Deutsche Bundesbahn
The Deutsche Bundesbahn or DB (German Federal Railway) was formed as the state railway of the newly established Federal Republic of Germany (FRG) on 7 September 1949 as a successor of the Deutsche Reichsbahn-Gesellschaft (DRG). The DB remained the state railway of West Germany until after German reunification, when it was merged with the former East German Deutsche Reichsbahn (DR) to form Deutsche Bahn, which came into existence on 1 January 1994. Background After World War II, each of the military governments of the Allied Occupation Zones in Germany were ''de facto'' in charge of the German railways in their respective territories. On 10 October 1946, the railways in the British and American occupation zones formed the ''Deutsche Reichsbahn im Vereinigten Wirtschaftsgebiet'' (German Imperial Railway in the united economic area), while on 25 June 1947, the provinces under French occupation formed the Südwestdeutsche Eisenbahn. With the formation of the FRG these succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hamburg S-Bahn
The Hamburg S-Bahn is a suburban commuter railway network in the Hamburg Metropolitan Region. Together, the S-Bahn, the Hamburg U-Bahn, the AKN railway and the regional railway form the backbone of railway public transport in the city and the surrounding area. The network has operated since 1907 as a commuter rail system, under the direction of the state railway, and is a member of the Hamburger Verkehrsverbund (HVV; Hamburg Transport Association). There are six lines, serving 68 stations, on of route. On an average working day the S-Bahn transports about 590,000 passengers; in 2010 about 221 million people used the S-Bahn. The S-Bahn is the only railway in Germany that uses both 1,200 V DC supplied by a third rail and supplied by overhead lines. Most of the tracks are separated from other rail services. The S-Bahn is operated by S-Bahn Hamburg GmbH, a subsidiary of DB Regio. Similarly to Berlin but unlike Hanover, the S-Bahn is an important part of public transport within ...

Messerschmitt-Bölkow-Blohm
Messerschmitt-Bölkow-Blohm (MBB) was a West German aerospace manufacturer. It was formed during the late 1960s as the result of efforts to consolidate the West German aerospace industry; aircraft manufacturer Messerschmitt AG merged with the civil engineering and aviation firm Bölkow during 1968, while rival aircraft manufacturer Hamburger Flugzeugbau was acquired by the company in the following year. The company was responsible for the development and manufacture of various aircraft during its existence. Among its best-known products was the MBB Bo 105 light twin-engine helicopter and its enlarged derivative, the MBB/Kawasaki BK 117. MBB was also a key early partner on the Airbus A300, a wide-body twin-jet airliner; the company's involvement in the A300's development and production led to it forming a key component of the multinational Airbus consortium. It was also involved in numerous experimental aircraft programmes, such as the MBB Lampyridae, an aborted stealth aircraft. ...

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] |
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 ...

Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are usually supplied from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...

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 ...

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 ...
