Stadtbahnwagen B
The Stadtbahnwagen Typ B (translation ''Type "B" Light Rail Vehicle'', short form B-Wagen) is a light rail vehicle used by several Stadtbahn networks in the German state of North Rhine-Westphalia. It was mainly developed by Düsseldorf-based Duewag, who also built the majority of vehicles in a consortium with Siemens and Kiepe. A small series of ten units was built by Waggon Union in Berlin. As the type evolved over two decades of production, some vehicles have little more in common than their outer dimensions and the basic configuration of a two-part multiple unit on three bogies with both outer ones powered. For the Dortmund Stadtbahn, some cars were modified with a central section and a fourth bogie. These vehicles are referred to as ''B8'' or '' B80C/8'' (eight axles). These vehicles have a length of and a weight of . History When the Rhine-Ruhr Stadtbahn network was planned in the early 1970s, standardised rolling stock was planned as well. At the same time, a second Stadt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duewag
Düwag or Duewag, formerly Waggonfabrik Uerdingen, was a German manufacturer of rail vehicles. It was sold in 1999 to Siemens with the brand later retired. History Duewag was founded in March 1898 as Waggonfabrik Uerdingen in Uerdingen and produced rail vehicles under the Düwag brand. After merging with Düsseldorfer Waggonfabrik in 1935, railway vehicles were built in Uerdingen, while the Düsseldorf plant produced mainly local traffic vehicles, namely tramway and light rail vehicles. In 1981, the company changed its name from Waggonfabrik Uerdingen to Duewag. Siemens acquired a 60% shareholding in 1989 before taking full ownership in April 1999. In 2001, the Düsseldorf plant was closed with production transferred to Uerdingen. Duewag vehicles were close to a monopoly market in West Germany, as nearly every tram and light rail vehicle purchased from the 1960s onward was built by Duewag.

Cologne Stadtbahn
The Cologne Stadtbahn is a light rail system in the German city of Cologne, including several surrounding cities of the Cologne Bonn Region (Bergisch Gladbach, Bonn, Bornheim, Brühl, Frechen, Hürth, Leverkusen-Schlebusch, Wesseling). The term ''Stadtbahn'' denotes a system that encompasses elements of trams as well as an underground railway network (''U-Bahn'') and interurban rail, even including three lines that are licensed as heavy rail and used by freight trains as well as Stadtbahn vehicles. Two of these lines connect the Cologne Stadtbahn to the Bonn Stadtbahn. These lines (16 and 18) are jointly operated by both cities' transport authorities, resulting in both systems and the lines connecting them sometimes collectively referred to as ''Stadtbahn Rhein-Sieg''. The Cologne Stadtbahn is operated by the Kölner Verkehrsbetriebe (KVB) and the Bonn Stadtbahn is operated by the Stadtwerke Bonn (SWB – City of Bonn Utilities Division). The KVB and SWB are members of the V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tram Vehicles Of Germany
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 United ...

Chopper (electronics)
In electronics, a chopper circuit is any of numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to interrupt one signal under the control of another. In power electronics applications, since the switching element is either fully on or fully off, its losses are low and the circuit can provide high efficiency. However, the current supplied to the load is discontinuous and may require smoothing or a high switching frequency to avoid undesirable effects. In signal processing circuits, use of a chopper stabilizes a system against drift of electronic components; the original signal can be recovered after amplification or other processing by a synchronous demodulator that essentially un-does the "chopping" process.

Contactor
:''In semiconductor testing, contactors can also be referred to as the specialized socket that connects the device under test.'' :''In process industries, a contactor is a vessel where two streams interact, for example, air and liquid. See Gas-liquid contactor.'' A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. Unlike general-purpose relays, contactors are designed to be directly connected to high-current load devices. Relays tend to be of lower capacity and are usually designed for both ''normally closed'' and ''normally open'' applications. Devices switching more than 15 amperes or in circuits rated more than a few kilowatts are usually called contactors. Apart from optional auxiliary low-current contacts, contactors are almost exclusively fitted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyne And Wear Metro
The Tyne and Wear Metro is an overground and underground light rail rapid transit system serving Newcastle upon Tyne, Gateshead, North Tyneside, South Tyneside, and the City of Sunderland (together forming Tyne and Wear). The network opened in stages from August 1980 and now serves a total of 60 stations, with two lines covering of track. The Metro can be accessed from a mixture of under ground and above ground stations. It has been described as the "first modern light rail system in the United Kingdom". The system is currently owned and operated by the Tyne and Wear Passenger Transport Executive (branded as Nexus), thus is fully under public ownership and operation. In 2018–19, an estimated 36.4million passenger journeys were made on the Metro, making it the third-most used light rail network in the United Kingdom after London's Docklands Light Railway (121.8million passenger journeys) and Manchester Metrolink (43.7million passenger journeys).

Tyne And Wear Metrocar
The Tyne and Wear Metrocars are a fleet of light rail vehicles manufactured by Metro-Cammell for the Tyne and Wear Metro in North East England between 1978 and 1981. For operation on Network Rail controlled tracks between Pelaw Junction and Sunderland, they are designated on TOPS as the Class 599. Most were refurbished between 2010 and 2015 by Wabtec Rail at Doncaster Works and are scheduled to be replaced by Class 555 rolling stock from 2023. Design The design of the Metrocars was partly derived from that of the German Stadtbahnwagen B. However, they were built by Metro-Cammell in Birmingham, and were not fitted with the lights and indicators that would have allowed them to run on streets. Each Metrocar consists of two semi-permanently connected coaches mounted on three bogies, with the middle bogie being a Jacobs Bogie. The outermost bogies are powered and the centre Jacobs Bogie, located in the articulated section between both halves is unpowered. The trains make use o ...

Mülheim
Mülheim, officially Mülheim an der Ruhr () and also described as ''"City on the River"'', is a city in North Rhine-Westphalia in Germany. It is located in the Ruhr Area between Duisburg, Essen, Oberhausen and Ratingen. It is home to many companies, especially in the food industry, such as the Aldi Süd Company, the Harke Group and the Tengelmann Group.
