British Rail Class 42
The British Rail Class 42 ''Warship'' diesel-hydraulic locomotives were introduced in 1958. It was apparent at that time that the largest centre of expertise on diesel-hydraulic locomotives was in West Germany. The Western Region of British Railways negotiated a licence with German manufacturers to scale down the German Federal Railway's "V200" design to suit the smaller loading gauge of the British network, and to allow British manufacturers to construct the new locomotives. The resultant design bears a close resemblance, both cosmetically and in the engineering employed, to the original V200 design. Warship locomotives were divided into two batches: those built at BR's Swindon works were numbered in the series D800-D832 and D866-D870, had a maximum tractive effort of and eventually became British Rail Class 42. 33 others, D833–D865, were constructed by the North British Locomotive Company and became British Rail Class 43. They were allocated to Bristol Bath Road, Plymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Somerset Railway
The West Somerset Railway (WSR) is a heritage railway line in Somerset, England. The freehold of the line and stations is owned by Somerset County Council; the railway is leased to and operated by West Somerset Railway plc (WSR plc); which is supported and minority-owned by charitable trust the West Somerset Railway Association (WSRA) and the West Somerset Steam Railway Trust (WSSRT). The WSR plc operates services using both heritage steam and diesel trains. It originally opened in 1862 between and . In 1874 it was extended from Watchet to by the Minehead Railway. Although just a single line, improvements were needed in the first half of the twentieth century to accommodate the significant number of tourists that wished to travel to the Somerset coast. The line was closed by British Rail in 1971 and reopened in 1976 as a heritage line. It is the longest standard gauge independent heritage railway in the United Kingdom. Services normally operate over just the between Mine ... [...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 ...

Exeter To Plymouth Line
Exeter () is a city in Devon, South West England. It is situated on the River Exe, approximately northeast of Plymouth and southwest of Bristol. In Roman Britain, Exeter was established as the base of Legio II Augusta under the personal command of Vespasian. Exeter became a religious centre in the Middle Ages. Exeter Cathedral, founded in the mid 11th century, became Anglican in the 16th-century English Reformation. Exeter became an affluent centre for the wool trade, although by the First World War the city was in decline. After the Second World War, much of the city centre was rebuilt and is now a centre for education, business and tourism in Devon and Cornwall. It is home to two of the constituent campuses of the University of Exeter: Streatham and St Luke's. The administrative area of Exeter has the status of a non-metropolitan district under the administration of the County Council. It is the county town of Devon and home to the headquarters of Devon County Council. A p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GWR 4073 Class
The 4073 or Castle Class are 4-6-0 steam locomotives of the Great Western Railway, built between 1923 and 1950. They were designed by the railway's Chief Mechanical Engineer, Charles Collett, for working the company's express passenger trains. They could reach speeds of up to . Background The origins of this highly successful design date back to the Star Class of 1907 which introduced the basic 4-cylinder 4-6-0 layout with long-travel valves and Belpaire firebox that was to become characteristic of Great Western Railway (GWR) express passenger locomotives. The Star class was designed to take the top express trains on the GWR, with 61 in service by 1914, but after World War I there was a need for an improved design. To meet this need, Chief Mechanical Engineer George Churchward had in mind an enlarged Star class design with a standard No.7 boiler, as fitted to his GWR 4700 Class express freight 2-8-0. However, this combination would have taken the axle load over the 20-ton limit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GWR 6000 Class
The Great Western Railway (GWR) 6000 Class or King Class is a class of 4-6-0 steam locomotives designed for express passenger work and introduced in 1927. They were the largest locomotives built by the GWR, apart from the unique Pacific ( ''The Great Bear''). The class was named after kings of the United Kingdom and of England, beginning with the then reigning monarch, King George V, and going back through history. They handled the principal GWR expresses on the main line from London to the West of England and on the Chiltern line to Birmingham and Wolverhampton, until 1962 when the class was withdrawn. Background and development By 1918, it was apparent to the GWR chief mechanical engineer George Jackson Churchward that his Star Class 4-6-0 locomotives would soon be incapable of handling the heaviest West of England expresses without assistance. He therefore proposed fitting the diameter boiler used on his 4700 Class 2-8-0 on to a 4-6-0 chassis, in 1919, to create a more ...

Old Oak Common TMD
Old Oak Common TMD was a traction maintenance depot located west of Paddington railway station, London Paddington, in Old Oak Common. The depot was the main facility for the storage and servicing of locomotives and multiple-units from Paddington railway station, Paddington. The depot codes were OC for the diesel depot and OO for the carriage shed. In steam days the List of British Railways shed codes, shed code was 81A. The area is also where two Great Western Railway main lines divide: the 1838 route to via , and the 1906 "New North Main Line" (present-day Acton–Northolt line) via to South Ruislip station, Northolt Junction, the start of the Great Western and Great Central Joint Railway line. The former is in use for regular passenger services; the latter is used overwhelmingly by freight trains and empty coaching stock movements. The 'HST' section of Old Oak Common TMD, more commonly known as 'Old Oak Common HST Depot' closed in 2018 with the removal of the InterCity 125s ...

Newton Abbot Engine Shed
Newton Abbot railway station serves the town of Newton Abbot in Devon, England. It is from London, measured from the zero point at to the junction for the branch to . The station today is managed by Great Western Railway, who provide train services along with CrossCountry. For many years, it was also the junction for the branch line to Moretonhampstead and the site of a large locomotive workshop. History Broad gauge The station was opened by the South Devon Railway Company on 30 December 1846 when its line was extended from Teignmouth railway station. It was opened through to on 20 June 1847 and a branch to Torquay was added on 18 December 1848. The Moretonhampstead and South Devon Railway opened its branch line on 26 June 1866. All these railways used the broad gauge. Approaching the station from the town along Queen Street, people first saw the large goods shed. On the opposite side of the line was the pumping house for the atmospheric railway system that powered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laira TMD
Laira T&RSMD is a railway traction and rolling stock maintenance depot situated in Plymouth, Devon, England. The depot is operated by Great Western Railway and is mainly concerned with the overhaul and daily servicing of their fleet of High Speed Trains and also the DMUs used on local services. The depot code "LA" is used to identify rolling stock based there. After sixty years as a steam depot, servicing locomotives used on the Exeter to Plymouth line that runs past the shed as well as local lines, diesels started to arrive in 1958. A diesel depot opened in 1962 and was expanded in 1981 to accommodate the High Speed Trains. History Steam shed Laira was the location of the temporary terminus of the South Devon Railway from 5 May 1848 when a small engine shed would have been provided. With the completion of the line to Plymouth Millbay railway station on 2 April 1849 a new shed was provided there and the facilities at Laira dismantled, although it remained a junction f ...

Bristol Bath Road TMD
Bristol Bath Road depot was a railway traction maintenance depot in central Bristol, England, which was in use from 1852 until 1995. History The Bristol and Exeter Railway opened workshops at Bath Road in January 1852. 35 locomotives were built in the workshops between 1859 and 1876. Part of the site was an engine shed with six tracks. It was rebuilt under the Loans and Guarantees Act (1929) in 1934 by the Great Western Railway. The site's scale meant that although the depot was to be the major repair and maintenance point for the Bristol divisional area, the shed was restricted to a steel-frame straight 8-road with northernlight roof pattern form, as opposed to the GWR standard-pattern turntable model like Old Oak Common. Secondly, as the depot was so close to Bristol Temple Meads, it was required to keep the depot in full operation while construction took place. The twin-ramp coal stage was of standard GWR pattern but used concrete beams and brick piers to restrict ramp width. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 43 (Warship Class)
The British Rail Class 43 diesel-hydraulic locomotives were built by the North British Locomotive Company (NBL) from 1960 to 1962. They were numbered D833–D865. Classification The D800 series diesel-hydraulic 'Warship Class', of UIC classification, B-B wheel arrangement, was constructed by two different builders. Those locomotives built by British Railways at Swindon railway works, Swindon Works were originally numbered D800-D832 and D866-D870. They were allocated Class 42 under the 1968 classification system, while those built by the North British Locomotive Company (NBL) were originally numbered D833-D865 and allocated Class 43. Because of their early withdrawal dates, neither the Swindon- nor the NBL-built locomotives carried TOPS numbers. More detail on factors common to both types can be found in the article on the Swindon-built British Rail Class 42. Mechanical details The NBL-built D800s differed mechanically from the Swindon-built batch: the Swindon locomotives us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North British Locomotive Company
The North British Locomotive Company (NBL, NB Loco or North British) was created in 1903 through the merger of three Glasgow locomotive manufacturing companies; Sharp, Stewart and Company (Atlas Works), Neilson, Reid and Company (Hyde Park Works) and Dübs and Company (Queens Park Works), creating the largest locomotive manufacturing company in Europe and the British Empire. Its main factories were located at the neighbouring Atlas and Hyde Park Works in central Springburn, as well as the Queens Park Works in Polmadie. A new central Administration and Drawing Office for the combined company was completed across the road from the Hyde Park Works on Flemington Street by James Miller in 1909, later sold to Glasgow Corporation in 1961 to become the main campus of North Glasgow College (now Glasgow Kelvin College). The two other Railway works in Springburn were St. Rollox railway works, owned by the Caledonian Railway and Cowlairs railway works, owned by the North British Railway ...

Maximum Tractive Effort
As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion. In railway engineering, the term tractive effort is often used synonymously with tractive force to describe the pulling or pushing capability of a locomotive. In automotive engineering, the terms are distinctive: tractive effort is generally higher than tractive force by the amount of rolling resistance present, and both terms are higher than the amount of drawbar pull by the total resistance present (including air resistance and grade). The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is one or ...
