Gondola (rail)
In US railroad terminology, a gondola is an open-topped rail vehicle used for transporting loose bulk materials. Because of their low side walls, gondolas are also suitable for the carriage of such high-density cargos as steel plates or coils, or of bulky items such as prefabricated sections of rail track. Gondolas are distinct from hopper cars in that they do not have doors on their floor to empty cargo. In Australia these wagons are called ''open wagons''. History The first gondola cars in North America were developed in the 1830s, and used primarily to carry coal. Early gondolas were little more than flatcars with wooden sides added, and were typically small – or less in length, and or less in weight. These cars were not widely used at first, as they could only be unloaded by workers shoveling out their cargo by hand, a slow and labor-intensive process. A solution for this problem was developed around the 1860s with the drop-bottom gondola, which had hatches installed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railgon Company
The Railgon Company, (reporting marks GONX GNTX) established in 1979, owned railroad gondola cars available for use by multiple railroads by placing the cars in a cooperative pool. Shipments in gondola cars and other rolling stock are often used to transport goods on more than one railroad before reaching the receiver. Under the regulations governing railway transport, individual railroads paid fees, called car hire, for the time and mileage to utilize other railroads’ railcars (whether loaded or empty) Car hire was designed to promote the rapid return of rolling stock, since delays equated to extra money spent. Because of the desire to reduce costs by minimizing car hire, non-owning railroads may have declined the practice of allowing cars to continue on past their initial destination to points further from the car's "home". This had the effect of decreasing efficiency on these lines, and Railgon (and Railbox) used this argument to promote use of their rolling stock. Railroad ...

Quarry Tub
A tub or quarry tub is a type of railway or tramway wagon used in quarries and other industrial locations for the transport of minerals (such as coal, sand, ore, clay and stone) from a quarry or mine face to processing plants or between various parts of an industrial site. This type of wagon may be small enough for one person to push, or designed for haulage by a horse, or for connection in a train hauled by a locomotive. The tubs are designed for ease of emptying, usually by a side-tipping action. This type of rail vehicle is now mainly obsolete, its function having been mostly replaced by conveyor belts.

Mine Railway
A mine railway (or mine railroad, U.S.), sometimes pit railway, is a railway constructed to carry materials and workers in and out of a mine. Materials transported typically include ore, coal and overburden (also called variously spoils, waste, slack, culm, and tilings; all meaning waste rock). It is little remembered, but the mix of heavy and bulky materials which had to be hauled into and out of mines gave rise to the first several generations of railways, at first made of wooden rails, but eventually adding protective iron, steam locomotion by fixed engines and the earliest commercial steam locomotives, all in and around the works around mines. History Mine rails Wagonways (or tramways) were developed in Germany in the 1550s to facilitate the transport of ore tubs to and from mines, using primitive wooden rails. Such an operation was illustrated in 1556 by Georgius Agricola of Germany (Image right). This used "Hund" carts with unflanged wheels running on wooden planks an ...

Mineral Wagon
A mineral wagon or coal truck (British English) is a small open-topped railway goods wagon used in the United Kingdom and elsewhere to carry coal, ores and other mine products. Background When the railways originated in the United Kingdom, the initial rules and laws of passage were based on those used on the roads. Hence the railway companies provided the track (road) and initially it was proposed that the owner of the goods being transported would either provide and operate their own train (locomotive and wagons) or obtain the services of an agent to do so. This 'open access' model quickly proved impractical so the emerging railway industry settled on a compromise of the railway company providing the route and locomotive and being responsible for their organisation and control, while the wagons and vans that transported the actual cargo remained in private hands. As a step further towards the old open access arrangements some of the early long-distance railways contracted with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minecart
A minecart or mine cart (also known as a mine trolley or mine hutch) is a type of rolling stock found on a mine railway, used for moving ore and materials procured in the process of traditional mining. Minecarts are seldom used in modern operations, having largely been superseded in underground operations (especially coal mines) by more efficient belt conveyor systems that allow machines such as longwall shearers and continuous miners to operate at their full capacity, and above ground by large dumpers. Terminology Throughout the world, there are different titles for mine carts. In South Africa, a minecart is referred to as a ; in German, it is called (alternative spelling ). In Wales, minecarts are known as drams. In the U.S. and elsewhere, the term skip – or skip wagon (older spelling: ''waggon'') – is used. (See: Skip (container)#Etymology) In particular, a V skip wagon is a side-tipping skid with a V-shaped body. (Images) Design and operation Minecarts range in ...

Corf (mining)
A corf (pl. corves) also spelt corve (pl. corves) in mining is a wicker basket or a small human powered (in later times in the case of the larger mines, horse drawn) minecart for carrying or transporting coal, ore, etc. Human powered corfs had generally been phased out by the turn of the 20th century, with horse drawn corfs having been mostly replaced by horse drawn or motorised minecarts mounted on rails by the late 1920s. Also similar is a Tram, originally a box on runners, dragged like a sledge. Origin of term 1350–1400; Middle English from Dutch and German ''Korb'', ultimately borrowed from Latin ''corbis'' basket; cf. ''corbeil''. Survivors The National Coal Mining Museum for England has a hazel basket type Corf from William Pit near Whitehaven.

Chaldron
A chaldron (also chauldron or chalder) was an English measure of dry volume, mostly used for coal; the word itself is an obsolete spelling of cauldron. It was used from the 13th century onwards, nominally until 1963, when it was abolished by the Weights and Measures Act 1963, but in practice until the end of 1835, when the Weights and Measures Act of that year specified that thenceforth coal could only be sold by weight. Coal The chaldron was used as the measure for coal from the 13th century, measuring by volume being much more practical than weighing low-value, high-bulk commodities like coal. It was not standardized, and there were many different regional chaldrons, the two most important being the Newcastle and London chaldrons. The Newcastle chaldron was used to measure all coal shipped from Northumberland and Durham, and the London chaldron became the standard measure for coal in the east and south of England. Many attempts have been made to calculate the weight of a Newc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

30-cu
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Track Ballast
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it. A variety of materials have been used as track ballast, including crushed stone, washed gravel, bank run (unwashed) gravel, torpedo gravel (a mixture of coarse sand and small gravel), slag, chats, coal cinders, sand, and burnt clay. The term "ballast" comes from a nautical term for the stones used to stabilize a ship. Construction The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast should never be laid down less than thick, and high-speed railway lines may require ballast up to thick.Bell 2004, p. 39 ...
