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 ...

Mechanical Engineering
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches. Mechanical engineering requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Standard-gauge Railway
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Garratt Articulated Steam Locomotive -- Concept Diagram
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 locomotive, articulated into three parts. Its boiler, Firebox (steam engine), firebox, and Cab (locomotive), 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 engines, 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.

New South Wales Government Railways
The New South Wales Government Railways (NSWGR) was the agency of the Government of New South Wales that administered rail transport in New South Wales, Australia, between 1855 and 1932. Management The agency was managed by a range of different commission structures between 1857 and 1932, which reported to either the Minister for Public Works or the Minister for Transport. The inaugural Chief Commissioner was Ben Martindale and, following the enactment of the he became Commissioner of Railways. John Rae succeeded Martindale in 1861, and in 1877 Charles Goodchap was appointed Commissioner. The set up a corporate body of three railway commissioners to manage the railways and remove them from political influence, resulting in the resignation of Goodchap. This Board of Railway Commissioners of New South Wales was in place from 22 October 1888 to 4 April 1907, and was replaced by a sole Chief Commissioner of Railways and Tramways until 22 March 1932, when a panel arrangement w ...
