Ullevål Hageby Line

The Ullevål Hageby Line (Norwegian: Ullevål Hageby-linjen) is a light rail section of the Oslo Tramway. It runs from Stortorvet in the city center of Oslo, Norway to Rikshospitalet. It passes through the areas of St. Hanshaugen, Ullevål Hageby and Blindern before reaching Gaustad. It serves major institutions such as Oslo University College, Bislett Stadion, Ullevål University Hospital, the University of Oslo and Rikshospitalet. The line is served by route 17 and 18 by Oslo Sporvognsdrift using SL95 trams, while the tracks are owned by Kollektivtransportproduksjon.

The first section, from Stortorvet from Homansbyen, opened in 1875 as a horsecar line. It was electrified in 1900, and extended to Adamstuen in 1909. In 1925, the line reached Ullevål Hageby. The final extension to Rikshospitalet was opened in 1999, following the move of the hospital. The last section is formally called the Gaustad Line (Gaustadlinjen). North of Adamstuen, the line runs in its own right-of-way, mostly in the center of streets; southwards, it is a street tramway. Transfers to the Oslo T-bane are possible at Forskningsparken and Tinghuset/Professor Aschehougs gate.
