Trolleybus
A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tramin the 1910s and 1920sJoyce, J.; King, J. S.; and Newman, A. G. (1986). ''British Trolleybus Systems'', pp. 9, 12. London: Ian Allan Publishing. .or trolleyDunbar, Charles S. (1967). ''Buses, Trolleys & Trams''. Paul Hamlyn Ltd. (UK). Republished 2004 with or 9780753709702.) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) using spring-loaded or pneumatically raised trolley poles. Overhead line#Parallel overhead lines, 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 (or pantograph (transport), pantograph). They are also distinct from other kinds of Battery electric bus, electric buses, which usually rely on Automotive battery, batteries. Power is most commonly supplied as 600-volt ...

Electric Bus
An electric bus is a bus that is propelled using electric motors, as opposed to a conventional internal combustion engine. Electric buses can store the needed electrical energy on board, or be fed mains electricity continuously from an external source such as overhead lines. The majority of buses using on-board energy storage are battery electric buses (which is what this article mostly deals with), where the electric motor obtains energy from an electric vehicle battery, onboard battery pack, although examples of other storage modes do exist, such as the gyrobus that uses flywheel energy storage. When electricity is not stored on board, it is supplied by contact with outside power supplies, for example, via a current collector (like the trolley pole, overhead conduction poles in trolleybuses), or with a ground-level power supply, or through Inductive charging#Dynamic charging, inductive charging. As of 2017, 99% of all battery electric buses in the world have been deployed in M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Wire
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the unde ...

Cantono Frigerio System
The Cantono Frigerio system was an Italian electric power supply for trackless trolleybuses with two wires about apart being contacted by a four-wheeled collector on a single trolley pole. In English publications it was often described as Filovia system although the Italian language, Italian term ''filovia'' means literally ''wire way'', i.e. a trolleybus line or a trolleybus system. History Werner Siemens introduced the first collector for trackless vehicles with his Electromote cart in 1882, and in 1901 Max Schiemann demonstrated sliding contact shoes, which were pressed by springs against the overhead wires. Five years later ''Eugenio Cantono'' from Rome combined these two principles and exhibited six trolleybuses at the world's fair Milan International (1906), Milan International, 1906. The power supply differed from those in other countries in that, as a collector, a four-wheeled truck ran underneath the wires, held in place by a trolley pole in the usual manner. The poss ...

Electromote
The Electromote was the world's first vehicle run like a trolleybus, which was first presented to the public on April 29, 1882, by its inventor Dr. Ernst Werner von Siemens in Halensee, a suburb of Berlin, Germany. Working on electro-magnetic propulsion In 1847, Siemens told his brother Wilhelm that should he have time and money, he wanted to build himself a carriage with electro-magnetic propulsion. In the early 1880s, he managed to realize the idea, first erecting the masts and infrastructure on site in 1881. Halensee, independent and not yet part of Berlin at the time, had only been named the previous year and was not yet fully developed, providing the project with the space needed as well as access via the Berlin Ringbahn at nearby Halensee station. Operational history The Elektromote operated from April 29 to June 13, 1882, on a trail-track along “Straße No. 5”, today's Joachim-Friedrich-Straße, and “Straße No. 13”, today's Johann-Georg-Straße, crossing the ...

Trolley Pole
A trolley pole is a tapered cylindrical pole of wood or metal, used to transfer electricity from a "live" (electrified) overhead line, 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 Joseph Van Depoele, Charles Van Depoele, in autumn 1885.William D. Middleton, Middleton, William D. (1967). ''The Time of the Trolley'', pp. 63–65, 67. Milwaukee: Kalmbach Publishing. . History An early development of an experimental tramway in Toronto, Ontario, was built in 1883, having been developed by John Joseph Wright (inventor), John Joseph Wright, brother of swindler Whitaker Wright. While Wright may have assisted in the installation of electric railways at the Canadian National Exhibition (CNE), and may even have used a pol ...

Leeds
Leeds is a city in West Yorkshire, England. It is the largest settlement in Yorkshire and the administrative centre of the City of Leeds Metropolitan Borough, which is the second most populous district in the United Kingdom. It is built around the River Aire and is in the eastern foothills of the Pennines. The city was a small manorial borough in the 13th century and a market town in the 16th century. It expanded by becoming a major production and trading centre (mainly with wool) in the 17th and 18th centuries. Leeds developed as a mill town during the Industrial Revolution alongside other surrounding villages and towns in the West Riding of Yorkshire. It was also known for its flax industry, iron foundries, engineering and printing, as well as shopping, with several surviving Victorian era arcades, such as Kirkgate Market. City status was awarded in 1893, and a populous urban centre formed in the following century which absorbed surrounding villages and overtook t ...

Tram
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than Main line (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city stre ...

Battery Electric Bus
A battery electric bus is an electric bus that is driven by an electric motor and obtains energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source. Battery electric buses offer the potential for zero-emissions, in addition to much quieter operation and better acceleration compared to traditional buses. They also eliminate infrastructure needed for a constant grid connection and allow routes to be modified without infrastructure changes, in contrast with a trolleybus. They typically recover braking energy to increase efficiency by a regenerative brake. With energy consumption of about , the cost of ownership is lower than diesel buses.Fraunhofer-Institut für Verkehrs- und Infrastruktursysteme Praxistest mit einem Fahrzeug zwischen 03.11.2014 b ...

Biela Valley Trolleybus
The Biela Valley Trolleybus ( or ''Bielathalbahn'') was a trolleybus service in the Germany, German state of Saxony. The facility opened on 10 July 1901 and had closed again by September 1904. It was one of the first trolleybus operations in the world. The 4.4-kilometre route was also known at the time as the ''Gleislose Bahn'' or "trackless railway" – its full name being ''Gleislose Bielathal-Motorbahn mit elektrischer Oberleitung'' ("Trackless Biela Valley Motor Line with Electric Overhead Cable"). It was operated by the firm of ''Bielathal-Motorbahn Königstein'' and served the lower valley of the Biela (Saxon Switzerland), Biela in Saxon Switzerland. The route linked Königstein (Saxon Switzerland), Königstein on the Elbe with the then-independent village of Königstein (Saxon Switzerland)#Hütten, Hütten. The terminus was at ''Kurbad Königsbrunn''.

Exposition Universelle (1900)
The Exposition Universelle of 1900 (), better known in English as the 1900 Paris Exposition, was a world's fair held in Paris, France, from 14 April to 12 November 1900, to celebrate the achievements of the past century and to accelerate development into the next. It was the sixth of ten major expositions held in the city between 1855 and 1937. It was held at the esplanade of Les Invalides, the Champ de Mars, the Trocadéro and at the banks of the Seine between them, with an additional section in the Bois de Vincennes, and it was visited by more than fifty million people. Many international congresses and other events were held within the framework of the exposition, including the 1900 Summer Olympics. Many technological innovations were displayed at the Fair, including the '' Grande Roue de Paris'' ferris wheel, the '' Rue de l'Avenir'' moving sidewalk, the first ever regular passenger trolleybus line, escalators, diesel engines, electric cars, dry cell batteries, electr ...
