4-6-0T
A 4-6-0 steam locomotive, under the Whyte notation for the classification of steam locomotives by wheel arrangement, has four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels. In the mid-19th century, this wheel arrangement became the second-most-popular configuration for new steam locomotives in the United States, where this type is commonly referred to as a ten-wheeler.White, John H., Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York, NY: Dover Publications. p. 57. As locomotives pulling trains of lightweight all-wood passenger cars from the 1890 to the 1920s, they were exceptionally stable at near speeds on the New York Central's New York-to-Chicago Water Level Route and on the Reading Railroad's line from Camden to Atlantic City, New Jersey.

South African Class C 4-6-0T
The South African Railways Class C 4-6-0T of 1879 was a steam locomotive from the pre-Union era in the Colony of Natal. Between 1879 and 1885, the Natal Government Railways placed thirty-seven Ten-wheeler type tank steam locomotives in service. Of these, the first seven were built as Mogul type locomotives and were subsequently modified to a wheel arrangement. By 1908 they were designated Class G and in 1912, when some of the survivors were assimilated into the South African Railways, they were renumbered and reclassified to Class C. These were the oldest pre-Union locomotives to be classified and renumbered onto the SAR roster.Classification of S.A.R. Engines with Renumbering Lists, issued by the Chief Mechanical Engineer's Office, Pretoria, January 1912, pp. 7, 13, 19 (Reprinted in April 1987 by SATS Museum, R.3125-6/9/11-1000) Origins In 1875, when the Natal Government took over all the assets of the Natal Railway Company and formed the Natal Government Railways (NGR), tw ...

4-6-4
Under the Whyte notation for the classification of locomotives, represents the wheel arrangement of four leading wheels, six powered and coupled driving wheels and four trailing wheels. In France where the type was first used, it is known as the Baltic while it became known as the Hudson in most of North America. Overview Tender locomotives The 4-6-4 tender locomotive was first introduced in 1911 and throughout the 1920s to 1940s, the wheel arrangement was widely used in North America and to a lesser extent in the rest of the world. The type combined the basic design principles of the 4-6-2 type with an improved boiler and larger firebox that necessitated additional support at the rear of the locomotive. In general, the available tractive effort differed little from that of the 4-6-2, but the steam-raising ability was increased, giving more power at speed. The 4-6-4 was best suited to high-speed running across flat terrain. Since the type had fewer driving wheels than carryin ...

2-6-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels. This arrangement is commonly called a Mogul. Overview In the United States and Europe, the wheel arrangement was principally used on tender locomotives. This type of locomotive was widely built in the United States from the early 1860s to the 1920s. Although examples were built as early as 1852–53 by two Philadelphia manufacturers, Baldwin Locomotive Works and Norris Locomotive Works, these first examples had their leading axles mounted directly and rigidly on the frame of the locomotive rather than on a separate truck or bogie. On these early 2-6-0 locomotives, the leading axle was merely used to distribute the weight of the locomotive over a larger number of wheels. It was therefore essentially an 0-8-0 with an unpowered leadin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-6-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The locomotive became almost globally known as a Pacific type. Overview The introduction of the design in 1901 has been described as "a veritable milestone in locomotive progress". On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric locomotive, electric or diesel locomotive, diesel-electric locomotives during the 1950s and 1960s. Nevertheless, new Pacific designs continued to be built until the mid-1950s. The type is generally considered to be an enlargement of the 4-4-2 (locomotive), Atlantic type, although its NZR Q class (1901), prototype had ...

Natal Government Railways
The Natal Government Railways (NGR) was formed in January 1877 in the Colony of Natal. In 1877, the Natal Government Railways acquired the Natal Railway Company for the sum of £40,000, gaining the line from the Point to Durban and from Durban to Umgeni. This move, inspired in part by the neighbouring Cape Prime Minister John Molteno's 1873 establishment of the Cape Government Railways, was intended to drive the extension of Natal's railways inland, towards the Drakensberg and eventually the Orange Free State. The Natal Government Railways also adopted the Cape gauge. The core line went from Durban to Volksrust, but reached Charlestown ( from the border of the South African Republic) in 1891 and was linked to the Witwatersrand in 1895. Other important lines were the one linking with the Orange Free State reaching Harrismith in 1892, as well as the North Coast and South Coast lines. In 1910, the Union of South Africa was formed and in 1912 the NGR combined with the other colonies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prussian P 8
The Prussian Class P 8 of the Prussian state railways (DRG Class 38.10-40 of the Deutsche Reichsbahn) was a 4-6-0 steam locomotive built from 1906 to 1923 by the Berliner Maschinenbau (previously Schwartzkopff) and twelve other German factories. The design was created by Robert Garbe. It was intended as a successor to the Prussian P 6, which was regarded as unsatisfactory. Construction Because Garbe was an advocate of the simplest possible designs, a straightforward, superheated steam, two-cylinder driving gear was envisaged. The P 8 benefited especially from superheated steam technology, which had just been developed by Wilhelm Schmidt (nicknamed 'Hot Steam Schmidt'), that led to outstanding performance for those times. The P 8 was a very economical locomotive that did not make great demands on the ability of the engine driver. At the outset Garbe even designed the P 8 as an express train locomotive, with the expectation of attaining a top speed of . As a result ...

Leading Truck
The leading wheel or leading axle or pilot wheel of a steam locomotive is an unpowered wheel or axle located in front of the driving wheels. The axle or axles of the leading wheels are normally located on a leading truck. Leading wheels are used to help the locomotive negotiate curves and to support the front portion of the boiler. Overview Importantly, the leading bogie does not have simple rotational motion about a vertical pivot, as might first be thought. It must also be free to slip sideways to a small extent, otherwise the locomotive is unable to follow curves accurately, and some kind of springing mechanism is normally included to control that movement and provide a tendency to return to centre. A sliding bogie of that type was patented by William Adams in 1865. The first use of leading wheels is commonly attributed to John B. Jervis, who employed them in his 1832 design for a locomotive with four leading wheels and two driving wheels (a type that became known as the '' ...

Adhesive Weight
Adhesive weight is the weight on the driving wheels of a locomotive, which determines the frictional grip between wheels and rail, and hence the drawbar pull which a locomotive can exert. See also *Factor of adhesion *Tractive effort As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion. In railway engineering, the term tr ... References Locomotives {{rail-transport-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-8-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike. At times it was also referred to on some railroads in the United States of America as the McAdoo Mikado and, during World War II, the MacArthur. The notation 2-8-2T indicates a tank locomotive of this wheel arrangement, the "T" suffix indicating a locomotive on which the water is carried in tanks mounted on the engine rather than in an attached tender. Overview The 2-8-2 wheel arrangement allowed the locomotive's firebox to be placed behind instead of above the driving wheels, thereby allowing a larger firebox that could be both wide and deep. This supported a greater rate of combustion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Gölsdorf
Karl Gölsdorf (8 June 1861 – 18 March 1916) was an Austrian engineer and locomotive designer. Early life Karl Gölsdorf was born on 8 June 1861 in Vienna, the son of Louis Adolf Gölsdorf. Even as a schoolboy he was introduced to locomotive design by his father, the chief mechanical engineer (''Maschinendirektor'') of the Imperial and Royal Southern Railway (''k.u.k. Südbahn''). From 1880 to 1884 he attended the Vienna Technical High School and completed his diploma with distinction. In 1885 he joined the ''Wiener Maschinenfabrik'' (Vienna engineering works) as a design engineer. In 1889 he became head of assembly for locomotive construction. On 1 November 1891 he joined the design office of the Austrian State Railway as an engineer-''Adjunkt'' and began his creative work there. Inventions In 1893 he invented an effective starting system for compound locomotives. Until then the locomotive starting systems in common use in Austria, with its sometimes taxing railway lines, di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Gauge
A cape is a clothing accessory or a sleeveless outer garment which drapes the wearer's back, arms, and chest, and connects at the neck. History Capes were common in medieval Europe, especially when combined with a hood in the chaperon. They have had periodic returns to fashion - for example, in nineteenth-century Europe. Roman Catholic clergy wear a type of cape known as a ferraiolo, which is worn for formal events outside a ritualistic context. The cope is a liturgical vestment in the form of a cape. Capes are often highly decorated with elaborate embroidery. Capes remain in regular use as rainwear in various military units and police forces, in France for example. A gas cape was a voluminous military garment designed to give rain protection to someone wearing the bulky gas masks used in twentieth-century wars. Rich noblemen and elite warriors of the Aztec Empire would wear a tilmàtli; a Mesoamerican cloak/cape used as a symbol of their upper status. Cloth and clothing w ...

2-6-4
Under the Whyte notation for the classification of steam locomotives, a locomotive has two leading wheels, six coupled driving wheels and four trailing wheels. This arrangement is commonly called Adriatic. Overview With only a few known exceptions, the Adriatic wheel arrangement was usually used on tank locomotives, for which various suffixes to indicate the type of tank would be added to the wheel arrangement, for example for an engine with side-tanks. Tender locomotives The earliest known example was the South African Class 6Z, designed by Cape Government Railways (CGR) Chief Locomotive Superintendent Hazlitt Beatty in 1901. The first engines of the class were modified 2-6-2 Prairie locomotives which were equipped with two-axle trailing bogies. In 1902, more were placed in service, but built with the wheel arrangement. The latter were the first known tender locomotives in the world to be built with this wheel arrangement.Neilson, Reid works list, compiled by Austrian loc ...
