Karlsruhe Albtalbahnhof
The Alb Valley Railway (german: Albtalbahn) is a railway line in southern Germany that runs from Karlsruhe via Ettlingen to Bad Herrenalb with a branch to Ittersbach. The line is owned and operated, as part of the Stadtbahn Karlsruhe, by the Albtal-Verkehrs-Gesellschaft (AVG). History The Ettlingen branch line The town of Ettlingen had gained a rail connection in 1844 with the opening of the current Ettlingen West station on the Baden Mainline, but the station was far from the town and could not satisfy the needs of its population and industries. Therefore, the town pressed for a short branch line to the centre of the town. Since the Grand Duchy of Baden State Railways was not interested in the construction of the line, the town of Ettlingen requested a permit to build the line itself. On 25 August 1885, the first section of the standard gauge line was opened from Ettlingen West station to Erbprinz and this was followed on 15 July 1887 by the opening of the remaining sect ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Kingdom Of Württemberg
The Kingdom of Württemberg (german: Königreich Württemberg ) was a German state that existed from 1805 to 1918, located within the area that is now Baden-Württemberg. The kingdom was a continuation of the Duchy of Württemberg, which existed from 1495 to 1805. Prior to 1495, Württemberg was a county in the former Duchy of Swabia, which had dissolved after the death of Duke Conradin in 1268. The borders of the Kingdom of Württemberg, as defined in 1813, lay between 47°34' and 49°35' north and 8°15' and 10°30' east. The greatest distance north to south comprised and the greatest east to west was . The border had a total length of and the total area of the state was . The kingdom had borders with Bavaria on the east and south, with Baden in the north, west, and south. The southern part surrounded the Prussian province of Hohenzollern on most of its sides and touched on Lake Constance. History Frederick I Frederick II, the Duke of Württemberg (1754–1816; elev ...

Karlsruhe (district)
Karlsruhe is a ''Landkreis'' (district) in the northwest of Baden-Württemberg, Germany. Neighboring districts are (from north clockwise) Rhein-Neckar, Heilbronn, Enz, Calw, Rastatt, Germersheim, Rhein-Pfalz-Kreis and the district-free city Speyer. The urban district Karlsruhe (''Stadtkreis Karlsruhe''), which contains the City of Karlsruhe, is located in the middle of the district, and partially cuts it into a northern and a southern part. History The historic origin of the district is the ''Oberamt Karlsruhe''. In 1809 it was split into one part responsible for the city Karlsruhe (Stadtamt), and one for the surrounding municipalities (Landamt). In 1865 however both parts were merged again to the ''Bezirksamt Karlsruhe''. 1938 it was split again, this time with the district of Karlsruhe for the surrounding part, and the urban district of Karlsruhe for the urban area. In 1973 the district was enlarged by adding the complete district of Bruchsal and parts of the districts Sinshe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murg (Northern Black Forest)
The Murg is an 80.2-kilometre-long river (including its headstream, the ''Rechtmurg'') and a right tributary of the Rhine in Baden-Württemberg, Germany. It flows through the Northern Black Forest into the Upper Rhine Plain, crossing the counties of Landkreis Freudenstadt, Freudenstadt and Landkreis Rastatt, Rastatt. Geography Course The Murg valley is one of the largest and deepest valleys in the Black Forest (up to over 700 metres deep) and generally runs in a northerly direction. It separates the precipitation-rich main crest of the Northern Black Forest, including the Hornisgrinde (1,164 m), to the west, from the densely forested bunter sandstone plateaux in the east. The Murg originates from 2 large headstreams in the western part of the municipality of Baiersbronn. Below the Schliffkopf at about , the main headstream of the Right Murg (''Rechtmurg'') is formed by the Schurbach stream and Tränkenteich pond, a little above the ''Murgursprung'' ("Murg Source").

Rhine Railway (Baden)
The Rhine Railway (german: Rheinbahn) is a railway line in the German state of Baden-Württemberg, running from Mannheim via Karlsruhe to Rastatt, partly built as a strategic railway and formerly continuing to Haguenau in Alsace, now in France. It was opened in 1870 as an alternative to the Baden Mainline and runs mostly broadly parallel with the Rhine Valley Railway, which runs from Mannheim to Heidelberg, Karlsruhe, Rastatt, Offenburg and Basel. The Rhine Railway originally ran from Graben-Neudorf to Karlsruhe via a more westerly route than the current route, which is now named the Hardt Railway and is partly used by lines S 1 and S 11 of the Karlsruhe Stadtbahn. In 1895 the current route was opened to Karlsruhe and extended to Rastatt and Haguenau. The section over the border along the Rhine in France was closed in 1966. Route The line is entirely within the Upper Rhine Plain. Therefore, it is almost straight and has no major engineering structures. From Karlsruhe Central Stat ...

Karlsruhe Central Station
Karlsruhe Hauptbahnhof is a railway station in the German city of Karlsruhe. The station is classified as a Category 1 station, as it is a major hub where several railways connect. History Old station When the Baden Mainline was built between Mannheim and Basel, the original Karlsruhe station was built on Kriegsstraße between Ettlinger Tor and Mendelssohnplatz about 500 metres south of Karlsruher Marktplatz, the central square of Karlsruhe. The station was designed by Friedrich Eisenlohr and it was opened on 1 April 1843 with two platforms. From the beginning, it was designed as a through station. South of the station there was a locomotive depot and to its east there was a freight yard and a central workshop. It was built to Irish gauge (), as were all railways built by the Grand Duchy of Baden State Railway in the early days. It was converted to standard gauge in 1855. In the following years other routes were connected to Karlsruhe station: in 1859 the line to Stuttgar ... [...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 ...

Fossil-fuel Power Station
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The wikt:prime mover, prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat. Fossil fuel power stations provide most of the electrical energy used in the world. Some fossil-fired power stations are designed for continuous operation as baseload power plants, while others are used as peaker plants. However, starting from the 2010s, in many countries plants designed for bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Dual Gauge
In railway engineering, "gauge" is the transverse distance between the inner surfaces of the heads of two rails, which for the vast majority of railway lines is the number of rails in place. However, it is sometimes necessary for track to carry railway vehicles with wheels matched to two different gauges. Such track is described as dual gauge – achieved either by addition of a third rail, if it will fit, or by two additional rails. Dual-gauge tracks are more expensive to configure with signals and sidings, and to maintain, than two separate single-gauge tracks. It is therefore usual to build dual-gauge or other multi-gauge tracks only when necessitated by lack of space or when tracks of two different gauges meet in marshalling yards or passenger stations. Dual-gauge tracks are by far the most common configuration, but triple-gauge tracks have been built in some situations. Background The rail gauge is the most fundamental specification of a railway.
