Trolley may refer to:
A tram is a train that runs on a tramway track on public urban streets; some include segments on segregated right-of-way. The lines or networks operated by tramcars as public transport are called tramways or simply tram/streetcar. 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.
Light rail transit (LRT) is a form of passenger urban rail transit characterized by a combination of tram and metro features. While its rolling stock is more similar to a traditional tram, it operates at a higher capacity and speed, and often on an exclusive right-of-way. In many cities, light rail transit systems more closely resemble, and are therefore indistinguishable from, traditional underground or at-grade subways and heavy-rail metros.
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.
A cart or dray is a vehicle designed for transport, using two wheels and normally pulled by one or a pair of draught animals. A handcart is pulled or pushed by one or more people.
Conservation and restoration of rail vehicles aims to preserve historic rail vehicles.
A trackless train — or tram, road train, land train, or parking lot train is a road-going articulated vehicle used for the transport of passengers, comprising a driving vehicle pulling one or more carriages connected by drawbar couplings, in the manner of a road-going railway train. Similar vehicles may be used for transport of freight or baggage for short distances, such as at a factory or airport.
A trolley pole is a tapered cylindrical pole of wood or metal, used to transfer electricity from a "live" (electrified) overhead wire to the control and the electric traction motors of a tram or trolley bus. It is a type of current collector. The use of overhead wire in a system of current collection is reputed to be the 1880 invention of Frank J. Sprague, but the first working trolley pole was developed and demonstrated by Charles Van Depoele, in autumn 1885.
Urban rail transit is an all-encompassing term for various types of local rail systems providing passenger service within and around urban or suburban areas. The set of urban rail systems can be roughly subdivided into the following categories, which sometimes overlap because some systems or lines have aspects of multiple types.
Various terms are used for passenger railway lines and equipment; the usage of these terms differs substantially between areas:
Guided Light Transit is the name of guided bus technology and associated infrastructure designed and manufactured by Bombardier Transportation. It has been installed in two French cities: Nancy and Caen. As of 2018, only the Nancy system is in operation; the Caen system has been abandoned and now rebuilt as a conventional tramway by 2019.
A horse-drawn vehicle is a mechanized piece of equipment pulled by one horse or by a team of horses. These vehicles typically had two or four wheels and were used to carry passengers and/or a load. They were once common worldwide, but they have mostly been replaced by automobiles and other forms of self-propelled transport.

Ground support equipment (GSE) is the support equipment found at an airport, usually on the apron, the servicing area by the terminal. This equipment is used to service the aircraft between flights. As the name suggests, ground support equipment is there to support the operations of aircraft whilst on the ground. The role of this equipment generally involves ground power operations, aircraft mobility, and cargo/passenger loading operations.
With five different modes of transport the San Francisco Municipal Railway runs one of the most diverse fleets of vehicles in the United States. Roughly 500 diesel-electric hybrid buses, 300 electric trolleybuses, 250 modern light rail vehicles, 40 historic streetcars and 40 cable cars see active duty.
Although tram systems date to the late 19th and early 20th centuries, many old systems were closed during the mid-20th century because of the advent of automobile travel. This was especially the case in North America, but postwar reductions and shutdowns also occurred on British, French and other Western European urban rail networks. However, traditional tramway systems survived, and eventually even began to thrive from the late 20th century onward, some eventually operating as much as when they were first built over a century ago. Their numbers have been augmented by modern tramway or light rail systems in cities which had discarded this form of transport.
Electric current collectors are used by trolleybuses, trams, electric locomotives or EMUs to carry electrical power from overhead lines or electrical third rails to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for third rails are mounted on the bogies. Current collectors are also electric bridging components that collect electrical current generated at the electrodes of electrochemical devices, such as lithium-class battery cells, and connect with external circuits.
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 Federal District authority, Secretaría de Transportes y Vialidad, 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.
High-floor describes the interior flooring of commuter vehicles primarily used in public transport such as trains, light rail cars and other rail vehicles, along with buses and trolleybuses. Interior floor height is generally measured above the street surface or above the top of the rail. High-floor designs usually result from packaging requirements: mechanical items such as axles, motors, crankshafts, and/or transmissions, or luggage storage spaces are traditionally placed under the interior floor of these vehicles. The term is used in contrast with low-floor designs, which offer a decreased floor and entry height above the street surface. Since low-floor designs generally were developed after high-floor vehicles, the older high-floor design is sometimes also known as conventional or the “traditional” design.
