4-10-2
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, represents the arrangement of four leading wheels, ten powered and coupled driving wheels and two trailing wheels. In South Africa, where the wheel arrangement was first used, the type was known as a Reid Tenwheeler. In the United States of America it was known as a Southern Pacific on the Southern Pacific Railroad and as an Overland on the Union Pacific Railroad. Overview This wheel arrangement was first used on the Natal Government Railways (NGR) in the Colony of Natal in 1899, on a tank locomotive that was designed to meet the requirement for a locomotive that could haul at least one and a half times as much as an NGR Dübs A 4-8-2T locomotive. In the United States, a simple expansion (simplex) version of the type was used only on the Southern Pacific and Union Pacific Railroads. Baldwin Locomotive Works built an experimental compound expansion in 1926, but since the weight and leng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Class H 4-10-2T
The South African Railways Class H , introduced in 1899, was a steam locomotive from the pre-Union of South Africa, Union era in the Colony of Natal. Between 1899 and 1903, the Natal Government Railways placed 101 tank steam locomotives with a wheel arrangement in service. In 1912, after the establishment of the South African Railways, 93 of these Class C Reid Tenwheelers survived unmodified and were designated .Classification of S.A.R.

4-8-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels, eight powered and coupled driving wheels and two trailing wheels. This type of steam locomotive is commonly known as the Mountain type. Overview The Colony of Natal in South Africa and New Zealand were innovators of the Mountain wheel arrangement. The Natal Government Railways (NGR) placed in service the first tank engines with the 4-8-2 arrangement, and the NGR was also first to modify tender locomotives to use a 4-8-2 wheel arrangement. The New Zealand Railways Department (NZR) introduced the first tender locomotives designed and built as 4-8-2. In 1888, the Natal Government Railways placed the first five of its eventual one hundred Class D tank locomotives in service. The locomotive was designed by William Milne, the locomotive superintendent of the NGR from 1877 to 1896, and was built by Dübs & Company. This was the first known use o ...

Natal Government Railways
The Natal Government Railways (NGR) was formed in January 1877 in the Colony of Natal. In 1877, the Natal Government Railways acquired the Natal Railway Company for the sum of £40,000, gaining the line from the Point to Durban and from Durban to Umgeni. This move, inspired in part by the neighbouring Cape Prime Minister John Molteno's 1873 establishment of the Cape Government Railways, was intended to drive the extension of Natal's railways inland, towards the Drakensberg and eventually the Orange Free State. The Natal Government Railways also adopted the Cape gauge. The core line went from Durban to Volksrust, but reached Charlestown ( from the border of the South African Republic) in 1891 and was linked to the Witwatersrand in 1895. Other important lines were the one linking with the Orange Free State reaching Harrismith in 1892, as well as the North Coast and South Coast lines. In 1910, the Union of South Africa was formed and in 1912 the NGR combined with the other colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Pacific 5021
Southern Pacific 5021 is an SP-2 class 4-10-2 steam locomotive built in 1926 by ALCO at their Schenectady, New York, shops. It is the only member of this class of SP locomotives to be preserved, and it is one of only five three-cylinder locomotives preserved in North America. History The locomotive was built in 1926 by the American Locomotive Company, it was designed to haul mixed freight and passenger trains over the Sierra Nevada range between northern California and Nevada. Later in its career, No. 5021 was shifted to service in Oregon, where it remained until its retirement in 1955. Southern Pacific donated No. 5021 to the Railway and Locomotive Historical Society on March 8, 1956. In 1961, it was fired up and used for operation on the museum's spur line. However, the Southern Pacific did not like this, so they were forced to pull the tracks in 1963. Following this, No. 5021 was stored in the roundhouse of the Atchison, Topeka and Santa Fe Railway. While it was stored, a pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 class ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithi ...

Southern Pacific Railroad
The Southern Pacific (or Espee from the railroad initials- SP) was an American Railroad classes#Class I, Class I Rail transport, railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company. The original Southern Pacific began in 1865 as a land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad. The Southern Pacific legacy founded hospitals in San Francisco, Tucson, Arizona, Tucson, and Houston. In the 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This ...
