South Australian Railways Q Class
The South Australian Railways Q Class were steam locomotives constructed between 1885 and 1892 by Dübs and Company and James Martin & Co for the South Australian Railways (SAR). History The first batch of fifteen Q Class locomotives were purchased from Dübs and Company, Scotland to replace the unsuccessful N and O class locomotives on the South Australian Railways South Australian Railways (SAR) was the statutory corporation through which the Government of South Australia built and operated railways in South Australia from 1854 until March 1978, when its non-urban railways were incorporated into Austr ... "Intercolonial" hills line workings. With the new Q class locomotives being able to haul moderate loads on offer, these locomotives performed very well and the SAR ordered a second batch from the local James Martin & Co. Following the introduction of the more powerful R class locomotives on the southern line, the Q class was put to work on interstate trains from Mur ...

James Martin & Co
James Martin & Co was an Australian engineering company which progressed from making agricultural equipment to making railway locomotives. History James Martin & Co. was founded in Gawler, South Australia in around 1848 by James Martin as a blacksmith and wheelright business. It soon began to manufacture reapers. The opening of the Gawler railway line in 1857 allowed Adelaide to be accessed more easily. In 1858, Thomas Flett Loutit joined the business as a shareholder and steam power was introduced to the workshop. In 1868 Loutit retired due to ill health. In the 1870s, a new foundry was built on Calton Road.James Martin & Co Phoenix Foundry Town of Gawler During this period James Martin’s nephew, John Felix Martin (1844–1916) and Fred May joined him in partnership ...

4-4-0
4-4-0 is a locomotive type with a classification that uses the Whyte notation for the classification of steam locomotives by wheel arrangement and represents the arrangement: four leading wheels on two axles (usually in a leading bogie), four powered and coupled driving wheels on two axles, and a lack of trailing wheels. Due to the large number of the type that were produced and used in the United States, the 4-4-0 is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced.White, John H., Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York: Dover Publications, pp. 46-. Almost every major railroad that operated in North America in the first half of the 19th century owned and operated locomotives of this type. The first use of the name ''American'' to describe locomotives of this wheel arrangement was made by ''Railroad Gazette'' in April 1872. Prior to t ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as stratum, 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 formed when dead plant matter decays into peat and 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. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. 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 energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephenson Valve Gear
The Stephenson valve gear or Stephenson link or shifting link is a simple design of valve gear that was widely used throughout the world for various kinds of steam engines. It is named after Robert Stephenson but was invented by his employees. Historical background During the 1830s, the most popular valve drive for steam locomotives was known as '' gab motion'' in the United Kingdom and'' V-hook motion'' in the United States. The gab motion incorporated two sets of eccentrics and rods for each cylinder; one eccentric was set to give forward and the other backwards motion to the engine and one or the other could accordingly engage with a pin driving the distribution valve by means of the gabs: - vee-shaped ends to the eccentric rods supposed to catch the rocker driving the valve rod whatever its position. It was a clumsy mechanism, difficult to operate, and only gave fixed valve events. In 1841, two employees of Robert Stephenson and Company, draughtsman William Howe and patt ...

Piston Valve (steam Engine)
Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power. The valve consists of two piston heads on a common spindle moving inside a steam chest, which is essentially a mini-cylinder located either above or below the main cylinders of the locomotive. Overview In the 19th century, steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * It is difficult to lubricate slide valves adequately in the presence of superheated steam * With piston valves, the steam passages can be made shorter. This, particularly following the work of André Chapelon, reduces resistance to the flow of steam and improves e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australian Railways
South Australian Railways (SAR) was the statutory corporation through which the Government of South Australia built and operated railways in South Australia from 1854 until March 1978, when its non-urban railways were incorporated into Australian National, and its Adelaide urban lines were transferred to the State Transport Authority. The SAR had three major rail gauges: 1600 mm (5 ft 3 in); 1435 mm (4 ft in); and 1067 mm (3 ft 6 in). History Colonial period The first railway in South Australia was laid in 1854 between Goolwa and Port Elliot to allow for goods to be transferred between paddle steamers on the Murray River and seagoing vessels. The next railway was laid from the harbour at Port Adelaide, to the capital, Adelaide, and was laid with Irish gauge track. This line was opened in 1856. Later on, branch lines in the state's north in the mining towns of Kapunda and Burra were linked through to the Adelaide metrop ...

Scrap
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes. Scrap recycling is important for creating a more sustainable economy or creating a circular economy, using significantly less energy and having far less environmental impact than producing metal from ore. Metal recycling, especially of structural steel, ships, used manufactured goods, such as vehicles and white goods, is a major industrial activity with complex networks of wrecking yards, sorting facilities and recycling plants. Processing Scrap metal originates both in business and residential environments. Typically a "scra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotives
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 b ...

Double Heading
In railroad terminology, double heading indicates the use of two locomotives at the front of a train, each operated individually by its own crew. The practice of triple-heading involves the use of three locomotives. The practice of multi-heading involves the use of multiple locomotives and so on. Double heading is most common with steam locomotives, but is also practised with diesel locomotives. It is not strictly the same practice as two or more diesel or electric locomotives working ' in multiple' (or 'multiple-working'), where both (or all) locomotives are controlled by a single driver in the cab of the leading locomotive. Advantages Double heading is practised for a number of reasons: * In the UK it was usually to gain traction on steep inclines, twice the amount of driven wheels - twice the amount of grip. * The need for additional motive power when a single locomotive is unable to haul the train due to uphill grades, excessive train weight, or a combination of the t ...
