LSWR D15 Class
The LSWR D15 class 4-4-0 was the last steam locomotive design by Dugald Drummond for the London and South Western Railway in 1912. By 1912, Dugald Drummond had built several classes of unsuccessful 4-6-0 express passenger locomotives. The result of these failures was that when he designed what was to be his last class in 1911, a new 4-4-0 design emerged from Eastleigh Works in February 1912, with what was to be the first of his D15 class. Technical details Boiler In line with the typical Drummond layout, the D15s had a short smokebox with wing plates. The boiler was based on that fitted to the 1905 rebuild of his first double-single, T7 class number 720 of 1897; and had a long firebox with a sloping grate. This resulted in the boiler being pitched higher than usual to allow clearance over the trailing axle. Water feed An exhaust steam feedwater heater was provided and the boiler fed by duplex pumps located on the frames, between the coupled wheels. Tenders The class was i ...

Feedwater Heater
A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system.Fundamentals of Steam Power by Kenneth Weston, This reduces plant operating costs and also helps to avoid to the boiler metal when the feedwater is introduced back into the steam cycle.

Water
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity. Some iron and steel-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LSWR T14 Class
The London and South Western Railway (LSWR, sometimes written L&SWR) was a railway company in England from 1838 to 1922. Originating as the London and Southampton Railway, its network extended to Dorchester and Weymouth, to Salisbury, Exeter and Plymouth, and to Padstow, Ilfracombe and Bude. It developed a network of routes in Hampshire, Surrey and Berkshire, including Portsmouth and Reading. The LSWR became famous for its express passenger trains to Bournemouth and Weymouth, and to Devon and Cornwall. Nearer London it developed a dense suburban network and was pioneering in the introduction of a widespread suburban electrified passenger network. It was the prime mover of the development of Southampton Docks, which became an important ocean terminal as well as a harbour for cross channel services and for Isle of Wight ferries. Although the LSWR's area of influence was not the home of large-scale heavy industry, the transport of goods and mineral traffic was a major activity, ...

Bournemouth
Bournemouth ( ) is a coastal resort town in the Bournemouth, Christchurch and Poole unitary authority area, in the ceremonial county of Dorset, England. At the 2021 census, the built-up area had a population of 196,455, making it the largest town in Dorset. Previously an uninhabited heathland, visited only by occasional fishermen and smugglers, a health resort was founded in the area by Lewis Tregonwell in 1810. After the Ringwood, Christchurch and Bournemouth Railway opened in 1870, it grew into an important resort town which attracts over five million visitors annually to the town's beaches and nightlife. Financial services provide significant employment. Part of Hampshire since before the Domesday Book, Bournemouth was assigned to Dorset under the Local Government Act 1972 in 1974. Bournemouth Borough Council became a unitary authority in 1997 and was replaced by Bournemouth, Christchurch and Poole Council in 2019; the current unitary authority also covers Poole, Chr ...

Railways Act 1921
The Railways Act 1921 ( 11 & 12 Geo. 5. c. 55), also known as the Grouping Act, was an act of Parliament enacted by the British government, and was intended to stem the losses being made by many of the country's 120 railway companies, by "grouping" them into four large companies, dubbed the " Big Four". The system of the "Big Four" lasted until the nationalization of the railways in 1947. During World War I, the British government took control, although not ownership, of British railways. The intention was to reduce inefficient internal competition between railway companies, and retain some of the benefits which the country had derived from a government-controlled railway system during the war. The provisions of the act took effect from the start of 1923. History The British railway system had been built up by more than a hundred railway companies, large and small, and often, particularly locally, in competition with each other. The parallel railways of the East Midlands, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Railway (Great Britain)
The Southern Railway (SR), sometimes shortened to 'Southern', was a British railway company established in the 1923 Grouping. It linked London with the Channel ports, South West England, South coast resorts and Kent. The railway was formed by the amalgamation of several smaller railway companies, the largest of which were the London and South Western Railway (LSWR), the London, Brighton and South Coast Railway (LB&SCR) and the South Eastern and Chatham Railway (SE&CR).Bonavia (1987) pp. 26–28 The construction of what was to become the Southern Railway began in 1838 with the opening of the London and Southampton Railway, which was renamed the London & South Western Railway. The railway was noted for its astute use of public relations and a coherent management structure headed by Sir Herbert Walker. At , the Southern Railway was the smallest of the "Big Four" railway companies, the only one to operate entirely in England, and, unlike the others, the majority of its reven ...

Chief Mechanical Engineer
Chief mechanical engineer and locomotive superintendent are titles applied by British, Australian, and New Zealand railway companies to the person ultimately responsible to the board of the company for the building and maintaining of the locomotives and rolling stock. In Britain, the post of ''locomotive superintendent'' was introduced in the late 1830s, and ''chief mechanical engineer'' in 1886. Emerging professional roles In the early Victorian era, projected canal or railway schemes were prepared by groups of promoters who hired specialists such as civil engineers, surveyors, architects or contractors to survey a route; and this resulted in the issue of a prospectus setting out their proposals. Provided that adequate capital could be raised from potential investors, agreements obtained from the landowners along the proposed route and, in Britain, an Act of Parliament obtained (different terminology is used in other countries), then construction might begin either by a new c ...

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, in some 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 the 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, in the path of the hot flue gases, usually ahead of an economizer. A convection superheater is also called a primary superheater. * A separately fired superheater is a superheater that is placed outside the main boiler and has its own separate combustion system. This superheater design incorporates additional burners i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
