Geneva Public Transport
The autonomous public transport institution operating most tram, trolleybus and bus services in the canton of Geneva.
Last updated August 26, 2026
Overview
Geneva Public Transport, known in French as Transports publics genevois and commonly abbreviated TPG, is an autonomous public-law institution responsible for most public transport services in the Canton of Geneva, Switzerland. Its network combines electric trams, trolleybuses and conventional buses, and extends beyond the canton through regional and cross-border routes serving neighbouring parts of France. TPG is therefore both a city-region transport operator and an important component of the wider Geneva metropolitan mobility system. The institution is the successor to the Geneva Electric Tramway Company, or Compagnie genevoise des chemins de fer électriques, commonly known as CGTE. CGTE operated tram services in Geneva and surrounding areas, including parts of neighbouring France, from 1900 until the creation of TPG on 1 January 1977. The change established the present public-law structure and placed the principal urban and regional surface network under a cantonally oriented institution. TPG’s service portfolio is organized around three main modes. Trams form the principal high-capacity rail element of the network, linking dense urban districts with suburban corridors. Trolleybuses provide electrically powered, road-based services on selected urban routes, while buses supply the broadest territorial coverage, including local, regional, cantonal, intercantonal and international operations. TPG also operates tpg flex, an on-demand bus service intended to complement scheduled routes where conventional fixed-route service is less suitable. The operator participates in Unireso, the integrated fare system used across much of the Geneva region. Through this arrangement, passengers can use a common ticket across eligible TPG services and selected services provided by partners such as Swiss Federal Railways, SNCF and Mouettes Genevoises Navigation, as well as certain neighbouring French transport services. TPG is consequently part of a coordinated multimodal system rather than an isolated bus and tram operator. Network development has included substantial tramway expansion and experimentation with high-capacity trolleybuses. In the early 2000s, TPG tested a 24-metre double-articulated trolleybus and introduced it into passenger operation on route 10 to Geneva Airport in January 2004. It subsequently acquired ten new double-articulated trolleybuses in 2005–06. Tramway development also accelerated with construction of the Cornavin–Onex–Bernex line, known as TCOB, beginning in 2008 and reaching completion in December 2011. Route restructuring around lines 14 and 18 followed as services to Meyrin, CERN, Carouge and Bernex were adjusted. The institution’s role is primarily regional and public-service oriented. Its principal positioning is dependable, integrated and geographically extensive mobility for Geneva’s urban population, commuters, visitors and cross-border travellers. Passenger rail services within the region are supplied separately by Swiss Federal Railways and SNCF, while lake crossings are operated by Mouettes Genevoises Navigation. TPG’s distinctive scope is its management of the surface urban and regional network, especially the tram, trolleybus and bus services that connect Geneva with its suburbs and neighbouring territories.
History
Geneva Public Transport is the successor to the Geneva Electric Tramway Company, or CGTE, which operated electric tramways in Geneva and parts of neighbouring France from 1900. On 1 January 1977, TPG replaced CGTE as the principal public-law institution responsible for Geneva’s surface public transport. Its creation reflected the organization of the network around a cantonally administered public-service operator rather than a private tramway company. TPG developed a multimodal surface network consisting of trams, trolleybuses and buses. The tram system became the high-capacity backbone, while trolleybuses served important urban corridors and buses provided extensive local, regional and cross-border coverage. The operator also became part of Unireso, the integrated fare system that coordinates eligible journeys across TPG and partner transport services in the Geneva region. Swiss Federal Railways and SNCF provide local rail services, while Mouettes Genevoises Navigation operates passenger ferry services on Lake Geneva; these services are complementary to, rather than operated by, TPG. A notable technological development occurred in December 2003, when TPG began road-testing a 24-metre double-articulated trolleybus manufactured by Hess with electrical equipment from Vossloh Kiepe. The vehicle was created by extending an originally 18-metre single-articulated trolleybus with an additional middle section and could carry approximately 150 passengers. It entered passenger service on route 10 to Geneva Airport in January 2004. In 2005–06, TPG added ten new 24.7-metre double-articulated Hess trolleybuses. By late 2006, the fleet included 92 trolleybuses, all articulated, including eleven double-articulated vehicles. The tram network expanded during the late 2000s and early 2010s. Construction of the Cornavin–Onex–Bernex Tramway, or TCOB, began in 2008 and was completed in December 2011. The project initially supported service patterns associated with line 14 between Bernex and the Meyrin or CERN branches. A line 18 service opened in December 2010 between Avanchet and Coutance and was extended to CERN in May 2011. It was subsequently replaced by line 14 in December 2011, before the tramway was reorganized again in December 2012. The resulting structure separated line 14 between P+R Bernex and Meyrin-Gravière from line 18 between Carouge and CERN. By April 2008, the published network comprised six tram routes, 38 cantonal bus routes, 15 intercantonal or international bus routes and 12 night bus routes. Later descriptions characterize the tram system as the core rail component, with a route length of approximately 55.91 kilometres and about 135 stations. Trolleybus routes have included lines 2, 3, 6, 7, 10 and 19, while the bus network has remained the system’s broadest mode by geographical reach. TPG has also supplemented fixed-route operations with tpg flex, an on-demand bus service designed to extend or complement scheduled public transport. Today, TPG remains the principal surface public transport operator for the Canton of Geneva. Its service area also includes selected destinations in neighbouring France and connections associated with the canton of Vaud. Its history is defined by the transition from CGTE to a public-law institution, the modernization and expansion of Geneva’s tram system, the use of high-capacity trolleybuses, and integration with a cross-border regional fare and mobility framework.

Products and positioning
An integrated, publicly oriented urban and regional mobility provider serving Geneva, its suburbs and selected cross-border destinations through trams, trolleybuses, buses and on-demand transport.
Tram servicesUrban rail transport
TPG’s tram network is the high-capacity rail core of Geneva’s surface transport system. It connects central Geneva with suburban and regional corridors, including destinations such as Meyrin, Bernex, Carouge and CERN. The network has been expanded and reorganized through projects such as the Cornavin–Onex–Bernex Tramway and subsequent line changes.
Trolleybus servicesElectric road transport
Trolleybuses provide electrically powered road transport on selected urban corridors. TPG has operated articulated and double-articulated vehicles, including high-capacity Hess trolleybuses introduced during the 2000s. Published route examples include lines 2, 3, 6, 7, 10 and 19.
Bus servicesUrban, regional and cross-border bus transport
TPG’s bus network supplies the widest geographical coverage in the system. It includes cantonal routes, services connecting with the canton of Vaud, international routes into France and night buses. Buses complement the higher-capacity tram and trolleybus corridors and serve areas that are not directly covered by rail or overhead-electric routes.
tpg flexOn-demand public transport
tpg flex is an on-demand bus service operated by TPG to complement scheduled public transport. It provides a flexible operating model for journeys or areas where a conventional fixed timetable may not be the most suitable form of service.
