2-2-2-0
Under the Whyte notation for the classification of steam locomotives, 2-2-2-0 usually represents the wheel arrangement of two leading wheels on one axle, four powered but uncoupled driving wheels on two axles, and no trailing wheels, but can also be used to represent two sets of leading wheels (not in a bogie truck) two driving wheels, and no trailing wheels. Some authorities place brackets around the duplicated but uncoupled wheels, creating a notation 2-(2-2)-0, or (2-2)-2-0, as a means of differentiating between them. Others simply refer to the locomotives 2-2-2-0. Usage The 2-2-2-0 wheel arrangement was first used on some locomotives introduced on the Eastern Counties Railway by John Chester Craven between 1845 and 1847, and some Crampton locomotives on the South Eastern Railway in 1849.Baxter, (1977) pp.45 & 67. However the 2-2-2-0 type is usually associated with Francis Webb of the London and North Western Railway who between 1882 and 1890 introduced a number of compound ...

LNWR Dreadnought Class
The LNWR Dreadnought class was a class of 40 passenger three-cylinder compound 2-2-2-0 locomotives designed by F. W. Webb for the London and North Western Railway, and manufactured by them in their Crewe Works between 1884 and 1888. The railway also commissioned the Beyer, Peacock and Company to construct an additional locomotive of the design for the Pennsylvania Railroad.Nock, O. S., et al. Railways at the Turn of the Century, 1895-1905. Blandford P., 1969. Design The design featured a boiler pressed to delivering saturated steam to two outside high-pressure cylinders, which exhausted to one low-pressure cylinder inside the frames. All three cylinders had a stroke of ; the high-pressure cylinders drove the rear wheels, while the low-pressure drove the leading driving wheels. As the two pairs of driving wheels were not connected, the locomotives were " duplex drive" or "double-singles". They were a development of Webb's Experiment class; they had larger boilers and smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Webb (engineer)
Francis William Webb (21 May 1836 – 4 June 1906) was an English railway engineer, responsible for the design and manufacture of locomotives for the London and North Western Railway (LNWR). Webb was born in Tixall Rectory, near Stafford, the second son of William Webb, Rector of Tixall. Career Crewe Works Showing early interest in mechanical engineering, on 11 August 1851 at the age of fifteen he was articled as a pupil of Francis Trevithick at Crewe Works.Griffiths, p.51 Webb joined the drawing office in 1856, at the end of his training. He became Chief Draughtsman on 1 March 1859. On 1 September 1861 he was appointed Works Manager at Crewe and Chief Assistant to John Ramsbottom. Whilst Works Manager Webb was responsible for the installation of Bessemer converters and the start of steel production at Crewe. Bolton Iron and Steel Company In July 1866 Webb resigned from the LNWR and moved to the Bolton Iron and Steel Co. as the manager. It has been suggested that ...

LNWR Teutonic Class
The LNWR Teutonic class was a class of 10 passenger three-cylinder compound locomotive, compound 2-2-2-0 locomotives designed by F. W. Webb for the London and North Western Railway, and manufactured by them in their Crewe Works between 1889 and 1890. Design The design featured a boiler pressed to delivering saturated steam to two outside high-pressure cylinders, which exhausted to one low-pressure cylinder inside the frames. All three cylinders had a stroke of ; the high-pressure cylinders drove the rear wheels, while the low-pressure drove the leading driving wheels. As the two pairs of driving wheels were not connected, the locomotives were "duplex locomotive, duplex drive" or "double-singles". They were a development of Webb's LNWR Dreadnought Class, Dreadnought class; they had larger driving and leading wheels, and the additions of cylinder tail rods (which were later removed). There were also further modifications to the Joy valve gear, but the seven locomotives built i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Locomotive
A compound locomotive is a steam locomotive which is powered by a compound engine, a type of steam engine where steam is expanded in two or more stages. The locomotive was only one application of compounding. Two and three stages were used in ships, for example. Compounding became popular for railway locomotives from the early 1880s and by the 1890s were becoming common. Large numbers were constructed, mostly two- and four-cylinder compounds, in France, Germany, Austria, Hungary, and the United States. It declined in popularity due to maintenance issues and because superheating provided similar efficiencies at lower cost. Nonetheless, compound Mallets were built by the Norfolk and Western Railway right up to 1952. Introduction In the usual arrangement for a compound engine the steam is first expanded in one or two high-pressure ''(HP)'' cylinders, then having given up some heat and lost some pressure, it exhausts into a larger-volume low-pressure ''(LP)'' cylinder, (or two, - or ...

Eastern Counties Railway
The Eastern Counties Railway (ECR) was an English Rail transport, railway company incorporated in 1836 intended to link London with Ipswich via Colchester, and then extend to Norwich and Great Yarmouth, Yarmouth. Construction began in 1837 on the first nine miles at the London end. Construction was beset by engineering and other problems, leading to severe financial difficulties. As a result, the project was truncated at Colchester in 1843 but through a series of acquisitions (including the Eastern Union Railway who completed the link between Colchester and Norwich) and opening of other lines, the ECR became the largest of the East Anglian railways. In 1862 ECR was merged with a number of other companies to form the Great Eastern Railway. Opening In 1835 a surveyor called Henry Sayer presented a plan for a new railway from London to York via Cambridge to London solicitors Dimes & Boyman. Together with John Clinton Robertson who was to become the first secretary of the ECR and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LNWR Webb Experiment Class
The London and North Western Railway ''Experiment'' Class was a series of 30 three-cylinder 2-(2-2)-0 compound locomotives designed by Francis Webb for the London and North Western Railway between 1882 and 1884. They were Webb’s first large-scale experiment with a class of express compound locomotives, and the first engine was named accordingly. They were followed by a class of similar, but larger locomotives, that featured larger boilers and smaller driving wheels – the LNWR Dreadnought Class. After Webb's retirement, his successor, George Whale, withdrew the ''Experiment'' class locomotives soon after he took up office in 1903. Accidents and incidents : *On 22 December 1894, a gust of wind blew a wagon into a rake of wagons at , Cheshire. They were derailed and fouled the main line. Locomotive No. 520 ''Express'' was one of two hauling an express passenger train that collided with the wagons and was derailed. 14 people were killed and 48 were injured. Locomotives Ref ...

London And North Western Railway
The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. In the late 19th century, the L&NWR was the largest joint stock company in the United Kingdom. In 1923, it became a constituent of the London, Midland and Scottish (LMS) railway, and, in 1948, the London Midland Region of British Railways: the LNWR is effectively an ancestor of today's West Coast Main Line. History The company was formed on 16 July 1846 by the amalgamation of the Grand Junction Railway, London and Birmingham Railway and the Manchester and Birmingham Railway. This move was prompted, in part, by the Great Western Railway's plans for a railway north from Oxford to Birmingham. The company initially had a network of approximately , connecting London with Birmingham, Crewe, Chester, Liverpool and Manchester. The headquarters were at Euston railway station. As traffic increased, it was greatly expanded with the opening in 1849 of the Great Hall, designed by P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-2-2-0
Under the Whyte notation for the classification of steam locomotives, 4-2-2-0 represents the wheel arrangement of four leading wheels on two axles, four powered but uncoupled driving wheels on two axles, and no trailing wheels. The arrangement became known as ''double single''. Usage This very unusual wheel arrangement was first used 1893 by ''Frederick Charles Winby'' for the locomotive ''James Toleman'', built by Hawthorn Leslie & Company. It was exhibited at the World’s Columbian Exposition in Chicago and then delivered to the Milwaukee Road. Between 1897 and 1901 Dugald Drummond of the London and South Western Railway used this wheel arrangement on two classes of divided drive locomotives, the T7 and E10 classes. The absence of coupling rods enabled the driving wheels to be more widely spaced than on a 4-4-0 locomotive and permitted the inclusion of a larger firebox Firebox may refer to: *Firebox (steam engine), the area where the fuel is burned in a steam engine *Firebo ...

Société Alsacienne De Constructions Mécaniques
The Société Alsacienne de Constructions Mécaniques (the Alsatian Corporation of Mechanical Engineering), or SACM, is an engineering company with its headquarters in Mulhouse, Alsace, which produced railway locomotives, textile and printing machinery, diesel engines, boilers, lifting equipment, firearms and mining equipment. SACM also produced the first atomic reactor at Marcoule. History Foundation The company was founded by André Koechlin in 1826 to produce textile machinery. In 1839, he opened a factory to build railway locomotives at Mulhouse in Alsace. The business grew rapidly but in 1871, the annexation of Alsace-Lorraine by Germany, brought about the transfer of some production to Belfort in France. In 1872 the company merged with the Graffenstaden company of Illkirch-Graffenstaden (a suburb of Strasbourg) to form SACM. Alsthom The new company diversified into the production of boilers, steel equipment, printing equipment, compressors, firearms and other engineerin ...

Alfred De Glehn
Alfred George de Glehn (15 September 1848 – 8 June 1936) was a notable English-born French designer of steam locomotives and an engineer with the Société Alsacienne de Constructions Mécaniques (SACM). His steam engines of the 1890s combined elegance, high speed, and efficiency. De Glehn's express locomotives were first used on the Nord Railway and on the boat trains from Calais to Paris, where they impressed passengers with their speed. He invented the Glehn system of compounding, and De Glehn types were built in large numbers in France, and were also built in smaller numbers in Belgium, Germany, New Zealand, and Russia, see Compound locomotive. Compounding lost favour from the 1900s, being replaced by superheating. However André Chapelon rebuilt many of the French De Glehn compounds from 1929 onwards. Personal life Alfred De Glehn was one of the twelve children of Robert von Glehn, a Prussian nobleman originally from the Baltic provinces, whose family had estates near Tall ...

George Whale
George Whale (7 December 1842 – 7 March 1910) was an English locomotive engineer who was born in Bocking, Essex, and educated in Lewisham, London. He worked for the London and North Western Railway (LNWR). Career In 1858 he entered the LNWR's Wolverton Works under James Edward McConnell, and when in 1862 the LNWR Board decided to concentrate locomotive construction and repair at Crewe Works under John Ramsbottom, Whale was one of around 400 workers transferred from Wolverton to Crewe. In 1865 he entered the drawing office at Crewe Works, and in 1867 joined the LNWR running department under J. Rigg. In 1898 he was made responsible for the running of all LNWR locomotives. Francis William Webb, the LNWR Locomotive Superintendent, gave twelve months notice of retirement to the LNWR Board in November 1902. On 22 April 1903, the Board announced that Whale had been chosen to succeed Webb, who was to retire at the end of July 1903. Webb's health was failing, and Whale soon took up ...

Whyte Notation
Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in ''American Engineer and Railroad Journal''. The notation was adopted and remains in use in North America and the United Kingdom to describe the wheel arrangements of steam locomotives (in the latter case also for diesel and electric locomotives), but for modern locomotives, multiple units and trams it has been supplanted by the UIC system in Europe and by the AAR system (essentially a simplification of the UIC system) in North America. Structure of the system Basic form The notation in its basic form counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers being separated by dashes. For example, a locomotive with two leadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
