British Rail Class 80
Class 80 was the TOPS classification allocated by British Rail to the prototype 25 kV AC electric locomotive. This locomotive was built by Metropolitan-Vickers, initially as a prototype gas turbine-electric locomotive, numbered 18100. British Rail allocated the number E1000 (and later E2001) to the locomotive following its conversion from gas turbine propulsion. Conversion Its new electric propulsion meant it was rated at , giving a maximum speed of and weighing . In addition, it was also converted from Co-Co to A1A-A1A wheel arrangement when the centre traction motor from each bogie was removed. The new traction motor rating (with four motors) was about the same as the original rating (with six motors). This suggests that new traction motors were fitted. The conversion of the locomotive began in January 1958 when the locomotive was moved from storage at Dukinfield Works to the Bowesfield Works at Stockton-on-Tees. The work involved the removal of the gas turbine unit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metropolitan-Vickers
Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metropolitan-Vickers F.2. Its factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world. History Metrovick started as a way to separate the existing British Westinghouse Electrical and Manufacturing Company factories from United States control, which had proven to be a hindrance to gaining government contracts during the First World War. In 1917 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A1A-A1A
The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead. The AAR system counts axles instead of wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to two powered axles in a row, "C" to three powered axles in a row, and "D" to four powered axles in a row. "1" refers to one idler axle, and "2" to two idler axles in a row. A dash ("–") separates trucks or wheel assemblies. A plus sign ("+") refers to articulation, either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of couplers. 1A-A1 "1A-A1" ...

West Coast Main Line
The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London and Glasgow with branches to Birmingham, Liverpool, Manchester and Edinburgh. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow for and was opened from 1837 to 1869. With additional lines deviating to Northampton, Birmingham, Manchester, Liverpool and Edinburgh, this totals a route mileage of . The Glasgow–Edinburgh via Carstairs line connects the WCML to Edinburgh, however the main London–Edinburgh route is the East Coast Main Line. Several sections of the WCML form part of the suburban railway systems in London, Coventry, Birmingham, Liverpool, Manchester and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns. It is one of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Region Of British Railways
The Western Region was a region of British Railways from 1948. The region ceased to be an operating unit in its own right on completion of the "Organising for Quality" initiative on 6 April 1992. The Region consisted principally of ex- Great Western Railway lines, minus certain lines west of Birmingham, which were transferred to the London Midland Region in 1963 and with the addition of all former Southern Railway routes west of Exeter, which were subsequently rationalised. History When British Railways was created at the start of 1948, it was immediately subdivided into six Regions, largely based upon pre-nationalisation ownership. The Western Region initially consisted of the former Great Western Railway system, totalling 3,782 route miles and with its headquarters at Paddington. To this was added some minor railways and joint lines in which the GWR had an interest: *Brynmawr and Western Valleys Railway *Clifton Extension Railway * Easton and Church Hope Railway *Great ...

Circuit Breaker
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household appliances, to large switchgear designed to protect high voltage circuits feeding an entire city. The generic function of a circuit breaker, or fuse, as an automatic means of removing power from a faulty system, is often abbreviated as OCPD (Over Current Protection Device). Origins An early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was to pro ...

Brown Boveri Company
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network. Activity in Britain Brown Boveri' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential transfo ...

Electrical Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromagnetic ...

Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

Stockton-on-Tees
Stockton-on-Tees, often simply referred to as Stockton, is a market town in the Borough of Stockton-on-Tees in County Durham, England. It is on the northern banks of the River Tees, part of the Teesside built-up area. The town had an estimated population of 84,318 in 2011. It is included in the Tees Valley mayoralty. The borough had a population of approximately , at the ONS The Tees was straightened in the early 1800s for larger ships to access the town. The ports have since relocated closer to the North Sea and ships are no longer able to sail from the sea to the town due to the Tees Barrage, which was installed to manage tidal flooding. The Stockton and Darlington Railway, on which coal was ferried to the town for shipment, served the port during early part of the Industrial Revolution. The railway was also the world's first permanent steam-locomotive-powered passenger railway. History Etymology ''Stockton'' is an Anglo-Saxon place name with the common ending ''ton' ...

Bowesfield Works
Bowesfield Works was a railway locomotive manufacturing plant in Stockton-on-Tees. The works was operated by a joint venture company called Metropolitan Vickers-Beyer Peacock from 1949 until 1960. Works history Metropolitan-Vickers and Beyer, Peacock & Co. formed a joint venture company in November 1949 to design and manufacture diesel, electric and gas turbine locomotives. Because Beyer, Peacock's Gorton works was still busy producing steam locomotives, an alternative site for the new locomotives to be built had to be found. A factory at Yarm Road, Stockton-on-Tees, on which Metrovicks had acquired a lease in 1947, was chosen as the location. The factory which had been built in 1946 for the American construction machinery company LeTourneau, was almost brand new, and covered an area of around , later extended to over by Metrovicks. The works had its own railway siding running from Bowesfield Junction to the north east of the works. Initially the factory was used by Metrovic ...
