4-14-4
The SZD Class AA20 was a one-off experimental 4-14-4 steam locomotive constructed in the Soviet Union by Krupp and the Voroshilovgrad Locomotive Factory in 1934 for the Sovetskie Zheleznye Dorogi (SŽD). Two locomotives were set to be built, but due to the construction of the railway's more powerful FD Class, only AA20-1 was built, leaving the second AA20 incomplete. Wheel arrangement The AA20 was a "4-14-4" (Russian notation: 2-7-2) locomotive (using the Whyte notation classification of steam locomotives by wheel arrangement). It featured four leading wheels, fourteen coupled driving wheels (seven axles) in a rigid frame, and four trailing wheels. Equivalent classifications in other notations would have been: * AAR classification: 4-G-4 *UIC classification: 2G2 (also known as German classification and Italian classification) *French classification: 272 * Turkish classification: 711 * Swiss classification: 7/11 * Russian classification: 2-7-2 History Prerequisites for ...

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 ...

Andrey Andreyevich Andreyev
Andrey Andreyevich Andreyev (; 30 October 1895 – 5 December 1971) was a Communist Party of the Soviet Union, Soviet Communist politician. An Old Bolshevik who rose to power during the rule of Joseph Stalin, joining the Politburo as a candidate member in 1926 and as a full member in 1932, Andreyev also headed the powerful Central Control Commission of the Communist Party of the Soviet Union from 1930 to 1931, and then again from 1939 until 1952. In 1952, Andreyev was removed from the Politburo and placed in a largely ceremonial position as a member of the Presidium of the Supreme Soviet, Presidium of the Supreme Soviet. Biography Early years Andrey Andreyevich Andreyev was born in the Sychyovsky Uyezd of the Smolensk Governorate of the Russian Empire to a peasant family. He left the village at the age of 13 to work as a dishwasher in Moscow. He attended workers' educational courses, and by the time he was 15 had joined a Marxist circle. He joined the Communist Party of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driving Wheel
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 shunter locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets with wheels within each set linked together. Diameter Drivin ...

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 classifi ...

0-10-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of no leading wheels, ten powered and coupled driving wheels on five axles and no trailing wheels. In the United Kingdom, this type is known as a Decapod, a name which is applied to types in the United States. In the United States, the type is known as ten-coupled. Overview The lack of leading and trailing wheels makes this wheel arrangement unstable at speed, and it is a type usually confined to fairly low-speed work, such as switcher, switching (shunting), transfer runs, slow-speed drag freight, or running over mountainous terrain. The Russian E class was the most numerous single class of locomotive in the world, with around 11,000 manufactured. Usage Austria In 1899, Karl Gölsdorf introduced his famous 180.00 class for the Austrian State Railway, an 0-10-0 for mountain regions which had a remarkably low axle load. It employed the Gölsdorf axle system and had the driv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turkish Classification
In the Turkish classification system for railway locomotives, the number of powered axles are followed by the total number of axles. It is identical to the Swiss system except that the latter places a slash between the two numbers. Thus 0-6-0 becomes 33 4-6-2 becomes 36 2-6-4 becomes 36 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. ... becomes 45 See also * UIC classification system Locomotive classification systems Locomotives of Turkey {{europe-rail-transport-stub ...

Swiss Classification
For more than a century, the Swiss locomotive, multiple unit, motor coach and railcar classification system, in either its original or updated forms, has been used to name and classify the rolling stock operated on the railways of Switzerland. It started out as a uniform system for the classification and naming of all rolling stock, powered and unpowered, but had been replaced and amended by the UIC classification of goods wagons. Overview and evolution The Swiss classification system was created by the Swiss federal railways department, and applied originally to the rolling stock of private railways, operating under government concessions. In 1902, when the Swiss Federal Railways was founded as a government railway, that new railway also became bound by the system. Unlike the Whyte notation and AAR wheel arrangement, AAR system, both of which are used to classify wheel arrangements, and the UIC classification of locomotive axle arrangements, the Swiss system, in both its or ...

2-10-0
Under the Whyte notation for the classification of steam locomotives, 2-10-0 represents the wheel arrangement of two leading wheels on one axle, ten powered and coupled driving wheels on five axles, and no trailing wheels. This arrangement was often named Decapod, especially in the United States, although this name was sometimes applied to locomotives of 0-10-0 "Ten-Coupled" arrangement, particularly in the United Kingdom. Notable German locomotives of this type include the war locomotives of DRB Class 52, Class 52. These locomotives were popular in Europe, particularly in Germany and Russia; United Kingdom, British use of the type was confined to the period during and after World War II. In the United States, the 2-10-0 was not widely popular but was a favorite of a small number of railroads which operated mostly in mountainous terrain. Among these was the Erie Railroad, a major Chicago to New York trunk line railroad, and the Pennsylvania Railroad, whose heavily graded routes c ...

Italian 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 and North America. 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 single axle. B thus indicates two and C indicates three consecutive pairs of driving wheels. ; Lower-case "o" : Related to driving axles (minimum 2, "B"), indicates they are individually driven by separate traction motors. ; Numbers : Consecutive non-driving axles, starting with 1 for a single axle. ; Prime symbol " ′ " : The axles indicated by a single ...

Russian Locomotive Class Ye
The Russian locomotive class Ye, and subclasses Yea, Yek, Yel, Yef, Yem, Yemv and Yes (Russian: Паровоз Е; Еа, Ек, Ел, Еф, Ем, Емв and Ес) were a series of 2-10-0 locomotives built by American builders for the Russian railways in World War I and again in World War II. They were lightweight engines with relatively low axle loadings. Due to the Bolshevik revolution in 1917, 200 locomotives were stranded in the United States so these were fitted with wider tires: locomotive driving wheels had steel tires which were heated to expand them, then driven over the wheels so that they shrank into place. By fitting wider tires with a deeper tread width, the effective wheel gauge could be decreased from the Russian standard of to (the US standard) to fit the American gauge, and could then be sent to various railroads. The locomotives were nicknamed "Russian Decapods." A number of locomotives were acquired by the Finnish railways (class Tr2) and by the China Railway ( ...

2-12-0
Under the Whyte notation for the classification of steam locomotives, 2-12-0 represents the wheel arrangement of two leading wheels on one axle (usually in a leading truck), twelve powered and coupled driving wheels on six axles, and no trailing wheels. Equivalent classifications Other equivalent classifications are: *UIC classification: 1F (also known as German classification and Italian classification) *French classification: 160 * Turkish classification: 67 * Swiss classification: 6/7 Germany While standard German freight train steam locomotives were 2-10-0 types, between 1917 and 1924 the Esslingen locomotive works produced 44 units of the so-called Class K for the Royal Württemberg State Railways (later renumbered to class 59 by the Deutsche Reichsbahn). With a top speed of only 60 km/h these locomotives were designed for heavy duty in mountainous areas such as the Geislinger Steige, with special attention on low load per axle (16 t).
