Adams Axle
The Adams axle is a form of radial axle for rail locomotives that enable them to negotiate curves more easily. It was invented by William Bridges Adams and patented in 1865. The invention uses axle boxes that slide on an arc in shaped horn blocks, so allowing the axle to slide out to either side. This is similar to the movement of a Bissell truck, but with the notional centre point of the curve being where the pivot of the truck would be. This design, using slide bearings, is more expensive than one employing a shaft, but takes up less space. Trials In 1865 the Society of Engineers, London, made direct comparison between the radial axle, invented by William Bridges Adams, and a bogie design with an india-rubber Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds.

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 ...

Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), 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 (rail), 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 train, 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 language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...

William Bridges Adams
William Bridges Adams (1797 – 23 July 1872) was an English author, inventor and locomotive engineer. He is best known for his patented Adams axle – a successful radial axle design in use on railways in Britain until the end of steam traction in 1968 – and the railway fishplate. His writings, including ''English Pleasure Carriages'' (1837) and ''Roads and Rails'' (1862) covered all forms of land transport. Later he became a noted writer on political reform, under the pen name ''Junius Redivivus'' ( Junius reborn); a reference to a political letter writer of the previous century. Personal life He was born and grew up in Woore, Shropshire, close to Madeley, Staffordshire, and was educated at the Madeley School. His father, the son of a yeoman farmer of Woore, moved to London where he worked his way from a journeyman coachbuilder to master tradesman. His principal business was that of supplying leather to coachmakers from a shop in Dean Street, Soho. In due course Adams was ...

Glossary Of Rail Terminology
Rail terminology is a form of technical terminology. The difference between the American term ''railroad'' and the international term ''railway'' (used by the International Union of Railways and English-speaking countries outside the United States) is the most significant difference in rail terminology. These and other terms have often originated from the parallel development of rail transport systems in different parts of the world. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist. Various global terms are presented here. Where a term has multiple names, this is indicated. The abbreviation "UIC" refers to standard terms adopted by the International Union of Railways in its official publications and thesaurus. 0–9 A B ...

Bissell Truck
A Bissell or Bissel truck (also Bissel bogie or Pony truck) is a single-axle bogie which pivots towards the centre of a steam locomotive to enable it to negotiate curves more easily. Invented in 1857 by and usually then known as a ''pony truck'', it is a very simple and common means of designing a carrying wheel. Name variants A pony truck in railway terminology, is a leading truck with only two wheels. Its invention is generally credited to Bissell, who devised one in 1857 and patented it the following year. Hence the term ''Bissel bogie'', ''Bissel truck'', or ''Bissel axle'' is used in continental Europe. In the UK, the term is Bissell truck.''Spellings" Conservative locomotive builders in Bissell's native |
Society Of Engineers UK
The Society of Engineers was a British learned society established in 1854. It was the first society to issue the professional title of Incorporated Engineer. It merged with the Institution of Incorporated Engineers (IIE) in 2005, and in 2006 the merged body joined with the Institution of Electrical Engineers to become the Institution of Engineering and Technology. History Establishment Established in May 1854 in The Strand, London, the Society of Engineers was one of the oldest professional engineering bodies in the United Kingdom (after the Smeatonian Society of Civil Engineers, 1771, the Institution of Civil Engineers, 1818, and the Institution of Mechanical Engineers, 1847) It promoted the interests of members worldwide and was concerned with all branches of engineering. It was founded by Henry Palfrey Stephenson and Robert Monro Christie as a means of reunion for former students of Putney College (the short-lived College for Civil Engineers, 1839–c.1851) ...

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.

India-rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

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 ...

North London Railway
The North London Railway (NLR) company had lines connecting the northern suburbs of London with the East and West India Docks further east. The main east to west route is now part of London Overground's North London Line. Other NLR lines fell into disuse but were later revived as part of the Docklands Light Railway, and London Overground's East London Line. The company was originally called the East & West India Docks & Birmingham Junction Railway (E&WID&BJR) from its start in 1850, until 1853. in 1909 it entered into an agreement with the London and North Western Railway which introduced common management, and the NLR was taken over completely by the LNWR in 1922. The LNWR itself became part of the LMS from the start of 1923. The railways were nationalised in 1948 and most LMS lines, including the North London route, then came under the control of the London Midland Region of British Railways.

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 ...
