The main manufacturers were Herbrand, Falkenried and Skabo, who delivering a continual stream of stock to the company until 1914. From then until 1925, there was sufficient rolling stock that only ten more vehicles were delivered. KSS decided to convert its lines to electric traction as well. The first electric trams ran on 29 September 1899, and the conversion was completed by 15 January 1900. At the time of electrification, KSS had 57 horsecars; 38 of these were later converted to trailers, while 19 were decommissioned.

Consolidation

After the take-over in 1905, KSS was operating seven routes: Homansbyen–Oslo, Homansbyen–Sannergata, Munkedamsveien–Sannergata–Grefsen, Munkedamsveien–Vålerenga, Sagene – St. Hanshaugen – Kampen, St. Hanshaugen – Rodeløkka and Stortorvet–Vippetangen. KSS extended the Vippetangen Line on 8 November 1905, and opened an extension from Homansbyen to Adamstuen on 24 September 1909. KSS and KES agreed to link their two networks, and a connecting line opened on 1 May 1912 between Homansbyen and Rosenborg station on KES's Line 1. An extension of the Vestbanen Line to Skillebekk was finished on 2 November 1911. This expansion caused the need for more rolling stock, and KSS took delivery of 42 trams from Falkenried and Skabo between 1912 and 1914. At long they were somewhat longer than the other trams. The new lines allowed the two companies to operate on each other's lines, and they introduced a common numbering scheme for the services. Several of the lines were serviced by two numbered routes, a system that remains in use today. From 1912, a number of additional connections were built between the KES and KSS networks, and the two companies started cooperating on certain lines. From 1921 to 1923, KSS bought an additional 22 trams from

It was operated as a shuttle service outside rush hour; during peak hours a direct service was provided to Stortorvet. Part of the main line was double-tracked from Sjømannskolen station to Kastellet station in 1931, to Bråten station in 1940 and to Sæter station in 1946. The line was extended from Sæter to Ljabru station on 17 September 1941, but the extension remained single track until 1967.


Lilleaker Line

The success of the light rail lines tempted KES to extend the Skøyen Line west from Skøyen as a suburban line. The Lilleaker Line opened to Lilleaker station on 9 May 1919, to Avløs station in 1924 and to Kolsås station in 1930. The section west of Jar station is located in the municipality of

After the full line opened, spanning another , Akersbanerne could not reach agreement with Oslo Sporveier, owned by Oslo Municipality. It was not until 1937 that direct services to the city centre were provided via the VÃ¥lerenga Line.


Second World War

The tramways of Oslo experienced a higher ridership and several sabotage actions during the Second World War. During the "April Days of 1940", rumour had it that Oslo was going to be bombed, and the tram service was therefore stopped for half an hour that day. Later, on 19 December 1943, an explosion at the ammunition supply at

had together a ridership of 9.5 billion in 1939, 10.9 billions in 1940, 21 billions in 1943 and at the peak 22.6 billion passengers in 1945. In addition to the regular tram passenger services, Oslo Sporveier started to transport goods across the city in tram wagons. The leadership of the tramway was transferred to the German occupiers, who printed tickets and signs with Nazi emblems on them. If a passenger "demonstrated" by changing his seat when seated next to a German officer, he was expelled at the next stop. Except from damage to the rail tracks at Frøen caused by a bomb, the Oslo Metro experienced no sabotage actions.


Municipalization

The city had granted concessions to the two private tram companies until 1924, after which the city could

Both companies were well run and highly profitable, and on 1 May 1924, KSS and KES were merged and taken over by the city council, which gave the new company the name Kristiania Sporveier ("Kristiania Tramways"). The municipality owned 51 per cent. On 1 January 1925, the city changed its name to Oslo, with the company's name also changing. The light rail lines operated by Holmenkolbanen and Ekebergbanen were not taken over, nor was the Lilleaker Line operated by KES; the city council did not want to take over tram lines in Aker.

The following year, Oslo Sporveier took over Ekebergbanen. In 1975, Oslo Sporveier bought all but a few of the shares in Holmenkolbanen, and at the same time took over operation of all the suburban lines.


Partial closing

The Oslo Tramway had a ridership of 108 million passengers in 1948. On 17 January 1949, the Korsvoll Line became the first tram line to be closed. followed by the Rodeløkka Line on 6 February. The latter reopened following a new route on 2 January 1955. In 1960, with the deregulation of the sale of cars, cheap diesel and the decision to build the metro, the city council decided to close the tram and the trolleybus networks. Tracks would be kept and trams would run until they would be naturally retired. However, no major investments would be made in the lines or rolling stock. Within a year, the Kampen, Rodeløkka, Vippetangen, Simensbråten and Vestbanen Lines were closed, as were trolleybus lines 18 and 24. The remaining two trolleybus routes were closed in 1968.

Although not connected to the metro, the western lines were gradually becoming more like the metro, although they retained overhead wires, a different signaling system and shorter platforms.


Common Tunnel

The western lines terminated at an underground station on the west side of the city centre, while the metro terminated at an underground station at the east side of the city centre. The two termini were located apart. Sentrum station, located in the heart of the city centre, east of Jernbanetorget, opened along with the extension of the metro tunnel in 1977. Water leaks exceeding the drainage capacity forced the station to be closed between 1983 and 1987. When it reopened, the western light rail tunnel had been extended to it, and the station was renamed Stortinget. Because of incompatible signalling and power equipment, it was not possible for trains to run through the whole tunnel. In 1993, the western part of the Common Tunnel and the Sognsvann Line were upgraded to metro standard, followed by the Røa Line two years later. Trains on the Holmenkollen and Kolsås Line needed both
