(KES) established a tramway from the city center to

in 1894. Four years later, fund-raising started to build the Aker Avenue towards Smestad, but the recession made fund-raising difficult. The plans were launched again in 1904, and subsequently revised in 1908, by which time they including a tramway along the avenue. In 1910, A. S. Guldberg, Iver Lycke, W. Munthes-Kaas and H. A. Mørk applied for a

to build a tramway along the route. This was granted by the municipal council in Aker on 26 May. The four individuals then transferred their rights to the municipality, who started negotiating rights with KES, and Holmenkolbanen—the latter who had a suburban tramway running from Majorstuen, the Holmenkollen Line. An arrangement was made with Holmenkolbanen, where the municipality would

the necessary land and build the bed, while Holmenkolbanen would lay the tracks, the wires and operate the trams. The line would remain owned by the company A/S Smedstadbanen, which was again owned by Aker Municipality. The agreement had a duration of 50 years, but the municipality retained the right to purchase the line if work to extend the line from Majorstuen through the Common Tunnel to the city center had not started by 1917, or had not been completed by 1922. Government approval was granted on 7 July 1911, and the construction was completed on 7 November 1912. The long line was single tracked, with

and Smestad, which were the only stations in addition to Majorstuen. Holmenkolbanen used a single tram, with departures every 20 minutes. There were extra departures from Borgen to Majorstuen during the afternoon rush-hour.

Nationaltheatret expansion

The process of extending the Holmenkollen Line from Majorstuen to the city center had started in 1901. The process had been delayed several times because of disagreements between the city and the company, in part because the two could not agree if it should be classified as a railway or a tramway. Construction started in 1912, but stopped again in 1914 because the municipality and the company could not agree on the location of the

. The municipality wanted it at Ruseløkkveien, but this would make it difficult for the company to build the tunnel through the city center to connect to the suburban tramways east of the city center. Construction was stopped in October 1914. The following year, the municipality launched a contest to make the best suggestion for the tram networks. It took five years to select a winner, and this allowed the municipality and company to make a compromise by locating the terminus at Nationaltheatret. But not until 1926 was permission granted for the station. Construction commenced that year and the station and tunnel opened in 1928. When the tunnel had not been completed by 1922, Aker Municipality decided to purchase the line. At the time, the municipality was planning to start its own tram company, Akersbanerne, and the Smestad Line was considered as part of the network, along with the planned Sognsvann Line. But delays caused the Sognsvann Line not to open until 1934. The take-over caused a disagreement between the two companies about payment for the common section, which would still be owned by Holmenkolbanen. Not until 1932 was the issue resolved. The investments had drained Holmenkolbanen, particularly after it had received a massive lawsuit for damage to adjacent properties during the tunneling. After the issue had been resolved by the

Røa extension

In the 1920s, the area towards

experienced a growth in housing. Akersbanerne proposed in 1931 to the municipal council that the Smestad Line be extended towards Makrellbekken. Government permission was granted on 26 May 1933, and construction started the same year. The extension was built with single track. When the line was taken over by Holmenkolbanen, the new owner suggested extending the line to

. Government permission was granted in on 29 June 1934, and construction started immediately. The extension opened on 24 January 1935. The new line was initially not profitable, because Schøyens Bilcentraler had kept its concession to operate buses in the area. Not until

on the Lilleaker Line to Sørbyhaugen on the Røa Line. The construction was delayed because a bridge needed to be built across Mærradalen, and the company ran out of money, and construction stopped for nine months in 1940. The line was opened on 15 June 1942, and the section from Sørbyhaugen to Kolsås was renamed the Kolsås Line. This resulted in two companies operating from Sørbyhaugen to Nationaltheatret, but an agreement was made where only Holmenkolbanen's tickets were sold on the section, so all revenue went to that company, regardless of the train's operator. The Kolsås Line operated every fifteen minutes along the Røa Line part.

Bærum extensions

Proposals to extend the line into the neighboring municipality of Bærum had first been launched in 1919. In 1941, construction of an extension to

started. The main problem was getting building materials for a bridge to cross Grinidammen, and a local disagreement about where the station at Røa was to be located. The extension was opened on 22 December 1948, after Røa Station had been moved, and the line put in a short tunnel under the center of Røa. The extension via Eiksmarka to Lijordet opened on 3 December 1951. Lijordet was intended to be named Sørbråten, but there was already a station with that name on the

The ownership of the line was gradually taken over by the municipality through

. In 1975, most of the shares were bought, along with those that Oslo Sporveier had received as part of the municipal merger with Aker in 1948. Gradually during the 1970s and 1980s, Holmenkolbanen became more integrated into Oslo Sporveier, including the two using the same rolling stock, tickets and uniforms. Oslo Sporveier upgraded the line in the last half of the 1970s, laying new

, upgrading the tracks to higher weight and purchasing new trams. Plans to have trams run through the city center have existed since 1919. In the late 1940s, Holmenkolbanen revised the plan, and proposed extending the Common Tunnel eastwards. From 1951, the municipality started working on plans for the Oslo Metro in the eastern part of the city. The large difference in traffic between the eastern and western lines caused the plans to be changed during the 1960s, and the eastern network was equipped with

The Sognsvann Line was upgraded to metro standard and reopened on 3 April 1993. The Røa Line was closed on 5 February 1995 to be upgraded to metro standard. The upgrades meant that all platforms needed to be extended to to allow six-car metro trains. The only exception was Østerås, that was made only long enough for five cars, although this could easily be extended later. The upgrade involved a complete renovation of the tracks, with the old ones being replaced with new, and increasing the weight to 49 kilograms per meter (33 lb/ft). The overhead wire was replaced with a third rail; this required all four level crossings, at Makrellbekken, Hovseter, Eiksmarka and Ekraveien, to be replaced. In the former three, the track was sunk under the level of the road, requiring several hundred meters of the line to be rebuilt. Pedestrian underpasses were built at Ekreveien, Borgen, Holmen, Huseby skole and Lijordet. Three stations were closed: Grini, Huseby skole and Heggeli. Volvat kept the two-car length, and was no longer served by the Røa Line, only the Kolsås Line. To compensate for the closing of Huseby skole, Røa was moved back to it original position, causing a heated local debate. The signaling system was replaced with the

, where twelve people were injured. During the upgrade, the area along the line was served by buses. Bus stops could only be established at places where cars could pass, making it difficult to place stops at Røa and Sørbyhaugen. Passengers transferring to the Kolsås Line would normally have 15 minutes longer travel time, and congestion caused delays of up to 30 minutes. This caused more people to use cars, which increased the congestion further. Ridership on the buses was significantly lower than on the rail. The Kolsås Line opened on 20 August and the Røa Line on 19 November. After the opening, the line connected with the

as Line 2, and started being served by T1000 trains. The Røa Line, including the common section in the city center, has been extended eight times, more than any other line of the
