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 USA. One of them, Union Pacific 4014, No. 4014, was re-acquired by Union Pacific, and between 2014 to 2019 it was reb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Pacific 4014
Union Pacific 4014, also known as the "Big Boy", is a steam locomotive owned and operated by the Union Pacific Railroad (UP) as part of their heritage fleet. It is a four-cylinder simple articulated 4-8-8-4 " Big Boy" type built in 1941 by the American Locomotive Company (ALCO) at its Schenectady Locomotive Works. It was assigned to haul heavy freight trains in the Wasatch mountain range. The locomotive was retired from revenue service in 1959 and was donated to the Railway and 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 their Steam Shop in Cheyenne, Wyoming. In May 2019, No. 4014 moved under its own power for the first time 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 remain in existence.

Laramie, Wyoming
Laramie is a city in and the county seat of Albany County, Wyoming, United States. The population was estimated 32,711 in 2019, making it the third-largest city in Wyoming after Cheyenne and Casper. Located on the Laramie River in southeastern Wyoming, the city is north west of Cheyenne, at the junction of Interstate 80 and U.S. Route 287. Laramie was settled in the mid-19th century along the Union Pacific Railroad line, which crosses the Laramie River at Laramie. It is home to the University of Wyoming, WyoTech, and a branch of Laramie County Community College. Laramie Regional Airport serves Laramie. The ruins of Fort Sanders, an army fort predating Laramie, lie just south of the city along Route 287. Located in the Laramie Valley between the Snowy Range and the Laramie Range, the city draws outdoor enthusiasts with its abundance of outdoor activities.

Yahoo! News
Yahoo! News is a news website that originated as an internet-based news aggregator by Yahoo!. The site was created by a Yahoo! software engineer named Brad Clawsie in August 1996. Articles originally came from news services such as the Associated Press, Reuters, Fox News, Al Jazeera, ABC News, ''USA Today'', CNN and BBC News. In 2001, Yahoo! News launched the first "most-emailed" page on the web. It was well-received as an innovative idea, expanding people's understanding of the impact that online news sources have on news consumption. Yahoo allowed comments for news articles until December 19, 2006, when commentary was disabled. Comments were re-enabled on March 2, 2010. By 2011, Yahoo had expanded its focus to include original content, as part of its plans to become a major media organization.

Adhesion Railway
An adhesion railway relies on adhesion traction to move the train. Adhesion traction is the friction between the drive wheels and the steel rail. 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 cable attached to the cars or by railways that are moved by a pinion meshing with a 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 by requiring higher fuel consumption and by increasing the maintenance needed to address fatigue (material) damage, wear on rail heads and on the wheel rims and rail movement from traction and braking forces. Variation of friction coefficient Traction or friction is reduced when the top of the rail is wet or frosty or contaminated with grea ...

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 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 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, then ''Railwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

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. These were nicknamed "Bull Mooses". 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. Examples The 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 Union Pa ...

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 two ...

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates 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, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' ...

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 Council Bluffs, Iowa / Omaha, Nebraska, and San Francisco, California, over the grade of the first transcontinental railroad (aka the ''"Pacific Railroad"'') which had been opened on May 10, 1869. Passenger trains that operated over the line included the ''Overland Flyer'', later renamed the ''Overland Limited'', which also included a connection to Chicago. Although these passenger rail trains are no longer in operation, the Overland Route remains a common name for the line from Northern California to Chicago, now owned entirely by the Union Pacific. 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 City, Nevada, from 1861 to 1866, when Wells Fargo & Company took over the stagecoach's operation.

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 ...

Union Pacific Challenger
The Union Pacific Challengers are a type of simple articulated 4-6-6-4 steam locomotive built by American Locomotive Company (ALCO) from 1936 to 1944 and operated by the Union Pacific Railroad until the late 1950s. A total of 105 Challengers were built in five classes. They were nearly long and weighed 537 short tons (487 tonnes). They operated over most of the Union Pacific system, primarily in freight service, but a few were assigned to the ''Portland Rose'' and other passenger trains. Their design and operating experience shaped the design of the Big Boy locomotive type, which in turn shaped the design of the last three orders of Challengers. Two Union Pacific Challengers survive. The most notable is Union Pacific No. 3985, which was restored by the Union Pacific in 1981, then operated in excursion service as part of its heritage fleet program. Mechanical problems forced it out of service in October 2010; it was retired in January 2020 after the restoration of the 4-8-8-4 ...
