Republished 2004 with or 9780753709702.) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) 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 (or pantograph). 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. Currently, around 300 trolleybus systems are in operation, in cities and towns in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernst Werner Von Siemens
Ernst Werner Siemens (von Siemens from 1888; ; ; 13 December 1816 – 6 December 1892) was a German electrical engineer, inventor and industrialist. Siemens's name has been adopted as the SI unit of electrical conductance, the siemens. He founded the electrical and telecommunications conglomerate Siemens. Biography Early years Ernst Werner Siemens was born in Lenthe, today part of Gehrden, near Hannover, in the Kingdom of Hanover in the German Confederation, the fourth child (of fourteen) of a tenant farmer of the Siemens family, an old family of Goslar, documented since 1384. He was a brother of Carl Heinrich von Siemens and Carl Wilhelm Siemens, sons of Christian Ferdinand Siemens (31 July 1787 – 16 January 1840) and wife Eleonore Deichmann (1792 – 8 July 1839). Middle years After finishing school, Siemens intended to study at the Bauakademie Berlin. However, since his family was highly indebted and thus could not afford to pay the tuition fees, he chose to join the Pru ...

Leeds
Leeds () is a city and the administrative centre of the City of Leeds district in West Yorkshire, England. It is built around the River Aire and is in the eastern foothills of the Pennines.

Reading Trolleybus At Three Tuns
Reading is the process of taking in the sense or meaning of Letter (alphabet), letters, symbols, etc., especially by Visual perception, sight or Somatosensory system, touch. For educators and researchers, reading is a multifaceted process involving such areas as word recognition, orthography (spelling), Alphabetic principle, alphabetics, phonics, phonemic awareness, vocabulary, comprehension, fluency, and motivation. Other types of reading and writing, such as pictograms (e.g., a hazard symbol and an emoji), are not based on speech-based writing systems. The common link is the interpretation of symbols to extract the meaning from the visual notations or tactile signals (as in the case of Braille). Overview Reading is typically an individual activity, done silently, although on occasion a person reads out loud for other listeners; or reads aloud for one's own use, for better comprehension. Before the reintroduction of Palaeography, separated text (spaces between words) in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantono Frigerio System
The Cantono Frigerio system was an Italian electric power supply for trackless trolleybuses with two wires about 20 inches (50 cm) 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 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. 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 possible deviation on either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biela Valley Trolleybus
The Biela Valley Trolleybus (german: Bielatalbahn or ''Bielathalbahn'') was a trolleybus service in the 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 in Saxon Switzerland. The route linked Königstein on the Elbe with the then-independent village of Hütten. The terminus was at ''Kurbad Königsbrunn''. [Baidu] |
