GWR 9400 Class
The Great Western Railway (GWR) 9400 Class is a class of 0-6-0 pannier tank steam locomotive, used for shunting and banking duties. The first ten 9400s were the last steam engines built by the GWR. After nationalisation in 1948, another 200 were built by private contractors for British Railways (BR). Most had very short working lives as the duties for which they were designed disappeared through changes in working practices or were taken over by diesel locomotives. Two locomotives survived into preservation, with the oldest of the class, 9400 as part of the National Collection. Design The 9400 class was the final development in a long lineage of tank locomotives that can be directly traced to the 645 Class of 1872. Over the decades details altered, the most significant being the adoption of Belpaire fireboxes necessitating pannier tanks. The 9400 resembled a pannier tank version of the 2251 class, and indeed shared the same boiler and cylinders as the 2251, but was in fac ...

Frederick Hawksworth
Frederick William Hawksworth (10 February 1884 – 13 July 1976), was the last Chief Mechanical Engineer of the Great Western Railway (Great Britain) (GWR). Early career Hawksworth spent his entire career at the Swindon Works of the GWR. He joined the company as an apprentice in 1898, aged 15, becoming an apprentice draughtsman in 1905 under George Jackson Churchward. Hawksworth was one of Churchward's "Bright Young Men", and was involved in his revolutionary designs including the general arrangement drawings for "The Great Bear". Following Churchward's retirement in December 1921, Hawksworth was appointed Chief Draughtsman to his successor Charles Collett where he co-ordinated the work on the King Class. In 1932 he was appointed Assistant, to the Chief Mechanical Engineer, following the departure of William Stanier to the London Midland and Scottish Railway. Soon afterwards he became Principal Assistant. However, having been at the forefront of steam locomotive developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too qu ...

Dunstall Park Station, With Up Goods Including A Dead Engine Geograph-2572669-by-Ben-Brooksbank
Dunstall is a small village and civil parish in the borough of East Staffordshire, Staffordshire, England. It lies between Burton upon Trent and Barton-under-Needwood. The population of the parish at the 2001 census was 215, decreasing to 209 at the 2011 Census. History of Dunstall Population The population of Dunstall has fluctuated in the past, but not very dramatically. In 1801 it was reported that the population was 177, in 1817 it was 157, in 1821 it was 184 and in 1831 it was 204 showing that the population has always fluctuated in this once registered township. In 1870–72, John Marius Wilson described Dunstall as "a town-ship chapelry" with a population of just 240 residents living in 51 houses however while the population has decreased the number of houses has gradually increased with 1950 seeing more than 90 houses and the 2001 census reporting a population of 215.

Hunslet Engine Company
The Hunslet Engine Company is a locomotive-building company, founded in 1864 in Hunslet, England. It manufactured steam locomotives for over 100 years and currently manufactures diesel shunting locomotives. The company is part of Ed Murray & Sons. History The early years 1864–1901 The company was founded in 1864 at Jack Lane in Hunslet by John Towlerton Leather, a civil engineering contractor, who appointed James Campbell (son of Alexander Campbell, a Leeds engineer) as his works manager. The first engine was completed in 1865. It was ''Linden'', a standard gauge delivered to Brassey and Ballard, a railway civil engineering contractor as were several of the firm's early customers. Other customers included collieries. This basic standard gauge shunting and short haul "industrial" engine was to be the main-stay of Hunslet production for many years. In 1871, James Campbell bought the company for £25,000 (payable in five instalments over two years) and the firm remained ...

Hudswell Clarke
Hudswell, Clarke and Company Limited was an engineering and locomotive building company in Jack Lane, Hunslet, Leeds, West Yorkshire, England. History The company was founded as Hudswell and Clarke in 1860. In 1870 the name was changed to Hudswell, Clarke and Rodgers. There was another change in 1881 to Hudswell, Clarke and Company. The firm became a limited company in 1899. In 1862, soon after the company had been formed, they were given the initial design work on William Hamond Bartholomew's compartment boats for the Aire and Calder Navigation. The choice of the company may have been influenced by the fact that Bartholomew, the chief engineer for the Navigation, and William Clayton, one of the founders of Hudswell and Clarke, both lived on Spencer Place in Leeds. They produced at least one of the prototype Tom Pudding compartments, but did not get the main contract for their production once the design work had been done. As steam locomotive builders, like many of the sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, of ...

Fire-tube Boiler
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or " haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume. The general construction is as a tank of water penetrated by tubes that carry the hot flue gases from the fire. The tank is usually cylindrical for the most part—being the strongest practical shape for a pressurized container—and this cylindrical tank may be either horizontal or v ...

GWR 2251 Class
The Great Western Railway (GWR) 2251 Class or Collett Goods Class was a class of 0-6-0 steam tender locomotives designed for medium-powered freight. They were introduced in 1930 as a replacement for the earlier Dean Goods 0-6-0s and were built up to 1948. Overview In many ways, the 2251s were modernised Dean Goods, sharing the main dimensions, but having more modern features such as taper boilers and full cabs. Increases in both boiler pressure and heating surface gave a useful increase in power at the expense of weight that restricted permitted routes. Numbers 2211–2230, built in 1940 did not have side windows. Designed by Charles Collett for medium freight and passenger duties they had driving wheels. Carrying a maximum of of water to fuel a boiler operating at they developed of tractive effort. They could be found operating on most parts of the former GWR system. These were the first GWR 0-6-0 to use the standard number 10 boiler as later fitted to the 94xx, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belpaire Firebox
The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today it generally refers to the shape of the outer shell of the firebox which is approximately flat at the top and square in cross-section, indicated by the longitudinal ridges on the top sides. However, it is the similar square cross-section inner firebox which provides the main advantages of this design i.e. it has a greater surface area at the top of the firebox where the heat is greatest, improving heat transfer and steam production, compared with a round-top shape. The flat firebox top would make supporting it against pressure more difficult (e.g. by means of girders, or stays) compared to a round-top. However, the use of a similarly shaped square outer boiler shell allows simpler perpendicular stays to be used between the shells. The Belpaire outer firebox is, nevertheless, more complicated and expensive to manufacture than a round-top version. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GWR 645 Class
The GWR 645 Class was a class of designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six were constructed between 1872-3, of which three were built for the South Wales Mineral Railway (SWMR), two for the Carmarthen and Cardigan Railway (C&CR) and the remainder for the GWR. In essence, they were saddle tank versions of his GWR 633 Class of 1871. From 1878, a further 72 of the class, partially enlarged, were added in the 1501 numbering sequence. Unlike the originals, the "1501"s had full-length saddle tanks from the start. Construction The whole class was delivered in nine lots, as follows: * 645-655, plus one (Lot O, 1872) * 656, 757-763, plus four (Lot P, 1872-3) * 764-775 (Lot Q, 1873) * 1501-1512 (Lot A2, 1878) * 1513-1524 (Lot B2, 1878-9) * 1525-1536 (Lot D2, 1879) * 1537-1548 (Lot E2, 1879–80) * 1549-60 (Lot F2, 1880) * 1801-1812 (Lot G2, 1881) Three of the un-numbered engines plus No. 767 were sold to the ...
