Wismar Railbus
The 'Hanover version' of the Wismar railbus (''Wismarer Schienenbus'') was developed in the early 1930s as a light railbus for economical passenger services on branch lines in Germany. History As early as the 1920s, light branch lines (the so-called ''Kleinbahnen'') were looking for ways to operate lightly used routes as cheaply as possible. The overwhelmingly employed mixed trains were very slow because of the time needed for shunting wagons. In addition, only a few trains ran each day. In order to offer faster and more frequent services, railbuses were procured. Because they tended to be one-offs and the technology was not always fully mature, they were often expensive. So attempts were made to use the experience and components from the manufacture of buses. Experiments with converted buses were not successful as their engines were not powerful enough and, moreover, they were not designed for push-pull operations. In 1932 the Triebwagen- und Waggonfabrik Wismar AG (Wismar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DGEG
The German Railway History Company (''Deutsche Gesellschaft für Eisenbahngeschichte'') or DGEG is a society concerned with the history of the railways. The objectives of the society are: * to generate and maintain interest and understanding for the history of the railways within the framework of overall history, * to foster scientific studies in this area, * to preserve and maintain important cultural and technological monuments. History The society was founded on 22 April 1967 in Karlsruhe and was entered on the official register of clubs and societies there. Members of the society were able to gradually restore the Bochum-Dahlhausen locomotive shed and its surroundings to their former condition after their closure by the Deutsche Bundesbahn on 1 August 1969. Because the arrival of railway vehicles was imminent in 1972 and Dahlhausen was still not totally ready, the locomotive shed next to the workshop building of the old Neustadt/Haardt locomotive shed was rented. In 1981 then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A ''loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunting Oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system "hunts" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering. Railway wheelsets A classical hunting oscillation is a swaying motion of a railway vehicle (often called ''truck hunting'' or ''bogie hunting'') caused by the coning action on which the directional stability of an adhesion railway depends. It arises from the interaction of adhesion forces and inertial forces. At low speed, adhesion dominates but, as the speed increases, the adhesion forces and inertial forces become comparable in magnitude and the oscillation begins at a critical speed. Above this speed, the motion can be violent, damaging track and wheels and potentially causing derailment. The problem does not occur on systems with a differential because the action dep ...

Intercity-Express
The Intercity Express (commonly known as ICE ()) is a system of high-speed trains predominantly running in Germany. It also serves some destinations in Austria, Denmark (ceased in 2017 but planned to resume in 2022), France, Belgium, Switzerland and the Netherlands, mostly as part of cross border services. It is the highest service category of rail and the flagship train of the German state railway, Deutsche Bahn. There are currently 315 trainsets in use. ICE trains are the highest category (Class A) trains in the fare system of the Deutsche Bahn. Their fares are not calculated on a fixed per-kilometre table as with other trains, but instead have fixed prices for station-to-station connections, levied on the grounds that the ICE trains have a higher level of comfort. Travelling at speeds up to , they are tailored for business travellers or long-distance commuters and are marketed by Deutsche Bahn as an alternative to flights. Apart from domestic use, the trains can also be see ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robur (truck)
Robur was a marque of the Volkseigener Betrieb ''VEB Robur-Werke Zittau'' of East Germany (GDR). It mainly produced 3-ton trucks. The vehicles were produced in the town of Zittau in what now is South-East Saxony. Until 1946, company produced under the marque ''Phänomen'' (English: Phenomenon), and until 1957 under the name ''VEB Phänomen Zittau''. History In 1888, Karl Gustav Hiller founded a company for the distribution of a pom-pon machine that he had invented and would receive a patent for in 1894. On a trip to England he obtained an exclusive license to import and build Rover Safety Bicycles. He became shareholder and later owner of the Zittau machine factory "Müller & Preußger", refined the Rover bicycles and began to distribute them under the name "Phänomen-Rover" in 1894. In 1900 the company began to produce Phänomen motorcycles. At first the motorcycles were fitted with Fafnir engines, but from 1903 onwards single-cylinder four-stroke engines of Phäno ...

East German Deutsche Reichsbahn
The Deutsche Reichsbahn or DR ''(German Reich Railways)'' was the operating name of state owned railways in the German Democratic Republic (East Germany), and after German reunification until 1 January 1994. In 1949, occupied Germany's railways were returned to German control after four years of Allied control following World War II. Those in the Soviet occupation zone (which became the German Democratic Republic or GDR on 7 October 1949) continued to run as the Deutsche Reichsbahn, the name given to the German national railways in 1937. In West Germany, the Reichsbahn was succeeded by the Deutsche Bundesbahn (DB). Both the Reichsbahn and the Bundesbahn continued as separate entities until 1994, when they merged to form the Deutsche Bahn. Organisation The DR was the largest employer in the GDR and as a state-owned firm was directly subordinated to the GDR Ministry of Transport ''(Ministerium für Verkehr der DDR)''. From November 1954 until November 1989, the GDR Minister ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Germany
East Germany, officially the German Democratic Republic (GDR; german: Deutsche Demokratische Republik, , DDR, ), was a country that existed from its creation on 7 October 1949 until its dissolution on 3 October 1990. In these years the state was a part of the Eastern Bloc in the Cold War. Commonly described as a communist state, it described itself as a socialist "workers' and peasants' state".Patrick Major, Jonathan Osmond, ''The Workers' and Peasants' State: Communism and Society in East Germany Under Ulbricht 1945–71'', Manchester University Press, 2002, Its territory was administered and occupied by Soviet forces following the end of World War II—the Soviet occupation zone of the Potsdam Agreement, bounded on the east by the Oder–Neisse line. The Soviet zone surrounded West Berlin but did not include it and West Berlin remained outside the jurisdiction of the GDR. Most scholars and academics describe the GDR as a totalitarian dictatorship. The GDR was establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the mass ...
