BVG Class E
Class E is a series of ''Großprofil'' (wide profile) multiple units of Berliner Verkehrsbetriebe (BVG) which was exclusively used on East Berlin line E, today line U5 of the Berlin U-Bahn. Except for the two prototypes, all vehicles were built using parts of retired S-Bahn vehicles, namely the bogies and parts of the electrical equipment. History As part of the German reparations after World War II, Berliner Verkehrsbetriebe had to cede 120 vehicles of Class C to Moscow Metro. This type was of particular interest for Moscow as it was the newest class on the Berlin network, and technically very similar to the Moscow class A which had been modelled after it. Hence, a shortage of rolling stock of class E (in the Soviet sector, later East Berlin) was newest wide profile line which had been operated exclusively with Class C stock. To continue services of this route, ''Kleinprofil'' (narrow profile) vehicles of Class AI were transferred from route U2 and had wooden running boards, ...

DRG Class ET 168
The DR Class ET 168 (until 1941: Type "Oranienburg") was the second electric multiple unit that operated on the newly electrified Berlin S-Bahn lines. 17 trainsets in total were ordered by the ''Deutsche Reichsbahn'' in 1925 for delivery into the northern suburbs of Berlin. History Already before the electrified S-Bahn came about, there was a trial for electrified commuter trains running from Potsdamer Wannseebahnhof to Zehlendorf in 1902 and from Potsdamer Ringbahnhof to Lichterfelde Ost from 1903. Also in 1903, the AEG company ran an overhead wire test track from Niederschöneweide to Spindlersfeld. Electrification also came about as part of the solution to increase capacity along the '' Hamburg-Altonaer Stadt- und Vorortbahn''. World War I interrupted the electrification plans from 1914 to 1918, which, however, were revived just afterwards. In 1920 the Prussian state railways ordered six test trains, which were first pulled by steam locomotives until electrification commen ...

Ausbesserungswerk
An Ausbesserungswerk (abbreviation AW or Aw) is a railway facility in German-speaking countries, the primary function of which is the repair (and formerly also the construction) of railway vehicles or their components. It is thus equivalent to a 'repair shop' or 'works'. It is also referred to as a Centralwerkstatt or Zentralwerkstatt (central workshop) or Hauptwerkstatt (main workshop). During the Deutsche Reichsbahn-Gesellschaft (DRG) period between the two world wars these facilities were called Reichsbahnausbesserungswerke (RAW) (Reichsbahn repair shops). Terminology Whilst the term ''Ausbesserungswerk'' was used by the former Deutsche Bundesbahn in West Germany after the war, the railway workshops in the Deutsche Reichsbahn in East Germany continued to refer to them as ''Reichsbahnausbesserungswerke'' until 1992. The term ''Hauptwerkstatt'' was also commonly used by state railways ('' Länderbahn'') or private railways and they are still called that today, for example, in Au ...

Multiple-unit Train Control
Multiple-unit train control, sometimes abbreviated to multiple-unit or MU, is a method of simultaneously controlling all the traction equipment in a train from a single location—whether it is a multiple unit comprising a number of self-powered passenger cars or a set of locomotives—with only a control signal transmitted to each unit. This contrasts with arrangements where electric motors in different units are connected directly to the power supply switched by a single control mechanism, thus requiring the full traction power to be transmitted through the train. A set of vehicles under multiple unit control is referred to as a consist in the United States. Origins Multiple unit train control was first used in electric multiple units in the 1890s. The Liverpool Overhead Railway The Liverpool Overhead Railway opened in 1893 with two-car electric multiple units, controllers in cabs at both ends directly controlling the traction current to motors on both cars.

Scharfenberg Coupler
The Scharfenberg coupler (german: Scharfenbergkupplung, abbreviated ''Schaku'') is a commonly used type of fully automatic railway coupling. Designed in 1903 by Karl Scharfenberg in Königsberg, Germany (today Kaliningrad, Russia), the coupler has gradually spread from transit trains to regular passenger service trains, although outside Europe its use is generally restricted to mass transit systems. The ''Schaku'' is superior in many ways to the AAR (Janney/knuckle) coupler because it also automates electrical and pneumatic connections and disconnections. However, there is no standard for the placement of these electro-pneumatic connections. Some rail operators have placed them on the sides while others have placed them either below or above the mechanical portion of the coupler. . Working principles The face of the Scharfenberg coupler has a protruding cone and a matching cup. Inside the cone there is a rigid metal hoop connected to a revolving, spring-loaded metal disk with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. Th ...

Dynamic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical ...

LEW Hennigsdorf
The rail vehicle factory in Hennigsdorf, Germany, was founded in 1910 by AEG. Locomotive production began in 1913, and in the 1930s absorbed the work of the August Borsig locomotive factory, being renamed the Borsig Lokomotiv Werke GmbH until 1944. After the Second World War the factory was nationalised in the German Democratic Republic and produced electric locomotives for home use and for export, mainly to Communist Bloc countries under the name Lokomotivbau-Elektrotechnische Werke (LEW). After German reunification in 1990, the plant returned to AEG ownership, becoming AEG Schienenfahrzeuge GmbH, and then passed through mergers of its parent companies to Adtranz (1996), Bombardier Transportation (2001) and then Alstom (2021). Under Adtranz's ownership production of locomotives ended, and the site now manufactures diesel and electric multiple units. History In 1910 the AEG company acquired a of land in Hennigsdorf near Berlin for the creation of a ceramics factory which began ...

After World War II the trains of the Berlin U-Bahn were worn out, making a new series of trains necessary. From 1957 on the new ''D'' type trains were delivered (also called Stahldora/Steel Dora). They were made of steel, making them very heavy. In 1965, the ''DL'' type was developed, which was constructed from lighter metals (also called Dora). This way, weight was reduced by 26%. Like in earlier types the seats were located along the sides of the train. Class D The D type cars have been introduced in various phases: *D 55: The test vehicle (2000/2001), which is on the Line C II (Mehringdamm - Tempelhof) *D 57: 26 trains (2002/2003 - 2052/2053), whic ...
