Stellwerk Fichtengrund
Stellwerk Fichtengrund is a decommissioned railway signal box on the outskirts of Berlin in Oranienburg, Germany, formerly in the East Germany, GDR. It was built in 1964 by the GDR railway Deutsche Reichsbahn to operate the connection to, what was at the time, a secret rail track connecting the Prussian Northern Railway with the :de:Heidekrautbahn, Heidekrautbahn. The track, which was omitted from maps during the GDR period, was used to test a new Variable gauge, Telescopic Axle to allow train coaches to easily change from European to Russian track gauge. The prototype worked but was never put into mass production. Structure The Stellwerk operated a type GS II DR point control system and the structure was designed by the building department of the Deutsche Reichsbahn. The building consists of a block containing the control centre with radial viewing windows and a separate part containing the electrical :de:Relaisstellwerk, relay rooms. The construction of all walls, floors and roo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Signal Box
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...

Oranienburg
Oranienburg () is a town in Brandenburg, Germany. It is the capital of the district of Oberhavel. Geography Oranienburg is a town located on the banks of the Havel river, 35 km north of the centre of Berlin. Division of the town Oranienburg consists of nine districts: * Friedrichsthal * Germendorf * Lehnitz * Malz * Oranienburg * Sachsenhausen * Schmachtenhagen * Wensickendorf * Zehlendorf History Originally named Bötzow, the town of Oranienburg dates from the 12th century and was first mentioned in 1216. Margrave Albert the Bear (ruled 1157–1170) allegedly ordered the construction of a castle on the banks of the Havel. Around the castle stood a settlement of traders and craftsmen. In 1646, Friedrich Wilhelm I of Brandenburg married Louise Henriette of Orange-Nassau (German: ''Oranien-Nassau''). She was so attracted by the town of Bötzow that her husband presented the entire region to her. The princess ordered the construction of a new castle in the Dutch style and ...

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 Reichsbahn
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorganise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prussian Northern Railway
The Berlin Northern Railway (german: Berliner Nordbahn) is a 223-kilometre-long main line route, that runs from Berlin via Neustrelitz and Neubrandenburg to Stralsund on the Baltic Sea coast. Nowadays, long-distance and regional traffic on the Nordbahn is routed at Hohen Neuendorf onto the Berlin Outer Ring to the Karower Kreuz and on to Berlin Main Station or Berlin-Lichtenberg. History Construction of the line was preceded by decades of planning from 1843 until 1870 when the newly founded ''Berlin Northern Railway Company'' (German: ''Berliner Nord-Eisenbahn-Gesellschaft'') gained the concessions from the states of Prussia and Mecklenburg-Strelitz. For financial reasons, the company was dissolved on 15 December 1875. The Prussian government acquired the unfinished railway and handed over further construction of it to the Lower Silesian-Markish Railway (''Niederschlesisch-Märkische Eisenbahn''). The opening took place in three stages: *10 July 1877: Berlin–Oranienburg–Neus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Gauge
A variable gauge system allows railway vehicles in a train to travel across a break of gauge between two railway networks with different track gauges. For through operation, a train must be equipped with special bogies holding variable gauge wheelsets containing a variable gauge axle (VGA). The gauge is altered by driving the train through a gauge changer or gauge changing facility. In effect, the track widens or narrows. As the train passes through the gauge changer, the wheels are unlocked, are moved closer together, or further apart, and are then re-locked. Installed variable gauge systems exist within the internal network of Spain, and are installed on international links between Spain/France (Spanish train), Sweden/Finland (Swedish train), Poland/Lithuania (Polish train) and Poland/Ukraine (Polish train). A system for changing gauge without the need to stop is in widespread use for passenger traffic in Spain, for services run on a mix of dedicated high-speed lines (using St ...

Track 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] |
