History

During the latter part of the 1980s, interest in tramway transportation grew in the Stockholm area, with various proposals emerging from both public and private sectors. One notable group, dubbed the "Tvärspårvägsgruppen" (Cross-tramway Group), comprising Asea, Skanska, VBB, and the transport consultancy firm Transek, along with PKbanken and

conducted a tramway investigation, prioritising the "Horseshoe Line" as the most economically viable route. However, during the planning phase, negotiations for the "Dennis package" an agreement for investments in rail and road infrastructure in Stockholm County, occurred simultaneously with regional infrastructure planning. The agreement reached in September 1992 only included the Horseshoe Line, now referred to as the "Snabbspårvägen" (Express Tramway). Consequently, it was incorporated into the regional plan of 1991, with land reserved in the Stockholm comprehensive plan for the line. Construction of the Tvärbanan (Cross Tramway) began in 1996, with the segment between Gullmarsplan and Liljeholmen opening for traffic in January 2000, followed by an extension to Alvik later that year. This extension marked the first new North-South connection across lake

in Stockholm in approximately 40 years. Another extension from Gullmarsplan to Sickla Udde in Hammarby Sjöstad opened in August 2002, facilitating efficient interchange with suburban trains from the south upon the opening of the Årstaberg station in January 2006. The initial funding covered the Alvik-Gullmarsplan section, but financing for subsequent segments was anticipated to be resolved by 1996. However, no funding solution materialised, and the agreement dissolved in February 1997. Despite this setback, construction progressed, and in 2009, the expansion of Tvärbanan's Solna Branch commenced. This new section from Alvik to Solna Centrum opened in 2013, with the final stretch to Solna Station completed in August 2014. Critics highlighted the high costs and technical standards of the Alvik-Solna section, which exceeded initial estimates. Nevertheless, the Tvärbanan's positive impact on commuting, especially in areas like Hammarby Sjöstad and Årstadal, led to increased frequency being required, improving from a 10-minute to a 7.5-minute service during peak hours. From 2013 to 2017, the Tvärbanan operated as two separate lines, both designated as Line 22, with interchange available at Alvik. However the original signalling system was replaced between Sickla Udde and Alvik in 2017, with entire line reopening in August 2017 for through-traffic at Alvik. The first section Kista branch, connecting Norra Ulvsunda to Bromma Airport, commenced operations in May 2021 as Line 31, with a further extension to

The line runs on the same track as line 30 except for the branch to Bromma Airport itself. The nearby Bromma Blocks shopping centre is served with a new stop as well. Via the Tranebergstunnel north of Alvik there is a track connection with the metro and Brommadepån, which is shared with the

Main interchange options


Rolling stock

Tvärbanan is served by tram types designated A32 and A35. The A32, Flexity Swift from Bombardier, began operating the Tvärbanan with the start in 1999. The A35, Urbos AXL from CAF was introduced in connection with the extension to Solna in October 2013. Both types are approximately 30 meters long and have 72–78 seats each, with two trams usually coupled to increase capacity, leading to a train of around 60 meters long. This compares to the 140 meter metro trains and the 214 meter commuter trains. The trams are operated by a driver. Until June 2016, there was also a conductor on board for ticket validation. These are today replaced with ticket validators located at all stops.


Signalling system

A signalling system monitors and controls the movements of rolling stock on a rail network to ensure safe operation. Tvärbanan previously suffered from a long-standing issue of incompatible and low performing rail signalling systems. The Tvärbanan network featured multiple different signalling systems from different vendors, because when the rail line was built, the signalling systems were tendered separately for each construction stage. A visible example of this was at the Alvik station, which was a break point between two systems. Even though the line runs straight at Alvik, the same train could not be run past the station because of the incompatibility of the systems. Passengers had to switch trains there. The section south of Alvik was closed during the summer of 2017 to upgrade the signalling.

was needed in order for the trams to be able to run past the airport. In cold weather, sparks arise from the trams' overhead contact line, which could disrupt radio signals in the air traffic control tower at Bromma Airport. Tests needed to be carried out in sub-zero temperatures to gain approval for traffic. The first part of the new branch opened on 17 May 2021, with trams running on Line 31 between Alviks strand and Bromma flygplats.
