GNRI Class VS
The Great Northern Railway (Ireland) (GNRI) VS class steam locomotives were 4-4-0 three-cylinder simple expansion steam locomotives built in 1948 by Beyer, Peacock and Company. They were procured in order to operate the Enterprise train service between Dublin and Belfast and were the last series of steam engines ordered by the company. Design The locomotives of class VS, designed by Mcintosh, were very similar to the compound locomotives of GNRI Class V, built in 1932 by Beyer, Peacock and Company. Unlike the latter, however, they had only simple expansion steam engines with Walschaerts valve gear. Their wheel arrangement was due to the restricted space in the Dundalk workshops. Class VS used the same Belpaire boilers as class V with an evaporation surface of and a superheating surface of , and other parts were also interchangeable. The locomotives were equipped with smoke deflectors, rocking grates, hopper ashpans, and self-cleaning fireboxes with a grate area of , and were ...

Beyer, Peacock And Company
Beyer, Peacock and Company was an English general engineering company and railway locomotive manufacturer with a factory in Openshaw, Manchester. Charles Beyer, Richard Peacock and Henry Robertson founded the company in 1854. The company closed its railway operations in the early 1960s. It retained its stock market listing until 1976, when it was bought and absorbed by National Chemical Industries of Saudi Arabia. Founders German-born Charles Beyer had undertaken engineering training related to cotton milling in Dresden before moving to England in 1831 aged 21. He became draughtsman at Sharp, Roberts and Company's Atlas works in central Manchester, which manufactured cotton mill machinery and had just started building locomotives for the Liverpool and Manchester Railway. There he was mentored by head engineer and prolific inventor of cotton mill machinery Richard Roberts. By the time he resigned 22 years later he was well established as the company's head engineer; he had be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belpaire Firebox
The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today it generally refers to the shape of the outer shell of the firebox which is approximately flat at the top and square in cross-section, indicated by the longitudinal ridges on the top sides. However, it is the similar square cross-section inner firebox which provides the main advantages of this design i.e. it has a greater surface area at the top of the firebox where the heat is greatest, improving heat transfer and steam production, compared with a round-top shape. The flat firebox top would make supporting it against pressure more difficult (e.g. by means of girders, or stays) compared to a round-top. However, the use of a similarly shaped square outer boiler shell allows simpler perpendicular stays to be used between the shells. The Belpaire outer firebox is, nevertheless, more complicated and expensive to manufacture than a round-top version. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives Introduced In 1948
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19 ...

Passenger Locomotives
A passenger is a person who travels in a vehicle, but does not bear any responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle, and is not a steward. The vehicles may be bicycles, buses, cars, passenger trains, airliners, ships, ferryboats, personal watercraft, all terrain vehicles, snowmobiles, and other methods of transportation. Crew members (if any), as well as the driver or pilot of the vehicle, are usually not considered to be passengers. For example, a flight attendant on an airline would not be considered a passenger while on duty and the same with those working in the kitchen or restaurant on board a ship as well as cleaning staff, but an employee riding in a company car being driven by another person would be considered a passenger, even if the car was being driven on company business. Legal status In most jurisdictions, laws have been enacted that dictate the legal obligations of the owner of a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotives Of Ireland
A wide variety of steam locomotives have been used on History of rail transport in Ireland, Ireland's railways. This page lists most if not all those that have been used in the Republic of Ireland and Northern Ireland. Irish railways generally followed British practice in locomotive design. The list that follows is roughly geographic (north to south) order. Northern Ireland The Ulster Transport Authority, which controlled the railways in Northern Ireland between 1948 and 1966, replaced Steam locomotive, steam haulage on passenger trains with diesel multiple units, but had only two diesel shunting locomotives, which meant a continued role for steam on freight work. Twenty-three locomotives passed to Northern Ireland Railways in 1967, but most were not used again and all had been withdrawn by 1971. Belfast and County Down Railway The Belfast and County Down Railway was founded in 1848. It absorbed the Belfast, Hollywood and Bangor Railway in 1884 and continued operating until it w ...

Steam Locomotives Of Northern Ireland
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam". When liquid water becomes steam, it increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapour pressure, it can create a steam explosion. Types of steam and conversions Steam is trad ...

Smoke Deflectors
Smoke deflectors, sometimes called "blinkers" in the UK because of their strong resemblance to the Blinkers (horse tack), blinkers used on horses, and "elephant ears" in US railway slang, are vertical plates attached to each side of the smokebox at the front of a steam locomotive. They are designed to lift smoke away from the locomotive at speed so that the driver has better visibility. On the South Australian Railways 500 class (steam)#Rebuilding, South Australian Railways they are called "valances". Overview Smoke deflectors became increasingly common on later steam locomotives because the velocity of the smoke exiting the chimney (locomotive), chimney had been reduced as a result of efficiency gains obtained by improved smokebox design, such as the Kylchap exhaust and Giesl ejector, and as boilers became larger the size of the chimneys had to be reduced to maintain loading gauge. Styles Various styles of smoke deflectors have been used by different railway operators. Howe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNRI Class V
The Great Northern Railway V class steam locomotives were 4-4-0 three-cylinder compound locomotives built in 1932 by Beyer, Peacock & Company for the Great Northern Railway (Ireland). Design The V class was intended for the GNR's most important passenger service, the Dublin – Belfast expresses. The GNRI Class S, S and S2 Classes that had previously served the route were giving trouble as boiler pressure had been raised to increase power and performance. This increased maintenance (particularly with broken crank axles) and as a result the boiler pressure was brought back down. This obliged the GNR to develop a more powerful engine. George Glover designed the resultant 'V' class with on-site experience learnt from the design teams for the British LMS Compound 4-4-0 compound locomotives. The locomotives were ordered from Beyer, Peacock & Company and delivered in 1932. They cost £5,847, which was £3,000 less than the SG3 Class 0-6-0s built ten years before. Beyer, Peacock bu ...

4-4-0
4-4-0, in the Whyte notation, denotes a steam locomotive with a wheel arrangement of four leading wheels on two axles (usually in a leading bogie), four powered and coupled driving wheels on two axles, and no trailing wheels. First built in the 1830s, locomotives with this wheel arrangement were known as "standard" or "Eight-Wheeler" type. In the first half of the 19th century, almost every major railroad in North America owned and operated locomotives of this type, and many rebuilt their and locomotives as 4-4-0s.Kinert, Reed. (1962). ''Early American steam locomotives; 1st seven decades: 1830-1900''. Seattle, WA: Superior Publishing Company. In April 1872, '' Railroad Gazette'' used "American" as the name of the type. The type subsequently also became popular in the United Kingdom, where large numbers were produced.White, John H., Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''.
