Vauclain Compound
The Vauclain compound was a type of compound steam locomotive that was briefly popular circa 1900. Developed at 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 claimed advantage for this arrangement, 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 integration of the compounding system into the smokebox saddle made conversion to conventional engines straightforward, so most Vauclain compounds were so converted and led normal lives thereafter. The only known operable example is Manitou and Pikes Peak Railway No. 4, which is preserved on-site along with the static display of its sister #5. Design The key to the Vauclain compound is i ...

Lehigh Valley Railroad
The Lehigh Valley Railroad was a railroad built in the Northeastern United States to haul anthracite coal from the Coal Region in Pennsylvania. The railroad was authorized on April 21, 1846 for freight and transportation of passengers, goods, wares, merchandise and minerals in Pennsylvania and the railroad was incorporated and established on September 20, 1847 as the Delaware, Lehigh, Schuylkill and Susquehanna Railroad Company. On January 7, 1853, the railroad's name was changed to Lehigh Valley Railroad. It was sometimes known as the Route of the Black Diamond, named after the anthracite it transported. At the time, anthracite was transported by boat down the Lehigh River. The railroad ended operations in 1976 and merged into Conrail along with several northeastern railroads that same year. The Lehigh Valley Railroad's original and primary route between Easton and Allentown was built in 1855. The line later expanded past Allentown to Lehigh Valley Terminal in Buffalo and pas ...

Wellington And Manawatu Railway Company
The Wellington and Manawatu Railway Company (WMR or W&MR) was a private railway company that built, owned and operated the Wellington-Manawatu railway line between Thorndon in Wellington, the capital of New Zealand, and Longburn, near Palmerston North in the Manawatu, between 1881 and 1908, when it was acquired by the New Zealand Government Railways. Its successful operation in private ownership was unusual for early railways in New Zealand. History At the time of the company's founding in 1881, the government had built the Foxton Branch railway linking Palmerston North and Foxton, and had completed surveys of lines down the west coast to Wellington. The government of Sir George Grey had approved the construction of the line, which was included in the Public Works Estimates of 27 August 1878. The final details of the survey were completed, and the first workers for the construction of the line were hired on 21 August 1879. A short section of the line, from Wellington to W ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peterborough
Peterborough () is a cathedral city in Cambridgeshire, east of England. It is the largest part of the City of Peterborough unitary authority district (which covers a larger area than Peterborough itself). It was part of Northamptonshire until 1974, when county boundary change meant the city became part of Cambridgeshire instead. The city is north of London, on the River Nene which flows into the North Sea to the north-east. In 2020 the built-up area subdivision had an estimated population of 179,349. In 2021 the Unitary Authority area had a population of 215,671. The local topography is flat, and in some places, the land lies below sea level, for example in parts of the Fens to the east and to the south of Peterborough. Human settlement in the area began before the Bronze Age, as can be seen at the Flag Fen archaeological site to the east of the current city centre, also with evidence of Roman occupation. The Anglo-Saxon period saw the establishment of a monastery, Medeshams ... [...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 locomotives are: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DSB (railway Company)
DSB, an abbreviation of ''Danske Statsbaner'' (, ''Danish State Railways''), is the largest Danish train operating company, and the largest 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. History The first railways in Denmark were built and operated by private companies. The railways in Funen and Jutland were built by Peto and Betts who also supplied the locomotives (built by Canada Works, Birkenhead). Most of the technical staff was also recruited from Britain, notably from the Eastern Counties Railway. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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 than any other si ...

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 at the Belgian Tubize worksh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L241, Turntable, Ca
L, or l, is the twelfth letter in 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 a shepherd's staff. Use in writing systems Phonetic and phonemic transcription In phonetic and phonemic transcription, the International Phonetic Alphabet uses to represent the lateral alveolar approximant. English In English orthography, usually represents the phoneme , which can have several sound values, depending on the speaker's accent, and whether it occurs before or after a vowel. The alveolar lateral approximant (the sound represented in IPA by lowercase ) occurs before a vowel, as in ''lip'' or ''blend'', while the velarized alveolar lateral approximant (IPA ) occurs in ''bell'' and ''milk''. This velarization does not occur in many European langu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 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 usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
