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 4-8-2, Mountain type and, like the 2-8-4, Berkshire and 4-6-4, Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger Firebox (steam engine), 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 ...

Victorian Railways H Class
The Victorian Railways H class was an express passenger steam locomotive operated by the Victorian Railways from 1941 to 1958. Intended to eliminate the use of double heading A2 class locomotives on ''The Overland'' services on the steeply graded Western line to Adelaide, wartime restrictions led to only one locomotive being built. Nicknamed ''Heavy Harry'', H220 was the largest locomotive ever built in Australia and the largest non-articulated steam locomotive to run on Australian railways. History By 1923, the A2 class 4-6-0 locomotives, which dated back to 1907, were frequently double-heading on interstate expresses to Serviceton and Albury, because increasing traffic saw loads exceed the eight-car maximum of a single A2. The Victorian Railways Commissioners recommended considerably more powerful locomotives, that could haul trains of up to eleven cars unassisted over the ruling gradients on those lines. The S class 4-6-2 Pacifics displaced the A2s from North East lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Fe 3751
Atchison, Topeka & Santa Fe 3751 is a class 3751 4-8-4 steam locomotive built in 1927 by the Baldwin Locomotive Works in Eddystone (Philadelphia), Pennsylvania for the Atchison, Topeka & Santa Fe Railway (ATSF). 3751 was the first 4-8-4 steam locomotive built for the Santa Fe and was referenced in documentation as type: "Heavy Mountain", "New Mountain", or "Mountain 4-wheel trailer". No. 3751 served in passenger duties until being retired in 1953. The locomotive was then placed on display in San Bernardino until it was restored to operating condition in 1991. It is currently located in the Central City East neighborhood of Los Angeles and has been listed on the National Register of Historic Places since 2000. It holds the distinction of being the oldest surviving 4-8-4 type steam locomotive in the world. The locomotive is currently owned and operated by the San Bernardino Railroad Historical Society, which uses the locomotive to haul occasional mainline excursion trains. However ...

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 Trevith ...

Atchison, Topeka And Santa Fe Railway
The Atchison, Topeka and Santa Fe Railway , often referred to as the Santa Fe or AT&SF, was one of the larger railroads in the United States. The railroad was chartered in February 1859 to serve the cities of Atchison, Kansas, Atchison and Topeka, Kansas, and Santa Fe, New Mexico. The railroad reached the Kansas–Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by United States Congress, Congress. Despite being chartered to serve the city, the railroad chose to bypass Santa Fe, due to the engineering challenges of the mountainous terrain. Eventually Santa Fe Southern Railway, a branch line from Lamy, New Mexico, brought the Santa Fe railroad to its namesake city. The Santa Fe was a pioneer in intermodal freight transport; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the fleet of Santa Fe Railroad Tugboa ...

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 lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timken 1111
Timken 1111, also called the Timken Four Aces, was a 4-8-4 steam locomotive built in 1930 by American Locomotive Company (Alco) as a demonstration unit for new roller bearings produced by the Timken Roller Bearing Company. It was the first locomotive built with all sealed roller bearings rather than plain bearings or a combination of the two. It was later operated by the Northern Pacific Railroad as their 2626. Timken attempted to cooperate with Northern Pacific Railroad at the end of the engine's career to preserve it and while the Northern Pacific was willing to cooperate in preserving the engine, the attempt ultimately failed and the engine was scrapped in 1958. Design and construction Timken chose a 4-8-4 on which to demonstrate the company's roller bearings so the locomotive could be used in all types of railroad work, especially on heavy freight and fast passenger trains. 52 manufacturers agreed to supply parts for the locomotive "on account" until the locomotive operated ...

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 of the w ...

American Locomotive Company
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller locomotive manufacturers and Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969. The ALCO name is currently being used by Fairbanks Morse Engine for their FM, ALCO line. Foundation and early history The company was created in 1901 from the merger of seven smaller locomotive manufacturers with Schenectady Locomotive Engine Manufactory of Schenectady, New York: * Brooks Loco ...

DRB Class 06
The German DRB Class 06 engines were standard steam locomotives ('' Einheitsdampflokomotiven'') with the Deutsche Reichsbahn (DRB) designed to haul express train services. They were the only German locomotives with a 4-8-4 (Northern) wheel arrangement. History The two Class 06 locomotives built by the firm of Krupp in 1939 were the largest, heaviest and most powerful locomotives in the Deutsche Reichsbahn. They were built for heavy express train duties in hilly terrain. The performance requirement was for the transportation of 650 tons at 120 km/h. On ramps of 1:100 it was to still be capable of maintaining 60 km/h. The Class 06 was given the same boiler as the Class 45 and many of the same components as the Class 41. The running gear, with four coupled axles, had a wheelbase of 6,75 m. In trials, the vehicles confirmed their remarkable capability and running qualities. However the locomotives tended to derail in tight turnout curves. And, like the Class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lima Locomotive Works
Lima Locomotive Works was an American firm that manufactured railroad locomotives from the 1870s through the 1950s. The company took the most distinctive part of its name from its main shop's location in Lima, Ohio. The shops were located between the Erie Railroad main line, the Baltimore & Ohio's Cincinnati-Toledo main line and the Nickel Plate Road main line and shops. The company is best known for producing the Shay geared logging-steam locomotive, developed by Ephraim Shay, and for William E. Woodard's "Super Power" advanced steam locomotive concept – exemplified by the prototype 2-8-4 Berkshire, Lima demonstrator A-1. In World War II the Lima plant produced the M4A1 version of the M4 Sherman tank. History In 1878 James Alley contracted the Lima Machine Works to build a steam locomotive that Ephraim Shay had designed. In April 1880, Lima rebuilt Ephraim Shay's original design, using vertically side-mounted pistons mounted on the right, connected to a drive ...

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 classific ...

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 ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
