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 ...

0-3-0
0-3-0 is a type of wheel arrangement for a monorail steam locomotive. History This most unusual wheel arrangement was only used for specialised monorails. Listowel and Ballybunion Railway The Lartigue Monorail locomotives used on the Listowel and Ballybunion Railway were of 0-3-0 wheel arrangement, although they also required non-load-bearing guide wheels. These locomotives were built by the Hunslet Engine Company, Leeds in 1888. Patiala State Monorail Trainways Four locomotives were built with this wheel arrangement in 1907 for the Patiala State Monorail Trainways, a monorail line in Patiala, India. They had double flanged driving wheels and the locomotives had an outrigger wheel that ran on the ground. The builder was Orenstein & Koppel of Berlin, one locomotive is preserved in working order at the National Rail Museum, New Delhi, New Delhi New Delhi (, , ''Naī Dillī'') is the capital of India and a part of the National Capital Territory of Delhi (NCT).

6-2-0
In the Whyte notation, a 6-2-0 is a railroad steam locomotive that has an unpowered three-axle leading truck followed by a single powered driving axle. This wheel arrangement is associated with the Crampton locomotive type, and in the USA the single class were sometimes referred to as ''Cramptons''. Other equivalent classifications are: UIC classification: 3A (also known as German classification and Italian classification) French classification: 310 Turkish classification: 14 Swiss classification: 1/4 History The 6-2-0 was a most unusual wheel arrangement, where the bulk of the locomotive's weight was on the unpowered leading wheels rather than the powered driving wheels, therefore giving poor adhesion. The type was only practicable on the Crampton locomotive with a low boiler and large driving wheels placed behind the firebox. United Kingdom The only British 6-2-0 was the locomotive ''Liverpool'' built in 1848 by Bury, Curtis, and Kennedy for the London and North Western Railw ...

4-2-4T
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle, and four trailing wheels on two axles. This type of locomotive is often called a Huntington type. The configuration was most often used for tank engines, which is noted by adding letter suffixes to the configuration, such as for a conventional side-tank locomotive, for a saddle-tank locomotive, for a well-tank locomotive and for a rack-equipped tank locomotive. Overview This wheel arrangement was mainly used on various tank locomotive configurations. Eight 4-2-4 well- and back-tank locomotives which entered service on the Bristol and Exeter Railway in 1853 appear to have been the first with this wheel arrangement. The engine was designed by James Pearson, the railway company's engineer, and featured single large flangeless driving wheels between two supporting four-wheeled bogies. The water was ...

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.

4-2-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle and no trailing wheels. This type of locomotive is often called a Jervis type, the name of the original designer. Overview The wheel arrangement type was common on United States railroads from the 1830s through the 1850s. The first to be built was the ''Experiment'', later named ''Brother Jonathan'', for the Mohawk and Hudson Railroad in 1832. It was built by the West Point Foundry based on a design by John B. Jervis. Having little else to reference, the manufacturers patterned the boiler and valve gear after locomotives built by Robert Stephenson of England. A few examples of Stephenson locomotives were already in operation in America, so engineers did not have to travel too far to get their initial ideas. In England, the was developed around 1840 from the 2-2-2 design of Stephenson's first Long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-2-4T
In Whyte notation, a 2-2-4T is a railroad steam locomotive that has two leading wheels followed by two coupled driving wheels and four trailing wheels. This was an unusual wheel arrangement, only used on a few specialised locomotives. Equivalent classifications Other equivalent classifications are: *UIC classification: 1A2 (also known as German classification and Italian classification) *French classification: 112 *Turkish classification: 14 *Swiss classification: 1/4 UK examples In the United Kingdom, the North Eastern Railway, had four tank locomotives of this wheel arrangement, all of which had previously been rebuilt from other types. They were: No. 66 ''Aerolite'' rebuilt as a 2-2-4T in 1902 and later known as in LNER class X1; No. 957, which had been rebuilt from a BTP class 0-4-4T in 1903 and later classified as X2 class. NER 190 Class, later class X3 had two members, Nos. 190 and 1679, both rebuilt from 2-2-2 tender locomotives. All four were inherited by the Lon ...

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 ...

2-2-0
Under Whyte notation for the classification of steam locomotives, 2-2-0 represents the wheel arrangement of two leading wheels on one axle, two powered driving wheels on one axle, and no trailing wheels. This configuration, which became very popular during the 1830s, was commonly called the Planet type after the first locomotive, Robert Stephenson's ''Planet'' of 1830. Equivalent classifications Other equivalent classifications are: *UIC classification: 1A (also known as German classification and Italian classification) *French classification: 110 *Turkish classification: 12 *Swiss classification: 1/2 History Great Britain After early experience with the 0-2-2 configuration on the Liverpool and Manchester Railway, Robert Stephenson decided to build a locomotive with cylinders inside the frames, for which a 2-2-0 was preferable. The first such locomotive was ''Planet'', built in 1830 and the company went on to build a further eighteen examples for the railway. In 1835 five e ...

0-2-4
Under the Whyte notation for the classification of steam locomotives, 0-2-4 represents the wheel arrangement of no leading wheels, two powered driving wheels on one axle, and four trailing wheels on two axles. History This is a most unusual wheel arrangement, with the only known examples being three locomotives supplied to the 4ft 6in Dundee and Newtyle Railway by J and C Carmichael of Dundee in 1833. These were still in operation in 1847, but may have been scrapped in 1849 when the line was converted to the standard gauge A standard-gauge railway is a railway with a track gauge of .

0-2-2
An 0-2-2, in the Whyte notation for the classification of steam locomotives by wheel arrangement, is one that has two coupled driving wheels followed by two trailing wheels, with no leading wheels. The configuration was briefly built by Robert Stephenson and Company for the Liverpool and Manchester Railway Equivalent classifications Other equivalent classifications are: *UIC classification: A1 (also known as German classification and Italian classification) *French classification: 011 *Turkish classification: 12 *Swiss classification: 1/2 Liverpool & Manchester Railway ''Rocket'' The 0-2-2 or ''Northumbrian'' wheel arrangement was first used for Stephenson's ''Rocket'', their entry for the Rainhill Trials of 1829, a competition to choose a locomotive design for the new Liverpool & Manchester Railway. Stephenson recognised that the rules of the competition favoured a fast, light locomotive of only moderate hauling power. Although George Stephenson's previous designs had b ...
