Sporveisbussene
 AS Sporveisbussene is a bus company that operates about 75% of the routes in Oslo Norway. The company was created in 1997 when the then Oslo Sporveier was reorganised. It is now a subsidiary of Kollektivtransportproduksjon a municipal company responsible for operating public transport in Oslo. In 2003 the Oslo City Council decided that bus transport in Oslo was to be based on public service obligation contracts and Sporveisbussene has steadily lost its routes to these contracts.
