Hamburg-Altona Link Line
The Hamburg-Altona link line () is a railway line in Hamburg, Germany. Nowadays, it connects the lines from the north and northwest of Hamburg and Hamburg-Altona station, Altona station with Hamburg Hauptbahnhof and the lines to the southwest, south and east. Initially designed as a freight line only, it is now one of the busiest lines in Germany. It includes the suburban tracks of the Hamburg ''Stadtbahn'', originally the core of the Hamburg S-Bahn. History The first railway connection In 1842 the Hamburg-Bergedorf Railway Company opened a 16.5 km line from Hamburg to Bergedorf. In 1846 Berlin–Hamburg Railway, this line was extended to Berlin. Two years later, the Altona-Kiel Railway Company opened a Hamburg-Altona–Kiel railway, line to Kiel. There was originally no link between Altona and Hamburg, so freight moving from one line to the other had to be reloaded several times, which was time-consuming and expensive. A two-track link line was therefore built between th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, Fan (machine), fans and electric lamps into a wall socket. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', respectively, as when they modify ''Electric current, current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa (the full period is called a ''wave cycle, cycle''). "Alternating current" most commonly refers to power distribution, but a wide range of other appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alster
The Alster () is a right tributary of the Elbe river in Northern Germany. It has its source near Henstedt-Ulzburg, Schleswig-Holstein, flows somewhat southwards through much of the Free and Hanseatic City of Hamburg and joins the Elbe in central Hamburg. The Alster is Hamburg's second most important river. While the Elbe river is a tidal navigation of international significance and prone to flooding, the Alster is a non-tidal, slow-flowing and in some places, seemingly untouched idyll of nature, in other places tamed and landscaped urban open space, urban space. In the city center, the river forms two lakes, both prominent features in Hamburg's cityscape. Geography In total, the Alster is long and has an incline from 31 m to 4 m above sea level. Its drainage basin is about .#hhlex, Hans Wilhelm Eckhardt. ''Alster'' in ''Hamburg Lexikon'', p. 24 Left tributaries to the Alster are: Rönne, Alte Alster, Sielbek, Ammersbek, Drosselbek, Bredenbek (Alster), Bredenbek, Rodenbek, Lo ...

Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, 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 ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin S-Bahn
The Berlin S-Bahn () is a rapid transit railway system that services the reigon in and around Berlin, the capital city of Germany. It has been in operation under the name since December 1930, having been previously called the special tariff area ('Berlin city, orbital, and suburban railways'). It complements the Berlin U-Bahn and is the link to many outer-Berlin areas, such as Berlin Brandenburg Airport. As such, the Berlin S-Bahn blends elements of a commuter rail service and a rapid transit system. In its first decades of operation, the trains were steam-drawn; even after the railway electrification system, electrification of large parts of the network, some lines remained under steam. Today, the term ''S-Bahn'' is used in Berlin only for those lines and trains with Third rail, third-rail electrical power transmission and the special Berlin S-Bahn loading gauge. The third unique technical feature of the Berlin S-Bahn, the automated mechanical train control (works very similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Schöneweide–Spindlersfeld Branch Line
The Schöneweide–Spindlersfeld branch line is a branch line of the Berlin–Görlitz railway, which is entirely in Berlin. The four kilometre long line runs from a junction next to Schöneweide station to two other stations and is served by the Berlin S-Bahn at 20-minute intervals. Route The line begins at Schöneweide station (originally called ''Niederschöneweide-Johannisthal'') and separates from the main line and turns to the east. Shortly after passing over Adlergestell (an arterial road), which begins here, the line connects to the former Berlin-Schöneweide repair shop of the Deutsche Reichsbahn (, ''RAW Schöneweide''), now the main workshop of the Berlin S-Bahn. The line descends to ground level and passes over a level crossing over Oberspreestraße (street) to reach Oberspree station. Shortly after the station it curves slightly to the right and runs for half a kilometre straight ahead. After a further right turn it runs under the Berlin outer ring to its terminus ...

Prussian State Railways
The term Prussian state railways (German: ''Preußische Staatseisenbahnen'') encompasses those railway organisations that were owned or managed by the state of Prussia. The words "state railways" are not capitalized because Prussia did not have an independent railway administration; rather the individual railway organisations were under the control of the Ministry for Trade and Commerce or its later offshoot, the Ministry for Public Works. The official name of the Prussian rail network was ''Königlich Preußische Staatseisenbahnen'' (K.P.St.E., "Royal Prussian State Railways") until 1896, ''Königlich Preußische und Großherzoglich Hessische Staatseisenbahn'' (K.P.u.G.H.St.E., "Prussian-Hessian Railway Company, Royal Prussian and Grand-Ducal Hessian State Railways") until the end of the First World War, and ''Preußische Staatsbahn'' (P.St.B., "Prussian State Railway") until its nationalization in 1920. A common mistake is the use of the abbreviation K.P.E.V. in supposed refere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohlsdorf Station
Ohlsdorf is a railway station in Hamburg, Germany, located at the junction of the Hamburg-Altona link line with the Alster Valley Railway, Alster Valley line and the Hamburg Airport S-Bahn line, Hamburg Airport line in Ohlsdorf, Hamburg near the Ohlsdorf Cemetery. History On 6 December 1906, the ''Hamburg-Altonaer Stadt- und Vorortbahn'' (City and suburban railway) — later abbreviated Hamburg S-Bahn — opened the double track Hamburg-Altona link line, Ohlsdorf–Blankenese line. Planned as an electric railway with overhead lines, the trains were first Steam engine, steam powered, because of difficulties concerning the construction of the electrical installations and a delay delivering the engines. Overhead lines were completed by , however, electric operation only started on 29 January 1908. Prior to 2008, Ohlsdorf had a bus shuttle service to bring passengers from the station to the Hamburg Airport, airport. This was discontinued when a new station was constructed ...

Lübeck–Hamburg Railway
The Hamburg–Lübeck railway is one of the most important mainline railways of the German states of Schleswig-Holstein and Hamburg. It connects the two Hanseatic cities of Hamburg and Lübeck, and is part of the line to Denmark. The line was opened in 1865. Route The line runs the south-west from Lübeck through mostly agricultural, undulating land. The Trave river is crossed three times. The most important intermediate stop is Bad Oldesloe, where the line connects with hourly services on the line to Bad Segeberg and Neumünster, operated by Nordbahn. Between Ahrensburg and Hamburg-Rahlstedt the line runs along the Stellmoor tunnel valley. In the city of Hamburg the line crosses the rail freight bypass and then runs parallel to the S-Bahn line until Hamburg Hauptbahnhof is reached from the east. History The first plans to build a direct rail link between Hamburg and Lübeck were put forward in 1831. Because of the refusal of the Danish authorities to allow a direct line ...
