LNER P2 Class 2007 Prince Of Wales
LNER Class P2 No. 2007 ''Prince of Wales'' is a 2-8-2 "Mikado" steam locomotive being built at Darlington Locomotive Works, England, and managed by the A1 Steam Locomotive Trust. It will be the seventh member of its class and the only P2 in existence; the original six were built between 1934 and 1936 for the London and North Eastern Railway (LNER) to a design by Nigel Gresley, and employed to haul heavy passenger trains on the Edinburgh–Dundee line, Edinburgh to Aberdeen line. The P2s were declared Britain's most powerful express passenger engines, although none were preserved. The A1 Trust announced the project in 2013, following the completion and success of its first new build locomotive, LNER Peppercorn Class A1 No. 60163 ''LNER Peppercorn Class A1 60163 Tornado, Tornado'', in 2008. Construction on ''Prince of Wales'' began in 2014 with its design based on P2 No. 2001 ''Cock o' the North'' with some modifications to improve maintenance, address historic problems, and comp ...

Nigel Gresley
Sir Herbert Nigel Gresley (19 June 1876 – 5 April 1941) was a British railway engineer. He was one of Britain's most famous steam locomotive engineers, who rose to become Chief Mechanical Engineer (CME) of the London and North Eastern Railway (LNER). He was the designer of some of the most famous steam locomotives in Britain, including the GNR Class A1, LNER Class A1 and LNER Class A4 Whyte notation, 4-6-2 4-6-2, Pacific engines. An A1 Pacific, ''LNER Class A3 4472 Flying Scotsman, Flying Scotsman'', was the first steam locomotive officially recorded over 100 mph in passenger service, and an A4, No. 4468 ''LNER Class A4 4468 Mallard, Mallard'', still holds the record for being the fastest steam locomotive in the world (126 mph). Gresley's engines were considered elegant, both aesthetically and mechanically. His invention of a three-cylinder design with only two sets of Walschaerts valve gear, the Gresley conjugated valve gear, produced smooth running and power at ...

Loading Gauge
A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and loading gauges may vary across a network, even if the track gauge is uniform. The term loading gauge can also be applied to the maximum size of road vehicles in relation to tunnels, overpasses and bridges, and doors into automobile repair shops, bus garages, filling stations, residential garages, multi-storey car parks and warehouses. A related but separate gauge is the structure gauge, which sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. The difference between these two gauges is called the clearance. The specified amount of clearance makes allowance for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder
A cylinder () has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base. A cylinder may also be defined as an infinite curvilinear surface in various modern branches of geometry and topology. The shift in the basic meaning—solid versus surface (as in a solid ball versus sphere surface)—has created some ambiguity with terminology. The two concepts may be distinguished by referring to solid cylinders and cylindrical surfaces. In the literature the unadorned term "cylinder" could refer to either of these or to an even more specialized object, the '' right circular cylinder''. Types The definitions and results in this section are taken from the 1913 text ''Plane and Solid Geometry'' by George A. Wentworth and David Eugene Smith . A ' is a surface consisting of all the points on all the lines which are parallel to a given line and which pass through a ...

Resonate Group
Resonate Group Limited is a British software, technology and services company. Prior to September 2016, it was called ''DeltaRail Group Limited''. The company was formed from the Rail business of AEA Technology plc which was acquired as part of a secondary private equity portfolio sale to Vision Capital in 2006. On 21 January 2015, the four Executive Directors of the company acquired the business out of private equity ownership. The ''Resonate Group'' brand was adopted in September 2016. The company has UK offices in Derby (head office) and London. History The origins of Resonate Group can be traced back to 1998 and the formation of AEA Technology plc's rail business following the acquisition of British Rail Research from the British Railways Board, which was amalgamated with several other engineering software organisations. It provided software, technology and services in three core areas; signalling control software, operational software and asset management products. Res ...

Finite Element Analysis
Finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical models, mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. Computers are usually used to perform the calculations required. With high-speed supercomputers, better solutions can be achieved and are often required to solve the largest and most complex problems. FEM is a general numerical analysis, numerical method for solving partial differential equations in two- or three-space variables (i.e., some boundary value problems). There are also studies about using FEM to solve high-dimensional problems. To solve a problem, FEM subdivides a large system into smaller, simpler parts called finite elements. This is achieved by a particular space discretization in the space dimensions, which is implemented by the constructio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal Fatigue
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striation (fatigue), striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid ...

Tender (rail)
A tender is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board are called '' tank locomotives'' or ''tank engines''. A corridor tender is a locomotive tender with a passageway to one side, allowing crew changes on the fly. A brake tender is a tender that is heavy and used (primarily) to provide greater braking efficiency. General functions The largest steam locomotives are semi-permanently coupled by a drawbar to a tender that carries the water and fuel. The fuel source used depends on what is economically available locally. In the UK and parts of Europe, a plentiful supply of coal made this the obvious ...

Streamliner
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor " bullet trains". Less commonly, the term is applied to fully faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels. Trains Before World War II Europe * Germany, 1930: The first high-speed streamliner in Germany was the '' Schienenzeppelin'', an experimental propeller-driven single car, built in 1930. On 21 June 1931, the car set a speed record of on a run between Berlin and Hamburg. In 1932 the propeller was removed and a h ...

Valve Gear
The valve gear of a steam engine is the mechanism that operates the inlet and exhaust valves to admit steam into the cylinder and allow exhaust steam to escape, respectively, at the correct points in the cycle. It can also serve as a reversing gear. It is sometimes referred to as the "motion". Purpose In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure, minus transmission losses, against the piston throughout the stroke) while peak efficiency is achieved by only having the inlet valve open for a short time and then letting the steam expand in the cylinder (expansive working). The point at which steam stops being admitted to the cylinder is known as the '' cutoff'', and the optimal posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppet Valve
A poppet valve (also sometimes called mushroom valve) is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. Etymology The word poppet shares etymology with "puppet": it is from the Middle English ''popet'' ("youth" or "doll"), from Middle French ''poupette'', whic ...

Hugo Lentz
Hugo Lentz (1859–1944) was an Austrian mechanical engineer, born in Cape Colony. He was the inventor of many award-winning improvements to the steam engine. The correct spelling of his name is Lenz but it has been Anglicised to Lentz in English-speaking countries. Life and career Lentz was born on 21 July 1859 in Cape Colony. When he was six years old, his father died and the family returned to relatives in Germany. He became an engineer in the Prussian Navy. In 1888, Lentz founded his own machine factory in Vienna. At an exposition in honour of Alessandro Volta in Como in 1899, his first steam engine won the first prize. At the Exposition Universelle (1900) in Paris, it won the ''Grand Prix'' while Lentz himself was awarded the gold medal.
