A tram is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with trolley being the preferred term in the eastern US and streetcar in the western US. Streetcar or tramway are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the United States, the term tram has sometimes been used for rubber-tired trackless trains, which are unrelated to other kinds of trams.
A tram-train is a type of light rail vehicle that meets the standards of a light rail system, but which also meets national mainline standards permitting operation alongside mainline trains. This allows services that can utilise both existing urban light rail systems and mainline railway networks and stations. It combines the urban accessibility of a tram or light rail with a mainline train's greater speed in the suburbs.
Guided buses are buses capable of being steered by external means, usually on a dedicated track or roll way that excludes other traffic, permitting the maintenance of schedules even during rush hours. Unlike trolleybuses or rubber-tired trams, for part of their routes guided buses are able to share road space with general traffic along conventional roads, or with conventional buses on standard bus lanes.
Guided Light Transit was the name of guided bus technology and associated infrastructure designed and manufactured by Bombardier Transportation. It was installed in two French cities: Nancy and Caen. The Caen system was closed in 2017 and replaced by conventional trams, while the Nancy system was closed in March 2023 and is to be replaced by trolleybuses.
Europe has an extensive number of tramway networks. Some of these networks have been upgraded to light rail standards, called Stadtbahn in Germany, premetros in Belgium, sneltram in the Netherlands, elétrico in Portugal and fast trams in some other countries.
Translohr is a rubber-tyred tramway system, originally developed by Lohr Industrie of France and now run by a consortium of Alstom Transport and Fonds stratégique d'investissement (FSI) as newTL, which took over from Lohr in 2012. It is used in Paris and Clermont-Ferrand, France; Medellín, Colombia; Tianjin and Shanghai, China; and Venice-Mestre and Padua in Italy. In June 2012, Alstom Group and the Strategic Investment Fund acquired Translohr for €35 million.
The Leipziger Verkehrsbetriebe (LVB), literally translated into English as the Leipzig Transport Authority, operates the tramway and bus transport services in Leipzig, Germany. The LVB network is a part of the regional public transport association, the Mitteldeutscher Verkehrsverbund (MDV). The LVB was formed by the merger, from 1 January 1917, of two predecessor undertakings, the Großen Leipziger Straßenbahn and the Leipziger Elektrischen Straßenbahn. The merged undertaking was also known as GLSt until it was reorganized and renamed as the LVB, from 29 July 1938.
Verkehrsbetriebe Zürich (VBZ) is a public transport operator in the Swiss city of Zürich, and is wholly owned by the city. Previously known as the Städtische Strassenbahn Zürich (StStZ), the organisation was founded in 1896 and adopted its current name in 1950.
Trams make an important contribution to public transport in the city of Zürich in Switzerland. The tram network serves most city neighbourhoods, and is the backbone of public transport within the city, albeit supplemented by the inner sections of the Zürich S-Bahn, along with urban trolleybus and bus routes, as well as two funicular railways, one rack railway and passenger boat lines on the river and on the lake. The trams and other city transport modes operate within a fare regime provided by the cantonal public transport authority Zürcher Verkehrsverbund (ZVV), which also covers regional rail and bus services.
A rubber-tyred tram is a development of the guided bus in which a vehicle is guided by a fixed rail in the road surface and draws current from overhead electric wires.
Trams in France date from 1837 when a 15 km steam tram line connected Montrond-les-Bains and Montbrison in the Loire. With the development of electric trams at the end of the 19th century, networks proliferated in French cities over a period of 15 years. Although nearly all of the country's tram systems were replaced by bus services in the 1930s or shortly after the Second World War, France is now in the forefront of the revival of tramways and light rail systems around the globe. Only tram lines in Lille and Saint-Étienne have operated continuously since the 19th century; the Marseille tramway system ran continuously until 2004 and only closed then for 3 years for extensive refurbishment into a modern tram network. Since the opening of the Nantes tramway in 1985, more than twenty towns and cities across France have built new tram lines. As of 2020, there are 29 operational tram networks in France, with 3 more planned. France is also home to Alstom, a leading tram manufacturer.
The Nancy Guided Light Transit or TVR was a guided bus system in Nancy, France. The system used Bombardier's TVR technology. The TVR replaced the trolleybus system in Nancy. The system was closed on 12 March 2023, and is to be replaced by conventional trolleybuses.
The Fribourg trolleybus system forms part of the public transport network in Fribourg, capital of the canton of Fribourg, Switzerland. The system also serves the neighbouring municipalities of Villars-sur-Glâne and Givisiez, using one line in each case.
The Zürich trolleybus system is part of the public transport network of Zürich, Switzerland. Opened in 1939, it combines the Zürich S-Bahn, the Zürich tramway network and Zürich's urban motorbus network to form an integrated all-four style scheme.
The Caen tramway is a tram in the city of Caen, France. The tram opened on 27 July 2019 and replaced the Caen Guided Light Transit (TVR) that closed in December 2017. The tramway uses the same route as the TVR, with a short new branch to Presqu'île and a with a new tram depot in Fleury-sur-Orne.
