DBAG Class 474
The DBAG Class 474/874 is a three-car electric multiple unit train for the Hamburg S-Bahn. The class 474 were built to replace the nearly-60-year-old class 471 trains. Some units have a pantograph (''474.3'') to service the 2007 opened line to Stade on an overhead catenary track. History The first series of 45 vehicles were ordered in 1994 from Linke-Hofmann-Busch as consortium leader of the Linke-Hofmann-Busch consortium and the then ABB Henschel in Salzgitter. Delivery started in 1996 and the first train was presented to the press in 1997. The second series of 58 vehicles were ordered in 1996 and delivered to Bw Hamburg-Ohlsdorf by 2001. In 2016, the first 474s were converted to 474-Plus railcars. The conversion was completed on December 20, 2021. Technology The class 474 represents a generation change in vehicles at the Hamburger S-Bahn. As before, the power is fed in via a third rail on the side of the track. The vehicles are supplied with direct current at 1,200 Volts. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stade
Stade (), officially the Hanseatic City of Stade (german: Hansestadt Stade, nds, Hansestadt Stood) is a city in Lower Saxony in northern Germany. First mentioned in records in 934, it is the seat of the district () which bears its name. It is located roughly to the west of Hamburg and belongs to that city's wider metropolitan region. Within the area of the city are the urban districts of Bützfleth, Hagen, Haddorf and Wiepenkathen, each of which have a council () of their own with some autonomous decision-making rights. Stade is located in the lower regions of the river Elbe. It is also on the German Timber-Frame Road. History The first human settlers came to the Stade area in 30,000 BC. Since 1180 Stade belonged to the Prince-Archbishopric of Bremen. In early 1208 King Valdemar II of Denmark and his troops conquered Stade. In August Valdemar II's cousin being in enmity with the king, the then Prince-Archbishop Valdemar reconquered the city only to lose it soon after ...

Passenger Information Systems
A passenger information system, or passenger information display system, is an automated system for supplying users of public transport with information about the nature and the state of a public transport service through visual, voice or other media. It is also known as a customer information system or an operational information system. Among the information provided by such systems, a distinction can be drawn between: * Static or schedule information, which changes only occasionally and is typically used for journey planning prior to departure. * Real-time information, derived from automatic vehicle location systems and changes continuously as a result of real-world events, which is typically used during the course of a journey (primarily how close the service is running to time and when it is due at a stop, as well as incidents that affect service operations, platform changes, etc.). Static information has traditionally been made available in printed form though route netw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niederelbebahn
The Lower Elbe Railway (german: Niederelbebahn or ''Unterelbebahn''), is a railway line between Hamburg and Cuxhaven in northwestern Germany, which was opened in 1881 by the ''Lower Elbe Railway Company'' (''Unterelbesche Eisenbahngesellschaft''). At 103.6 kilometres of length, the line runs close to the southern bank of the Lower Elbe river. Line features The Lower Elbe Railway is a main line since 1964 and is currently listed as Kursbuchstrecke 121. The line is part of the ''Strecke 1720'', with the kilometrage starting at Lehrte near Hanover. The line features two tracks on most sections, except between the stations Himmelpforten and Hechthausen. The line has been electrified between Hamburg and Stade since 1968. The Hamburg S-Bahn line to Neugraben runs parallel to the line since 1984; and since 2008, toward Stade, using dual-voltage vehicles. The trains between Cuxhaven and Hamburg have been operated by metronom Metronom Eisenbahngesellschaft mbH is a German no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hamburger Abendblatt
The ''Hamburger Abendblatt'' (English: ''Hamburg Evening Newspaper'') is a German daily newspaper in Hamburg. The paper focuses on news in Hamburg and area, and produces regional supplements with news from Norderstedt, Ahrensburg, Harburg, and Pinneberg. Politically the paper is mildly conservative, but usually pro-government, including during SPD administrations. History and profile Four previous Hamburg newspapers had the word ''Abendblatt'' ("Evening Newspaper") in their title, including one named the ''Hamburger Abendblatt'', founded on 2 May 1820. This incarnation of the ''Hamburger Abendblatt'', however, was first published after World War II beginning on 14 October 1948 with an initial edition of 60,000 copies. The paper received a publishing license from the Hamburg Senate and Mayor Max Brauer, making it the first daily paper of post-war Germany to receive a license from German rather than Allied occupation authorities. After about six months of operation, its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Wire Train Bus
The train communication network (TCN) is a hierarchical combination of two fieldbus for data transmission within trains. It consists of the Multifunction Vehicle Bus (MVB) inside each vehicle and of the Wire Train Bus (WTB) to connect the different vehicles. The TCN components have been standardized in IEC 61375. Multifunction vehicle bus (MVB) The multifunction vehicle bus connects individual nodes within a vehicle or in a closed train set. Unlike the WTB there is no requirement on a single international connector standard for the vehicle bus inside a coach, locomotive or train set – instead there are three predefined media and connector classes: # OGF ( optical glass fibres) uses 240 μm fibers for a line distance of 2000 m, # EMD (electrical medium distance) uses shielded twisted pair with RS 485 transmitters and transformers for galvanical isolation), for a length reaching 200 m and # ESD (electrical short distance) uses a simple backplane wiring without ga ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are usually supplied from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...

S-Bahn Hamburg
The Hamburg S-Bahn is a suburban commuter railway network in the Hamburg Metropolitan Region. Together, the S-Bahn, the Hamburg U-Bahn, the AKN railway and the regional railway form the backbone of railway public transport in the city and the surrounding area. The network has operated since 1907 as a commuter rail system, under the direction of the state railway, and is a member of the Hamburger Verkehrsverbund (HVV; Hamburg Transport Association). There are six lines, serving 68 stations, on of route. On an average working day the S-Bahn transports about 590,000 passengers; in 2010 about 221 million people used the S-Bahn. The S-Bahn is the only railway in Germany that uses both 1,200 V DC supplied by a third rail and supplied by overhead lines. Most of the tracks are separated from other rail services. The S-Bahn is operated by S-Bahn Hamburg GmbH, a subsidiary of DB Regio. Similarly to Berlin but unlike Hanover, the S-Bahn is an important part of public transport withi ...
