Union Pacific Big Boy 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. It now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fairplex
Fairplex has been the home of the L.A. County Fair since 1922. Known prior to 1984 as the Los Angeles County Fairgrounds, it is located in the city of Pomona, California. The L.A. County Fair is held during the month of May since 2022, but the facility is used year-round to host a variety of educational, commercial, and entertainment such as trade and consumer shows, conventions, and sporting events. Fairplex is owned by Los Angeles County, but is leased to and is governed by an independent, self-supporting non-profit organization, the Los Angeles County Fair Association, which manages and produces the county fair and re-invests surplus revenues generated by the fair and other events in the maintenance and development of the facility. Facilities Having begun in 1922 with donated by the City of Pomona, the Fairplex grounds now cover and include nearly of indoor exhibit space. Slightly less than half of the grounds are given over to paved parking areas to accommodate 30,000 v ... [...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 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.

Compound Locomotive
A compound locomotive is a steam locomotive which is powered by a compound engine, a type of steam engine where steam is expanded in two or more stages. The locomotive was only one application of compounding. Two and three stages were used in ships, for example. Compounding became popular for railway locomotives from the early 1880s and by the 1890s were becoming common. Large numbers were constructed, mostly two- and four-cylinder compounds, in France, Germany, Austria, Hungary, and the United States. It declined in popularity due to maintenance issues and because superheating provided similar efficiencies at lower cost. Nonetheless, compound Mallets were built by the Norfolk and Western Railway right up to 1952. Introduction In the usual arrangement for a compound engine the steam is first expanded in one or two high-pressure ''(HP)'' cylinders, then having given up some heat and lost some pressure, it exhausts into a larger-volume low-pressure ''(LP)'' cylinder, (or two, - or ...

Mallet Locomotive
The Mallet locomotive is a type of articulated steam railway locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919). The front of the locomotive articulated on a bogie. The compound steam system fed steam at boiler pressure to high-pressure cylinders driving the rear set of driving wheels (rigidly connected to the boiler). The exhaust steam from these cylinders was fed into a low-pressure receiver and was then sent to low-pressure cylinders that powered the driving wheels on the swiveling bogie towards the front of locomotive. Compounding Steam under pressure is converted into mechanical energy more efficiently if it is used in a compound engine; in such an engine steam from a boiler is used in high-pressure (HP) cylinders and then under reduced pressure in a second set of cylinders. The lower-pressure steam occupies a larger volume and the low-pressure (LP) cylinders are larger than the high-pressure cylinders. A third stage (triple expansion) may be empl ...

Firebox (steam Engine)
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler. Steam locomotive fire tube firebox In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel) or a firing pan (liquid fuel). If the engine burns solid fuel, like wood or coal, there is a grate covering most of the bottom of the firebox to hold the fire. An ashpan, mounted underneath the firebox and below the grates, catches and collects hot embers, ashes, and other solid combustion waste as it falls through the grates. In a coal-burning locomotive, the grates may be shaken to clean dead ash from the bottom of the fire. They are shaken either manually or (in larger locomotiv ...

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 ...

4-6-6-4
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 proble ...

Ruling Gradient
The term ruling grade is usually used as a synonym for "steepest climb" between two points on a railroad. More simply, the steepest grade to be climbed dictates how powerful the motive power (or how light the train) must be in order for the run to be made without assistance. Even if 99% of the line could be run with a low-powered (and inexpensive) locomotive, if at some point on the line there is a steeper gradient than such train would be able to climb, this gradient "rules" that a more powerful locomotive must be used, in spite of it being far too powerful for the rest of the line. This is why special "helper engines" (also dubbed "Bankers") are often stationed near steep grades on otherwise mild tracks. It is cheaper than running a too-powerful locomotive over the entire track mileage just in order to make the grade, especially when multiple trains run over the line each day (to help justify the fixed daily cost of the helper operation). In the 1953 edition of ''Railway Engineer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positive Train Control
Positive train control (PTC) is a family of automatic train protection systems deployed in the United States. Most of the United States' national rail network mileage has a form of PTC. These systems are generally designed to check that trains are moving safely and to stop them when they are not. A simplistic form of train traffic governance is ''negative'' train control, where trains must stop when issued a stop order and can move in the absence of such. An example of negative train control is Indusi. In contrast, ''positive'' train control restricts the train movement to an explicit allowance; movement is halted upon invalidation. A train operating under PTC receives a ''movement authority'' containing information about its location and where it is allowed to safely travel. As of 2019, the U.S. freight rail industry trade organization AAR claimed that the nation's largest freight railroads were operating PTC across 83.2 percent of the required route miles.

Excursion Train
An excursion train is a chartered train run for a special event or purpose. Examples are trains to major sporting event, trains run for railfans or tourists, and special trains operated by the railway company for employees and prominent customers. United Kingdom A number of excursion trains are run in the United Kingdom and in some cases there are regular steam worked passenger services over some routes, one such train being ''The Jacobite (steam train), The Jacobite'' which runs Monday to Friday from Fort William railway station, Fort William to Mallaig railway station, Mallaig from April to October. A second afternoon train also runs from May to mid September but on weekdays only, weekend services running from June to October. A number of Christmas Jacobite's have even started running on select days in December. There are also a number of routes across the UK which are famed for running excursion trains, examples include: Settle & Carlisle line, Cumbrian Coast line, North War ...
