GWR 6000 Class
The Great Western Railway (GWR) 6000 Class or King Class is a class of 4-6-0 steam locomotives designed for Inter-city rail, express passenger work and introduced in 1927. They were the largest locomotives built by the GWR, apart from the unique Pacific (GWR 111 The Great Bear, ''The Great Bear''). The class was named after kings of the United Kingdom and of England, beginning with the then reigning monarch, George V of the United Kingdom, King George V, and going back through history. They handled the principal GWR expresses on the Great Western Main Line, main line from London to the West of England and on the Chiltern Main Line, Chiltern line to Birmingham and Wolverhampton, until 1962 when the class was withdrawn.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 GWR 4000 Class, Star Class 4-6-0 locomotives would soon be incapable of handling the heaviest West of England expresses without assistance. ...

Bridge Stress Committee
The Bridge Stress Committee was appointed in 1923 by the UK Department of Scientific and Industrial Research under Sir Alfred Ewing, to investigate stresses in railway bridges, especially as regards the effects of moving loads. Its report, published in 1928, was very influential in British locomotive design as it enabled larger multi-cylinder locomotive classes. Background The increased weight of express trains in the United Kingdom during the first quarter of the twentieth century required larger, six-coupled locomotives, but new designs were being limited by the weight restrictions imposed on many underline bridges. On most mainlines this was restricted to no more than on any axle. However, engineers were becoming increasingly aware of the significance of ‘hammer blow’ rather than ’deadweight’ in determining the safe loads for such bridges. Committee A committee of was established in 1923, funded jointly by the UK government and the railway companies, to carry out inves ...

SR Lord Nelson Class
The SR class LN or ''Lord Nelson'' class is a type of 4-cylinder 4-6-0 steam locomotive designed for the Southern Railway by Richard Maunsell in 1926. They were intended for Continental boat trains between London (Victoria) and Dover harbour, but were also later used for express passenger work to the South-West of England. Sixteen of them were constructed, representing the most powerful (although not the most successful) Southern 4-6-0 design. They were all named after famous admirals. The class continued to operate with British Railways until withdrawn during 1961 and 1962. Only one example of the class – the first engine, ''Lord Nelson'' itself – has been saved from scrapping. This has been seen running on mainline tours and preserved railways throughout Britain. Background Although the improved ”King Arthur" class 4-6-0 locomotives were capable of the heaviest express passenger work between London and South West England, there was a growth in demand for Continental ...

Southern Railway (UK)
The Southern Railway (SR), sometimes shortened to 'Southern', was a British railway company established in the Railways Act 1921, 1923 Grouping. It linked London with the English Channel, Channel ports, South West England, Seaside resort#British seaside resorts, South coast resorts and Kent. The railway was formed by the amalgamation of several smaller railway companies, the largest of which were the London and South Western Railway (LSWR), the London, Brighton and South Coast Railway (LB&SCR) and the South Eastern and Chatham Railway (SE&CR).Bonavia (1987) pp. 26–28 The construction of what was to become the Southern Railway began in 1838 with the opening of the London and Southampton Railway, which was renamed the London & South Western Railway. The railway was noted for its astute use of public relations and a coherent management structure headed by Herbert Ashcombe Walker, Sir Herbert Walker. At , the Southern Railway was the smallest of the Big Four (British railway comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tractive Effort
In railway engineering, the term tractive effort describes the pulling or pushing capability of a locomotive. 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 more wheels in frictional contact with a railroad track. Defining tractive effort The term ''tractive effort'' is often qualified as ''starting tractive effort'', ''continuous tractive effort'' and ''maximum tractive effort''. These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction () between the driving wheels and supporting surface, and the weight applied to the driving wheels (). The product of and is the ... [...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 li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s ''Consolidation'', the name of the first 2-8-0.White, John H. Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York: Dover Publications, p. 65. The notation 2-8-0T indicates a tank locomotive of this wheel arrangement, the "T" suffix indicating a locomotive on which the water is carried in side-tanks mounted on the engine rather than in an attached tender (rail), tender. The Consolidation represented a notable advance in locomotive power. After 1875, it became "the most popular type of freight locomotive in the United States and was built in greater quantities tha ...

GWR 4700 Class
The Great Western Railway (GWR) 4700 Class was a class of nine 2-8-0 steam locomotives, designed by George Jackson Churchward. They were introduced in 1919 for heavy mixed-traffic work. Although primarily designed for fast freight, the class also sometimes hauled passenger trains, notably heavy holiday expresses in the summer months. They were unofficially nicknamed "Night Owls" because they were primarily designed to haul goods during the night and they could be seen simmering in the daylight, awaiting their nocturnal duties. Background At the end of the First World War, the running department of the GWR identified the need for a larger version of the successful GWR 4300 Class 2-6-0 incorporating the Swindon No. 1 boiler. They envisaged a smaller version of the successful Saint class 4-6-0 with driving wheels - the intermediate of Churchward's three standard wheel sizes, for express goods trains. However, Churchward preferred a 2-8-0 design for this purpose. Prototype The p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GWR 4000 Class
The Great Western Railway 4000 or Star were a class of 4-cylinder 4-6-0 passenger steam locomotives designed by George Jackson Churchward for the Great Western Railway (GWR) in 1906 and introduced from early 1907. The prototype was built as a 4-4-2 Atlantic (but converted to 4-6-0 during 1909). They proved to be a successful design which handled the heaviest long-distance express trains, reaching top speeds of 90 mph (145 km/h), and established the design principles for GWR 4-cylinder classes over the next twenty-five years. Background After finally converting the last broad gauge lines in 1892, the GWR began a period of modernisation as new cut-off lines shortened its routes to west of England, South Wales and Birmingham. During the first decade of the twentieth century, the new Chief Mechanical Engineer, George Jackson Churchward designed or acquired a number of experimental locomotives with different wheel arrangements and boiler designs to help him plan for the fut ...
