Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and six trailing wheels on three axles. Overview The wheel arrangement was usually found on Single Fairlie or Mason Bogie locomotives. The Fairlie locomotive was invented and patented in 1864 by the Scottish engineer Robert Francis Fairlie. The first Fairlie locomotives later became known as Double Fairlies. A variation of the original Fairlie concept was the Single Fairlie, also known as the Mason Fairlie. The Single Fairlie design was essentially half a Double Fairlie. It retained the ability to negotiate sharp curves and, while it abandoned the bidirectional nature of the Double Fairlie, it regained the ability of conventional locomotives to have a large water and coal bunker behind the cab and to use a trailing tender if necessary. Most Single Fairlies were tank locomotives and early models were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Fairlie Locomotive
A Fairlie is a type of articulated locomotive, articulated steam locomotive that has the driving wheels on bogies. The locomotive may be double-ended (a double Fairlie) or single ended (a single Fairlie). Fairlies are most famously associated with the Ffestiniog Railway in North Wales. While the Fairlie locomotives are now used only on heritage railways, the vast majority of diesel locomotive, diesel and electric locomotives in the world today follow a form not very different from the Fairlie — two power trucks with all axles driven, and many also follow the Fairlie's double-ended concept, capable of being driven equally well in both directions. Development of the design The Scottish people, Scottish engineer Robert Francis Fairlie patented his design in 1864. He had become convinced that the conventional pattern of locomotive was seriously deficient; they wasted weight on unpowered wheels (the maximum tractive effort a locomotive can exert is a function of the weight ...

Mason Bogie
Mason Bogie locomotives (also known as Mason Fairlie locomotives) are a type of articulated steam locomotive suited for sharp curves and uneven track, once commonly used on narrow gauge railways in the United States of America. The design is a development of the Single Fairlie locomotive. Concept and Development The American licensee of the Fairlie Patent steam locomotive was the firm of William Mason, located in Taunton, Massachusetts. Mason's first Fairlie locomotive was the ''Janus'', an Double Fairlie built in 1871. It became obvious that, for all the Double Fairlie locomotive's advantages, its disadvantages outweighed them. In 1869, a Single Fairlie locomotive had been designed and constructed by Alexander McDonnell for the Great Southern and Western Railway in Ireland. This had a single boiler with one articulated, powered truck beneath it and a second, unpowered truck beneath the cab and bunker. Mason developed this design, which he called the Mason Bogie (''bogie'' i ... [...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 classificat ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

New York, New Haven And Hartford Railroad
The New York, New Haven and Hartford Railroad , commonly known as The Consolidated, or simply as the New Haven, was a railroad that operated in the New England region of the United States from 1872 to December 31, 1968. Founded by the merger of the New York and New Haven Railroad, New York and New Haven and Hartford and New Haven Railroad, Hartford and New Haven railroads, the company had near-total dominance of railroad traffic in Southern New England for the first half of the 20th century. Beginning in the 1890s and accelerating in 1903, New York banker J. P. Morgan sought to monopolize New England transportation by arranging the NH's acquisition of 50 companies, including other railroads and steamship lines, and building a network of electrified trolley lines that provided interurban transportation for all of southern New England. By 1912, the New Haven operated more than of track, with 120,000 employees, and practically monopolized traffic in a wide swath from Boston to New ...

Old Colony Railroad
The Old Colony Railroad (OC) was a major railroad system, mainly covering southeastern Massachusetts and parts of Rhode Island, which operated from 1845 to 1893. Old Colony trains ran from Boston to points such as Plymouth, Fall River, New Bedford, Newport, Providence, Fitchburg, Lowell and Cape Cod. For many years the Old Colony Railroad Company also operated steamboat and ferry lines, including those of the Fall River Line with express train service from Boston to its wharf in Fall River where passengers boarded luxury liners to New York City. The company also briefly operated a railroad line on Martha's Vineyard, as well as the freight-only Union Freight Railroad in Boston. The OC was named after the "Old Colony", the nickname for the Plymouth Colony. From 1845 to 1893, the OC network grew extensively largely through a series of mergers and acquisitions with other established railroads, until it was itself acquired by the New York, New Haven and Hartford Railroa ...

Boston, Clinton, Fitchburg And New Bedford Railroad
The Boston, Clinton, Fitchburg and New Bedford Railroad was a railroad in Massachusetts. It was formed on June 1, 1876, when the Boston, Clinton and Fitchburg Railroad merged with the New Bedford Railroad. The Boston, Clinton and Fitchburg Railroad connected with the key railroad hubs of Worcester, Framingham, and Ayer, as well as several important industrial towns such as Fitchburg and Lowell, with the latter coming through a lease of the Framingham and Lowell Railroad. The New Bedford Railroad linked Framingham with New Bedford, which was a key deep-water port. In 1879, the Boston, Clinton, Fitchburg and New Bedford Railroad was leased to the Old Colony Railroad, but on October 1 of that same year it still extended its lease of the Framingham and Lowell Railroad to 998 years. On September 10, 1881, the Framingham and Lowell Railroad was deeded on execution sale to the Boston, Clinton, Fitchburg, and New Bedford Railroad and renamed to the Lowell and Framingham Railroad Compa ...

Robert Francis Fairlie
Robert Francis Fairlie (either March 1831 or 5 April 1830, in Glasgow – 31 July 1885, in London) was a Scottish-born railway engineer. Early life Fairlie was born in Glasgow, the son of T. Archibald Fairlie (an engineer) and Margaret Fairlie. He trained at Crewe and Swindon railway works, then joined first the Londonderry and Coleraine Railway as Locomotive Superintendent in 1852, and four years later the Bombay, Baroda & Central India Railway before returning to London in 1859 to establish himself as a railway engineering consultant. Ffestiniog Railway He is chiefly known for the invention of the Fairlie double-bogie articulated locomotive (patented in 1864) that is particularly associated with tightly curved railways and especially narrow gauge mountain lines. The first such, the ''Pioneer'', was built in 1865 for the Neath and Brecon Railway, but it was with the '' Little Wonder'' built in 1869 for the Festiniog Railway that Fairlie made his name as the inventor of ...

Driving Wheel
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunting locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets which are linked together within the set. Diameter Driving wheels ...

Trailing Wheel
On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle ( wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients. Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century. As demand for more powerful locomotives increased, trailing wheels began to be used to support the crew cab and rear firebox area. Trailing wheels first appeared on American locomotives between 1890 and 1895, but their axle worked in rigid pedestals. It enabled boilers to be lowered, since the top of the main frames was dropped down behind the driving wheels and under the firebox. The firebox could also be longer and wider, increasing the heating surface area and steam generation c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
