Kriegslokomotiven
''Kriegslokomotiven'' (german: for "war locomotives", singular: ''Kriegslokomotive'') or ''Kriegsloks'' were locomotives produced in large numbers during the Second World War under Nazi Germany. Their construction was tailored to the economic circumstances of wartime Germany along with conquered and occupied territories across Europe, taking account of the shortage of materials, the transportation of goods in support of military logistics, ease of maintenance under difficult conditions, resistance to extreme weather, limited life and the need for rapid, cheap mass production. In order to meet these requirements, economic drawbacks such as relatively high fuel consumption had to be accepted. Forced labour was used in the construction of some of the locomotives; German locomotive building firms employed prisoners from concentration camps and foreign, mostly Polish, workers. Construction The war locomotives (or ''Kriegslokomotiven'') were kept technically as simple as possible and ...

Virtual Shtetl
The Virtual Shtetl ( pl, Wirtualny Sztetl) is a bilingual Polish-English portal of the Museum of the History of Polish Jews in Warsaw, devoted to the Jewish history of Poland. History The Virtual Shtetl website was officially launched on June 16, 2009 by founder Albert Stankowski. The portal lists over 1,900 towns with maps, statistics and picture galleries. In the future, it will also include an interactive system by which Internet users will interact with each other. It creates a link between Polish-Jewish history and the contemporary, multi-cultural world. The Virtual Shtetl is an extension of the real Museum scheduled to open in 2011 on the site of the Warsaw ghetto. Its main objective is to provide a unique social forum for everyone interested in Polish-Jewish life. The "Virtual Shtetl" re-tells the history of Polish Jews which existed, to a great extent, in a town or a village (Yiddish: shtetl). But besides that, it also provides information about German Jews and the Jew ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential transfo ...

Traction Motors
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles ( electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control Direct-current motors with series field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively smooth operator control of acceleration. A further measure of contro ...

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ...
