Kylchap Schem
The Kylchap steam locomotive exhaust system was designed and patented by French steam engineer André Chapelon, using a second-stage nozzle designed by the Finnish engineer Kyösti Kylälä and known as the ''Kylälä spreader''; thus the name KylChap for this design. Construction The Kylchap exhaust consists of four stacked nozzles, the first exhaust nozzle (UK: blastpipe) blowing exhaust steam only and known as the primary nozzle, this being a Chapelon design using four triangular jets. This exhausts into the second stage, the Kylälä spreader, which mixes the exhaust steam with some of the smokebox gases; this then exhausts into a third stage, designed by Chapelon, that mixes the resulting steam/smokebox gases mixture with yet more smokebox gases. The four nozzles of this then exhaust into the fourth stage, the classic chimney (U.S.: stack) bell-mouth. Theory It was Chapelon's theory that such a multi-stage mixing and suction arrangement would be more efficient than the sing ...

Arthur Peppercorn
Arthur Henry Peppercorn, (29 January 1889 – 3 March 1951) was an English railway engineer, and was the last Chief Mechanical Engineer (CME) of the London and North Eastern Railway. Career Arthur Peppercorn was born in Leominster in 1889 and educated at Hereford Cathedral School. In 1905 he started his career as an apprentice with the Great Northern Railway (GNR) at Doncaster. Gresley took a liking to the young apprentice and would supervise his career; in turn, Peppercorn was devoted to Gresley, and would in time be treated almost like one of the family. Gresley's sudden death in 1941 was a shock to all in the LNER, and although Peppercorn was considered for the role, his great modesty in comparison with that of the other candidate, Edward Thompson, as well as the influence Thompson held within the LNER seniority meant that it was Thompson who succeeded Gresley. Thompson was already 60 years old, and both he and the LNER recognised that his appointment was not a perman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk & Western
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 between 1964 and 1965. 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 New York, Chicago & St. Louis Railroad, Nickel Plate Road and Wabash Railroad, Wabash formed a ...

Lemprex Ejector
A Lemprex ejector is a type of Steam locomotive exhaust system developed by noted Argentinian locomotive engineer Livio Dante Porta (d. 2003). The name is a stylization of LeMaitre Porta Exhaust. In a steam locomotive, draft is produced in the firebox by exhausting the steam coming from the cylinders out the chimney. The Lemprex exhaust will deliver improved draughting capacity over traditional exhaust systems. However development is only at an early stage. Some work was undertaken in Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area ... during the late 1980s and early 90s. During more recent years locomotive engineer Shaun T. Mc Mahon has continued the development of this exhaust system in Argentina and other countries around the World, current development work being focussed ...

Lempor Ejector
The Lempor ejector is a steam locomotive exhaust system developed by noted Argentine locomotive engineer Livio Dante Porta. The ejector's name is a portmanteau of the names of Porta and Belgian locomotive engineer Maurice Lemaître. Operation In a steam locomotive, draft is produced in the firebox Firebox may refer to: *Firebox (steam engine), the area where the fuel is burned in a steam engine *Firebox (architecture), the part of a fireplace where fuel is combusted *Firebox Records Firebox Records was a Finnish record label based in S ... by exhausting the steam coming from the cylinders into the Chimney via a nozzle or 'blast pipe' this creates a vacuum in the Smokebox. The Lempor ejector is a development of similar multiple orifice/nozzle ejectors which create either a stronger vacuum or the same vacuum more efficiently by presenting less 'back pressure' or resistance to the exhausting cylinder. Results The Lempor exhaust is claimed to deliver a 100% improvement in drau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Livio Dante Porta
Livio Dante Porta (21 March 1922 – 10 June 2003) was an Argentine steam locomotive engineer. He is particularly remembered for his innovative modifications to existing locomotive systems in order to obtain better performance and energy efficiency, and reduced pollution. He developed the Kylpor and Lempor exhaust systems. The Lemprex was under development at the time of his death. Early years Porta was born in Paraná, Entre Ríos, and studied civil engineering, concluding his studies in 1946, at a time when steam was already giving way to diesel and electric locomotives in Europe and North America. Career Naturally, Porta's first projects were in Argentina. Taking the work of Andre Chapelon in France as his starting point, he set out to demonstrate that the steam locomotive was far from reaching its maximum potential. His first locomotive project in 1948 took the remains of a 4-6-2 converting it into a 4-cylinder compound 4-8-0 named 'Presidente Peron'/'Argentina'. T ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Lemaître Exhaust
The Lemaître exhaust is a type of steam locomotive exhaust system developed by the Belgian engineer Maurice Lemaître. Construction The Lemaître exhaust featured a blastpipe with 5 nozzles in a circular pattern exhausting up a large-diameter chimney stack, with a variable area nozzle exhausting up the centre, and improved efficiency by about 10%. Uses The Lemaître exhaust was used extensively in Great Britain by OVS Bulleid on his new locomotive designs for the Southern Railway, namely the Merchant Navy, Light Pacific and Q1 classes. Bulleid also retro-fitted Lemaître exhausts on some older classes, such as the SR Lord Nelson class and some of the SR V Schools class. Further Development The design was later improved by Livio Dante Porta, who created the Lempor The Lempor ejector is a steam locomotive exhaust system developed by noted Argentina, Argentine locomotive engineer Livio Dante Porta.

Garratt
A Garratt (often referred to as a Beyer Garratt) is a type of steam locomotive invented by British engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage. Articulation permits locomotives to negotiate curves that might restrict large rigid-framed locomotives. The design also provides more driving wheels per unit of locomotive weight, permitting operation on lightly engineered track. Garratt locomotives produced as much as twice the power output of the largest conventional locomotives of railways that introduced them, reducing the need for multiple locomotives and crews. Advantages of the Garratt concept The principal benefit of the Garratt design is that the boil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BR Standard Class 8
The BR Standard Class 8 was a class of a single 4-6-2 ''Pacific'' steam locomotive designed by Robert Riddles for use by British Railways. Only the prototype was constructed, named ''Duke of Gloucester''. Constructed at Crewe Works in 1954, the ''Duke'', as it is popularly known, was a replacement for the destroyed LMS Princess Royal Class locomotive number 46202 ''Princess Anne'', which was involved in the Harrow and Wealdstone rail crash of 1952. The ''Duke'' was based on the BR Standard Class 7 ''Britannia'' design. It incorporated three sets of modified Caprotti valve gear, relatively new to British locomotive engineering and more efficient than Walschaerts or Stephenson valve gear. The ''Duke'' was regarded as a failure by locomotive crews due to its poor steaming characteristics and its heavy fuel consumption. Trials undertaken by British Railways also returned negative feedback, reporting problems with the poor draughting of the locomotive which resulted in difficulty a ...
