French Locomotive Classification
Under the French classification system for locomotive wheel arrangements, the system is slightly different for steam and electric/diesel vehicles. Steam The French system counts axles, rather than wheels. As with Whyte notation, a conventional rigid locomotive will have three digits corresponding to its axle configuration: The first digit is the number of leading unpowered axles; the second digit the number of powered axles; The third digit the number of trailing unpowered axles. Examples 0-6-0 = 030 2-6-0 = 130 0-6-2 = 031 4-6-2 = 231 2-8-0 = 140 4-8-0 = 240 4-6-4 = 232 4-8-4 = 242 2-6-6-2 = 130+031 Electric and diesel With electric and diesel vehicles include Diesel Multiple Units, DMUs a letter A-B-C-D replaces 1-2-3-4 for the number of powered axles, and each bogie is grouped separately. 0-4-0+0-4-0 = B-B (if axles connected by rods or other means) 0-6-0+0-6-0 = Co-Co (if axles driven independently) See also * UIC classification Locomotive classifi ...

0-6-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and no trailing wheels. This was the most common wheel arrangement used on both tender and tank locomotives in versions with both inside and outside cylinders. In the United Kingdom, the Whyte notation of wheel arrangement was also often used for the classification of electric and diesel-electric locomotives with side-rod coupled driving wheels. Under the UIC classification, popular in Europe, this wheel arrangement is written as C if the wheels are coupled with rods or gears, or Co if they are independently driven, the latter usually being electric and diesel-electric locomotives. Overview History The 0-6-0 configuration was the most widely used wheel arrangement for both tender and tank steam locomotives. The type was also widely used for diesel switchers (shunters). Because they lack leading a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-6-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels. This arrangement is commonly called a Mogul. Overview In the United States and Europe, the wheel arrangement was principally used on tender locomotives. This type of locomotive was widely built in the United States from the early 1860s to the 1920s. Although examples were built as early as 1852–53 by two Philadelphia manufacturers, Baldwin Locomotive Works and Norris Locomotive Works, these first examples had their leading axles mounted directly and rigidly on the frame of the locomotive rather than on a separate truck or bogie. On these early 2-6-0 locomotives, the leading axle was merely used to distribute the weight of the locomotive over a larger number of wheels. It was therefore essentially an 0-8-0 with an unpowered leadin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
0-6-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The type is sometimes known as a Webb or a Branchliner. Overview While some locomotives with this wheel arrangement had tenders, the majority were tank locomotives which carried their coal and water onboard. Usage Finland Finland used two classes of 0-6-2T locomotive, the Vr2 and the Vr5. The Vr2 class was numbered in the range from 950 to 965. Five of them are preserved in Finland, no. 950 at Joensuu, no. 951 at Tuuri, no. 953 at Haapamäki, no. 961 at Jyväskylä and no. 964 at the Veturimuseo at Toijala. The Vr5 class was numbered in the range from 1400 to 1423. No. 1422 is preserved at Haapamäki. Philippines There were 30 ''Dagupan''-type locomotives built between 1889 and 1890. All were tank locomotives, weighed and were run a maximum speed of . These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific 231G 558-07juin2009-109
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

4-6-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The locomotive became almost globally known as a Pacific type. Overview The introduction of the design in 1901 has been described as "a veritable milestone in locomotive progress". On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric locomotive, electric or diesel locomotive, diesel-electric locomotives during the 1950s and 1960s. Nevertheless, new Pacific designs continued to be built until the mid-1950s. The type is generally considered to be an enlargement of the 4-4-2 (locomotive), Atlantic type, although its NZR Q class (1901), prototype had ...

2-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s ''Consolidation'', the name of the first 2-8-0.White, John H. Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York: Dover Publications, p. 65. The notation 2-8-0T indicates a tank locomotive of this wheel arrangement, the "T" suffix indicating a locomotive on which the water is carried in side-tanks mounted on the engine rather than in an attached tender. The Consolidation represented a notable advance in locomotive power. After 1875, it became "the most popular type of freight locomotive in the United States and was built in greater quantities than any other si ...

4-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Twelve-wheeler. Overview The first locomotive is believed to have been the ''Centipede'', a tender locomotive built by Ross Winans in 1855 for the Baltimore and Ohio Railroad in the United States of America, where it remained in service for nearly twenty years. It appears to have been delivered in a cab-forward type of configuration that was modified to a Camel configuration in 1864.Carling, D. Rock (1972). ''4-8-0 Tender Locomotives''. Drake Publishers Inc. On a Camel locomotive the cab was mounted atop the boiler, unlike the later Camelback locomotive whose cab straddled the boiler and that first appeared around 1877.

4-6-4
Under the Whyte notation for the classification of locomotives, represents the wheel arrangement of four leading wheels, six powered and coupled driving wheels and four trailing wheels. In France where the type was first used, it is known as the Baltic while it became known as the Hudson in most of North America. Overview Tender locomotives The 4-6-4 tender locomotive was first introduced in 1911 and throughout the 1920s to 1940s, the wheel arrangement was widely used in North America and to a lesser extent in the rest of the world. The type combined the basic design principles of the 4-6-2 type with an improved boiler and larger firebox that necessitated additional support at the rear of the locomotive. In general, the available tractive effort differed little from that of the 4-6-2, but the steam-raising ability was increased, giving more power at speed. The 4-6-4 was best suited to high-speed running across flat terrain. Since the type had fewer driving wheels than carryin ...

4-8-4
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern. Overview Development The wheel arrangement was a progression from the Mountain type and, like the Berkshire and Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which allowed greater production of steam. The four-wheel leading truck gave stability at speed and the eight driving wheels gave greater adhesion. The evolution to the type occurred in the United States of America soon after the Lima Lo ...

2-6-6-2
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a is a locomotive with one pair of unpowered leading wheels, followed by two sets of three pairs of powered driving wheels and one pair of trailing wheels. The wheel arrangement was principally used on Mallet-type articulated locomotives, although some tank locomotive examples were also built. A Garratt type locomotive with the same wheel arrangement is designated . Under the UIC classification the wheel arrangement is referred to as (1'C)C1' for Mallet locomotives. Overview The 2-6-6-2 wheel arrangement was most often used for articulated compound steam Mallet locomotives. In a compound Mallet, the rear set of coupled wheels are driven by the smaller high pressure cylinders, from which spent steam is then fed to the larger low pressure cylinders that drive the front set of coupled wheels. Compounding Steam Engines This type of locomotive was commonly used in North America on logging rail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Multiple Units
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UIC Classification
The UIC classification of locomotive axle arrangements, sometimes known as the German classification''The Railway Data File''. Leicester: Silverdale, 2000. p. 52. . or German system,Kalla-Bishop P.M. & Greggio, Luciano, ''Steam Locomotives'', Crescent, 1985, p. 226. describes the wheel arrangement of locomotives, multiple units and trams. It is used in much of the world, notable exceptions being the United Kingdom, which uses a slightly simplified form of UIC (except for steam locomotives and small diesel shunters, where Whyte notation is used), and in North America, where the AAR wheel arrangement system (essentially another simplification of the UIC system) is used to describe diesel and electric locomotives; Whyte notation is used in North America only for steam locomotives. The classification system is managed by the International Union of Railways (UIC). Structure The UIC uses the following structure: ; Upper-case letters : Indicate driving axles, starting at A for a singl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
