DB Class 420
The Class 420 (german: Baureihe 420) is a commuter electric multiple unit train type in service on German S-Bahn networks since 1972. Their use in Munich during the 1972 Summer Olympics earned them the colloquial name (Olympic multiple unit). Design Livery variations Each of the three prototype sets received a different livery. 420 001 had an orange and white livery, 420 002 had a blue and white livery, and 420 003 wine-red and white livery. A public poll over the livery of the S-Bahn trains was held in Frankfurt, Munich and Düsseldorf. Munich received blue trains, Düsseldorf chose orange and Frankfurt also received orange liveried trains due to economic reasons, despite opting for the red livery. Units used on Munich S-Bahn services to the airport received a light blue livery. All units still in service were repainted into the traffic-red livery.

Wiesbaden Ost Station
Wiesbaden Ost (east) station is situated on the Frankfurt–Wiesbaden line (line number 3603; timetable section 645.1) in the German state of Hesse. It was opened as part of the Taunus Railway, which was opened in 1839/40. The station was opened as part of the last stage of construction of the line to Wiesbaden and was opened on 19 May 1840. History Originally the station was called "Biebrich Curve" and it was later called "Biebrich Ost". After the incorporation of Biebrich into Wiesbaden, "Wiesbaden" was added to its name in 1927, but "Biebrich" was deleted in 1934 and only "Ost" was maintained in the station name. This led to a geographically incorrect name as the station is located in the south of Wiesbaden. On 3 August 1840, a 1.5 kilometre spur line was opened that branched off from here to the Biebrich Rhine station in Biebrich to connect the Taunus Railway with the free port on the Rhine. The ''Sackbahnhof'' (sack station) on the Rhine shore was in the immediate vic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Commutator (electric)
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine. Two or more electrical contacts called "brushes" made of a soft conductive material like carbon press against the commutator, making sliding contact with successive segments of the commutator as it rotates. The windings (coils of wire) on the armature are connected to the commutator segments. Commutators are used in direct current (DC) machines: dynamos (DC generators) and many DC motors as well as universal motors. In a motor the commutator applies electric current to the windings. By reversing the current direction in the rotating windings each half turn, a steady rotating force (torque) is produced. In a generator the commutator picks off the current generated in ...

Phase-fired Controller
Phase-fired control (PFC), also called phase cutting or "phase angle control", is a method for power limiting, applied to AC voltages. It works by modulating a thyristor, SCR, triac, thyratron, or other such gated diode-like devices into and out of conduction at a predetermined phase of the applied waveform. Overview Phase-fired control (PFC) is often used to control the amount of voltage, current or power that a power supply feeds to its load. It does this to create an average value at its output. If the supply has a DC output, its time base is of no importance in deciding when to pulse the supply on or off, as the value that will be pulsed on and off is continuous. PFC differs from Pulse-width modulation (PWM) in that it addresses supplies that output a modulated waveform, such as the sinusoidal AC waveform that the national grid outputs. Here, it becomes important for the supply to pulse on and off at the correct position in the modulation cycle for a known value to b ...

Brown-Boveri
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network.

1972 Summer Olympics
The 1972 Summer Olympics (), officially known as the Games of the XX Olympiad () and commonly known as Munich 1972 (german: München 1972), was an international multi-sport event held in Munich, West Germany, from 26 August to 11 September 1972. The event was overshadowed by the Munich massacre in the second week, in which eleven Israeli athletes and coaches and a West German police officer at Olympic village were killed by Palestinian Black September members. The motivation for the attack was the ongoing Palestinian-Israeli conflict. The 1972 Summer Olympics were the second Summer Olympics to be held in Germany, after the 1936 Games in Berlin, which had taken place under the Nazi regime, and the most recent Olympics to be held in the country. The West German Government had been eager to have the Munich Olympics present a democratic and optimistic Germany to the world, as shown by the Games' official motto, ''"Die Heiteren Spiele"'', or "the cheerful Games".

S-Bahn
The S-Bahn is the name of hybrid urban-suburban rail systems serving a metropolitan region in German-speaking countries. Some of the larger S-Bahn systems provide service similar to rapid transit systems, while smaller ones often resemble commuter or even regional rail. The term derives from ''Schnellbahn'', ''Stadtbahn'' or ''Stadtschnellbahn''. Similar systems in Switzerland are known as S-Bahn as well. In Belgium it is known as S-Trein (Flemish) or Train S (French). In Belgium there are S-Trains in the five largest cities: Brussels, Antwerp, Liège, Ghent and Charleroi. In Denmark, they are known as S-tog , in the Czech Republic as Esko or S-lines. Characteristics There is no complete definition of an S-Bahn system. S-Bahn are, where they exist, the most local type of railway stopping at all existing stations inside and around a city, while other mainline trains only call at major stations. They are slower than mainline railways but usually serve as fast crosstown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
