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) 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, UK, South Eastern Railway in 1849. However the 2-2-2-0 type is usually associated with Francis Webb (engineer), Francis Webb of the London and North Western Railway who between 1882 and 1890 introduced a n ...

LNWR Dreadnought Class
The LNWR Dreadnought class was a class of 40 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 1884 and 1888. The railway also commissioned the Beyer, Peacock and Company to construct an Pennsylvania Railroad no. 1320, 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 locomotive, duplex drive" or "double-singles". They were a devel ...

LNWR Teutonic Class
The LNWR Teutonic class was a class of 10 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 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 drive" or "double-singles". They were a development of Webb's 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 in 1890 had the inside cylinder worked by slip-eccentric valv ...

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). As the LNWR's chief mechanical engineer, he also exercised great influence in political and public life in the Cheshire town of Crewe, once being described as the 'King of Crewe'. Early life 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 star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Locomotive
A compound locomotive is a steam locomotive which is powered by a compound steam engine, 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 Germany, Austria, Hungary, and the United States. It declined in popularity due to a perceived increased maintenance requirement. Nonetheless, compound Mallets were built by the Norfolk and Western Railway up to 1952 and more importantly, Compound locomotives continued to be designed and built in France until the end of steam in the 1970's. French compounding of railway engines became so highly developed, eventually incorporating reheaters between the high and low pressure stages as well as the initial use of superh ...

Eastern Counties Railway
The Eastern Counties Railway (ECR) was an English railway company incorporated in 1836 intended to link London with Ipswich via Colchester, and then extend to Norwich and Yarmouth. Construction began in 1837 on the first 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 engineers John Braithwaite it was concl ...

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 Re ...

Whyte Notation
The 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, 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. However, geared steam locomotives do not use the notation. They are classified by their model and their number of trucks. 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 ...

Bogie
A bogie ( ) (or truck in North American English) comprises two or more Wheelset (rail transport), wheelsets (two Railroad wheel, wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly (trailer), dolly in a road train or in railway bogie exchange). It may include Suspension (vehicle), suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of continuous track, tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. Rail ...

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 railway works, 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 (engineer), 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. ...
