Trailing Axle
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pennsylvania Railroad
The Pennsylvania Railroad ( reporting mark PRR), legal name as the Pennsylvania Railroad Company, also known as the "Pennsy," was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. At its peak in 1882, the Pennsylvania Railroad was the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Over its existence, Pennsylvania Railroad acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Centra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AAR Wheel Arrangement
The AAR wheel arrangement system is a method of classifying locomotive A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for ... (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe Diesel locomotive, diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead (except geared steam locomotives, which are instead classified by their model and their number of trucks). The AAR system (like UIC) counts axles, unlike Whyte, which counts wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to t ...

UIC Classification
The UIC classification of locomotive axle arrangements, sometimes known as the German classification''The Railway Data File''. Leicester: Silverdale, 2000. p. 52. . or German system,Kalla-Bishop P.M. & Greggio, Luciano, ''Steam Locomotives'', Crescent, 1985, p. 226. describes the wheel arrangement of locomotives, multiple units and trams. It is used in much of the world, notable exceptions being the United Kingdom and North America. The classification system is managed by the International Union of Railways (UIC). Structure The UIC uses the following structure: ; Upper-case letters : Indicate driving axles, starting at A for a single axle. B thus indicates two and C indicates three consecutive pairs of driving wheels. ; Lower-case "o" : Related to driving axles (minimum 2, "B"), indicates they are individually driven by separate traction motors. ; Numbers : Consecutive non-driving axles, starting with 1 for a single axle. ; Prime symbol " ′ " : The axles indicated by a sing ...

DRG Class 61
The two German DRG Class 61 steam engines were express train locomotives specifically built by Henschel for the Henschel-Wegmann train in service with the Deutsche Reichsbahn. The Henschel-Wegmann train was an initiative of the German locomotive construction industry, intended to be able to demonstrate a powerful steam locomotive-hauled train alongside the emerging express diesel multiple units, such as the Hamburg Flyer. Construction Because it was planned to run the train in shuttle services to a tight time schedule, it was necessary that the engine could run at top speed in both directions. This resulted in a tank locomotive rather than the tender locomotive design otherwise used for long-distance high-speed links. In order to be able to attain the high running performance aimed at, locomotives and coaches were designed to be especially light, albeit the coal and water supplies still had to be sufficient for a one-way trip on the planned route. In building them, component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank Locomotive
A tank locomotive is a steam locomotive which carries its water in one or more on-board water tanks, instead of a more traditional tender (rail), tender. Most tank engines also have Fuel bunker, bunkers (or fuel tanks) to hold fuel; in a #Tender-tank, tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for Shunting (rail), shunting and shorter-distance Main line (railway), main line duties. Tank locomotives have #Advantages and disadvantages, advantages and disadvantages compared to traditional locomotives that required a separate tender to carry needed water and fuel.

Thuile Locomotive
The Thuile locomotive was a steam locomotive designed by M. Henri Thuile, of Alexandria, Egypt, and built in 1899. History Thuile proposed a 6-4-8 or 6-4-6 locomotive with 3-metre-diameter () driving wheels, but it was not built. The design was taken up by Schneider, of Le Creusot, who built a 4-4-6 with 2.5-metre-diameter () driving wheels, and a forward cab for the driver. The two-cylinder locomotive had Walschaerts valve gear and a double-lobed boiler of nickel-steel. The locomotive was exhibited at the International Exposition in Paris in 1900, and the trials were undertaken on the Chemin de Fer de l'Etat line between Chartres and Thouars Thouars () is a commune in the Deux-Sèvres department in western France. On 1 January 2019, the former communes Mauzé-Thouarsais, Missé and Sainte-Radegonde were merged into Thouars. It is on the River Thouet. Its inhabitants are known ....

4-4-6
A 4-4-6, in the Whyte notation for the classification of steam locomotives by wheel arrangement, is a locomotive with: * four (4) leading wheels (at the front of the locomotive) * four (4) driving wheels (2 axles) fixed in a rigid frame, and * six (6) trailing wheels (normally mounted in a trailing truck). Usage United States The Providence, Warren and Bristol railroad's No. 4 ''Annawamscutt'' was the only example of a 4-4-6 in the United States. It was rebuilt into a 0-4-4T in 1891. France The only example of this wheel arrangement in France was the Thuile locomotive. Other equivalent classifications are: * UIC classification: 2B3 (also known as German classification * Italian classification), and * French classification Under the French classification system for locomotive wheel arrangements, the system is slightly different for steam and electric/diesel vehicles. Steam The French system counts axles, rather than wheels. As with Whyte notation, a conventional r ...: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mason Bogie
Mason Bogie locomotives (also known as Mason Fairlie locomotives) are a type of articulated tank locomotive suited for sharp curves and uneven track, once commonly used on narrow-gauge railways in the United States. 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. ''Janus'' was not commercially successful and was not repeated, so Mason experimented with a different design. 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 a set of standard plans based on this design with modified steam del ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
6-4-4-6
A 6-4-4-6 steam locomotive, in the Whyte notation for describing locomotive wheel arrangements, is one with six leading wheels, two sets of four driving wheels, and six trailing wheels. Other equivalent classifications are: * UIC classification: 3BB3 (also known as German classification and Italian classification) * French classification: 3223 * Turkish classification: 2525 * Swiss classification: 2/5+2/5 up to the early 1920s, later 4/10 Only one was produced, the Pennsylvania Railroad's sole class S1 of 1939. It was a duplex locomotive, the longest and heaviest rigid frame reciprocating steam locomotive ever built and is referred to as the ''Pennsylvania Type''.
