Gross-Lichterfelde Tramway
The Gross Lichterfelde Tramway was one of the world's first electric tramways ( Miller's line was electrified in 1875). It was built by the Siemens & Halske company in Lichterfelde, a suburb of Berlin, and went in service on 16 May 1881. Overview Werner von Siemens had presented the first electric passenger train at the Berlin industrial exhibition two years before. In order to develop the concept, he received the official approval to run an electric tramway line on already existing tracks, which had been used for building the Prussian military academy (''Hauptkadettenanstalt'') at Lichterfelde West. The line started at Berlin-Lichterfelde Ost station on the Anhalt Railway line. Each car was originally equipped with a 180-volt DC traction motor, the current being supplied via the running rails, in a manner similar to that used by most present-day model railways. Therefore, the tracks were generally separated from roads, and trespassing was prohibited. At level crossings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, 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 locomotive#Transmission types, diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control DC motor, Direct-current motors with series Field coil, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metre Gauge Railways In Germany
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefiniti ...

Steglitz-Zehlendorf
Steglitz-Zehlendorf () is the sixth borough of Berlin, formed in Berlin's 2001 administrative reform by merging the former boroughs of Steglitz and Zehlendorf. Home to Free University of Berlin, the Berlin Botanical Garden, and a variety of museums and art collections, Steglitz-Zehlendorf is an important hub for research, science and culture in Berlin. It is known to be the wealthiest borough of Berlin, having the city's highest median household income. History The first mention of a present-day locality in the district by name was Lankwitz (Lancewitz) in 1239. It is assumed that Slavic and German settlements were established at the Schlachtensee and Krume Lanke lakes after 1200 at the latest. The first documented mention of Zehlendorf (then Cedelendorp) dates back to 1242. Here the Lehnin Abbey bought the settlement and kept it until 1542. Frederick the Great donated a church to the village in 1768 during a stopover on the journey from the Berlin Palace to the Sanssouci P ...

History Of Rail Transport In Germany
:''This article is part of the history of rail transport by country series'' The history of rail transport in Germany can be traced back to the 16th century. The earliest form of railways, wagonways, were developed in Germany in the 16th century. Modern German rail history officially began with the opening of the steam-powered Bavarian Ludwig Railway between Nuremberg and Fürth on 7 December 1835. This had been preceded by the opening of the horse-drawn Prince William Railway on 20 September 1831. The first long-distance railway was the Leipzig-Dresden railway, completed on 7 April 1839. Forerunners The forerunner of the railway in Germany, as in England, was to be found mainly in association with the mining industry. Mine carts were used below ground for transportation, initially using wooden rails, and were steered either by a guide pin between the rails or by flanges on the wheels. A wagonway operation was illustrated in Germany in 1556 by Georgius Agricola (image right) i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tram Transport In Germany
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as " trolley-replica buses". In the Uni ...

Elektromote
The Electromote was the world's first vehicle run like a trolleybus, which was first presented to the public on April 29, 1882, by its inventor Dr. Ernst Werner von Siemens in Halensee, a suburb of Berlin, Germany. In 1847, Siemens told his brother Wilhelm that should he have time and money, he wanted to build himself a carriage with electro-magnetic propulsion. In the early 1880s, he managed to realize the idea, first erecting the masts and infrastructure on site in 1881. Halensee, independent and not yet part of Berlin at the time, had only been named the previous year and was not yet fully developed, providing the project with the space needed as well as access via the Berlin Ringbahn at nearby Halensee station. The Elektromote operated from April 29 to June 13, 1882, on a trail-track along “Straße No. 5”, today's Joachim-Friedrich-Straße, and “Straße No. 13”, today's Johann-Georg-Straße, crossing the upper Kurfürstendamm. According to other sources, the track wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trams In Berlin
The Berlin tramway (german: Straßenbahn Berlin) is the main tram system in Berlin, Germany. It is one of the oldest tram networks in the world having its origins in 1865 and is operated by (BVG), which was founded in 1929. It is notable for being the third-largest tram system in the world, after Trams in Melbourne, Melbourne and Trams in Saint Petersburg, St. Petersburg. Berlin's tram system is made up of 22 lines that operate across a standard gauge network, with almost 800 stops and measuring almost in Network length (transport), route length and in Network length (transport)#Line length, line length. Nine of the lines, called Metrotram, operate 24 hours a day and are identified with the letter "M" before their number; the other thirteen lines are regular city tram lines and are identified by just a line number. Most of the recent network is within the confines of the former East Berlin—tram lines within West Berlin having been replaced by buses during the ...

Overhead Line
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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Circuit
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes. Definition A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors. In circuit analysis, a ''short circuit'' is defined as a connection between two nodes that forces them to be at the same voltage. In an 'ideal' ...
