HHA Type DT1
The Type DT1 is a two-car electric multiple unit (EMU) train type operated by the Hamburger Hochbahn AG on the Hamburg U-Bahn until 1991. They were the first new U-Bahn trains since the 1920s. Technical specifications The trains were formed as two-car sets. The car bodies are made out of welded steel. Each bogie is fitted with two axle-hung motors. Interior The first sets were fitted with longitudinal seating. Subsequent sets were fitted with a mix of longitudinal and transverse seats. File:DT1 Hamburg Innenraum.JPG, Interior of the DT1 heritage train History The trains were originally numbered 9431/9432 to 9529/9530, and were renumbered to 9000/9001 to 9098/9099 in 1960. Their livery was changed in 1969 to unify the look of the Hochbahn trains, with the DT1 trains receiving a grey livery with red doors and cab ends, similar to the Type DT2 and Type DT3. DT1 trains were restricted to peak-hour services since 1971. The sets still in service in the 1980s were renumbered to ... [...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 ...

Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Bar (establishment)
A bar, also known as a saloon, a tavern or tippling house, or sometimes as a pub or club, is a retail business establishment that serves alcoholic beverages, such as beer, wine, liquor, cocktails, and other beverages such as mineral water and soft drinks. Bars often also sell snack foods, such as crisps or peanuts, for consumption on their premises. Some types of bars, such as pubs, may also serve food from a restaurant menu. The term "bar" refers to the countertop where drinks are prepared and served, and by extension to the overall premises. The term derives from the metal or wooden bar (barrier) that is often located along the length of the "bar". Over many years, heights of bars were lowered, and high stools added, and the brass bar remains today. Bars provide stools or chairs that are placed at tables or counters for their patrons. Bars that offer entertainment or live music are often referred to as "music bars", "live venues", or "nightclubs". Types of bars ra ...

Passenger Train Toilet
Many passenger trains (usually medium and long-distance) have toilet facilities, often at the ends of carriages. Toilets suitable for wheelchair users are larger, and hence trains with such facilities may not have toilets in each carriage. Hopper toilet The traditional method of disposing human waste from trains is to deposit the waste onto the tracks or, more often, onto nearby ground using what is known as a hopper toilet. This ranges from a hole in the floor to a full-flush system (possibly with sterilization). The hole in the floor (also known as a drop chute toilet or direct flush toilet) system is still in use in many parts of the world, particularly on older rolling stock. The principal disadvantage is that it can be considered crude or unhygienic and dangerous to health and the environment – it litters the railway lines and can convey serious health risks when the train passes over or under a navigable waterway. Passengers may be discouraged from flushing or using toil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
