 in 1909, Oslo had relied on the Oslo Tramway since 1875. But in 1927 Oslo Sporveier started their first bus route, and September 28, 1931, they sent an application for operation of a trolleybus in Oslo between Oslo and Grorud

But while the City Council of Aker wanted the other solution, and was pressing Oslo Sporveier to go to Skøyen, and the Norwegian National Road Administration felt that if Oslo Sporveier wanted to build a trolleybus route to Grorud, they would have to pay for part of the upgrade of Trondheimsveien, a term not acceptable for the company.
