AB Stockholms Spårvägar


is a name used by two different Swedish limited companies operating public transport in Stockholm, the capital city of Sweden.
The first company was founded in 1915 and owned by the City of Stockholm to coordinate and operate public transport within the City. In 1967 the public transport in the entire Stockholm County was coordinated and the company changed its name to Storstockholms Lokaltrafik and its ownership was transferred to the Stockholm County Council.

Overview

Traffic with horse-drawn trams began in 1877 with the privately owned Stockholms Nya Spårvägsaktiebolag and it gained a concession to operate trams on the streets of Stockholm for 40 years. Largely due to geographic factors, its traffic never extended south of Slussen, although they had the option to do so. Another company, Stockholms Södra Spårvägsaktiebolag was started to provide tramway traffic on Södermalm.
The city-owned text=AB Stockholms Spårvägar was created in 1915 with the aim to coordinate and making the two separate networks more efficient. The network was taken over in 1917 and would follow in 1918. Although the two networks had merged they would not be connected until 1922.
The opening of Västerbron in 1935 caused a major rework of the tram and bus lines when passage through Gamla Stan no longer was mandatory when travelling from Södermalm to Kungsholmen. The first underground parts of the Stockholm Metro opened in 1933 on the stretch from Skanstull to Slussen, although it would be trafficked by suburban trams gaining electricity from overhead wires until special metro vehicles was introduced in 1950 which collected its power from a third rail.
In addition to trams, motorbuses and the metro, SS once operated a large trolleybus system from 1941 until 1964. The Stockholm City Council decided in 1957 to suspend the tramway and the last five lines that remained in the City Centre were closed in conjunction with the switch to right-hand side traffic in September 1967.
The company changed its name from January 1, 1967, to AB Storstockholms Lokaltrafik and is today responsible for public transport in Stockholm County.

In 1987 a new company with the name text=AB Stockholms Spårvägar was created by the Swedish Tramway Society to take care of the traffic on the then forthcoming Djurgårdslinjen. Storstockholms Lokaltrafik accepted the re-use of its old name and logotype. Starting in 1991 the company runs the heritage tram line to the island of Djurgården in central Stockholm.
When regular tram service was started on Spårväg City in 2010 the company got the contract to run this service for the SL.
In April 2014 the Stockholm County Council's Traffic department announced that the company was granted the contract for the period 2015-2022 for both Spårväg City and Lidingöbanan. During this period the two tramways will be connected.
