Steam Dummy
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 railroad passenger coach. Steam dummies had some popularity in the first decades of railroading in the U.S., from the 1830s but passed from favor after the 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 Sydney, Australia - where they were known as ' steam tram motors' - and New Zealand, where two, both built in 1891, survive ...

Mammoth Cave Railroad Dummy Steam Engine
A mammoth is any species of the extinct elephantid genus ''Mammuthus'', one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago, and various species existed in Africa, Europe, Asia, and North America. They were members of the family Elephantidae, which also contains the two genera of modern elephants and their ancestors. Mammoths are more closely related to living Asian elephants than African elephants. The oldest representative of ''Mammuthus'', the South African mammoth (''M. subplanifrons''), appeared around 5 million years ago during the early Pliocene in what is now southern and eastern Africa. Descendant species of these mammoths moved north and continued to propagate into numerous subsequent speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 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 dominant. Usage Cape of Good Hope In 1899 ...

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 and elsewhere 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 the customary hors ...

Multiple Unit
A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined together, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control. Although multiple units consist of several carriages, single self-propelled carriages – also called railcars, rail motor coaches or railbuses – are in fact multiple-units when two or more of them are working connected through multiple-unit train control (regardless if passengers can walk between the units or not). History Multiple-unit train control was first used in electric multiple units in the 1890s. The Liverpool Overhead Railway opened in 1893 with two-car electric multiple units, controllers in cabs at both ends directly controlling the traction current to motors on both cars. The multiple-unit traction control system was developed by Frank Sprague and first applied and tested on the South Side Elevated Railroad (n ...

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 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 with larger crew. Several railroads, mostly small r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 followed in the next two years. Returning to the 517 class, various bunker and cab combinations also evolved, and after their last rebuilding, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 swit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Western Railway
The Great Western Railway (GWR) was a British railway company that linked London with the southwest, west and 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 amalgamations saw it also operate 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 nationalised and became the Western Region of British Railways. The GWR was called by some "God's Wonderful Railway" and by others the "Great Way Round" but it was famed as the "Holi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. 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 oil in oil refineries. Coke may also be formed naturally by 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. History China Historical sources dating to the 4th century describe the production of coke in ancient China. The Chinese first used coke for heatin ...

Anthracite
Anthracite, also known as hard coal, and black coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 97%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. The Coal Region of northeastern P ...

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-equipped tank locomotive. The arrangement is sometimes known as Olomana after a Hawaiian 0-4-2 locomotive of 1883. 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'', was also an . In the same year Todd, Kitson & Laird built two examples for the Liverpool and Manchester Railwa ...
