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 ...

Union Pacific 3985
Union Pacific 3985, also known as the "Challenger", is a four-cylinder simple articulated 4-6-6-4 "Challenger"-type steam locomotive built in July 1943 by the American Locomotive Company (ALCO) of Schenectady, New York, for the Union Pacific Railroad. No. 3985 is one of only two Challengers still in existence and the only one to have operated in excursion service. No. 3985 operated in revenue service until 1957. It was then stored in the roundhouse in Cheyenne, Wyoming, until 1975, when it was placed outdoors beside the Cheyenne depot. In March 1981, after a group of Union Pacific employees restored the locomotive to operating condition, it was placed into excursion service as part of the Union Pacific's heritage fleet and became the world's largest operational steam locomotive. Mechanical problems took it offline in 2010, after which it was stored at the Union Pacific's Steam Shops in Cheyenne. On May 1, 2019, the title of largest operational steam locomotive was passed ...

4-6-6-4
In Whyte notation, a 4-6-6-4 is a railroad steam locomotive that has four leading wheels followed by six coupled driving wheels, a second set of six driving wheels and four trailing wheels. 4-6-6-4's are commonly known as Challengers. Other equivalent classifications are: UIC classification: 2CC2 (also known as German classification and Italian classification) French classification: 230+032 Turkish classification: 35+35 Swiss classification: 3/5+3/5 The UIC classification is refined to (2'C)C2' for Mallet locomotives. Challengers were most common in the Union Pacific Railroad, but many other railroads ordered them as well. An expansion for the Union Pacific Challenger class was the Union Pacific Big Boy class, being a 4-8-8-4, instead of a 4-6-6-4. Today, the only Challenger locomotives that survive were both owned by Union Pacific. One such locomotive, Union Pacific 3985, was operated by the Union Pacific Railroad in excursion service from 1981 to 2010, when mechanical prob ...

Union Pacific 844
Union Pacific 844, also known as the "Living Legend", is a class " FEF-3" 4-8-4 "Northern" type steam locomotive owned and operated by the Union Pacific Railroad for its heritage fleet. Built in December 1944 by the American Locomotive Company (ALCO) of Schenectady, New York, No. 844 is one of four surviving FEF Series locomotives and the only one in operation. The locomotive operated in revenue service until 1959. It was stored while awaiting scrapping, along with the rest of the UP steam locomotive fleet. In 1960, railroad leaders recognized the benefits of having a steam program and retained No. 844 for special activities, the kernel of what has become the Union Pacific's heritage fleet. Today, it is one of UP's oldest serving locomotives and the only steam locomotive owned by a North American Class I railroad that has never been retired. History Revenue service In 1944, Union Pacific and the American Locomotive Company (ALCO) collaborated on the FEF-3, a class of 10 ...

Union Pacific FEF Series
The Union Pacific FEF Series consists of forty-five 4-8-4 " Northern" steam locomotive types built by the American Locomotive Company (ALCO) between 1937 and 1944 and operated by the Union Pacific Railroad until 1959. The 45 locomotives were the last steam locomotives built for the Union Pacific. They represented the apex of dual-service steam locomotive development; funds and research were being concentrated into the development of diesel-electric locomotives. Designed to burn coal, they were converted to run on fuel oil in 1946. They pulled a variety of passenger trains, such as the '' Overland Limited'', '' Los Angeles Limited'', '' Portland Rose'' and '' Challenger'', until diesel-electric locomotives took over passenger service. Many FEF Series locomotives were later reassigned to freight service during the last few years of their careers. Four FEF Series locomotives survive today, including No. 844, which remains in operational condition and now runs in excursion serv ...

Union Pacific Railroad
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second largest railroad in the United States after BNSF, with which it shares a duopoly on transcontinental freight rail lines in the Western, Midwestern and Southern United States. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Chicago and North Western Transportation Company, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1996, the Union Pacific merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Railroad. Th ...

Southern Pacific 4449
Southern Pacific 4449, also known as the Daylight, is the only surviving example of Southern Pacific Railroad's "GS-4" class of 4-8-4 "Northern" type steam locomotives and one of only two GS-class locomotives surviving, the other being " GS-6" 4460 at the National Museum of Transportation in St. Louis, Missouri. GS is an abbreviation of "General Service" or "Golden State," a nickname for California (where the locomotive was operated in regular service). The locomotive was built by Lima Locomotive Works in Lima, Ohio for the Southern Pacific in May 1941; it received the red-and-orange "Daylight" paint scheme for the passenger trains of the same name which it hauled for most of its service career. No. 4449 was retired from revenue service in 1956 and put into storage. In 1958, the Southern Pacific donated the locomotive to the City of Portland, Oregon. The City then put the locomotive on static display in Oaks Amusement Park, where it remained until 1974. After this, No. 4 ...

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 ...

Southern Pacific Class GS-4
The Southern Pacific GS-4 is a class of streamlined 4-8-4 "Northern" type steam locomotive operated by the Southern Pacific Railroad (SP) from 1941 to 1958. A total of twenty-eight were built by the Lima Locomotive Works, numbered 4430 through 4457. GS stands for "Golden State" or "General Service." History Unlike the GS-3, the GS-4 had a dual-headlight casing (the top headlight was a mars light) on the silver smokebox. Another change was the all-weather cab. It retained the skyline casing atop the boiler, skirting on the sides, an air horn to supplement the whistle, and teardrop classification lights. They carried the orange and red "Daylight" paint scheme. The GS-4s were passenger engines capable of , though timetable speed limit never exceeded (the maximum speed allowed in the Salinas Valley). Southern Pacific's premier passenger trains were pulled by GS-4s: the '' Coast Daylight'', '' San Joaquin Daylight'', ''Lark'', ''Cascade'', '' Golden State'', and the ''Sunset Limi ...

Dieselization
Dieselisation (US: dieselization) is the process of equipping vehicles with a diesel engine or diesel engines. It can involve replacing an internal combustion engine powered by petrol (gasoline) fuel with an engine powered by diesel fuel, as occurred on a large scale with trucks, buses, farm tractors, and building construction machinery after the Second World War. Alternatively it can involve replacing the entire plant or vehicle with one that is diesel-powered; the term commonly describes the generational replacement between the 1930s and the 1970s of railway steam locomotives with diesel locomotives, and associated facilities. Water transport The Two-stroke diesel engine for marine applications was introduced in 1908 and remains in use today. It is the most efficient prime mover to date, models such as the Wärtsilä-Sulzer RTA96-C offer a thermal efficiency of 50% and over 100,000 horsepowers. First steps towards conversions using diesel engines as means of propulsion (on s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
