Vectron (locomotive)
The Vectron is a locomotive series made by Siemens Mobility, introduced at the 2010 InnoTrans trade fair in four prototype versions: diesel, multi-system, and both AC and DC electric power. The diesel version has been replaced in 2018 by a dual mode locomotive which is powered by electricity on electrified sections of the track and can be switched to diesel mode on non-electrified sections. The Vectron series is reconfigurable and modular, with a Bo'Bo' wheel arrangement, and is intended as the successor to the EuroSprinter family of locomotives. It can be configured to use any or all of the four electric power systems commonly used in Europe. A more affordable, basic version called Smartron was introduced in 2018. Background and design Around the end of the 20th century and the beginning of the 21st century Siemens successfully produced freight and passenger/universal versions of its EuroSprinter locomotive platform; initially made as single voltage machines for European stat ...

Three-phase Electric Power
Three-phase electric power (abbreviated 3ϕ) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by several people. In three-phase power, the voltage on each wire is 120 degrees phase shifted relative to each of the other wires. Because it is an AC system, it allows the voltages to be easily stepped up using transformers to high voltage for transmission and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line-to-ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 KV AC
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 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 required under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance to live parts.

Wegberg-Wildenrath Test And Validation Centre
The Wegberg-Wildenrath Test and Validation Centre () is a railway test centre owned by Siemens Mobility, Siemens near Wildenrath in North Rhine-Westphalia, Germany. History The centre is located on the site of the former RAF Wildenrath British military airfield. After the airfield closed in 1992, it was taken over by Siemens Mobility, Siemens which opened the test and validation centre in June 1997. It had five tracks over . By 2007, the railway test tracks had taken over considerable areas of the airfield, with all but the western threshold and overrun of the runway obliterated. The north-east dispersal is completely taken over by sidings, workshops and loops. Of the southern dispersals, the central and eastern are bisected by the main railway oval test track. There are ovals of track for testing trains, and various electrification systems. The test track is connected to the rest of the German railway network by a long branch line to the German portion of the Iron Rhine freigh ...

MTU Friedrichshafen
MTU Friedrichshafen GmbH, trading as MTU Solutions (stylised as mtu Solutions) is a German manufacturer of commercial internal combustion engines founded by Wilhelm Maybach and his son Karl Maybach in 1909. Wilhelm Maybach was the technical director of Daimler-Motoren-Gesellschaft (DMG), a predecessor company of the German multinational automotive corporation Daimler AG, until he left in 1907. On 23 March 1909, he founded the new company, Luftfahrzeug-Motorenbau GmbH (Aircraft Engine Manufacturing Corp), with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH (Maybach Engine Manufacturing Corp), which originally developed and manufactured diesel and petrol engines for Zeppelins, and then railcars. The Maybach Mb.IVa was used in aircraft and airships of World War I. The company first built an experimental car in 1919, with the first production model introduced two years later at the Berlin Motor Show. Between 1921 and 1940, t ...

Multiple Working
On the rail network in Great Britain, multiple working is where two or more traction units (locomotives, diesel multiple units or electric multiple units) are coupled together in such a way that they are all under the control of one driver ( multiple-unit train control). If the front locomotive of a pair in multiple has failed the driver can still control the rear locomotive for as long as air and electricity supplies are available on the failed locomotive. "In tandem" is when more than one diesel or electric locomotive are hauling a single train and under the control of a driver on each locomotive. Locomotives In the early days of diesel locomotives in the 1960s, locomotives worked within their class (i.e. two locomotives of the same class could work together but not with other classes). Locomotives from different manufacturers had varying methods of controlling engines or braking systems. If a train required more than one locomotive, an additional driver was needed, a ...

Wheelset (rail Transport)
A wheelset is a pair of railroad car, railroad vehicle Train wheel, wheels mounted rigidly on an Axle#Vehicle axles, axle. Wheelsets are often mounted in a bogie ("List of railroad truck parts, truck" in North America) – a pivoted frame assembly holding at least two wheelsets – at each end of the vehicle. Most modern goods wagon, freight cars and Railroad car#Passenger cars, passenger cars have bogies each with two wheelsets, but three wheelsets (or more) are used in bogies of freight cars that carry heavy loads, and three-wheelset bogies are under some passenger cars. Four-wheeled goods wagons that were once near-universal in Europe and Great Britain and their colonies have only two wheelsets; in recent decades such vehicles have become less common as trainloads have become heavier. Conical wheel-tread Most train wheels have a cone (mathematics), conical taper of about 1 in 20 to enable the wheelset to follow Civil engineering#Surveying, curves with less ...

Buffer Beam
A headstock of a rail vehicle is a transverse structural member located at the extreme end of the vehicle's underframe. The headstock supports the coupling at that end of the vehicle, and may also support buffers, in which case it may also be known as a buffer beam. The headstocks form part of the underframe of a locomotive or a railroad car. The headstocks of locomotives, railcars and cabcars also support headlamps and the hoses for air brakes, vacuum brakes as well as the cables for train control and head end power. Length over headstocks A commonly used measurement relating to a rail vehicle is its length over headstocks, which is the length of the vehicle excluding its couplings or buffers (if any). Alternative expressions for length over headstocks are length over coupler pulling faces, usually applied to Janney couplers, and length over buffers.

Sill Plate
A sill plate or sole plate in construction and architecture is the bottom horizontal member of a wall or building to which vertical members are attached. The word "plate" is typically omitted in America and carpenters speak simply of the "sill". Other names are rat sill, ground plate, ground sill, groundsel, night plate, and midnight sill. Sill plates are usually composed of lumber but can be any material. The timber at the top of a wall is often called a top plate, pole plate, mudsill, wall plate or simply "the plate". Timber sills In historic buildings the sills were almost always large, solid timbers framed together at the corners, carry the Bent (structural), bents, and are set on the stone or brick foundation walls, Pier (architecture), piers, or piles (wood posts driven or set into the ground). The sill typically carries the wall framing (posts and studs) and floor joists. There are rare examples of historic buildings in the U.S. where the floor joists land on the founda ...
