Hamburg-Altona Link Line
The Hamburg-Altona link line (german: Hamburg-Altonaer Verbindungsbahn) is a railway line in Hamburg, Germany. It now connects the lines from the north and west of Hamburg and Altona station with Hamburg Hauptbahnhof and the lines to the south and east. It was initially designed as a freight line only but is it 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 this line was extended to Berlin. Two years later, the Altona-Kiel Railway Company opened a 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 the stations. The route of the line is affected st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current which 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, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''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. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

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 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 ...

Berlin S-Bahn
The Berlin S-Bahn () is a rapid transit railway system in and around Berlin, the capital city of Germany. It has been in operation under this name since December 1930, having been previously called the special tariff area ''Berliner Stadt-, Ring- und Vorortbahnen'' (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 electrification of large parts of the network, a number of lines remained under steam. Today, the term ''S-Bahn'' is used in Berlin only for those lines and trains with third-rail electrical power transmission and the special Berlin S-Bahn loading gauge. The third unique technical feature of the Berlin S-Bahn, the , is being phased out and replaced by a communications-based train control ...

Overhead Lines
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 are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (german: Reichsbahnausbesserungswerk Berlin-Schöneweide, ''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 tur ...

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., " 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 reference to a mythical "Royal Prussian ... [...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 line and the 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 Ohlsdorf–Blankenese line. Planned as an electric railway with overhead lines, the trains were first 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 airport. This was discontinued when a new station was constructed in the airport. An S-Bahn maintenance depot is located south-east of the station. Services Ohlsdorf is ...

Barmbek Station
Barmbek is a railway station and transport hub in Hamburg, Germany, for the underground railway (U-Bahn) system and the suburban railway (S-Bahn) system. The station is located in the district of Barmbek-Nord, Germany. Barmbek-Nord is part of the borough of Hamburg-Nord. The suburban railway part of the station at the north side is listed as ''Barmbek (S-Bahn)'', No. 0376 and category 4 by the Deutsche Bahn. The DS 100 code is ABAG. History In November 1866, a Barmbek line was built for horsecars by the ''Hamburger Pferde-Eisenbahn-Gesellschaft'' (Hamburg horsecar railway company). On 11 April 1895, the first new built electric tram line was opened from ''Barmbeker Zoll'' (Barmbek customs facilities) to Ohlsdorf Cemetery, and on 6 December 1906, the ''Hamburg-Altonaer Stadt- und Vortbahn'' (City and suburban railway) — since 1934 abbreviated Hamburg S-Bahn — opened the double track line Ohlsdorf – Blankenese, including Barmbek station.

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 to b ...
