4-2-2
Under the Whyte notation for the classification of steam locomotives, 4-2-2 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle, and two trailing wheels on one axle. Other equivalent classifications are: :UIC classification: 2A1 :French classification: 211 :Turkish classification: 14 :Swiss classification: 1/4 Like other steam locomotive types with single pairs of driving wheels, they were also known as singles. History The 4-2-2 configuration offered designers eight wheels to spread the weight of a larger locomotive, but prior to the bogies (invented in 1830s) becoming popular, created a long rigid wheelbase with limited adhesion. As a result, the type was relatively rare until the 1870s. The first steam locomotive made by Borsig of Berlin in 1841, the ''Borsig'' No 1, was a 4-2-2, but the company quickly reverted to the more common 2-2-2 configuration.

Bristol And Exeter Railway 4-2-2 Locomotives
The 20 Bristol and Exeter Railway 4-2-2 locomotives were broad gauge 4-2-2 express steam locomotives built for the Bristol and Exeter Railway by the Stothert and Slaughter in Bristol. The first entered service in 1849. The Bristol and Exeter Railway was amalgamated into the Great Western Railway on 1 January 1876 and eight 4-2-2s survived at this time, the last being withdrawn in 1889. Three of the infamous 4-2-4T locomotives were rebuilt by the Great Western Railway in 1877 as 4-2-2 tender locomotives.

GWR Iron Duke Class
The Great Western Railway Iron Duke Class 4-2-2 was a class of broad gauge steam locomotives for express passenger train work. History The prototype locomotive, ''Great Western'', was built as a 2-2-2 locomotive in April 1846, but was soon converted to a 4-2-2 arrangement, with the leading wheels set rigidly within the sandwich framing, rather than in a separate bogie. The remainder of the class entered service between April 1847 and July 1855. Locomotives of the Iron Duke class were fast for their time and were recorded reaching . They were used to haul the Flying Dutchman express train which, for several decades, was the world's fastest train. In 1852, the daily service from London Paddington to Exeter () was achieved with an average speed of , with the flatter section between London and Swindon covered at an average speed of . From about 1865, the Iron Duke Class was known as the Alma Class. In May to July 1870, three locomotives (''Great Britain'', ''Prometheus'' and ''E ...

LNWR 2-2-2 3020 Cornwall
London and North Western Railway (LNWR) 2-2-2 No. 3020 ''Cornwall'' is a preserved steam locomotive. She was built at Crewe in 1847. She was originally a 4-2-2 in 1847, but was extensively rebuilt, and converted to a 2-2-2 in 1858. Early high-speed locomotive design In the 1840s, express passenger locomotive design was focussed on the need for single large-diameter driving wheels of around . The wheel diameter is effectively the "gear ratio" of a steam engine, and large driving wheels delivered the high linear tyre speed needed for fast locomotives, whilst keeping the axle bearing and piston speeds low enough to remain within the limits of the existing technology. Later on, increasing engine power would require better adhesion than a single pair of driving wheels could provide, but that was not a problem at the time. As well as needing large wheels for speed, stability required a low centre of gravity, and thus a low-slung boiler. The difficulty was that the two conditions w ...

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] |
Great Northern Railway (England)
The Great Northern Railway (GNR) was a British railway company incorporated in 1846 with the object of building a line from London to York. It quickly saw that seizing control of territory was key to development, and it acquired, or took leases of, many local railways, whether actually built or not. In so doing, it overextended itself financially. Nevertheless, it succeeded in reaching into the coalfields of Nottinghamshire, Derbyshire and Yorkshire, as well as establishing dominance in Lincolnshire and north London. Bringing coal south to London was dominant, but general agricultural business, and short- and long-distance passenger traffic, were important activities too. Its fast passenger express trains captured the public imagination, and its Chief Mechanical Engineer Nigel Gresley became a celebrity. Anglo-Scottish travel on the East Coast Main Line became commercially important; the GNR controlled the line from London to Doncaster and allied itself with the North East ...

Avonside Engine Company
The Avonside Engine Company was a locomotive manufacturer in Avon Street, St. Philip's, Bristol, England between 1864 and 1934. However the business originated with an earlier enterprise Henry Stothert and Company. Origins The firm was originally started by Henry Stothert in 1837 as Henry Stothert and Company. Henry was the son of George Stothert (senior), founder of the nearby Bath engineering firm of Stothert & Pitt. Henry's brother, also named George, was manager of the same firm. The company was given an order for two broad gauge () Firefly class express passenger engines ''Arrow'' and ''Dart'', with driving wheels, delivered for the opening of the Great Western Railway (GWR) from Bristol to Bath on 31 August 1840. This was soon followed by an order for eight smaller Sun class engines with driving wheels. Stothert, Slaughter and Company Edward Slaughter joined the company in 1841, when it became known as Stothert, Slaughter and Company. By 1844 their works were n ...

Great Western Railway
The Great Western Railway (GWR) was a British railway company that linked London with the southwest, west and West Midlands of England and most of Wales. It was founded in 1833, received its enabling Act of Parliament on 31 August 1835 and ran its first trains in 1838 with the initial route completed between London and Bristol in 1841. It was engineered by Isambard Kingdom Brunel, who chose a broad gauge of —later slightly widened to —but, from 1854, a series of amalgamations saw it also operate standard-gauge trains; the last broad-gauge services were operated in 1892. The GWR was the only company to keep its identity through the Railways Act 1921, which amalgamated it with the remaining independent railways within its territory, and it was finally merged at the end of 1947 when it was nationalised and became the Western Region of British Railways. The GWR was called by some "God's Wonderful Railway" and by others the "Great Way Round" but it was famed as the "Holiday ...

Flangeless Driver
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunting locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets which are linked together within the set. Diameter Driving wheels are g ...

Daniel Gooch
Sir Daniel Gooch, 1st Baronet (24 August 1816 – 15 October 1889) was an English railway locomotive and transatlantic cable engineer. He was the first Superintendent of Locomotive Engines on the Great Western Railway from 1837 to 1864 and its chairman from 1865 until his death in 1889. Between 1865 and 1885 Gooch was Conservative MP for Cricklade. Early life Gooch was born in Bedlington, Northumberland, the son of John Gooch, an iron founder, and his wife Anna Longridge. In 1831 his family moved to Tredegar Ironworks, Monmouthshire, South Wales, where his father had accepted a managerial post, and it was there that Daniel would begin training under Thomas Ellis senior, who together with Ironmaster Samuel Homfray and Richard Trevithick pioneered steam railway locomotion. Gooch wrote in his diaries "Large works of this kind are by far the best school for a young engineer to get a general knowledge of what he needs in after life." and "...I look back upon the time spent at ...

2-2-2
Under the Whyte notation for the classification of steam locomotives, 2-2-2 represents the wheel arrangement of two leading wheels on one axle, two powered driving wheels on one axle, and two trailing wheels on one axle. The wheel arrangement both provided more stability and enabled a larger firebox than the earlier 0-2-2 and 2-2-0 types. This configuration was introduced in 1834 on Robert Stephenson's ' Patentee locomotive' but it was later popularly named Jenny Lind, after the Jenny Lind locomotive which in turn was named after the popular singer. They were also sometimes described as Singles, although this name could be used to describe any kind of locomotive with a single pair of driving wheels. Equivalent classifications Other equivalent classifications are: *UIC classification: 1A1 (also known as German classification and Italian classification) *French classification: 111 *Turkish classification: 13 *Swiss classification: 1/3 History The 2-2-2 configuration appears to ha ...

Wheel Arrangement
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered. Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. Major notation schemes The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC classificat ...
