Siemens EuroSprinter
The EuroSprinter family of electric locomotives is a modular concept of locomotives for the European market built by Siemens Mobility. The internal Siemens product name is ES 64, with ES for EuroSprinter and the number 64 indicating the 6,400 kW power at rail. Additional information is given in the name on the usage (U as universal, P as prototype and F as freight) and on the number of electric power systems supported (e. g. 2 as two types, 4 as all four systems commonly used in Europe). Development The first prototype ES 64 P was built in 1992, as Deutsche Bahn AG was expected to issue a large order of locomotives as a replacement for the ageing Einheits-Elektrolokomotiven. The external appearance was similar to the earlier Siemens/Krauss-Maffei made dual voltage Spanish RENFE Class 252, delivered in 1991, which in turn used three phase asynchronous drive technology introduced with the DB Class 120. The prototype was used for extensive tests in some countries in Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krauss-Maffei
KraussMaffei is a German manufacturer of injection molding machines, machines for plastics extrusion technology, and reaction process machinery. It was acquired by ChemChina in 2016. History Locomotives KraussMaffei was formed in 1931 from a merger of the two Munich firms of Maffei (founded 1838) and Krauss & Co. (founded 1860). Both belonged to the leading German makers of locomotives of various types. Maffei also built other steam-operated vehicles and, later, manufactured vehicles with combustion engines, including locomotives, trolleybuses and buses until the 1950s. The headquarters of the firm remained in Munich. In the 1960s, KraussMaffei built several examples of the ML 4000 C′C′ diesel-hydraulic locomotive for demonstration and testing on American railroads. Southern Pacific and Denver & Rio Grande Western Railroad participated in the tests, but both found the locomotives unsuitable for service in the rugged Rocky Mountains through which the two railroads ran.

ÖBB
The Austrian Federal Railways (german: Österreichische Bundesbahnen, formally (lit. "Austrian Federal Railways Holding Stock Company") and formerly the or ''BBÖ''), now commonly known as ÖBB, is the national railway company of Austria, and the administrator of Liechtenstein's railways. The ÖBB group is owned entirely by the Republic of Austria, and is divided into several separate businesses that manage the infrastructure and operate passenger and freight services. The Austrian Federal Railways has had two discrete periods of existence. It was first formed in 1923, using the ''Bundesbahn Österreich'' name, as a successor to the Imperial Royal Austrian State Railways (kkStB), but was incorporated into the ''Deutsche Reichsbahn'' during the 1938–1945 Anschluss. It was reformed in 1947, under the slightly different name ''Österreichische Bundesbahnen'', and remains in existence in this form. Major changes currently being made to the Austrian railway netwo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GySEV
The Raaberbahn or GYSEV is a Hungarian-Austrian railway company based in Sopron, Hungary. The company is a joint enterprise of the states of Hungary (65.6%), Austria (28.2%), and a holding belonging to (4.9%). In Hungarian it is called the (GYSEV), and in German it was known as the (ROeEE) until 2008, when the name was changed to Raaberbahn. History The operation of the company was requested in 1872 by Baron Viktor Erlanger. It is sanctioned by law. The constituent general meeting of the company was held on 1 February 1875 in |
Hungarian State Railways
Hungarian State Railways ( hu, Magyar Államvasutak, MÁV) is the Hungarian national railway company, with divisions "MÁV START Zrt." (passenger transport), "MÁV-Gépészet Zrt." (maintenance), "MÁV-Trakció Zrt." and "MÁV Cargo Zrt" (freight transport). The head office is in Budapest. History 1846–1918 Construction of Hungary's first railway line began in the second half of 1844. The first steam locomotive railway line was opened on 15 July 1846 between Pest and Vác. This date is regarded as the birth date of the Hungarian railways. The Romantic poet Sándor Petőfi rode on the first train and wrote a poem predicting that rails would connect Hungary like blood vessels in the human body. After the failed revolution, the existing lines were nationalized by the Austrian State and new lines were built. As a result of the Austro-Sardinian War in the late 1850s, all these lines were sold to Austrian private companies. During this time the company of Ábrahám Gan ...

Quill Drive
A quill is a writing tool made from a moulted flight feather (preferably a primary wing-feather) of a large bird. Quills were used for writing with ink before the invention of the dip pen, the metal-Nib (pen), nibbed pen, the fountain pen, and, eventually, the ballpoint pen. As with the earlier reed pen (and later dip pen), a quill has no internal ink reservoir and therefore needs to periodically be dipped into an inkwell during writing. The hand-cut goose quill is rarely used as a Western calligraphy, calligraphy tool anymore because many papers are now derived from Pulp (paper), wood pulp and would quickly wear a quill down. However, it is still the tool of choice for a few scribes who have noted that quills provide an unmatched sharp stroke as well as greater flexibility than a steel pen. Description The shaft of a flight feather is long and hollow, making it an obvious candidate for being crafted into a pen. The process of making a quill from a feather involves Curing (che ...

Swiss Federal Railways
Swiss Federal Railways (german: link=no, Schweizerische Bundesbahnen, ''SBB''; french: link=no, Chemins de fer fédéraux suisses, ''CFF''; it, Ferrovie federali svizzere, ''FFS'') is the national railway company of Switzerland. It is usually referred to by the initials of its German, French, and Italian names, either as SBB CFF FFS, or used separately. The Romansh version of its name, ''Viafiers federalas svizras'', is not officially used. The official English abbreviation is "SBB", instead of the English acronym such as "SFR", which stands for ''Swiss Federal Railways'' itself. The company, founded in 1902, is headquartered in Bern. It used to be a government institution, but since 1999 it has been a special stock corporation whose shares are held by the Swiss Confederation and the Swiss cantons. It is currently the largest rail and transport company of Switzerland, and operates on most standard gauge lines of the Swiss network. It also heavily collaborates with ...

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 ...

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 ...

25 KV AC Railway Electrification
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons why it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance distances required where it ran under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance t ...

15 KV AC Railway Electrification
Railway electrification systems using at are used on transport railways in Germany, Austria, Switzerland, Sweden, and Norway. The high voltage enables high power transmission with the lower frequency reducing the losses of the traction motors that were available at the beginning of the 20th century. Railway electrification in late 20th century tends to use AC systems which has become the preferred standard for new railway electrifications but extensions of the existing networks are not completely unlikely. In particular, the Gotthard Base Tunnel (opened on 1 June 2016) still uses 15 kV, 16.7 Hz electrification. Due to high conversion costs, it is unlikely that existing systems will be converted to despite the fact that this would reduce the weight of the on-board step-down transformers to one third that of the present devices. History The first electrified railways used series-wound DC motors, first at 600 V and then 1,500 V. Areas with 3 kV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
