built on the site of the older Oslo East Station (Oslo Østbanestasjon, Oslo Ø), the combining of the former east and west stations being made possible by the opening of the Oslo Tunnel. Oslo Central has nineteen tracks, thirteen of which have connections through the Oslo Tunnel. The station has two buildings, the original Oslo East building and the newer main building for Oslo Central. Each building houses a large shopping centre. The square in front of the station is called Jernbanetorget.
