List of Oslo Tramway and Metro operators

The tramway is operated by the subsidiary Sporveien Trikken (previously Oslotrikken), while the metro is operated by Sporveien T-banen (previously Oslo T-banedrift) and the rolling stock is owned by the subsidiary Oslo Vognselskap.

[5] Throughout the history of the Oslo Tramway and Metro, 15 different companies have owned, constructed or operated parts or all of the network.

The first street trams in Oslo were built by three different companies, each with their own network.

The private light rail lines were gradually nationalized and transferred to Oslo Sporveier, which operated the entire network by 1975.

[4] In 2008, Oslo Sporveier merged with its Akershus counterpart, Stor-Oslo Lokaltrafikk, to create Ruter.
