Radial Axle
A radial axle is an axle on a railway locomotive or carriage which has been designed to move laterally, along the arc of a circle, when entering a curve in order to reduce the flange and rail wear. William Bridges Adams was an early developer of radial axles. Radial axles were widely used on carriages in the late 19th century before the adoption of bogies. They were also used on the leading or trailing carrying axles of locomotives, particularly tank locomotives. The idea was tried successfully by William Adams on the London and South Western Railway in 1882 in a class now known as "Adams Radials". Radial axles were also used in locomotives designed by F.W. Webb of the London and North Western Railway, and by William Stroudley and R. J. Billinton of the London Brighton and South Coast Railway. Webb's form of radial axle used a cannon box bearing A cannon bearing or cannon box bearing is an arrangement of bearings on a shaft, usually an axle, where two bearings are mounted in a ...

Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

William Adams (locomotive Engineer)
William Adams (15 October 1823 – 7 August 1904) was an English railway engineer. He was the Locomotive Superintendent of the North London Railway from 1858 to 1873; the Great Eastern Railway from 1873 until 1878 and the London and South Western Railway from then until his retirement in 1895. He is best known for his locomotives featuring the ''Adams bogie'', a device with lateral centring springs (initially made of rubber) to improve high-speed stability. He should not be mistaken for William Bridges Adams (1797–1872) a locomotive engineer who, confusingly, invented the ''Adams axle'' – a radial axle that William Adams incorporated in designs for the London and South Western Railway. History Adams was born on 15 October 1823 in Mill Place, Limehouse, London, where his father was resident engineer of the nearby East and West India Docks Company. After private schooling in Margate, Kent he was apprenticed to his father's works. The railway surveyor Charles Vignoles had p ...

London And South Western Railway
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, a ...

LSWR 415 Class
The LSWR 415 class is a 4-4-2T steam tank locomotive, with the trailing wheels forming the basis of its "Radial Tank" moniker. It was designed by William Adams and introduced in 1882 for service on the London and South Western Railway (LSWR). Originally rostered for suburban traffic, the class was soon displaced to the countryside by Dugald Drummond's M7 class. Most of the class was scrapped around the end of the First World War, and further decreases meant that all of them were due to be withdrawn by 1929. However, the class was noted for its long service on the Lyme Regis branch line, and three members of this long obsolete class were utilised on this duty until 1962, when suitable replacements became available. One has survived and can be found on the Bluebell Railway. Background This class, designed by William Adams, was the result of the work made to replace the stop-gap 46 Class on suburban services around London. In the event, they were also intended to supplemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Webb (engineer)
Francis William Webb (21 May 1836 – 4 June 1906) was an English railway engineer, responsible for the design and manufacture of locomotives for the London and North Western Railway (LNWR). Webb was born in Tixall Rectory, near Stafford, the second son of William Webb, Rector of Tixall. Career Crewe Works Showing early interest in mechanical engineering, on 11 August 1851 at the age of fifteen he was articled as a pupil of Francis Trevithick at Crewe Works.Griffiths, p.51 Webb joined the drawing office in 1856, at the end of his training. He became Chief Draughtsman on 1 March 1859. On 1 September 1861 he was appointed Works Manager at Crewe and Chief Assistant to John Ramsbottom. Whilst Works Manager Webb was responsible for the installation of Bessemer converters and the start of steel production at Crewe.

London And North Western Railway
The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. In the late 19th century, the L&NWR was the largest joint stock company in the United Kingdom. In 1923, it became a constituent of the London, Midland and Scottish (LMS) railway, and, in 1948, the London Midland Region of British Railways: the LNWR is effectively an ancestor of today's West Coast Main Line. History The company was formed on 16 July 1846 by the amalgamation of the Grand Junction Railway, London and Birmingham Railway and the Manchester and Birmingham Railway. This move was prompted, in part, by the Great Western Railway's plans for a railway north from Oxford to Birmingham. The company initially had a network of approximately , connecting London with Birmingham, Crewe, Chester, Liverpool and Manchester. The headquarters were at Euston railway station. As traffic increased, it was greatly expanded with the opening in 1849 of the Great Hall, designed by P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Stroudley
William Stroudley (6 March 1833 – 20 December 1889) was an English railway engineer, and was one of the most famous steam locomotive engineers of the nineteenth century, working principally for the London, Brighton and South Coast Railway (LB&SCR). He designed some of the most famous and longest-lived steam locomotives of his era, several of which have been preserved. Early career Born at Sandford-on-Thames, Oxfordshire, William Stroudley began work in 1847 at the local paper mill and in the same year he was apprenticed to John Inshaw's engineering firm in Birmingham. Over the next seven years he gained a variety of engineering experience on stationary engines and steam barges. From 1854 he trained as a locomotive engineer at Swindon Works under Daniel Gooch of the Great Western Railway, but soon moved to the Great Northern Railway under Charles Sacré at their Peterborough workshops, later becoming running foreman at the motive power depot there. In 1861 he was appointed m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Brighton And South Coast Railway
The London, Brighton and South Coast Railway (LB&SCR; known also as the Brighton line, the Brighton Railway or the Brighton) was a railway company in the United Kingdom from 1846 to 1922. Its territory formed a rough triangle, with London at its apex, practically the whole coastline of Sussex as its base, and a large part of Surrey. It was bounded on its western side by the London and South Western Railway (L&SWR), which provided an alternative route to Portsmouth. On its eastern side the LB&SCR was bounded by the South Eastern Railway (SER)—later one component of the South Eastern and Chatham Railway (SE&CR)—which provided an alternative route to Bexhill, St Leonards-on-Sea, and Hastings. The LB&SCR had the most direct routes from London to the south coast seaside resorts of Brighton, Eastbourne, Worthing, Littlehampton and Bognor Regis, and to the ports of Newhaven and Shoreham-by-Sea. It served the inland towns and cities of Chichester, Horsham, East Grinstead and Lewes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannon Box Bearing
A cannon bearing or cannon box bearing is an arrangement of bearings on a shaft, usually an axle, where two bearings are mounted in an enclosed tube. The function of the cannon box is to preserve the alignment of the two bearings, even if the overall tube is allowed to move. The two bearings will retain their same relative position. The bearing tube can be attached to the vehicle frame through either a pivot or springs. The name 'cannon box' derives from the appearance of the hollow tube. Also from the boring machines used to machine the accurately aligned bearing seats, the same machines developed for the boring of cannon and also used for machining the cylinders of steam engines. Cannon box bearings are still found today, although much of the need for them was removed by the development of self-aligning ball bearings. These allow the inner race of a bearing to move independently of its outer, so that each bearing can align to both shaft and housing simultaneously, even if the ...

LNWR Precedent Class
The London and North Western Railway Precedent Class was a class of seventy steam locomotives originally designed for express passenger work. History They were designed by F. W. Webb and built by the LNWR's Crewe Works between 1874 and 1882. The numbering was haphazard – while the first twenty carried "new" numbers in a solid block, the remaining fifty carried numbers formerly carried by withdrawn locomotives. All seventy carried names from new, and many of these had been used on withdrawn locomotives. Sixty-two of the locomotives were "renewed" (replaced with new locomotives carrying the same number and name) as Improved Precedent class locomotives between 1893 and 1901. The remaining eight were rebuilt as Improved Precedents in the 1890s; they retained their thick frames – the renewals had frames. Two of the unrenewed locomotives were scrapped in 1907, two in the 1910s, with four passing to the London Midland and Scottish Railway in 1923. They were allocated numbers ...
