2-6-6-4
In the Whyte notation for the classification of steam locomotive wheel arrangement, a 2-6-6-4 is a locomotive with a two-wheel leading truck, two sets of six driving wheels, and a four-wheel trailing truck. All 2-6-6-4s are articulated locomotives, of the Mallet or related simple articulated type. Other equivalent classifications are: *UIC classification: (1'C)C2 (also known as German classification and Italian classification) *French classification: 130+032 *Turkish classification: 34+35 *Swiss classification: 3/4+3/5 The UIC classification is refined to (1'C)C2 for Mallet locomotives. The 2-6-6-4 was a fairly late development, a product of the superpower steam concept, introduced by the Lima Locomotive Works, which encouraged the use of large fireboxes supported by four-wheel trailing trucks. Such a firebox could sustain a rate of steam generation to meet any demands of the locomotive's cylinders, even at high speed. High speeds were certainly among the design goals for the ...

Norfolk And Western Railway Class A
The Norfolk and Western A was a class of 43 2-6-6-4 steam locomotives built by the railroad's own Roanoke Shops between 1936 and 1950 and operated until the late 1950s. The locomotives hauled fast and heavy freight trains for the railroad and only one has been preserved, Norfolk and Western 1218, No. 1218. History Upon delivery on the class starting in 1936, starting with 1200 and 1201, they were tested and proved successful. The railroad was satisfied with the class and bought eight more the following year. During testing, N&W officials were very impressed with their performance, as they were capable of pulling 4,800 tons at 25 mph on a 0.5% grade and 7,500 tons at 64 mph on level track. During World War II, the railroad built 25 more "A"s between 1943 and 1944 and finally eight more between 1949 and 1950. They were some of the last mainline steam locomotives to be put into service. The locomotives had a cast-steel frame and Timken Roller Bearing Company, Timken roller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk And Western 1218
Norfolk and Western 1218 is a preserved four-cylinder simple articulated 2-6-6-4 steam locomotive, built in June 1943 by the Norfolk and Western's (N&W) East End Shops in Roanoke, Virginia as part of the N&W's class "A" fleet of fast freight locomotives. It was retired from regular revenue service in July 1959, and was later restored by Norfolk Southern for excursion service on their steam program, pulling excursions throughout the eastern United States from 1987 to 1991. It is currently on static display at the Virginia Museum of Transportation in Roanoke, Virginia. Historic significance No. 1218 is the sole survivor of the Norfolk and Western's class A locomotives and the only surviving 2-6-6-4 steam locomotive in the world. While smaller than Union Pacific's famous and more numerous " Challenger" class of 4-6-6-4 locomotives, Norfolk and Western's design racked up unmatched records of performance in service. During No. 1218's excursion career, it was the most powerful oper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk And Western Railway
The Norfolk and Western Railway , commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America". In 1986, N&W merged with Southern Railway to form today’s Norfolk Southern Railway. The N&W was famous for manufacturing its own steam locomotives, which were built at the Roanoke Shops, as well as its own hopper cars. After 1960, N&W was the last major Class I railroad using steam locomotives; the last remaining Y class 2-8-8-2s would eventually be retired between 1964 and 1965. In December 1959, the N&W merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the Nickel Plate Road and Wabash formed a system that operated of road on of track from North C ...

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 leadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superpower Steam
"Superpower steam" was a term coined by Lima Locomotive Works in the mid-1920s, referring to steam locomotives with booster-equipped four-wheel trailing trucks supporting large fireboxes, as well as enlarged superheaters. The wheel arrangements introduced in the 1920s for these locomotives were the 4-6-4's, 2-8-4's, 4-8-4's and 2-10-4's; and in the 1930s, the 2-6-6-4's. The term "superpower" was later often applied to all locomotives with 4-wheel trailing truck arrangements, though many did not have boosters and almost all steam of any wheel arrangement built after that time had large superheaters. The design was invented by Lima for the New York Central's Boston and Albany Railroad. The design was invented by Lima's Vice President of Engineering, William Woodard, who had experimented with a New York Central 2-8-2 Mikado in 1922. The new design called for double the firebox size than the earlier Mikados, thus giving it more grate area leading to the development of the 2-8-4. The l ...

Virginia Museum Of Transportation
The Virginia Museum of Transportation is a museum devoted to the topic of transportation located in Downtown Roanoke, Virginia, US. children under two years do not to buy tickets and students can get a discounted $10.5 ticket. History The Virginia Museum of Transportation began its life in 1963 as the Roanoke Transportation Museum located in Wasena Park in Roanoke, Virginia. The museum at that time was housed in an old Norfolk & Western Railway freight depot on the banks of the Roanoke River. The earliest components of the museum's collection included a United States Army Jupiter rocket and the J class steam locomotive No. 611, donated by Norfolk & Western Railway to the City of Roanoke where many of its engines were constructed. The museum expanded its collection to include other pieces of rail equipment such as a former DC Transit PCC streetcar, and a number of horse-drawn vehicles including a hearse, a covered wagon, and a Studebaker wagon.

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 classificat ...

Seaboard Air Line
The Seaboard Air Line Railroad , which styled itself "The Route of Courteous Service," was an American railroad which existed from April 14, 1900, until July 1, 1967, when it merged with the Atlantic Coast Line Railroad, its longtime rival, to form the Seaboard Coast Line Railroad. Predecessor railroads dated from the 1830s and reorganized extensively to rebuild after the American Civil War. The company was headquartered in Norfolk, Virginia, until 1958, when its main offices were relocated to Richmond, Virginia. The Seaboard Air Line Railway Building in Norfolk's historic Freemason District still stands and has been converted into apartments. At the end of 1925 SAL operated 3,929 miles of road, not including its flock of subsidiaries; at the end of 1960 it reported 4,135 miles. The main line ran from Richmond via Raleigh, North Carolina, Columbia, South Carolina, and Savannah, Georgia to Jacksonville, Florida, a major interchange point for passenger trains bringing travelers ...

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 l ...

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Maryland, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dieselisation
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 sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
