Oslo Metro is therapid transit system that servesOslo andBærum in Norway. The system is municipally owned bySporveien^[1] and operated by the subsidiarySporveien T-banen, which is in contract withRuter. The metro served 85 million passengers and operated 7 million train-kilometers (4.3 train-mi) in 2013.^[2] It serves 95 stations;^[3] of which 15 are underground and 1 is built-in.^[4] In addition, 15 stations have been closed, while 4 stations on theKolsås Line remain temporarily nonoperational since 2006 while the line is being upgraded.^{[5][6][needs update]}

The most heavily trafficked station isJernbanetorget, which is adjacent toOslo Central Station, closely followed byMajorstuen, the maintransfer station between lines west of the city center and to several lines of theOslo Tramway, andNationaltheatret, which is in the heart of the city center and provides direct transfer to trains on theDrammen Line. All three stations are in theCommon Tunnel. The least-used station isLillevann, which serves the recreational area ofNordmarka.^[7] At a distance of 17.3 kilometers (10.7 mi),Kolsås is the farthest from the city center.^[8]

The system is served by eight lines that operate as branches from theCommon Tunnel—the shared section that runs 4.8 kilometers (3.0 mi) through the city center.^[8][9] TheRing Line operates in a loop north of the city center.^[10] There are six train services, numbered 1 through 6, that each operate from one branch via the city center to another branch or to the Ring Line. All services run every 15 minutes. Each branch, except for theLambertseter Line, has one service that operates to its terminus. Because the lines gradually merge as they near the Common Tunnel, stations close to the city center may be served by multiple numbers.^[11][12][3]

The original section of the metro was theHolmenkollen Line, which opened as asuburban tramway in 1898.^[13][14][15] TheRøa Line was the next to open as a branch, in 1912.^[16] The system became the first Nordic underground railway in 1928, when the underground line to Nationaltheatret was opened.^[17] TheØstensjø Line opened in 1923,^[18] theSognsvann Line in 1934,^[19] and theKolsås Line in 1942.^[20] The opening of the upgraded metro system in the eastern boroughs occurred in 1966, after the conversion of the 1957 Lambertseter Line to metro standard. This involved the implementation ofautomatic train protection, longer platforms, replacement of theoverhead wires withthird rail and removal oflevel crossings. This was followed by the conversion of the Østensjø Line to metro standard, as well as the newGrorud Line and theFuruset Line.^[21] From 1987 to 1993, trains terminated atStortinget, which has since then been the basis for the kilometer markers. In 1993, for the first time, trains ran through the city between the two networks in the Common Tunnel.^[22] The latest extension is the 2006 opening of the Ring Line, which connects the eastern and western network north of the city center.^[10] Between 2006 and 2010, the olderT1000 stock was replaced withMX3000 trains.^[23]

The following table lists the name of each station; the line the station is located on;^[8][9][13] the services (1 through 6);^[3] the date the station opened, and, if applicable, closed;^{[8][9][15][18][24][25]} the average daily number ofboarding passengers in 2001 and 2002 (except for stations on the Ring Line, where the figures are from 2007);^[7][26] the distance fromStortinget;^[8][9] and the grade—whether the station is underground, built-in or above ground (at-grade).^[4] Seven stations function astransfer stations between lines. Seven stations allow transfer to the Oslo Tramway, and two stations allow transfer to thenational rail network.^[3] The list excludes planned stations, but includes former stations that have been closed.
