Union Pacific Big Boy
The Union Pacific Big Boy is a type of simple articulated locomotive, articulated 4-8-8-4 steam locomotive manufactured by the American Locomotive Company (ALCO) between 1941 and 1944 and operated by the Union Pacific Railroad in revenue service until 1962. The 25 Big Boy locomotives were built to haul Rail freight transport, freight over the Wasatch Range between Ogden, Utah, and Green River, Wyoming. In the late 1940s, they were reassigned to Cheyenne, Wyoming, where they hauled freight over Sherman Hill Summit, Sherman Hill to Laramie, Wyoming. They were the only locomotives to use a 4-8-8-4 wheel arrangement: four-wheel leading truck for stability entering curves, two sets of eight driving wheels and a four-wheel trailing truck to support the large Firebox (steam engine), firebox. Today, eight Big Boys survive, with most on static display at museums across the United States. One of them, Union Pacific 4014, No. 4014, was re-acquired by Union Pacific, and between 2014 and 2019 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Pacific 4014
Union Pacific 4014 is a preserved 4884-1 class 4-8-8-4 "Union Pacific Big Boy, Big Boy" type steam locomotive owned and operated by the Union Pacific (UP) as part of Union Pacific Heritage Fleet, its heritage fleet. Built in November 1941 by American Locomotive Company (ALCO) in Schenectady, New York, it was assigned to haul heavy rail freight transport, freight trains in the Wasatch Range, Wasatch mountain range. The locomotive was retired from revenue service on December 7, 1961, and was donated to the Railroad History, Railway & Locomotive Historical Society; thereafter, it was displayed in Fairplex at the RailGiants Train Museum in Pomona, California. In 2013, UP re-acquired the locomotive and launched a restoration project at its Steam Shop in Cheyenne, Wyoming. In May 2019, No. 4014 moved under its own power after sitting dormant for almost six decades, becoming the world's largest operational steam locomotive and the only operating Big Boy locomotive of the eight that rem ...

American Locomotive Company
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants. The company was formed by the merger of seven locomotive manufacturers and Schenectady Locomotive Works, 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. After World War II, Alco closed all of its manufacturing plants except those in Schenectady and Montreal. In 1955, the company changed its name to Alco Products, Incorporated. In 1964, the Worthington Corporation acquired the company. The company wen ... [...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 classifi ...

Adhesion Railway
An adhesion railway relies on adhesion traction to move the train, and is the most widespread and common type of railway in the world. Adhesion traction is the friction between the drive wheels and the steel rail. Since the vast majority of railways are adhesion railways, the term ''adhesion railway'' is used only when it is necessary to distinguish adhesion railways from railways moved by other means, such as by a stationary engine pulling on a funicular, cable attached to the cars or by a pinion meshing with a rack railway, rack. The friction between the wheels and rails occurs in the wheel–rail interface or contact patch. The traction force, the braking forces and the centering forces all contribute to stable running. However, running friction increases costs, due to higher fuel consumption and increased maintenance needed to address fatigue (material), fatigue damage and wear on rail heads and on the wheel rims and rail movement from traction and braking forces. Variation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Age
''Railway Age'' is an American trade magazine for the rail transport industry. It was founded in 1856 in Chicago (the United States' major railroad hub) and is published monthly by Simmons-Boardman Publishing Corporation. History The magazine's original title was the ''Western Railroad Gazette,'' and it was renamed the '' Railroad Gazette'' in 1870. In June 1908, after purchasing its chief rival, ''The Railway Age'' (founded in 1876 in Chicago), it changed its title to ''Railroad Age Gazette'', then in January 1910, to ''Railway Age Gazette''. In 1918, it shortened its name to the current title. ''Railway Review'' (originally the ''Chicago Railway Review'') was merged into ''Railway Age'' in 1927. Publications that have been merged into ''Railway Age'' include ''American Railroad Journal'', founded in 1832, renamed ''The Railroad and Engineering Journal'' in 1887 by its then-new owner/editor, Matthias N. Forney. It became ''American Engineer & Railroad Journal'' in 1883, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2-8-8-0
In the Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-8-8-0 is a locomotive with a two-wheel leading truck, two sets of eight driving wheels, and no trailing truck. Equivalent classifications Other equivalent classifications are: *UIC classification: 1DD (also known as German classification and Italian classification) *French classification: 140+040 *Turkish classification: 45+44 *Swiss classification: 4/5+4/4 The UIC classification is refined to (1'D)D for Mallet locomotives. Usage United States The Great Northern Railway (U.S.), Great Northern Railway used the 2-8-8-0s as their N-1's which were built by Baldwin in 1912. They were rebuilt by GN in 1932 as a N-2, and later re-rebuilt in 1940 as an N-3, The locomotives, after their third rebuild into a N-3, had a larger boiler and bigger tender. The N-3's served on the GN for a collective 45 years (including previous service lives as N-1 and N-2 classes), in use until retired in 1957. The U ...

Double Heading
In railroad terminology, double heading indicates the use of two locomotives at the front of a train, each operated individually by its own crew. The practice of triple-heading involves the use of three locomotives. The practice of multi-heading involves the use of multiple locomotives and so on. Double heading is most common with steam locomotives, but is also practised with diesel locomotives. It is not strictly the same practice as two or more diesel or electric locomotives working ' in multiple' (or 'multiple-working'), where both (or all) locomotives are controlled by a single driver in the cab of the leading locomotive. Advantages Double heading is practised for a number of reasons: * In the UK it was usually to gain traction on steep inclines, twice the amount of driven wheels – twice the amount of grip. * The need for additional motive power when a single locomotive is unable to haul the train due to uphill grades, excessive train weight, or a combination of the tw ...

Grade (slope)
The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal plane, horizontal or its tangent. It is a special case of the slope, where zero indicates horizontal plane, horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, bank (geography), stream and river banks, and stream bed, beds are often described as grades, but typically the word "grade" is used for human-made surfaces such as roads, landscape grading, roof pitches, rail tracks, railroads, aqueduct (watercourse), aqueducts, and pedestrian or bicycle routes. The grade may refer to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overland Route (Union Pacific Railroad)
The Overland Route was a train route operated jointly by the Union Pacific Railroad and the Central Pacific Railroad/Southern Pacific Railroad, between the eastern termini of Council Bluffs, Iowa, and Omaha, Nebraska, and the San Francisco Bay Area, over the grade of the first transcontinental railroad (also called the ''"Pacific Railroad"'') which opened on May 10, 1869. Passenger trains that operated over the line included the ''Overland Flyer'', later renamed the Overland Limited (UP train), ''Overland Limited'', with its eastern terminal in Chicago. The Overland Route remains a common name for the line from northern California to Chicago, now owned entirely by the Union Pacific. The route is now primarily used for freight, with a few portions used by Amtrak, Amtrak's ''California Zephyr'' passenger train. History The name harkens back to the Central Overland Route, a stagecoach line operated by the ''Overland Mail Company'' between Salt Lake City, Utah, and Virginia ...

4-6-6-4
In the Whyte notation for classifying steam locomotives by wheel arrangement, a 4-6-6-4 is a railroad steam locomotive that has four leading wheels followed by two sets of six coupled driving wheels and four trailing wheels. 4-6-6-4's are commonly known as Challengers. A similar wheel arrangement exists for Garratt locomotives, on which both engine units swivel, but is referred to as 4-6-0+0-6-4. 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 simple articulated 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 The Union Pacific Big Boy is a type of simple articulated locomotive, articulated 4-8-8 ...
