Vauclain Compound Locomotives
The Vauclain compound was a type of compound steam locomotive that was briefly popular from the early 1890’s to the mid-1900’s. Developed by the Baldwin Locomotive Works, it featured two pistons moving in parallel, driving a common crosshead and controlled by a common valve gear using a single, complex piston valve. Advantages and disadvantages The arrangement's claimed advantage, as with other compounding arrangements, was greater economy due to lower fuel and water consumption. In practice uneven forces at the crosshead produced excess wear, with increased maintenance costs thus offsetting any fuel economies. The compounding system's integration into the cylinder saddle made conversion to conventional engines straightforward, so most Vauclain compounds were converted to normal locomotives thereafter. The last known operable example was Manitou and Pikes Peak Railway No. 4, which is now preserved on-site as a static display with its sister #5. Design The key to the Vauclai ...

Engine 618, Canada Atlantic Railway
An engine or motor is a machine designed to convert one or more forms of energy into motion (physics), mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. Geothermal energy, geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a ...

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the oldest railroads in North America, oldest railroad in the United States and the first steam engine, steam-operated common carrier. Construction of the line began in 1828, and it operated as B&O from 1830 until 1987, when it was merged into the Chessie System. Its lines are today controlled by CSX Transportation. Founded to serve merchants from Baltimore who wanted to do business with settlers crossing the Appalachian Mountains, the railroad competed with several existing and proposed Central Avenue (Albany, New York), turnpikes and canals, including the Erie Canal, Erie and Chesapeake and Ohio Canal. The railroad began operation in 1830 on a 13-mile line between Baltimore and Ellicott City, Maryland, Elliot's Mill in Maryland. Horse-drawn cars were replaced by steam locomotives the following year. Over the following decades, construction continued westward. During the American Civil War, the railroad sustained much damage but proved cru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railworld
Railworld Wildlife Haven is a charity in Peterborough which has a nature haven, a model railway and other exhibits. It is located on a landscaped former coal storage yard which once served Peterborough Power Station. It was founded by Rev. Richard Paten (1932-2012) in 1985 as the "Museum of World Railways" (MWR), changing its name to "Railworld" in 1992 and is now called "Railworld Wildlife Haven" in reference to its change of focus towards its landscaped nature area. The centre is open only on certain days. It is located beside the Peterborough Nene Valley railway station, but it is a separate organisation. Exhibits In reference to its previous function as a railway museum, there is a small collection of locomotives and railway memorabilia, all of which require extensive work. There are two unique vehicles: * Tracked Hovercraft RTV 31, a prototype hover train which was tested in the Cambridgeshire Fens. * The Birmingham AirRail Link Maglev vehicle. Other locomotive ar ...

DSB (railway Company)
DSB, an abbreviation of ''Danske Statsbaner'' (, ''Danish State Railways''), is the largest Danish train operating company. It's also the largest train operating company in Scandinavia. While DSB is responsible for passenger train operation on most of the Danish railways, goods transport and railway maintenance are outside its scope. DSB runs a commuter rail system, called the S-train, in the area around the Danish capital, Copenhagen, that connects the different areas and suburbs in the greater metropolitan area. Between 2010 and 2017, DSB operated trains in Sweden. DSB was founded in 1885, when the state-owned companies ''De jysk-fynske Statsbaner'' and ''De sjællandske Statsbaner'' merged. DSB was established in 1885, after the state in 1867 under the name De Jutland-Fynske Statsbaner took over the private company Det Danske Jernbanedriftselskab and in 1880 they also took over the privately owned Zealand Railway Company.

2-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s ''Consolidation'', the name of the first 2-8-0.White, John H. Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York: Dover Publications, p. 65. The notation 2-8-0T indicates a tank locomotive of this wheel arrangement, the "T" suffix indicating a locomotive on which the water is carried in side-tanks mounted on the engine rather than in an attached tender (rail), tender. The Consolidation represented a notable advance in locomotive power. After 1875, it became "the most popular type of freight locomotive in the United States and was built in greater quantities tha ...

Walschaerts Valve Gear
The Walschaerts valve gear is a type of valve gear used to regulate the flow of steam to the pistons in steam locomotives, invented by Belgium, Belgian railway mechanical engineering, engineer Egide Walschaerts in 1844. The gear is sometimes named without the final "s", since it was incorrectly patented under that name. It was extensively used in steam locomotives from the late 19th century until the end of the steam era. History The Walschaerts valve gear was slow to gain popularity. The Stephenson valve gear remained the most commonly used valve gear on 19th-century locomotives. However, the Walschaerts valve gear had the advantage that it could be mounted entirely on the outside of the locomotives, leaving the space between the locomotive frame, frames clear and allowing easy access for service and adjustment, which resulted in it being adopted in some articulated locomotives. The first locomotive fitted with the Walschaerts valve gear was built in 1849 at the Belgian Tubiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L241, Turntable, Ca
L, or l, is the twelfth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''el'' (pronounced ), plural ''els''. History Lamedh may have come from a pictogram of an ox goad or cattle prod. Some have suggested that it represents a shepherd's staff. Typographic variants In most sans-serif typefaces, the lowercase letter ''ell'' , written as the glyph , may be difficult to distinguish from the uppercase letter "eye" (written as the glyph ); in some serif typefaces, the glyph may be confused with the glyph , the digit ''one''. To avoid such confusion, some newer computer fonts (such as Trebuchet MS) have a finial, a curve to the right at the bottom of the lowercase letter ''ell''. Other style variants are provided in script typefaces and display typefaces. All these variants of the letter are encoded in Unicode as or , allowing presentation to be chosen accord ...

Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, in some steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in the radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace, in the path of the hot flue gases, usually ahead of an economizer. A convection superheater is also called a primary superheater. * A separately fired superheater is a superheater that is placed outside the main boiler and has its own separate combustion system. This superheater design incorporates additional burners i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliott Cresson Medal
The Elliott Cresson Medal, also known as the Elliott Cresson Gold Medal, was the highest award given by the Franklin Institute. The award was established by Elliott Cresson, life member of the Franklin Institute, with $1,000 granted in 1848. The endowed award was to be "for a discovery in the Arts and Sciences, or for the invention or improvement of some useful machine, or for a new process or combination of materials in manufactures, or for ingenuity skill or perfection in workmanship." The medal was first awarded in 1875, 21 years after Cresson's death. The Franklin Institute continued awarding the medal on an occasional basis until 1998 when they reorganized their endowed awards under one umbrella, The Benjamin Franklin Awards. List of recipients A total of 268 Elliott Cresson Medals were given out during the award's lifetime.

Philadelphia And Reading Railroad
The Reading Company ( ) was a Philadelphia-headquartered railroad that provided passenger and freight transport in eastern Pennsylvania and neighboring states from 1924 until its acquisition by Conrail in 1976. Commonly called the Reading Railroad and logotyped as Reading Lines, the Reading Company was a railroad holding company for most of its existence, and a single railroad in its later years. It operated service as Reading Railway System and was a successor to the Philadelphia and Reading Railway Company, founded in 1833. Until the decline in anthracite shipments from the Coal Region in Northeastern Pennsylvania following World War II, it was one of the most prosperous corporations in the United States. Enactment of the federally-funded Interstate Highway System in 1956 led to competition from the modern trucking industry. They used the Interstates for short-distance transportation of goods, which compounded the company's competition for freight business, forcing it into ba ...

Norfolk And Western Railway
The Norfolk and Western Railway , commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America". In 1986, N&W merged with Southern Railway to form today's Norfolk Southern Railway. The N&W was famous for manufacturing its own steam locomotives, which were built at the Roanoke Shops, as well as its own hopper cars. After 1960, N&W was the last major Class I railroad using steam locomotives; the last remaining Y class 2-8-8-2s would eventually be retired in 1961. In December 1959, the N&W merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the Nickel Plate Road and Wabash formed a system that operated of road on of track from North Carolina to Ne ...
