Dummy Engine
A steam dummy or dummy engine, in the United States and Canada, was a steam locomotive enclosed in a wooden box structure made to resemble a passenger railroad car. Steam dummies had some popularity in the first decades of railroading in the U.S., from the 1830s but passed from favor after the American Civil War. Overview It was thought that the more familiar appearance of a coach presented by a steam dummy, as compared to a conventional steam locomotive, would be less likely to frighten horses when these trains had to operate in city streets. Later it was realized that it was actually the noise and motion of the operating gear of a steam engine that frightened horses, rather than the unfamiliar outlines of a steam engine. Production Baldwin Locomotive Works manufactured steam dummies or steam motors for many American tramways. Baldwin exported to places such as Australia where they were known as ' steam tram motors' – and New Zealand, where two, both built in 1891, survive a ...

Mammoth Cave Railroad Dummy Steam Engine
A mammoth is any species of the extinct elephantid genus ''Mammuthus.'' They lived from the late Miocene epoch (from around 6.2 million years ago) into the Holocene until about 4,000 years ago, with mammoth species at various times inhabiting Africa, Asia, Europe, and North America. Mammoths are distinguished from living elephants by their (typically large) spirally twisted tusks and in some later species, the development of numerous adaptions to living in cold environments, including a thick layer of fur. Mammoths and Asian elephants are more closely related to each other than they are to African elephants. The oldest mammoth representative, '' Mammuthus subplanifrons'', appeared around 6 million years ago during the late Miocene in what is now southern and Eastern Africa.'''' Later in the Pliocene, by about three million years ago, mammoths dispersed into Eurasia, eventually covering most of Eurasia before migrating into North America around 1.5–1.3 million years ...

2-4-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, four powered and coupled driving wheels on two axles and two trailing wheels on one axle. The type is sometimes named Columbia after a Baldwin Locomotive Works, Baldwin locomotive was showcased at the 1893 World's Columbian Exposition held at Chicago, Illinois. Overview The wheel arrangement was widely used on passenger tank locomotives during the last three decades of the nineteenth and the first decade of the twentieth centuries. The vast majority of 2-4-2 locomotives were Tank locomotive, tank engines, designated 2-4-2T. The symmetrical wheel arrangement was well suited for a tank locomotive that is used to work in either direction. When the leading and trailing wheels are in swivelling trucks, the equivalent UIC classification is 1'B1'. While a number of 2-4-2 tender locomotives were built, larger tender locomotive types soon became do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tram Engine
A tram engine is a steam locomotive specially built, or modified, to run on a street, or roadside, tramway track. Legal requirements In the steam locomotive era, tram engines had to comply with certain legal requirements, although these varied from country to country: * The engine must be governed to a maximum speed of ( in the UK) * No steam or smoke may be emitted * It must be free from the noise produced by blast or clatter * The machinery must be concealed from view at all points above from rail level *Most of the locomotives must have a cab at each end To avoid smoke, the fuel used was coke, rather than coal. To prevent visible emission of steam, two opposite systems were used: * condensing the exhaust steam and returning the condensate to the water tank * Reheating the exhaust steam to make it invisible Builders United Kingdom ;Great Eastern Railway The Great Eastern Railway built ten Class G15 0-4-0T trams from 1883 to 1897 and twelve Class C53 0-6-0T trams ...

Railmotor
Railmotor is a term used in the United Kingdom, Ireland and the Commonwealth for a railway lightweight railcar, usually consisting of a railway carriage with a steam traction unit, or a diesel or petrol engine, integrated into it. Steam railcars Overview In the earliest days of railways, designers wished to produce a vehicle for passenger carrying that was economical to build and operate on routes where passenger numbers were light. A single coach with its own prime mover was a solution adopted in some cases; this may be thought of as the predecessor to the railcar, a term more associated with the use of internal combustion engines. William Bridges Adams started building railmotors in small numbers as early as 1848. The Bristol and Exeter Railway used a steam carriage. In most cases the early designs were unsuccessful technically, but in the early years of the twentieth century, street-running passenger tramways started to use small steam engines to draw tramcars, replacing ...

Multiple Unit
A multiple-unit train (or multiple unit (MU)) is a self-propelled train composed of one or more Coach (rail), carriages joined, and where one or more of the carriages have the means of propulsion built in. By contrast, a locomotive-hauled train has all of the carriages unpowered. An implication of this is that all the powered carriages needs to be controllable by a single engineer or driver, which is a case of the broader concept of multiple-unit train control. In other words, all "multiple units" employ some variation of multiple-unit train control. In the broader context "unit" means any powered rail vehicle, including locomotives (that does not carry cargo) and powered cargo-carrying carriages. In the context of this article, "unit" refers specifically to the latter only (whether the cargo is passengers or some other cargo). What follows is that if coupled to another multiple unit, all MUs can still be controlled by the single driver, with multiple-unit train control. ...

Doodlebug (rail Car)
Doodlebug or hoodlebug is a nickname in the United States for a type of self-propelled railcar most commonly configured to carry both passengers and freight, often dedicated baggage, mail or express, as in a combine. The term has been used interchangeably with jitney. The name is said to have derived from the insect-like appearance of the units, as well as the slow speeds at which they would doddle or "doodle" down the tracks. Early models were usually powered by a gasoline engine, with either a mechanical drive train or a generator providing electricity to traction motors ("gas-electrics"). In later years, it was common for doodlebugs to be repowered with a diesel engine. Doodlebugs sometimes pulled an unpowered trailer car, but were more often used singly. They were popular with some railroads during the first part of the 20th century to provide passenger and mail service on lightly used branch lines at less expense than with a train consisting of a locomotive and coaches ...

GWR 517 Class
The 517 Class were small 0-4-2T tank engines designed by George Armstrong for local passenger work on the Great Western Railway. They were built at Wolverhampton Works and were outshopped between 1868 and 1885. They were built in thirteen lots commencing with 517–528 and ending with 1477–1488 in 1884–1885. Dimensions The class was far from uniform and encompassed three different wheelbases, saddle and side tanks, and various boilers to name just a few variations. Driving wheels were (later due to thicker tyres), cylinders , (later ) and boiler pressure (later ). Summary table When new, the first sixty were numbered 1040–87 (Lots D to G inclusive) and 1100–11 (Lot H); they were renumbered 517–576 in July 1870. History The earlier ones were rebuilt from saddle tanks while the later ones were built as side tanks from the beginning. The 3571 Class were very closely related, its prototype being a minor rebuild of 517 class No. 1477 in 1895. Then ten new locos f ...

GWR 2021 Class
The GWR 2021 Class was a class of 140 steam locomotives. They were built at the Wolverhampton railway works of the Great Western Railway between 1897 and 1905. 1897 was the very year of George Armstrong's retirement, so it is uncertain if the design should be attributed to him or to his superior at Swindon, William Dean. In fact the 2021s were simple enlargements of the Armstrong-designed 850 class of 1874. The changes were fundamentally confined to a longer wheelbase to permit fitting of a larger firebox. History The class was built in eight batches: * 2021-2030 (Lot D3, 1897) * 2031-2040 (Lot F3, 1897–8) * 2041-2060 (Lot G3, 1898–9) * 2061-2080 (Lot H3, 1899–1900) * 2081-2100 (Lot J3, 1900–01) * 2101-2120 (Lot K3, 1902–3) * 2121-2140 (Lot L3, 1903–4) * 2141-2160 (Lot M3, 1904–5) Rebuilding with Belpaire fireboxes commenced in the early years of the Churchward era. Unsuccessful attempts to form a saddle tank around the firebox directly led to the switch t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Western Railway
The Great Western Railway (GWR) was a History of rail transport in Great Britain, British railway company that linked London with the southwest, west and West Midlands (region), West Midlands of England and most of Wales. It was founded in 1833, received its enabling act of Parliament on 31 August 1835 and ran its first trains in 1838 with the initial route completed between London and Bristol in 1841. It was engineered by Isambard Kingdom Brunel, who chose a broad gauge of —later slightly widened to —but, from 1854, a series of Consolidation (business), amalgamations saw it also operate Standard gauge, standard-gauge trains; the last broad-gauge services were operated in 1892. The GWR was the only company to keep its identity through the Railways Act 1921, which amalgamated it with the remaining independent railways within its territory, and it was finally merged at the end of 1947 when it was Nationalization, nationalised and became the Western Region of British Railways. ...

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude petroleum in oil refinery, petroleum refineries. Coke may also be formed naturally by geology, geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. It is the residue of a destructive distillation process. Production Industrial coke furnaces The industrial production of coke from coal is called coking. The coal is baked in an airless k ...

0-4-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement with no leading wheels, four powered and coupled driving wheels on two axles and two trailing wheels on one axle. While the first locomotives of this wheel arrangement were tender engines, the configuration was later often used for tank engines, which is noted by adding letter suffixes to the configuration, such as for a conventional side-tank locomotive, for a saddle-tank locomotive, for a well-tank locomotive and for a rack railway, rack-equipped tank locomotive. Overview The earliest recorded locomotives were three goods engines built by Robert Stephenson and Company for the Stanhope and Tyne Railway in 1834. The first locomotive built in Germany in 1838, the ''Saxonia (locomotive), Saxonia'', was also an . In the same year Kitson and Company, Todd, Kitson & Laird built two examples for the Liverpool and Manchester Railway, one of which, LMR 57 Lion, has been preserve ...
