Hamburg U-Bahn Type DT2
The Type DT2 is a two-car electric multiple unit (EMU) train type operated by the Hamburger Hochbahn AG on the Hamburg U-Bahn until 2015. They replaced the Type T and Type TU. Technical specifications The first trains had a ''Bo'1+1 Bo axle layout, with later trains built to an articulated design, formed as two-car sets. Up to four sets can be coupled together to form a long train. The car body was constructed using lightweight steel, based on a design licensed from the American Budd Company. They are equipped with Kiepe-build quill drives. Interior Seating arrangement consists of seating bays in a 2+2 layout.

Linke-Hofmann-Busch
Alstom Transport Deutschland, formerly Linke-Hofmann-Busch, is a German manufacturing company originally established in Breslau (now Wrocław, Poland) to produce locomotives and rolling stock. Its origins lay in the wheelwright business of Gottfried Linke, begun in 1834. After World War II, the company was reestablished in Salzgitter in West Germany. In 1994, GEC Alsthom acquired a 51% shareholding.World Update ''Railway Age'', August 1994, p. 88. It is now part of Alstom; the name Linke-Hofmann-Busch ceased to be used in 2009 when it became Alstom Transport Deutschland GmbH. Aircraft industry During World War I, it became one of many companies in Germany drawn into the aircraft industry even though they had no prior experience in aircraft design. Linke-Hofmann-Busch first entered the aircraft industry by repairing and constructing aircraft designed by other established companies under licence, such as the Roland C.IIa, Albatros B.IIa, C.III and C.X. In 1916 Linke-Hofmann-B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiepe
Kiepe Electric GmbH (formerly Vossloh Kiepe) is a German manufacturer of electrical traction equipment for trams, trolleybuses other road and rail transport vehicles, as well as air-conditioning and heating systems, and conveyor device components. Founded in 1906, it was known as Kiepe Elektrik GmbH until 2003, when it was renamed Vossloh Kiepe, following its acquisition by Vossloh AG. Vossloh sold the company to Knorr-Bremse in January 2017, and in May 2017 Knorr renamed it Kiepe Electric GmbH. History In 1906, Theodor Kiepe created an electric arc lamp repair workshop in Düsseldorf. Over the next 40 years the company's product range grew to include electrical switches, then electrical drum controllers and resistors for electric vehicles. By 1951, the product range included electro-pneumatic contactors, and traction motors; in 1952, the company supplied equipment for an order of 700 trolleybuses for Argentina. Between the 1950s and 1970s Kiepe Elektrik GmbH expanded, with form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamburger Hochbahn AG
Hamburger Hochbahn AG (HHA), founded in 1911, operates the underground system and large parts of the bus system in Hamburg, Germany. History The HHA was founded by Siemens & Halske and AEG as a consortium on 27 May 1911. The first chairman was Albert Ballin. From 1919 until 1978, the HHA operated a large tram network, and from 5 December 1921 the HHA also operated the first motor buses in Hamburg. After the acquisition of the ''Straßen-Eisenbahn-Gesellschaft'' (SEG) in 1919 and the ''Hamburg-Altonaer-Centralbahngesellschaft AG'' in 1923, the HHA had a rolling stock of 865 power cars and 930 trailers by 1928. The length of tracks was 217.33 km. In 1970 the length of the lines were only 82.7 km, in 1978 they were 89.5 km with 80 stations. In 1965, HHA was one of the founding members of the Hamburger Verkehrsverbund (HVV). Operations HHA operates about 111 bus routes and four underground lines. In spite of the "U" for "underground", large portions, especial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Contact Shoe
Electric current collectors are used by trolleybuses, trams, electric locomotives or EMUs to carry electrical power from overhead lines, electrical third rails, or ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies. Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor. The current collector arms are electrically conductive but mounted insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or motor. The steel rails of the tracks act as the electrical return. Electric vehicles that collect their current from an overhead line system use different forms of one- or two-arm pantograph ...

Sifa
Sifa is a type of deadman's control system used on German-influenced European railways.{{cite web , url = http://www.virtualmarket.innotrans.de/index.php5?id=1022238&highlight=&fid=523&offset=0&Action=showProduct , title = Deadman's control system UDB , accessdate=2008-12-24 Although deadman's pedals are commonly used on railways worldwide, Sifa systems are specifically those codified by German Industrial Norms VDE 0119-207-5. In Switzerland the equivalent system is called 'safety control' (''Sicherheitssteuerung'').Eidgenössisches Departement für Umwelt, Verkehr, Energie und Kommunikation''Ausführungsbestimmungen zur Eisenbahnverordnung (AB-EBV)', as at: 01July 2016 Description Sifa is short for ''Sicherheitsfahrschaltung'', German for "safety driving circuit". It is usually a pedal and/or large press button, which monitors the alertness of the driver. The driver has to repeatedly press a button after a fixed interval; if they fail to do so, the train will carry out an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

Hamburg U-Bahn
The Hamburg U-Bahn is a rapid transit system serving the cities of Hamburg, Norderstedt and Ahrensburg in Germany. Although referred to by the term U-Bahn (the "U" commonly being understood as standing for "underground"), most of the system's track length is above ground. The network is interconnected with the city's S-Bahn system, which also has underground sections. It is operated by Hamburger Hochbahn within the Hamburger Verkehrsverbund (HVV). It was opened in February 1912, and comprises four lines serving 93 stations, with a route length of in 2019. History In 1906 the Senate of Hamburg awarded a contract for the Elevated and Underground Railway to Siemens & Halske and AEG of Berlin. The first stretch was completed on 7 October 1906. This was followed in 1911 with the founding of the ''Hamburger Hochbahn Aktiengesellschaft'' (HHA). Thus Hamburg became the third German city (after Berlin, 1902 and Schöneberg, 1910) to have a U-Bahn (then known as the Elevated and Un ...

Hamburg U-Bahn Type A
The Type A is an electric multiple unit (EMU) train type formerly operated on the Hamburg U-Bahn system. They were the first type of subway cars in Hamburg, entering service on 15 February 1912, and were later designated as Type T. Some cars were converted to maintenance service cars. Variants Type A and Type T Type A cars, later designated as Type T, had wooden car bodies and two manually operated sliding doors per side. Seating accommodation consisted of a mix of longitudinal and transverse seats. Some cars were equipped with two cabs. The last Type T car was withdrawn in 1970.

Articulated Car
Articulated cars are rail vehicles which consist of a number of cars which are semi-permanently attached to each other and share common Jacobs bogies or axles and/or have car elements without axles suspended by the neighbouring car elements. They are much longer than single passenger cars. Because of the difficulty and cost of separating each car from the next, they are operated as a single unit, often called a ''trainset''. Passenger cars Articulated passenger cars are becoming increasingly common in Europe and the US. The passageways between the car elements are permanently attached. There is a safety benefit claimed that if the train derails, it is less likely to jackknife and modern construction techniques prevent telescoping. Articulated cars are not, however, a new idea. Many railways in Britain during the first half of the 20th century frequently rebuilt older, shorter cars into articulated sets, and the Great Northern Railway in Britain built suburban car sets n ...

Budd Company
The Budd Company was a 20th-century metal fabricator, a major supplier of body components to the automobile industry, and a manufacturer of stainless steel passenger rail cars, airframes, missile and space vehicles, and various defense products. Budd was founded in 1912 in Philadelphia by Edward G. Budd, whose fame came from his development of the first all-steel automobile bodies in 1913, and his company's invention of the " shotweld" technique for joining pieces of stainless steel without damaging its anti-corrosion properties in the 1930s. Budd Company became part of Budd Thyssen in 1978, and in 1999 a part of ThyssenKrupp Budd. Body and chassis operations were sold to Martinrea International in 2006. No longer an operating company, Budd filed for bankruptcy in 2014. It currently exists to provide benefits to its retirees. Automobiles Edward G Budd developed the first all-steel automobile bodies. His first major supporters were the Dodge brothers. Following discussions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quill Drive
A quill is a writing tool made from a moulted flight feather (preferably a primary wing-feather) of a large bird. Quills were used for writing with ink before the invention of the dip pen, the metal-Nib (pen), nibbed pen, the fountain pen, and, eventually, the ballpoint pen. As with the earlier reed pen (and later dip pen), a quill has no internal ink reservoir and therefore needs to periodically be dipped into an inkwell during writing. The hand-cut goose quill is rarely used as a Western calligraphy, calligraphy tool anymore because many papers are now derived from Pulp (paper), wood pulp and would quickly wear a quill down. However, it is still the tool of choice for a few scribes who have noted that quills provide an unmatched sharp stroke as well as greater flexibility than a steel pen. Description The shaft of a flight feather is long and hollow, making it an obvious candidate for being crafted into a pen. The process of making a quill from a feather involves Curing (che ...
