Midland Railway 483 Class
The Midland Railway 483 Class 4-4-0 was a class of steam locomotive designed by Henry Fowler for passenger work on the Midland Railway. The class were nominally "rebuilds" of various earlier classes designed by Samuel W. Johnson, although the '483' class engines were, unquestionably, 'accountancy rebuilds' (effectively new locos 'disguised' to gain routine expenditure approval from the board). This design formed the basis for the later LMS Class 2P 4-4-0. Construction of the first batch of this class was authorised by Midland Railway Order O/3942 dated 21 June 1911: 'Please put your work in hand in connection with rebuilding engines 483–522 with new frames, new cylinders and G7 boilers fitted with Schmidt's superheaters.' Apart from the savings made by using the parts that were salvaged from the old engines, there was an added benefit in referring to them as rebuilt since the royalties due to the superheater company were lower for modified locomotives than for new ones.

Samuel Waite Johnson
Samuel Waite Johnson (14 October 1831 – 14 January 1912) was an English railway engineer, and was Chief Mechanical Engineer (CME) of the Midland Railway from 1873 to 1903. He was born in Bramley, Yorkshire and educated at Leeds Grammar School. Career Johnson learned to become an engineer at the locomotive builders E.B.Wilson and Company. In 1859 Johnson became Acting Locomotive Superintendent at the Manchester, Sheffield and Lincolnshire Railway. In 1864 he was appointed Locomotive Superintendent of the Edinburgh and Glasgow Railway. In 1866, after only two years in Scotland he replaced Robert Sinclair of the Great Eastern Railway (GER) at Stratford Works. There he stayed for seven years until moving to the Midland Railway (MR) at Derby, where he stayed until his retirement in 1904. At the time of appointment to the Midland Railway on 1 July 1873, he was paid a salary of £2,000 per year (), rising to £3,500 in 1896 () where it remained until his retirement on 31 ...

Piston Valve (steam Engine)
Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power. The valve consists of two piston heads on a common spindle moving inside a steam chest, which is essentially a mini-cylinder located either above or below the main cylinders of the locomotive. Overview In the 19th century, steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * It is difficult to lubricate slide valves adequately in the presence of superheated steam * With piston valves, the steam passages can be made shorter. This, particularly following the work of André Chapelon, reduces resistance to the flow of steam and improves eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Locomotives Introduced In 1882
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 faciliti ...

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 pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slide Valve
The slide valve is a rectilinear valve used to control the admission of steam into and emission of exhaust from the cylinder of a steam engine. Use In the 19th century, most steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * With piston valves, the steam passages can be made shorter. This reduces resistance to the flow of steam and improves efficiency. * It is difficult to lubricate slide valves adequately in the presence of superheated steam. Murdoch's D slide valve The D slide valve, or more specifically Long D slide valve, is a form of slide valve, invented by William Murdoch and patented in 1799. It is named after the hollow central D-sectioned piston. This valve worked by "connecting the upper and lower valves so as to be worked by one rod or spindle, and in maki ...

4-4-0
4-4-0 is a locomotive type with a classification that uses the Whyte notation for the classification of steam locomotives by wheel arrangement and represents the arrangement: four leading wheels on two axles (usually in a leading bogie), four powered and coupled driving wheels on two axles, and a lack of trailing wheels. Due to the large number of the type that were produced and used in the United States, the 4-4-0 is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced.White, John H., Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York: Dover Publications, pp. 46-. Almost every major railroad that operated in North America in the first half of the 19th century owned and operated locomotives of this type. The first use of the name ''American'' to describe locomotives of this wheel arrangement was made by ''Railroad Gazette'' in April 1872. Prior to ...

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 motion'' in the United Kingdom and'' V-hook motion'' in the 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 only gave fixed valve events. In 1841, two employees of Robert Stephenson and Company, draughtsman William Howe and patte ...
