GWR 2721 Class
The GWR 2721 Class was a class of steam locomotives. They were designed by William Dean and built at the Swindon Works of the Great Western Railway between 1897 and 1901. Design They were not a new design, being a straightforward development of the 120-strong 1854 Class dating back to 1890. This lineage had begun with George Armstrong's 645 Class in 1872 and continued via the 1813 Class (in 1882), the 1854 Class, and finally ended in 1948 with the GWR 9400 Class. The differences over 76 years were undeniably a gradual evolution, with increases in boiler pressure and heating surface the more important, enclosed cabs and larger bunkers cosmetic but functional. The biggest change was the fitting of a Belpaire firebox necessitating a pair of pannier tanks, as the square-topped firebox is not compatible with a curved saddle tank. Highlighting the gradual nature of the changes are the subtle differences between the 1854 and 2721 classes, confined to a small increase in wheel s ...

William Dean (engineer)
William Dean (8 January 1840 – 24 September 1905) was an English railway engineer. He was the second son of Henry Dean, who was the manager of the Hawes Soap Factory in New Cross, London. William was educated at the Haberdashers' Company School. He became the Chief Locomotive Engineer for the Great Western Railway from 1877, when he succeeded Joseph Armstrong (engineer), Joseph Armstrong. He retired from the post in 1902 and was replaced by George Jackson Churchward. He designed famous steam locomotive classes such as the GWR 3252 Class, Duke Class, the GWR 3300 Class, Bulldog Class and the long-lived GWR 2301 Class, 2301 Class. Apprenticeship He was apprenticed at the age of fifteen to Joseph Armstrong at the Great Western Railway's Wolverhampton Wolverhampton railway works, Stafford Road Works. During his eight-year apprenticeship he attended Wolverhampton Working Men's College in the evening, excelling in mathematics and engineering. Upon completion of his apprentice years ...

GWR 5700 Class
The GWR 5700 Class, or 57xx class, is a class of 0-6-0 pannier tank steam locomotive, built by the Great Western Railway (GWR) and British Railways (BR) between 1929 and 1950. With 863 built, they were the most prolific class of the GWR, and one of the most numerous classes of British steam locomotive. Although officially designated by GWR as "light goods and shunting engines", they were also used for passenger working on branch, suburban, and shorter mainline journeys. They were distributed across most of the GWR network and, after nationalisation of the railways in 1948, across the Western Region of British Railways, and also other regions. The 5700s were not as large as the GWR Castles and Kings, but became just as much of an icon of the GWR due to their iconic design and quantity. As a result of the 1955 Modernisation Plan, the 5700 Class was withdrawn from BR service between 1956 and 1966. Nineteen withdrawn locomotives were sold to London Transport and industry, ...

Railway Locomotives Introduced In 1897
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GWR 0-6-0PT
The GWR 0-6-0PT (Pannier Tank), is a type of steam locomotive built by the British Great Western Railway with the water tanks carried on both sides of the boiler, in the manner of panniers. They were used for local, suburban and branch line passenger and goods traffic, for shunting duties, and as banker engines on inclines. The early examples, such as the 1901 and 2021 classes, were rebuilt from saddle or side tanks when the locos received a Belpaire firebox – this type of firebox has a square top and is incompatible with a curved saddle tank. This process mostly took place during the tenure at Swindon Works of George Jackson Churchward. Only a very small number of saddle tank locomotives escaped rebuilding as panniers, notably the 1361 Class built new under Churchward in 1910, by which date a few of the 1813 Class had already been rebuilt as pannier tanks. Classification The GWR pannier tank locomotives were classified as follows: Small engines (wheelbase under 15' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OO Gauge
OO gauge or OO scale (also, 00 gauge and 00 scale) is the most popular standard-gauge model railway standard in the United Kingdom, outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards (4 mm to 1 foot, or 1:76.2), and the only one to be marketed by major manufacturers. The OO track gauge of (same as H0 scale) corresponds to prototypical gauge of , rather than standard gauge. However, since the 1960s, other gauges in the same scale have arisen—18.2 mm (EM) and 18.83 mm (Scalefour)—to reflect the desire of some modellers for greater scale accuracy. Origin Double-0 scale model railways were launched by Bing in 1921 as "The Table Railway", running on track and scaled at 4 mm-to-the-foot. In 1922, the first models of British prototypes appeared. Initially all locomotives were powered by clockwork, but the first electric power appeared in autumn 1923. OO describes models with a scale of 4 mm = 1 foot (1:76) runnin ...

Hornby Railways
Hornby Railways is a British rail transport modelling, model railways manufacturing company. Its roots date back to 1901 in Liverpool, when founder Frank Hornby received a patent for his Meccano construction toy. The first clockwork train was produced in 1920. In 1938, Hornby launched its first 00 gauge train. In 1964, Hornby and Meccano were bought by their competitor, Tri-ang, and sold when Tri-ang went into receivership. Hornby Railways became independent again in the 1980s, and became listed on the London Stock Exchange, but due to financial troubles reported in June 2017, became majority owned by British turnaround specialist Phoenix Asset Management. Apart from trains, Hornby also commercialises model cars and other vehicles through its brands Bassett-Lowke, Corgi Toys, Corgi, Jouef, Lima (models), Lima, Pocher, and Scalextric. History Early history: 1920–1938 Hornby was at first a tradename for the railway productions of Meccano Ltd and based around Liverpool. U ...

GWR 2800 Class
The Great Western Railway (GWR) 2800 Class is a class of Churchward-designed 2-8-0 steam locomotive. History The class was designed by George Jackson Churchward for heavy freight work. They were the first 2-8-0 locomotive class in Great Britain. The prototype, originally numbered 97 but later renumbered 2800, appeared in 1903. Construction of the production series commenced in 1905 and continued until 1919. The 2884 Class which appeared in 1938–1942 was developed from the 2800 class and is sometimes classified with it. Prototype No. 97 was originally outshopped in lined black livery and undertook two years of trials before the type went into production. Initial results suggested that only the front end needed further development and where the boiler of No. 97 was parallel for the first four segments, the production series had the familiar taper boiler. Initially the boiler pressure of the 2-8-0 was set at with diameter cylinders. Tractive effort started out at but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Railways
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997. It was formed from the nationalisation of the Big Four British railway companies, and was privatised in stages between 1994 and 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. The period of nationalisation saw sweeping changes in the railway. A process of dieselisation and electrification took place, and by 1968 steam locomotives had been entirely replaced by diesel and electric traction, except for the Vale of Rheidol Railway (a narrow-gauge tourist line). Passengers replaced freight as the main source of business, and one-third of the network was closed by the Beeching cuts of the 1960s in an effort to reduce rail subsidies. On privatis ...

Coil Spring
A selection of conical coil springs The most common type of spring is the coil spring, which is made out of a long piece of metal that is wound around itself. Coil springs were in use in Roman times, evidence of this can be found in bronze Fibulae - the clasps worn by Roman soldiers among others. These are quite commonly found in Roman archeological digs. Coil springs can be either compression springs, tension springs or torsion springs, depending on how they are wound. A coil spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. They are commonly used in mattresses, automotive suspensions, and residential plumbing. Coil springs come in a variety of sizes and shapes and can be used for a variety of applications. Small coil springs are often us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
