Tatra T5B6
The Tatra T5B6 was an experimental tramcar built in 1976 by ČKD Tatra. History Having enjoyed widespread success throughout the Soviet Union with its earlier products, Tatra were keen to develop a new, modernised generation of tramcars for its clients. After initial runs on test-track at the Tatra factory, two prototypes were delivered to Most for evaluation, where they spent a year. The transport authorities in Most were however unwilling to pay a higher price for the T5B6 than they would otherwise have paid for the T3SU and no more orders were placed. The original prototype is still in Most, however it does not see active service and is kept only as an historic History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well ... vehicle.

ČKD
ČKD (Českomoravská Kolben-Daněk) () was one of the largest engineering companies in the former Czechoslovakia and today's Czech Republic. It is famous for the Tatra T3, a tramcar that sold 13,991 units worldwide. History ČKD was formed in 1927 from the merger of two smaller companies, Českomoravská-Kolben (founded 1896, produced machinery for hydro dams) and Breitfeld-Daněk (founded 1854, produced machinery for mines and food industry). From 1927 until 1929 ČKD's products included a motorcycle designed by Jaroslav František Koch. It was an advanced four-stroke single-cylinder unit construction double overhead camshaft design of 500cc. It was sold under the marque BD, thus perpetuating the Breitfeld-Daněk identity. In 1929 ČKD sold its motorcycle business to Praga Hostivař, which re-branded the motorcycles under the Praga marque. It was one of the main suppliers to the Czechoslovak state of military vehicles during the 1930s. During the German occupation of Cz ...

Pantograph (transport)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and paten ...

Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) 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 Unit ...

Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''prototype'' derives from the Greek , "primitive form", neutral of , "original, primitive", from πρῶτ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Historic
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
