Joy Valve Gear
250px, Joy Valve Gear Diagram Joy valve gear is a type of steam locomotive valve gear, designed by David Joy (3 March 1825 – 1903), Locomotive and Marine engineer, and patented (no. 929) on 8 March 1879. The British patent has not been found but the US patent (US252224 of 10 January 1882) has. Joy's gear is similar to Hackworth valve gear but has a compensating mechanism which corrects for "the slight inequality in the motion of the valve arising from the arc of the lever". The drawing (right) shows the Joy gear as applied to a London and North Western Railway locomotive. The US patent shows several modifications of the gear. In figure 6 of the patent, one of the levers has been replaced by a slide. On 10 January 1882, Mr. Joy received U.S. Patent No. 252,224 for the invention. Operation The movement is derived from a vertical link connected to the connecting rod. The vertical movement is translated into the horizontal movement required by the valve spindle by a die block m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lynton And Barnstaple Railway
The Lynton and Barnstaple Railway (L&B) was a single track (rail), single track, narrow gauge railway. It opened in May 1898 and ran for slightly more than through the area bordering Exmoor in North Devon, England. Although it opened after the Light Railways Act 1896 came into force, it was authorised and constructed before that act. It was authorised under its own Act of Parliament and built to higher (and more costly) standards than similar railways of the time. It was notable as the only narrow gauge railway in Britain that was required to use main-line standard signalling. For a short period, it earned a modest return for shareholders, but for most of its existence it made a loss.G A Brown, J D C A Prideaux, & H G Radcliffe: ''The Lynton & Barnstaple Railway'' published by David and Charles, First Edition 1964, In 1923, the L&B was taken over by the Southern Railway (UK), Southern Railway, and eventually closed in September 1935.

Ridable Miniature Railway
A ridable miniature railway (US: riding railroad or grand scale railroad) is a large scale, usually ground-level railway that hauls passengers using locomotives that are often models of full-sized railway locomotives (powered by diesel or petrol engines, live steam or electric motors). Overview Typically miniature railways have a rail track gauge between and under , though both larger and smaller gauges are used. At gauges of and less, the track is commonly raised above ground level. Flat cars are arranged with foot boards so that driver and passengers sit astride the track. The track is often multi-gauged, to accommodate , , and sometimes gauge locomotives. The smaller gauges of miniature railway track can also be portable and is generally / gauge on raised track or as / on ground level. Typically portable track is used to carry passengers at temporary events such as fêtes and summer fairs. Typically miniature lines are operated by not for profit organisations - often ...

Henry Greenly
Henry Greenly (1876–1947) was amongst the foremost miniature railway engineers of the 20th century, remembered as a master of engineering design. Miniature railways Greenly is perhaps best remembered for his miniature locomotive designs. He worked closely with many engineering companies, including Bassett-Lowke and its various engineering subsidiary companies. In 1909, along with Wenman Joseph Bassett-Lowke, Henry Greenly started and edited Model Railways and Locomotives Magazine. He worked with Captain J E P Howey on the designs for the world-famous Romney, Hythe and Dymchurch Railway in Kent, England, and served as that railway's Chief Engineer. He was also involved with innovative locomotive design work at the nearby Saltwood Miniature Railway. Greenly Engineering Models Greenly established his own miniature railway engineering company Greenly Engineering Models in Hounslow, Middlesex, and his renowned engineering design skills were well matched with the practical engineeri ...

LNWR Class G2A
The London and North Western Railway (LNWR) Class G2A was a class of steam locomotives. They were upgraded from LNWR Class G1 principally by the fitting of a higher pressure boiler. Some of the G2As subsequently received lower pressure boilers on overhaul, taking them back into Class G1. Numbering On nationalisation in 1948, British Railways (BR) received 320 G2As, thus making them the largest ex-LNWR class received by BR. They were numbered in the range 48893–49394 but the number series is not continuous because some numbers in the same range were given to G1 Class locomotives.Ian Allan ABC of British Railways Locomotives, 1948 edition, part 3, pp 39-40 Preservation None were preserved, although a very similar LNWR Class G2 No. 49395 was.

LNWR Class G2
The London and North Western Railway (LNWR) Class G2 is a class of 0-8-0 steam locomotives. 60 were built at Crewe Works in 1921–1922. Uniquely amongst classes of LNWR 8-coupled tender engines, they were not rebuilt from or into other classes. They were classified by the London, Midland and Scottish Railway (LMS) as 5, from 1928 7F. Numbering The LNWR used a lowest available number numbering system, meaning that numbers were somewhat haphazard. After the grouping in 1923, the LMS renumbered them 9395-9454 in order of build date. All were inherited by British Railways (BR) upon nationalisation Nationalization (nationalisation in British English) is the process of transforming privately owned assets into public assets by bringing them under the public ownership of a national government or state.

British Rail
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most rail transport in Great Britain from 1948 to 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. British Railways was formed on 1 January 1948 as a result of the Transport Act 1947, which nationalised the Big Four British railway companies along with some other (but not all) smaller railways. Profitability of the railways became a pressing concern during the 1950s, leading to multiple efforts to bolster performance, including some line closures. The 1955 Modernisation Plan formally directed a process of dieselisation and electrification to take place; accordingly, steam locomotives had been entirely replaced by diesel and electric traction (except for the narrow-gauge Vale of Rheidol Railway tourist lin ...

Stephenson Valve Gear
The Stephenson valve gear or Stephenson link or shifting link is a simple design of valve gear that was widely used throughout the world for various kinds of steam engines. It is named after Robert Stephenson but was invented by his employees. Historical background During the 1830s, the most popular valve drive for steam locomotives was known as ''gab valve gear, gab motion'' in the History of rail transport in Great Britain 1830–1922, United Kingdom and'' V-hook motion'' in the History of rail transportation in the United States, United States. The gab motion incorporated two sets of eccentrics and rods for each cylinder; one eccentric was set to give forward and the other backwards motion to the engine and one or the other could accordingly engage with a pin driving the distribution valve by means of the gabs: - vee-shaped ends to the eccentric rods supposed to catch the rocker driving the valve rod whatever its position. It was a clumsy mechanism, difficult to operate, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doble Steam Car
The Doble steam car was an American steam car maker from 1909 to 1931. Its latter models of steam car, with fast-firing boiler and electric start, were considered the pinnacle of steam car development. The term "Doble steam car" comprises any of several makes of steam-powered automobile in the early 20th century, including Doble Detroit, Doble Steam Car, and Doble Automobile, severally called a ''Doble'' because of their founding by Abner Doble. History There were four Doble brothers: Abner, William, John, and Warren. Their father became wealthy, patenting the Doble Pelton wheel. All were at one time associated with the automobile company, with Abner, John, and Warren as the leading lights. Abner Doble built his first steam car between 1906 and 1909 while still in high school, with the assistance of his brothers. It was based on components salvaged from a wrecked White Motor Company steamer, driving a new engine of the Doble brothers' own design. It did not run particularly ...

Russian Locomotive Class O
The Russian locomotive class O (from ) was an early type of Russian steam locomotives. 9,129 locomotives were built between 1890 and 1928; hence it was the second most numerous class of locomotive in Russia, after E class, which was a unique number even on the international level. Variants Basic variants were early Od and OD (Russian: О''д'', OД) with Joy valve gear and most numerous later OV (OВ) with Walschaerts valve gear. Some locomotives were built as two cylinder simple expansion and others as two cylinder compounds. Armoured locomotives During World War I, the Russian Civil War and the Eastern Front of World War II O-class locomotives were widely used as standard armoured locomotives in armoured trains due to rugged construction and low silhouette. Relatively lightweight, these locomotives could carry more armor without overloading the track.

Traction Engine
A traction engine is a steam engine, steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin ''tractus'', meaning 'drawn', since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway steam locomotive, locomotives – that is, steam engines that run on rails. Traction engines tend to be large, robust and powerful, but also heavy, slow, and difficult to manoeuvre. Nevertheless, they revolutionized agriculture and road haulage at a time when the only alternative Prime mover (tractor unit), prime mover was the draught horse. They became popular in industrialised countries from around 1850, when the first self-propelled portable steam engines for agricultural use were developed. Production continued well into the early part of the 20th century, when competition from internal combustion engine-powered ...
