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 bo ... [...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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 locomotiv ...

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-2 ...

Tank Engine
A tank locomotive or tank engine is a steam locomotive that carries its water in one or more on-board water tanks, instead of a more traditional tender. Most tank engines also have bunkers (or fuel tanks) to hold fuel; in a tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for shunting and shorter-distance main line duties. Tank locomotives have advantages and disadvantages compared to traditional locomotives that required a separate tender to carry needed water and fuel. History Origins The first tank locomotive was the ''Novelty'' that ran at the Rainhill Trials in 1829. It was an example of a ''Well Tank''. However, the more common form ...

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 Trevith ...

Articulated Locomotive
An articulated locomotive is a steam locomotive (rarely, an electric locomotive) with one or more engine units that can move independent of the main frame. Articulation allows the operation of locomotives that would otherwise be too large to negotiate a railroad's curves, whether mainlines or special lines with extreme curvature such as logging, industrial, or mountain railways. Articulated locomotives saw service in many nations, but were very popular on narrow-gauge railways in Europe. The largest examples were developed in the United States, where the Union Pacific Big Boy 4-8-8-4s and the Allegheny H-8 2-6-6-6s were some of the largest steam locomotives ever built. Many schemes for articulation were developed over the years. Of these, the Mallet locomotive and its simple-expansion derivative were the most popular, followed by the Garratt type (mostly built in the United Kingdom, popular throughout Europe, Africa and European colonies), and the various geared steam locomo ...

Fairlie Locomotive
A Fairlie is a type of articulated steam locomotive that has the driving wheels on bogies. The locomotive may be double-ended (a double Fairlie) or single ended (a single Fairlie). Fairlies are most famously associated with the Ffestiniog Railway in North Wales. While the Fairlie locomotives are now used only on heritage railways, the vast majority of diesel and electric locomotives in the world today follow a form not very different from the Fairlie — two power trucks with all axles driven, and many also follow the Fairlie's double-ended concept, capable of being driven equally well in both directions. Development of the design The Scottish engineer Robert Francis Fairlie patented his design in 1864. He had become convinced that the conventional pattern of locomotive was seriously deficient; they wasted weight on unpowered wheels (the maximum tractive effort a locomotive can exert is a function of the weight on its driving wheels) and on a tender that did nothing b ...

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 ...

Meyer Locomotive
A Meyer locomotive is a type of articulated locomotive. The design was never as popular as the Garratt or Mallet locomotives. It can be best regarded as 19th Century competition for the early compound Mallet and also the Fairlie articulated designs. Most single cab modern trains are of a similar design such as power cars, freight diesel locomotives, and some passenger locomotives. Development and design The Meyer was in fact invented by Austrian engineer Wenzel Günther of the Wiener Neustädter Lokomotivfabrik for the Semmering Trials of 1851. However, the technology wasn't yet developed for the steam to be reliably transported to the bogies with reasonable amount of leaks, and despite generally good performance of the design on the trials the company abandoned the idea. It was reinvigorated by Frenchman Jean-Jacques Meyer (1804-1877), who took out a patent on the design in 1861. The first locomotive, an named ''L'Avenir'' (Future), was built by in 1868 with the support of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
