British Rail Class 122
The British Rail Class 122 diesel mechanical multiple units were built by Gloucester RC&W in 1958. Twenty single-car, double-ended driving motor vehicles, nicknamed "Bubble Cars", were built, numbered 55000–55019. These were supplemented by nine single-ended trailer vehicles, numbered 56291–56299 (some of which were later renumbered into the 54291–54299 block). Construction Operation The Class 122s were built mainly for use on the London Midland Region of British Railways, although some were also used in Scotland. They were used on a variety of lightly used lines, many of which were closed during the Beeching Axe in the 1960s including the ex- LSWR lines in West Devon and North Cornwall. Routes served included the Stourbridge Town and St Albans Abbey branch lines, as well as local services between Dundee and Arbroath. (The similar Pressed Steel Company built Class 121 single units were also used on the Western Region). During the 1990s, refurbished Class 122 unit ...

Bewdley
Bewdley ( pronunciation) is a town and civil parish in the Wyre Forest District in Worcestershire, England on the banks of the River Severn. It is in the Severn Valley west of Kidderminster and southwest of Birmingham. It lies on the River Severn, at the gateway of the Wyre Forest national nature reserve, and at the time of the 2011 census had a population of 9,470. Bewdley is a popular tourist destination and is known for the Bewdley Bridge, designed by Thomas Telford, and the well preserved Georgian riverside. Town geography The main part of Bewdley town is situated on the western bank of the River Severn, including the main street—Load Street. Its name derives from ''lode'', an old word for ferry. Load Street is notable for its width: it once also served as the town's market place. Most of Bewdley's shops and amenities are situated along Load Street, at the top of which lies St Anne's Church, built between 1745 and 1748 by Doctor Thomas Woodward of Chipping Campden. ...

Lostwithiel And Fowey Railway
The Lostwithiel and Fowey Railway opened in 1869 as a broad gauge railway linking the port of Fowey in Cornwall with the Cornish Main Line at Lostwithiel. Its main traffic was china clay. The company ran into financial difficulties and closed in 1880, but the line was purchased by the Cornwall Minerals Railway and reopened in 1895. A passenger service operated, but it was withdrawn in 1965, and the line reverted to the conveyance of china clay; it remains open for that traffic at the present day. Chronology * 1862 Lostwithiel and Fowey Railway Act * 1869 Line opened * 1874 Cornwall Minerals Railway opens from Par to Fowey * 1880 Service suspended * 1892 Lostwithiel and Fowey Railway Company dissolved * 1895 Reopened by Cornwall Minerals Railway * 1968 Par to Fowey line closed History Promoters of an independent company conducted negotiations with the Cornwall Railway in 1861, regarding the construction of a branch line from that railway at Lostwithiel to a location at Caffa ...

LSWR
The London and South Western Railway (LSWR, sometimes written L&SWR) was a railway company in England from 1838 to 1922. Originating as the London and Southampton Railway, its network extended to Dorchester and Weymouth, to Salisbury, Exeter and Plymouth, and to Padstow, Ilfracombe and Bude. It developed a network of routes in Hampshire, Surrey and Berkshire, including Portsmouth and Reading. The LSWR became famous for its express passenger trains to Bournemouth and Weymouth, and to Devon and Cornwall. Nearer London it developed a dense suburban network and was pioneering in the introduction of a widespread suburban electrified passenger network. It was the prime mover of the development of Southampton Docks, which became an important ocean terminal as well as a harbour for cross channel services and for Isle of Wight ferries. Although the LSWR's area of influence was not the home of large-scale heavy industry, the transport goods and mineral traffic was a major activity, and ...

Beeching Axe
The Beeching cuts (also Beeching Axe) was a plan to increase the efficiency of the nationalised railway system in Great Britain. The plan was outlined in two reports: ''The Reshaping of British Railways'' (1963) and ''The Development of the Major Railway Trunk Routes'' (1965), written by Richard Beeching and published by the British Railways Board. The first report identified 2,363 stations and of railway line for closure, amounting to 55% of stations, 30% of route miles, and 67,700 British Rail positions, with an objective of stemming the large losses being incurred during a period of increasing competition from road transport and reducing the rail subsidies necessary to keep the network running. The second report identified a small number of major routes for significant investment. The 1963 report also recommended some less well-publicised changes, including a switch to the now-standard practice of containerisation for rail freight, and the replacement of some services wit ...

London Midland Region Of British Railways
The London Midland Region (LMR) was one of the six regions created on the formation of the nationalised British Railways (BR), and initially consisted of ex-London, Midland and Scottish Railway (LMS) lines in England, Wales and Northern Ireland. The region was managed first from buildings adjacent to Euston station, and later from Stanier House in Birmingham. It existed from the creation of BR in 1948, ceased to be an operating unit in its own right in the 1980s, and was wound up at the end of 1992. Territory At its inception, the LMR's territory consisted of ex-LMS lines in England and Wales. The Mersey Railway, which had avoided being "Grouped" with the LMS in 1923, also joined the LMR. The LMR's territory principally consisted of the West Coast Main Line (WCML), the Midland Main Line (MML) south of Carlisle, and the ex-Midland Cross Country route from Bristol to Leeds. During the LMR's existence there were a number of transfers of territory to and from other regions. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Warning System
The Automatic Warning System (AWS) was introduced in the 1950s in the United Kingdom to provide a train driver with an audible warning and visual reminder that they were approaching a distant signal at caution. Its operation was later extended to give warnings for; * A colour light signal displaying a double yellow (steady or flashing), single yellow or red aspect * A reduction in permissible speed * A temporary or emergency speed restriction * An automatic barrier crossing locally monitored (ABCL), an automatic open crossing locally monitored (AOCL), or an open crossing (OC). AWS was based on a 1930 system developed by Alfred Ernest Hudd and marketed as the "Strowger-Hudd" system. An earlier contact system, installed on the Great Western Railway since 1906 and known as automatic train control (ATC), was gradually supplanted by AWS within the Western Region of British Railways. Principles of operation Information is conveyed by magnetic fields to the moving train throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leyland Motors
Leyland Motors Limited (later known as the Leyland Motor Corporation) was a British vehicle manufacturer of lorries, buses and trolleybuses. The company diversified into car manufacturing with its acquisitions of Triumph and Rover in 1960 and 1967, respectively. It gave its name to the British Leyland Motor Corporation, formed when it merged with British Motor Holdings in 1968, to become British Leyland after being nationalised. British Leyland later changed its name to simply BL, then in 1986 to Rover Group. After the various vehicle manufacturing businesses of BL and its successors went defunct or were divested, the following marques survived: Jaguar and Land Rover, now built by Jaguar Land Rover owned by TATA Motors; MG, now built by MG Motor, and Mini, now built by BMW. The truck building operation survived largely intact as Leyland Trucks, a subsidiary of Paccar. History Beginning Leyland Motors has a long history dating from 1896, when the Sumner and Spurrier fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Associated Equipment Company
Associated Equipment Company (AEC) was a British vehicle manufacturer that built buses, motorcoaches and trucks from 1912 until 1979. The name Associated Equipment Company was hardly ever used; instead it traded under the AEC and ACLO brands. During World War One, AEC was the most prolific British lorry manufacturer; after building London's buses before the great war. History Inception The London General Omnibus Company (LGOC) was founded in 1855 to amalgamate and regulate the horse-drawn omnibus services then operating in London. The company began producing motor omnibuses for its own use in 1909 with the X-type designed by its chief motor engineer, Frank Searle, at works in Blackhorse Lane, Walthamstow. The X-type was followed by Searle's B-type design, considered to be one of the first mass-produced commercial vehicles. In 1912, LGOC was taken over by the Underground Group of companies, which at that time owned most of the London Underground, and extensive tram oper ...

British United Traction
British United Traction (BUT) was a manufacturer of railway equipment and trolleybuses. It was established in 1946 as a joint venture between AEC and Leyland. History British United Traction was established in 1946 when AEC and Leyland amalgamated their trolleybus interests. Neither had produced trolleybuses since early years of World War II. With both forecasting that demand would return to pre-war levels as networks began to close, a joint venture was formed. The new company was organised so that AEC would design and produce vehicles for the UK market while Leyland looked after export markets, although there were some exceptions to this. The only noticeable difference between the manufacturers output was the wheels. Initially vehicles were produced at Leyland's Ham, London factory, with the first vehicles completed in 1947 for Johannesburg. After the factory closed 1948, production moved to AEC's Southall and Leyland's Leyland, Lancashire factories. Following AEC's acqui ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
