MX3000
MX3000 is an electric train used on Oslo Metro in Oslo, Norway. The multiple units are produced by Siemens Mobility, who started serial delivery in 2007. Seventy-eight three-car units were ordered by Sporveien, and five by Akershus County Municipality. They replaced the older T1000 and T1300 stock that was used on the Oslo Metro since 1966. By 2010, the last T1000 and T1300 trains had been retired and replaced by 83 three-car units. 32 additional sets were ordered, and the final train set was delivered in 2014, increasing the fleet to 115 units. The trains are built as 3-car units, though they often operate 2 coupled units in regular service. The units are long, and weigh empty. They have twelve traction motors, allowing speeds of . Seated capacity is 138 seats, and total capacity is 493 passengers. The first series of 33 units were ordered in 2003, followed by an additional order for 30 in 2005, 15 in 2008, and 32 in December 2010. Financed by Oslo Package 2, each unit cost ...

Oslo Metro
The Oslo Metro ( no, Oslo T-bane or or simply ) 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 , serving 101 stations of which 17 are underground or indoors. In addition to serving 14 out of the 15 boroughs of Oslo, two lines run to Kolsås and Østerås, in the neighboring municipality of Bærum. In 2016, the system had an annual ridership of 118 million. 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 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. All the trains are operated with MX3000 stock. These replaced the olde ...

Østensjø Line
The Østensjø Line ( no, Østensjøbanen) is a line on the Oslo Metro which runs from Brynseng to Mortensrud. It further shares track with the Lambertseter Line along the section from Tøyen to Brynseng. The line runs through the primary residential areas of Bøler, Østensjø and Søndre Nordstrand. The line is served by Line 3 of the metro. The first section of the line was built by Akersbanerne as part of the Oslo Tramway and connected to the Vålerenga Line at Etterstad. The first section, to Bryn, opened on 18 December 1923, and was extended to Oppsal in January 1926. Services were variously provided by Kristiania Sporveisselskab, Bærumsbanen and Oslo Sporveier. Proposals for making the line part of the metro arose in the late 1940s and the system was approved in 1956. This materialised in an extension of the line to Bøler on 20 July 1958. The Østensjø Line became the third line of the metro on 26 November 1967, the same day the line was extended to Skullerud. The l ...

Lambertseter Line
The Lambertseter Line ( no, Lambertseterbanen) is a line on the Oslo Metro which runs from Brynseng to Bergkrystallen. It further shares track with the Østensjø Line along the section from Tøyen to Brynseng. The line runs through a primary residential area of Nordstrand, serving neighborhoods such as Manglerud, Ryen and Lambertseter. The line is served by Line 4 of the metro, which runs every fifteen minutes. This is supplemented by Line 1 that is extended to Bergkrystallen between 6:30 and 19 on weekdays, giving a combined frequency of eight trains per hour. Originally the Lambertseter Line was proposed as an extension of the now closed Simensbråten Line. Planning of a metro started in 1946 and instead of running via Ekeberg the Lambertseter Line was to run via Etterstad. Construction was tied with large-scale construction of housing along the route. As the Lambertseter Line could be completed much earlier than the metro's Common Tunnel, the Lambertseter Line was f ...

OS T1000
T1000 and T1300 were two rapid transit train classes used on Oslo Metro in Oslo, Norway. The 197 cars were built by Strømmens Verksted, Norsk Elektrisk & Brown Boveri and AEG between 1960 and 1981. They were the first metro trains used in Oslo, and had remained in active use until being replaced by OS MX3000 trains in 2007. Each car was equipped with a driver's cab at one or both ends and four motors, each with . The cars were long, wide and tall. The trains used 750 V current, and were capable of . Signaling was provided through automatic train protection. In 1960, two less powerful T single-car units were built, designed to be prototypes used on the Oslo Tramway. After a one-year trial, they were put into scheduled traffic to the KolsÃ¥s Line, where they remained in regular service until 1983. The production series was somewhat different in design and performance. T1000 was both used to refer to the class as a whole, or the first 162 cars, that are only equipped wit ...

Grorud Line
The Grorud Line ( no, Grorudbanen) is a line on the Oslo Metro between Tøyen and Vestli in Oslo, Norway. Built as a mix of underground, at ground level and as an elevated line, it runs through the northern part of Groruddalen, serving such neighborhoods as Grorud, Romsås and Stovner. Line 5 runs along the entire line four times per hour. Line 4 runs between Vestli and Økern before branching off on the Løren Line to get onto the Ring Line. With 40,000 daily riders, the Grorud Line is the busiest branch of the metro. Proposals for an urban railway through the upper parts of Groruddalen were first articulated in public documents in 1919. Planning started in the late 1940s and the line was politically approved in 1954, along with three other metro lines and the Common Tunnel. Construction started in 1956 and was part of a process to transform Groruddalen into a residential area. The first part of the Grorud Line, from Tøyen to Grorud, was opened on 16 October 1966. The r ...

Oslo Package 2
The Oslo Package 2 ( no, Oslopakke 2) or O2 is a political agreement for financing investments in public transport in Oslo and Akershus, Norway. The program ran from 2001 to 2011, and includes many large and small investments in railways, the Oslo Tramway, the Oslo Metro and infrastructure for buses. Total budget is . The project is a cooperation between the transit authorities Oslo Sporveier and Stor-Oslo Lokaltrafikk, Oslo Municipality and Akershus County Municipality, and the government agencies of the Norwegian National Rail Administration and the Norwegian Public Roads Administration. Large infrastructure projects include the Ring Line of the metro, along with new MX3000 rolling stock, and the new Asker- and Follo Lines of the national railways.

Bergkrystallen (station)
Bergkrystallen is the end station on the Lambertseter Line, after Munkelia, of the Oslo Metro. It is located in the Nordstrand borough. Bergkrystallen is a road just north of the station. The area is mainly residential. Originally it was planned to extend the Lambertseter Line to Mortensrud, but the Østensjø Line was extended instead. The station is served by Line 4. Bergkrystallen was opened as the end stop of the Lambertseter tram line in 1957, it was upgraded to a subway station in 1966. Although the subway system was formally opened by the king at Jernbanetorget on 22 May 1966, the king and mayor travelled the line to Bergkrystallen where there was a ceremonial bouquet presentation in front of a large audience. The building of more residential apartments on the station has met local resistance. In 2007, a proposal was made to build some terraced housing and a kindergarten on the station.

Insulated-gate Bipolar Transistor
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure. Although the structure of the IGBT is topologically the same as a thyristor with a "MOS" gate ( MOS-gate thyristor), the thyristor action is completely suppressed, and only the transistor action is permitted in the entire device operation range. It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs), electric cars, trains, variable-speed refrigerators, lamp ballasts, arc-welding machines, induction hobs, and air conditioners. Since it is designed to turn on and off rapidly, the IGBT can synthesize complex waveforms with pulse-width modulation and low-pass filters, so it is also used in switchi ...
