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 ...

Railway Locomotive
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first us ...

British Rail 18100
British Rail 18100 was a prototype main line gas turbine-electric locomotive built for British Railways in 1951 by Metropolitan-Vickers, Manchester. It had, however, been ordered by the Great Western Railway in the 1940s, but construction was delayed due to World War II. It spent its working life on the Western Region of British Railways, operating express passenger services from Paddington station, London. Overview It was of Co-Co wheel arrangement and its gas turbine was rated at . It had a maximum speed of and weighed . It was painted in BR black livery, with a silver stripe around the middle of the body and silver numbers. Technical details The gas turbine was of a type which would now be called a turboshaft engine but it differed from modern free-turbine turboshaft engines in having only one turbine to drive both the compressor and the output shaft. It was based on aircraft practice and had six horizontal combustion chambers (spaced radially around the turbine shaft) and ...

Polythene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visqueen
Visqueen is a brand of polyethylene plastic sheeting (typically low-density polyethylene) produced by British Polythene Industries Limited. It is the registered trade mark of British Polythene Limited in numerous countries throughout the world. It is commonly between 4 and 10 mils (0.004 to 0.01 in./0.1 to 0.25 mm) thick and is available in clear, opaque, blue, and black. Visqueen is used for many purposes. It is commonly used as a temporary tarpaulin, as a drop cloth when painting, to cover concrete as it sets, to line decorative ponds, and to cover the ground before applying stone or wood chips to prevent weed growth. Large (100 × 20 ft) sheets of Visqueen are used during floods to protect levees from wave wash erosion. It is often suggested for use in greenhouses. Visqueen is used as a condensation barrier inside walls when installing HVAC systems. It is also used as a ground cover in the crawl space of home foundations as a vapor barrier. The use of Visquee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Railways And Harbours Administration
The South African Railways and Harbours Administration (SAR&H) was established on 31 May 1910 with formation of the Union of South Africa by the amalgamation of the four colonial railways and all harbours in South Africa - about 11,000 kilometres of track. It would manage road transport and pipelines in South Africa. It also managed South African Airways from 1934 to 1997. It was reorganised and renamed in 1981 as the South African Transport Services (SATS). In 1990 it became Transnet. History Prior to the creation of the Union of South Africa on 31 May 1910, South Africa consisted of four colonies of the Cape, Orange River, Natal and Transvaal. The formation of the union resulted in the railways and harbours of the colonies being amalgamated under one organisation. The Central South African Railways, the Cape Government Railways, and the Natal Government Railways were all fused by an Act of Parliament. The South African Railways and Harbours Service Act, 1912 made striking by railwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SAR Class 5E1, Series 1
The South African Railways Class 5E1, Series 1 of 1959 was an electric locomotive. Between 1959 and 1961, the South African Railways placed 135 Class 5E1, Series 1 electric locomotives with a Bo-Bo wheel arrangement in mainline service. It was an upgraded and more powerful version of the Class 5E. Manufacturer The first series of the 3 kV DC Class 5E1 electric locomotive was designed and built for the South African Railways (SAR) by Metropolitan-Vickers (Metrovick) at its Bowesfield Works. Metrovick was one of the companies owned by the Associated Electrical Industries holding group (AEI) who supplied the electrical equipment. In all, 135 locomotives were delivered between 1959 and 1961, numbered in the range from E364 to E498. These were the last electric locomotives to be imported from the United Kingdom.South African Railways Index and Diagrams Electric and Diesel Locomotives, 610mm and 1065mm Gauges, Ref LXD 14/1/100/20, 28 January 1975, as amended [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Coal Board
The National Coal Board (NCB) was the statutory corporation created to run the nationalised coal mining industry in the United Kingdom. Set up under the Coal Industry Nationalisation Act 1946, it took over the United Kingdom's collieries on "vesting day", 1 January 1947. In 1987, the NCB was renamed the British Coal Corporation, and its assets were subsequently privatised. Background Collieries were taken under government control during the First and Second World Wars. The Sankey Commission in 1919 gave R. H. Tawney, Sidney Webb and Sir Leo Chiozza Money the opportunity to advocate nationalisation, but it was rejected. Coal reserves were nationalised during the war in 1942 and placed under the control of the Coal Commission, but the mining industry remained in private hands. At the time, many coal companies were small, although some consolidation had taken place in the years before the war. Formation and organisation The NCB was one of a number of public corporations cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

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 ...

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" ...
