The rolling stock of Oslo Metro, Norway, has consisted of three classes: T1000/T1300, T2000 and MX3000. The T1000 was built as 162 single cars from 1964 to 1978. From 1979 to 1985, 33 new T1300 trains were built, followed by the conversion of 16 T1000s. Six two-car T2000 units were delivered in 1994. Since 2005, the first 83 three-car MX3000 units have been replacing the older stock, and the last T1000 was retired in 2007. From 2010, only MX3000-trains are in use. The T1000/T1300 and T2000 were built by Strømmens Værksted, with motors from Norsk Elektrisk & Brown Boveri (NEBB) and AEG, respectively, and the MX3000 were built by Siemens.
All trains receive 750 V DC from a third rail shoe, while the T1300 and T2000 also have pantographs. This allows the latter to also operate on the suburban lines of the Oslo Tramway, which the western part of the current metro was part of until 1995. All trains feature automatic train protection and step-free access from the platforms. Trains can operate up to six cars in length. The T1000/T1300 and MX3000 are capable of 70 kilometres per hour (43 mph), while the T2000 can operate at 100 kilometres per hour (62 mph). The T2000 introduced articulated cars, while the MX3000 introduced regenerative brakes and air conditioning. The T1000/T1300 and MX3000 can be run in multiple with each other, but not with the T2000. The MX3000 replaced the red color scheme with a white livery.
