Beyer-Garratt
A Garratt (often referred to as a Beyer Garratt) is a type of steam locomotive invented by British engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage. Articulation permits locomotives to negotiate curves that might restrict large rigid-framed locomotives. The design also provides more driving wheels per unit of locomotive weight, permitting operation on lightly engineered track. Garratt locomotives produced as much as twice the power output of the largest conventional locomotives of railways that introduced them, reducing the need for multiple locomotives and crews. Advantages of the Garratt concept The principal benefit of the Garratt design is that the boil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beyer, Peacock & Company
Beyer, Peacock and Company was an English railway locomotive manufacturer with a factory in Openshaw, Manchester. Founded by Charles Beyer, Richard Peacock and Henry Robertson, it traded from 1854 until 1966. The company exported locomotives, and machine tools to service them, throughout the world. Founders German-born Charles Beyer had undertaken engineering training related to cotton milling in Dresden before moving to England in 1831 aged 21. He secured employment as a draughtsman at Sharp, Roberts and Company's Atlas works in central Manchester, which manufactured cotton mill machinery and had just started building locomotives for the Liverpool and Manchester Railway. There he was mentored by head engineer and prolific inventor of cotton mill machinery, Richard Roberts. By the time he resigned 22 years later he was well established as the company's head engineer; he had been involved in producing more than 600 locomotives. Richard Peacock had been chief engineer of the Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Herbert William Garratt
Herbert William Garratt (8 June 1864 – 25 September 1913) was an English mechanical engineer and the inventor of the Garratt system of articulated locomotives. Garratt began his engineering career by serving an apprenticeship under John Carter Park, then locomotive superintendent of the North London Railway, from 1879 to 1882 at the North London Railway's Bow works. He gained further experience at Doxford's marine engineering works in Sunderland and later as an inspector for Sir Charles Fox and Sir Alexander Rendel. Garratt joined the Argentine Central Railway in 1889, where he became Locomotive Superintendent in 1892, and between 1900 and 1906 he worked for railways in Cuba, Lagos and Lima (Peru). In 1902, Garratt was elected to membership of the Institute of Mechanical Engineers. He returned to England in 1906, taking on a role inspecting locomotives built for the New South Wales Government Railways by British manufacturers. Design and impact of Garratt locomotive ...

Golwé Locomotive
Golwé locomotive for the Ivory Coast The Golwé was a type of articulated steam locomotive manufactured in Belgium for use in French West African colonies. Design The design was patented in 1924, as the work of G. Goldschmidt and A. Weber, managing director and chief engineer of the in Belgium. A single rigid frame ran the length of the locomotive and carried the boiler, fuel and water. The front engine unit swivelled under the boiler and smokestack, in a similar manner to a Meyer and looking somewhat like a Mallet; in contrast a Garratt had its front bogie in front of the boiler. The rear engine unit was placed underneath the tender, in a manner similar to a Garratt; however, while a Garratt carried both coal and water directly on the rear bogie, the Golwé had its fuel bunker mounted on the central frame. The water tank was mounted directly on the rear steam bogie and embraced the fuel bunker and rear end of the main frame. The rear bogie cylinders were placed under the cab, ...

Compound Locomotive
A compound locomotive is a steam locomotive which is powered by a compound engine, a type of steam engine where steam is expanded in two or more stages. The locomotive was only one application of compounding. Two and three stages were used in ships, for example. Compounding became popular for railway locomotives from the early 1880s and by the 1890s were becoming common. Large numbers were constructed, mostly two- and four-cylinder compounds, in France, Germany, Austria, Hungary, and the United States. It declined in popularity due to maintenance issues and because superheating provided similar efficiencies at lower cost. Nonetheless, compound Mallets were built by the Norfolk and Western Railway right up to 1952. Introduction In the usual arrangement for a compound engine the steam is first expanded in one or two high-pressure ''(HP)'' cylinders, then having given up some heat and lost some pressure, it exhausts into a larger-volume low-pressure ''(LP)'' cylinder, (or two, - or ...

Tasmanian Government Railways K Class
The Tasmanian Government Railways K class was a class of 0-4-0+0-4-0 Garratt articulated steam locomotives operated by the Tasmanian Government Railways from 1909 – the first Garratt locomotives built. Overview Although considered the first Garratt locomotives, they did in fact differ in two important details from Herbert Garratt's original concept. First: they are compound locomotives, with two high-pressure cylinders on the rear engine, and a pipe leading to two larger low-pressure cylinders on the front engine; second: both sets of cylinders were placed facing each other inside their engine units, rather than facing out as in all other Garratts. This was a problem on the rare warm days on the West Coast Range in Tasmania, as one pair of cylinders was under the cab, making the cab uncomfortably hot. The North East Dundas Tramway on which they worked traversed some of the most rugged terrain in the world served by a railway at the time. It featured long stretches of 1-in- ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber.

Kitson & Company
Kitson and Company was a locomotive manufacturer based in Hunslet, Leeds, West Yorkshire, England. Early history The company was started in 1835 by James Kitson at the Airedale Foundry, off Pearson Street, Hunslet, with Charles Todd as a partner. Todd had been apprenticed to Matthew Murray at the Round Foundry in Holbeck, Leeds. Initially, the firm made parts for other builders, until it was joined in 1838 by David Laird, a wealthy farmer who was looking for investments, and the company became Todd, Kitson and Laird. That year saw the production of the company's first complete locomotives, either for the North Midland or the Liverpool and Manchester Railway. However, Todd left almost immediately to form Shepherd and Todd, and the company was known variously as Kitson and Laird or Laird and Kitson. The order for six engines by the Liverpool and Manchester began with ''Lion'', which still exists. Around 1858, it was withdrawn from service and sold to the Mersey Docks and Har ...
