The line continued along Bentsebrugata to Torshov, where it intersected with the Grünerløkka–Torshov Line. The line was the first tramway opened by Kristiania Kommunale Sporveie (KKS), on 24 November 1899. Originally the line ran from Athenæum to Sagene Church. The company and the line were taken over by Kristiania Sporveisselskab (KSS) in 1905. The line was expanded on 28 December 1914 with the connection to Torshov. From 1915 Sagene was served by Sagene Ring, a circle line service which combined the Sagene Line with the Grünerløkka–Torshov Line. Operations were taken over by Oslo Sporveier in 1924. From that year until 1949 there was a branch line from Bentsebrugata, the Korsvoll Line. Services on the Sagene Ring terminated in 1957. As part of a planned closing of the tramway, the Sinsen Line from Stortorvet to Sagene was closed in 1966. Services remained from Sagene to Torshov until 1998.

The Common Tunnel (Norwegian: Fellestunnelen), sometimes called the Common Line (Fellesstrekningen), is a 7.3-kilometer (4.5 mi) long tunnel of the Oslo Metro which runs through the city center of Oslo, Norway. The name derives from the fact that all five lines of the metro use the tunnel, which runs from Majorstuen to Tøyen. The section has six stations, including the four busiest on the metro. The tunnel was first built as two separate tunnels which were later connected. The Holmenkolbanen company opened the western section of the tunnel from Majorstuen via Valkyrie plass to Nationaltheatret in 1928. In 1966, the Oslo Metro opened, including the tunnel from Tøyen via Grønland to Jernbanetorget. In 1977, the eastern end was extended to Sentrum, but the extension was closed in 1983 because of water leakages. In 1987, the Sentrum station reopened as Stortinget, and became the terminus of both the western and eastern lines. By 1993, the western end had been upgraded to metro standard, Valkyrie plass was closed, and the first trains ran through the whole tunnel. The section from Tøyen to Brynseng, although not completely located within the tunnel, is considered part of the Common Line. At Majorstuen, the line splits into three; the Røa Line, the Holmenkollen Line and the Sognsvann Line. At Tøyen, the line splits into the Lambertseter Line and the Grorud Line. The tunnel is the bottleneck of the metro, allowing 24 trains per hour in each direction west of Stortinget, and 28 east of Stortinget.

Karl Johans gate is the main street of the city of Oslo, Norway. The street was named in honor of King Charles III John, who was also King of Sweden as Charles XIV John.Karl Johans gate is a composite of several older streets that used to be separate thoroughfares. The eastern section was part of Christian IV's original city near the ramparts surrounding the city. When the ramparts were removed to make way for Oslo Cathedral, three separate sections eventually became Østre Gade. The wider western section was built during the 1840s as an avenue connecting the newly erected Norwegian Royal Palace with the rest of the city. In 1852, it was named Karl Johans gate in honor of the recently deceased king. His equestrian statue, by sculptor Brynjulf Bergslien, was later erected during 1875 in front of the Royal Palace. When the Norwegian parliament building was completed in 1866 at the junction of the two formerly separate streets, the two streets were joined and the whole length was named Karl Johans gate. In its current route, it connects Oslo Central Station, the main railroad station in Oslo, and the Royal Palace. The route changes its direction and width slightly halfway between these two points, at Egertorget, a square at the intersection of Karl Johans gate and Øvre Slottsgate. This is the highest point and, here, both ends of the street may be seen. The street is 1,020 metres long; in addition there are 300 metres of direct extensions, Palace Hill (Slottsbakken) and Palace Place (Slottsplassen). The street includes many of Oslo's tourist attractions: In addition to the Royal Palace, Central Station and Stortinget, there are the National Theatre, the old University Buildings, the Palace Park and the pond ("Spikersuppa") at Eidsvolls plass, which serves as a skating rink in winter. Oslo Cathedral's lower end is surrounded by the Bazaar Market (Basarene ved Oslo domkirke), which is integrated with the historic Fire Watch (Brannvakta) that served as Oslo's main fire station from 1860 until 1939.
