LSWR L11 Class
The London and South Western Railway L11 class was a class of 4-4-0 steam locomotives designed for Mixed-traffic locomotive, mixed traffic work. They were introduced in 1903 in rail transport, 1903 and were nicknamed "Large Hoppers". As with most other Drummond productions, the locomotive had two inside cylinders and Stephenson link valve gear. Background The L11 class was one of a number of designs by Dugald Drummond incorporating a large proportion of standard parts that could be interchanged with other classes of locomotive. The boiler was interchangeable with the LSWR T9 Class, T9 class, and likewise was equipped with water tubes fitted across the firebox (steam engine), firebox combustion space, with the aim of increasing heating surface whilst facilitating water circulation; this device however also increased maintenance costs and was soon removed by Drummond's successor, Robert Urie. Later history The L11 class was never equipped with a superheater as was applied to ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dugald Drummond
Dugald Drummond (1 January 1840 – 8 November 1912) was a Scottish steam locomotive engineer. He had a career with the North British Railway, LB&SCR, Caledonian Railway and London and South Western Railway. He was the older brother of the engineer Peter Drummond, who often followed Dugald's ideas in his own work. He was a major locomotive designer and builder and many of his London and South Western Railway engines continued in main line service with the Southern Railway to enter British Railways service in 1947. Career Drummond was born in Ardrossan, Ayrshire on 1 January 1840. His father was permanent way inspector for the Bowling Railway. Drummond was apprenticed to Forest & Barr of Glasgow gaining further experience on the Dumbartonshire and Caledonian Railways. He was in charge of the boiler shop at the Canada Works, Birkenhead of Thomas Brassey before moving to the Edinburgh and Glasgow Railway's Cowlairs railway works in 1864 under Samuel Waite Johnson. He beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Railway Locomotives Introduced In 1903
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London And South Western Railway Locomotives
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as ''Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942 Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters ''The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher. Each year it published books covering subjects such as military and civil aviation, naval and maritime topics, buses, trams, trolleybuses and steam railways, including hi ...

LSWR T9 Class
The London and South Western Railway T9 class was a class of 66 4-4-0 steam locomotive designed for express passenger work by Dugald Drummond and introduced to services on the LSWR in 1899. One example has been preserved after British Railways ownership. They were given the nickname of "Greyhounds" due to their speed, up to , and reliability. Background Intended for express passenger work in South-West England, 66 were eventually built and saw several improvements throughout their service careers. The class operated until 1963 when the last example, No 30120, was withdrawn. 30120 was preserved by the National Railway Museum and is currently on loan to the Swanage Railway. Construction history The design spawned from the relative failure of Drummond's C8 class of 1898, utilising many lessons learned from this design.Bradley (1986). A larger boiler was implemented, and such confidence was placed in Drummond's design that an order of 50 locomotives was placed straight of ...

LSWR C8 Class
The LSWR C8 class was the first class of 4-4-0 express steam locomotives designed by Dugald Drummond for the London and South Western Railway and introduced in 1898. According to Marshall they "were of orthodox design, very much like engines which Drummond had put on the Caledonian". Marshall gives few other details, except to say that they were numbered 290-299 and had 18 in x 26 in cylinders. H.C. Casserley states that they were very similar to the Caledonian Railway 66 class. They used a similar boiler to the Drummond M7 0-4-4T and 700 class 0-6-0 engines built for the LSWR. They originally used a similar tender to the 700 class, but these were later replaced with Drummond's eight-wheeled bogie "watercart" tenders. They were not particularly good steamers, due to their firebox being too small. None were ever superheated, and they were withdrawn after service lives of 35 to40 years. In November 1898, No. 291 worked a train carrying the Grand Duke and Duchess Serge of Russia f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LSWR K10 Class
The London and South Western Railway K10 Class was a class of 40 4-4-0 steam locomotives designed for mixed traffic work. They were introduced on the London and South Western Railway in 1901 and 1902 to the design of Dugald Drummond, where they earned the nickname "Small Hoppers". Background In order to satisfy a pressing requirement for mixed-traffic locomotives, Drummond adopted the solution of a small-wheeled 4-4-0 he had previously employed on the Caledonian Railway. The resulting K10 had the same diameter coupled wheels as the M7 and the boiler was interchangeable with the M7, 700 and C8 classes Construction history Forty of the class were subsequently outshopped from the LSWR's Nine Elms Locomotive Works. They were generally paired with a 6-wheel tender because of their intended short journey lengths, which included local stopping trains and medium-level freight haulage, but as with the later L11 class, some could occasionally be seen with a "watercart" tender f ...

30166 On Shed
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in ...

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] |
