The '''Oslo Metro''' ({{langx|no|Oslo T-bane}} or {{lang|no|Oslo Tunnelbane}} or simply {{lang|no|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 five lines that all run through the city centre, with a total length of {{convert|85|km|mi}},<ref name="stats">{{cite web |url=https://ruter.no/globalassets/dokumenter/aarsrapporter/ruter-arsrapport-2014.pdf |title=Årsrapport 2014 |publisher=Ruter |language=no |trans-title=Annual Report 2014 |page=21 |year=2014 |access-date=2015-06-05 |url-status=live |archive-url=https://web.archive.org/web/20160110065202/https://ruter.no/globalassets/dokumenter/aarsrapporter/ruter-arsrapport-2014.pdf |archive-date=2016-01-10 }}</ref> serving 101 stations of which 17 are underground or indoors. In addition to serving 14 out of the 15 [[List of boroughs of Oslo|boroughs of Oslo]], two lines run to [[Kolsås]] and [[Østerås]], in the neighbouring municipality of [[Bærum]]. In 2016, the system had an annual ridership of 118 million.<ref name=ridership>{{cite web |url=https://ruter.no/globalassets/dokumenter/aarsrapporter/ruter-arsrapport-20161.pdf |title=Ruter Årsrapport 2016 |publisher=Ruter |language=no |trans-title=Ruter Årsrapport 2016 |date=2017 |access-date=2017-07-24 |url-status=live |archive-url=https://web.archive.org/web/20171214124757/https://ruter.no/globalassets/dokumenter/aarsrapporter/ruter-arsrapport-20161.pdf |archive-date=2017-12-14 }}</ref>

The first rapid transit line, the [[Holmenkollen Line]], opened in 1898, with the branch [[Røa Line]] opening in 1912. It became the first Nordic underground rapid transit system in 1928, when the underground line to [[Nationaltheatret (station)|Nationaltheatret]] was opened. After 1993 trains ran under the city between the eastern and western networks in the [[Common Tunnel]], followed by the 2006 opening of the [[Ring Line (Oslo)|Ring Line]]. All the trains are operated with [[OS MX3000|MX3000]] stock. These replaced the older [[OS T1000|T1000]] stock between 2006 and 2010.

===Suburban lines in the west===
Rail transport in Oslo started in 1854, with the opening of [[Hoved Line]] to Eidsvoll, through [[Grorud Valley|Groruddalen]]. In 1872, [[Drammen Line]], going through Oslo West, and in 1879, [[Østfold Line]] going through [[Nordstrand, Norway|Nordstrand]] opened, offering a limited rail service to those parts of the city.<ref>Bjerke and Holom, 2004: 9</ref> By 1875, [[Kristiania Sporveisselskab]] (KSS) opened the first horsecar trams.<ref>Aspenberg, 1994: 6</ref> In 1894 electric trams were in service by [[Kristiania Elektriske Sporvei]] (KES).<ref name=trikk7>Aspenberg, 1994: 7</ref>

The first suburban tram line was the [[Holmenkollen Line]] that was opened by [[Holmenkolbanen]] in 1898; like all the later suburban tram line these were electric trams with a grade-separated right-of-way and proper stations instead of tram stops, making it the first rapid transit in Oslo. Unlike the other suburban tram lines that were built later, the Holmenkollen Line was not extended into the city as a streetcar—instead passengers had to change at [[Majorstuen (station)|Majorstuen]] to the streetcars, though the system did not take into use wider suburban stock ({{convert|3.1|m|ftin}}) until 1909.<ref>Aspenberg, 1994: 8</ref> A branch line was opened in 1912, to [[Smestad (station)|Smestad]],<ref>Aspenberg, 1994: 12</ref> and in 1916 the Holmenkollen Line was extended to Tryvann, with the last part from [[Frognerseteren (station)|Frognerseteren]] single track and used for freight,<ref>Aspenberg, 1994: 14</ref> and removed in 1939.<ref name=bh347>Bjerke and Holom, 2004: 347</ref>

In 1912, the construction of the first underground railway in the Nordic Countries started, when ''A/S Holmenkolbanen'' started construction of an extension of their line from Majorstuen to [[Nationaltheatret (station)|Nationaltheatret]]. The {{convert|2.0|km|mi}} line was opened in 1928, with one intermediate station at [[Valkyrie plass (station)|Valkyrie Plass]], giving the two suburban lines access to the central business district of Oslo.<ref name=trikk17>Aspenberg, 1994: 17</ref> In retrospect, it is seen as an early [[premetro]] example.<ref name="TECWP">{{cite book |last1=Burtenshaw |first1=D. |last2=Bateman |first2=M. |last3=Ashworth |first3=G.

The success of the suburban lines tempted KES to extend their streetcar service west from [[Skøyen Station|Skøyen]] as a suburban line; the [[Lilleaker Line]] opened to [[Lilleaker (station)|Lilleaker]] in 1919, to [[Avløs (station)|Avløs]] in 1924 and to [[Kolsås (station)|Kolsås]] in 1930. A new section from [[Jar (station)|Jar]] to [[Sørbyhaugen (station)|Sørbyhaugen]] opened in 1942, connecting the line from Jar to Kolsås to Nationaltheatret, and making it a rapid transit and the replacement of stock with wide suburban standard.<ref name=bh346>Bjerke and Holom, 2004: 346</ref><ref name=historikk /> This service remained part of the municipal [[Oslo Sporveier]], that had bought all the streetcar companies in 1924.<ref>Aspenberg, 1994: 19</ref>

Compensation for large amounts of damage to houses along the route during construction, along with higher construction costs than calculated was a heavy burden on the company, and in 1934, the municipality of [[Aker, Norway|Aker]] took over the common stock, though the preferred stock remained listed on the [[Oslo Stock Exchange]] until 1975, as Oslo Sporveier gradually took over the operation of the western suburban lines. [[Akersbanerne]] opened the connecting [[Sognsvann Line]] in 1934.<ref name=trikk17 />

===Metro===
[[File:Forskningsparken tbane.jpg|thumb|[[OS T1000|T1000]] stock at [[Forskningsparken (station)|Forskningsparken]] on the Sognsvann Line]]
The first idea to launch a citywide rapid transit was launched in 1912 with the construction of the [[Ekeberg Line]]; constructed with the same width profile as the Holmenkollen Line, the plan was to build a tunnel under the city center and run through trains, but large cost expenditures on the first section of the [[Common Tunnel]] ceased the plans. As part of the rebuilding after [[World War II]] a planning office for a T-bane was established in 1949, with the first plans launched in 1951; in 1954, the city council decided to build the T-bane network in Eastern Oslo with four branches. The system would feature improvements over the suburban lines in having a [[third rail]] power supply, [[cab signalling|cab signaling]] with [[Automatic Train Protection]], stations long enough for six-car trains and [[level crossing]]s replaced by bridges and underpasses—specifications christened metro standard.<ref name=trikk29>Aspenberg, 1994: 29</ref>

At the time there were two suburban tramways on the east side, the Ekeberg Line (opened in 1919)<ref name=trikk7 /> and the [[Østensjø Line]] (1923).<ref>Aspenberg, 1994: 16</ref> Only the latter would be connected to the T-bane; the Ekeberg Line would remain a tramway, but three new lines were to be built—the [[Grorud Line]] on the north side and the [[Furuset Line]] on the south side of [[Grorud Valley|Groruddalen]] and the [[Lambertseter Line]] on the east of [[Nordstrand, Norway|Nordstrand]]. These areas were all chosen as new [[suburb]]s for Oslo, and would quickly need a good public transport system; suburban lines would first be built out extending from the existing tramway, and later a final section with tunnel to the central station would be built. The Lambertseter Line was opened in 1957, from [[Brynseng (station)|Brynseng]] to [[Bergkrystallen (station)|Bergkrystallen]] while the Østensjø Line was extended to [[Bøler (station)|Bøler]] in 1958.<ref name=trikk29 />

The metro opened on 22 May 1966, when the Common Tunnel opened from Brynseng to the new downtown station of [[Jernbanetorget (station)|Jernbanetorget]], located beside the [[Oslo Central Station|Oslo East Railway Station]]. In October the Grorud Line opened to [[Grorud (station)|Grorud]] while the Østensjø Line was connected to the system in 1967 when the line also was extended to [[Skullerud (station)|Skullerud]]. In 1970, the Furuset Line opened to [[Haugerud (station)|Haugerud]] and extended to [[Trosterud (station)|Trosterud]] in 1974, at the same time as the Grorud Line was extended to [[Vestli (station)|Vestli]]. By 1981, the Furuset Line had reached [[Ellingsrudåsen (station)|Ellingsrudåsen]].<ref>Aspenberg, 1994: 29–30</ref> The metro took delivery of [[OS T1000|T1000]] rolling stock from [[Strømmens Værksted]]; from 1964 to 1978, 162 cars in three-car configurations were delivered for the eastern network.

===One tunnel===

The eastern network was extended from Jernbanetorget to [[Stortinget (station)|Sentrum]] in 1977. This station was forced to close in 1983, due to water leakage, and when it opened again in 1987, renamed Stortinget, the west network tunnel had also been extended there. Through services were not possible at the time because of incompatibility of signaling and power equipment. Not until 1993 did the first trains run through the station, after the Sognsvann Line had been rebuilt to "metro standard"; the Røa Line followed in 1995.<ref name=trikken30>Aspenberg, 1994: 30</ref> The Holmenkollen and Kolsås Lines remained non-metro, using dual mode trains that switch to [[overhead lines]] at [[Frøen (station)|Frøen]] and [[Montebello (station)|Montebello]].<ref name=milepaler>{{cite web |url=http://www.sporveien.no/Kultur-og-historie-/153/ |title=Milepæler 1875–2005 |author=Oslo Sporveier |access-date=2008-06-09 |archive-url = https://web.archive.org/web/20080429042349/http://www.sporveien.no/Kultur-og-historie-/153/ <!-- Bot retrieved archive --> |archive-date = 2008-04-29|author-link=Oslo Sporveier }}</ref> The western network took delivery of 33 [[OS T1000|T1300]] cars in 1978–81, with an additional 16 converted from T1000. In 1994 twelve [[OS T2000|T2000]] cars were delivered for the Holmenkollen Line.<ref name=trikk62>Aspenberg, 1994: 62</ref>

In 2003 the [[Ring Line (Oslo)|Ring Line]] opened, connecting [[Ullevål stadion (station)|Ullevål stadion]] to [[Storo (station)|Storo]].<ref name=historikk /> The following year, construction work caused a tunnel to collapse on the Grorud Line—the system's busiest—forcing a shutdown of the line until December, and creating a havoc of overcrowded replacement buses.<ref>{{cite web |url=http://www.groruddalen.no/full-stopp-for-grorudbanen.174300-77747.html |title=Full stopp for Grorudbanen |author=Akers Avis Groruddalen |date=2004-07-28 |url-status=live |archive-url=https://web.archive.org/web/20120513174836/http://www.groruddalen.no/full-stopp-for-grorudbanen.174300-77747.html |archive-date=2012-05-13 |author-link=Akers Avis Groruddalen }}</ref> In 2006 the ring was completed, to [[Carl Berners plass (station)|Carl Berners plass]].<ref name=historikk /> At the same time the Kolsås Line was closed for upgrade to metro standard.<ref name=historikk /> In 2003 the section of the Kolsås Line in Bærum closed due to budget disagreements between the two counties; after a year of unpopular replacement [[bus]]es, the line was reopened, only to close again in 2006 for upgrade to metro standard.

The Oslo Metro operates in all fifteen boroughs of Oslo, as well as reaching a bit inside the neighbouring municipality of [[Bærum]]. There are five lines, numbered 1 to 5, each colour-coded. They all pass through the Common Tunnel, serving eight branch lines. In addition two lines operate to the Ring Line. Two branches are served by two lines each: the Grorud branch is served by both lines 4 and 5, while the Lambertseter branch has full-time service by line 4 and limited service by line 1.<ref name=rutetider>{{cite web|url=https://ruter.no/globalassets/rutetabeller/oslo/t-bane-rutetabell-03042016.pdf |title=Rutetabell for T-banen |author=Ruter |year=2016 |access-date=2016-04-03 |language=no |url-status=dead |archive-url=https://web.archive.org/web/20160416042805/https://ruter.no/globalassets/rutetabeller/oslo/t-bane-rutetabell-03042016.pdf |archive-date=2016-04-16 |author-link=Ruter }}</ref>

The Grorud and Furuset Line head northeast into Groruddalen, while the other two eastern branches head south into Nordstrand. On the west side, the Holmenkoll and Sognsvann Line cover the northern boroughs of Oslo, along with the Ring Line that connects the northeastern and northwestern parts of town. The Kolsås and Røa Line reach deep into the neighbouring municipality of Bærum.<ref name=historikk>{{cite web |url=http://www.tbane.no/index.aspx?cat=615223&id=745387&mid=745387 |archive-url=https://web.archive.org/web/20110526090844/http://www.tbane.no/index.aspx?cat=615223&id=745387&mid=745387 |url-status=dead |archive-date=2011-05-26 |title=Kort historikk |author=Oslo T-banedrift |access-date=2008-06-09 |language=no|author-link = Oslo T-banedrift}}</ref> All the lines run through the Common Tunnel before reaching out to different lines, or into the Ring. All lines have a base service of four trains per hour while line 2 and the eastern section of line 3 have eight trains per hour weekdays 07:00–19:00. The eastern section of line 2 also has eight trains per hour Saturdays 10:00–19:00. A reduced half-hourly service operates on all lines during early weekend mornings. Trains run from about 05:00 (06:00 at weekends) to 01:00 the next morning.<ref name=rutetider />

==Rolling stock==
[[File:I12 065 Hp Røa, ET 3198.jpg|thumb|[[OS MX3000|MX3000]] stock on the [[Ring Line (Oslo)|Ring Line]]]]
{{Main|Oslo Metro rolling stock}}
The trains on the Oslo metro are currently exclusively the [[OS MX3000|MX3000]], ordered in 2003 to replace the oldest [[OS T1000|T1000]]. Delivery started in 2006, and unlike older stock the MX3000 units are painted white instead of red. 83 three-car units were ordered in 2006;<ref name=mx3000 /> a further 32 were ordered in December 2010.<ref>{{cite web|url=http://www.railwaygazette.com/nc/news/single-view/view/oslo-orders-more-metro-cars.html|access-date=2010-12-24|title=Railway Gazette: Oslo orders more metro cars|date=2010-12-24|url-status=live|archive-url=https://web.archive.org/web/20110616014236/http://www.railwaygazette.com/nc/news/single-view/view/oslo-orders-more-metro-cars.html|archive-date=2011-06-16}}</ref>

A number of versions of the T1000 stock have previously been used on the Oslo metro. This includes 146 cars of the types T1 through T4, which have third-rail only operation, and thus did not run on the Holmenkollen and Kolsås lines. These ran usually in units of three or six (sometimes four or five) cars. Types T5 to T8, 49 in total, delivered with both third-rail and overhead wire equipment, normally ran on the Holmenkollen line (two cars) and the Kolsås line (three cars).<ref name=trikk62 />

When the Holmenkollen Line was connected to the T-bane it was still using old teak cars; to allow through services the [[OS T2000|T2000]], capable of dual-system running, was delivered in 1993. They were not particularly successful{{clarify|date=July 2025}}, and only 12 units were delivered, operating in pairs on the Holmenkollen line sometimes connecting with the Lambertseter line, and were scrapped in 2010.<ref>{{cite web|url=http://www.tbane.no/userfiles/T-2000.doc |title=T-2000 |author=Oslo T-banedrift |access-date=2008-06-09 |language=no |url-status=dead |archive-url=https://web.archive.org/web/20110526091015/http://www.tbane.no/userfiles/T-2000.doc |archive-date=May 26, 2011 }}</ref>
