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] |
Dispolok
Dispolok was a locomotive leasing company founded by Siemens in 2001 offering locomotives for hire to European rail operators. In September 2006 it was bought by Mitsui Rail Capital Europe with the brand retired in January 2008. History Due to technical problems with different locomotives, including the diesel electric Locomotive ME26 (see NSB Di 6) Siemens found itself with locomotives that had been returned from the original purchaser. In order to avoid a total loss, and with the deregulation of rail transport in Europe taking place it was decided to offer these locomotives to private companies on a leased basis. Since the new privately owned rail companies were almost all entirely new companies with no experience or infrastructure to deal with locomotive maintenance the leasing agreements included full servicing to be provided by Siemens (or its associates). In addition Siemens offer the leasers an option to buy the locomotives later if they so wished. Since the concept of o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siemens Mobility
Siemens Mobility GmbH is a separately-managed company of Siemens, arising from a corporate restructuring effective 1 August 2018. With its global headquarters in Munich, Siemens Mobility has four core business units: Mobility Management, dedicated to rail technology and intelligent traffic systems, Railway Electrification, Rolling Stock, and Customer Services. History Innovations from the late 19th century, such as the world's first electric train, when Siemens & Halske unveiled a train in which power was supplied through the rails, and the world's first electric tram, with the implementation of 2.5-kilometer-long electric tramway located in Berlin, built at the company's own expense, cemented the use of electric power in transportation systems. In the following years, inventions such as the first electric trolleybus, mine locomotives, and the first underground railway in continental Europe (in Budapest), set the path from trams and subways to today's high-speed trains.

Ă–BB
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] |
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.

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 ...

Slippery Rail
Slippery rail, or low railhead adhesion, is a condition of railways (railroads) where contamination of the railhead reduces the traction between the wheel and the rail. This can lead to wheelslip when the train is taking power, and wheelslide when the train is braking. One common cause of contamination is fallen leaves that adhere to the railhead (top surface) of railway tracks. The condition results in significant reduction in friction between train wheels and rails, and in extreme cases can render the track temporarily unusable. In Britain, the situation is colloquially referred to as "leaves on the line". Low adhesion caused by weather Railhead contamination caused by weather conditions can occur at any time of year. The leaf fall season causes the most disruption to rail operations. In heavily deciduous forested areas like the American Mid-Atlantic states, New England, many parts of Europe including the UK, and Southern Ontario, Canada, the problem can arise. Where the l ...

189 086 MIH
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

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] |
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 ...

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 ...
