A trolleybus is an electric bus that draws power from dual overhead wires using spring-loaded trolley poles. Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole. They are also distinct from other kinds of electric buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there are exceptions.
Servicio de Transportes Eléctricos de la Ciudad de México (STE) is a public transport agency responsible for the operation of all trolleybus and light rail services in Mexico City. As its name implies, its routes use only electrically powered vehicles. It was created on 31 December 1946 and is owned by the Mexico City government. STE is overseen by a broader local governmental authority, Secretaria de Movilidad de la Ciudad de México (SEMOVI)(Secretariat of Mobility of Mexico City), formerly (SETRAVI) which also regulates the city's other public transport authorities, including Sistema de Transporte Colectivo, Red de Transporte de Pasajeros del Distrito Federal and Metrobús, as well as other forms of transportation in the district. STE's passenger vehicle fleet consists exclusively of trolleybuses, light rail, and aerial lift vehicles, and in 2007 its network carried 88 million passengers, of which 67 million were on trolleybus services and 21 million on light rail.
The Mexico City trolleybus system serves Mexico City, the capital city of Mexico, and is operated by Servicio de Transportes Eléctricos.
The Ashgabat trolleybus system formed part of the public transport network in Ashgabat, the capital city of Turkmenistan. It was the only trolleybus system ever in that country.
The Coimbra trolleybus system formed part of the public transport network in the city of Coimbra, Portugal. Opened in 1947, it supplemented, and then eventually replaced, the Coimbra tramway network. Service was suspended in March 2021 because of road construction, and officials stated that the suspension was temporary, but in late 2022 the mayor indicated that any resumption of trolleybus service would not occur until after completion of construction of a new Bus Rapid Transit line, around late 2024. However, in July 2024, the city council voted not to resume service – to make the suspension a permanent closure – albeit with a proposal floated for a future tourist trolleybus operation along the banks of the Mondego River, without further detail given.
The Philadelphia trolleybus system forms part of the public transportation network serving Philadelphia, in the state of Pennsylvania, United States. It opened on October 14, 1923, and is now the second-longest-lived trolleybus system in the world. One of only four such systems currently operating in the U.S., it presently comprises three lines and is operated by the Southeastern Pennsylvania Transportation Authority (SEPTA), with a fleet of 38 trolleybuses, or trackless trolleys as SEPTA calls them. The three surviving routes serve North and Northeast Philadelphia and connect with SEPTA's Market–Frankford rapid transit line.
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.
Vétra, or more formally the Société des Véhicules et Tracteurs Electriques, was a French manufacturer of trolleybuses and electric locomotives. Founded in 1925, it became one of Western Europe's largest builders of trolleybuses during the middle decades of the 20th century, making in excess of 1,750 vehicles, for cities in France and in several other countries. The company ceased production in 1964.
The Nakhchivan trolleybus system was a network of trolleybus routes that formed part of the public transport system in Nakhchivan, the capital of the eponymous Nakhchivan Autonomous Republic of Azerbaijan, for nearly 20 years from 1986.
