4-8-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels, eight powered and coupled driving wheels and two trailing wheels. This type of steam locomotive is commonly known as the Mountain type. Overview The Colony of Natal in South Africa and New Zealand were innovators of the Mountain wheel arrangement. The Natal Government Railways (NGR) placed in service the first tank engines with the 4-8-2 arrangement, and the NGR was also first to modify tender locomotives to use a 4-8-2 wheel arrangement. The New Zealand Railways Department (NZR) introduced the first tender locomotives designed and built as 4-8-2. In 1888, the Natal Government Railways placed the first five of its eventual one hundred Class D tank locomotives in service. The locomotive was designed by William Milne, the locomotive superintendent of the NGR from 1877 to 1896, and was built by Dübs & Company. This was the first known use of the whe ...

South African Class 3 4-8-2
The South African Railways Class 3 of 1909 was a steam locomotive from the pre-Union era in the Colony of Natal. In 1909, the Natal Government Railways placed the world’s first true Mountain type locomotive in service when five Class B tender locomotives were commissioned. Another 25 were placed in service in 1911. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class 3. The Mountain wheel arrangement went on to become the most numerous steam locomotive wheel configuration in use in South Africa.Classification of S.A.R.

South African Class A 4-8-2T
The South African Railways Class A 4-8-2T of 1888 was a steam locomotive from the pre-Union era in the Colony of Natal. In 1888, the Natal Government Railways placed the first five of its eventual one hundred Class D steam locomotives in service. The last was delivered in 1899. They were the first locomotives in the world to be built with a wheel arrangement, later to become known as the Mountain type. In 1912, when these locomotives were assimilated into the South African Railways, they were renumbered and designated Class A. In 1915, another two Class A locomotives were built from spare parts.South African Railways and Harbours Locomotive Diagram Book, 2'0" & 3'6" Gauge Steam Locomotives, 15 August 1941, as amended Manufacturers The Natal Government Railways (NGR) Class D tank locomotive was designed by William Milne, the Locomotive Superintendent of the NGR from 1877 to 1896, and was built by Dübs and Company.

4-8-4
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern. Overview Development The wheel arrangement was a progression from the Mountain type and, like the Berkshire and Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which allowed greater production of steam. The four-wheel leading truck gave stability at speed and the eight driving wheels gave greater adhesion. The evolution to the type occurred in the United States of America soon after the Lima Lo ...

South African Class 1B 4-8-2
The South African Railways Class 1B 4-8-2 of 1904 was a steam locomotive from the pre-Union era in the Colony of Natal. In 1904, the Natal Government Railways placed fifty Class B locomotives with a Mastodon wheel arrangement in service. Of these, six were modified in 1906 to Altered Class B locomotives, the first tender engines in the world with a Mountain wheel arrangement. In 1912, when these six engines were assimilated into the South African Railways, they were renumbered and designated Class 1B.Espitalier, T.J.; Day, W.A.J. (1944).

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] |
South African Class 1 4-8-0
The South African Railways Class 1 4-8-0 of 1904 was a steam locomotive from the pre-Union era in the Colony of Natal. In 1904, the Natal Government Railways placed fifty Class B Mastodon type steam locomotives in service. Six of them were modified to a 4-8-2 Mountain type wheel arrangement in 1906. In 1912, when the remaining 44 locomotives were assimilated into the South African Railways, they were renumbered and designated .Espitalier, T.J.; Day, W.A.J. (1944). ''The Locomotive in South Africa - A Brief History of Railway Development. Chapter III - Natal Government Railways'' (Continued). South African Railways and Harbours Magazine, July 1944. pp. 504-505. Design Because of the limited coal and water range of the existing fleet of Natal Government Railways (NGR) tank locomotives as well as the necessity to double- and even triple-head over the worst sections of the mainline, NGR Locomotive Superintendent D.A.

North British Locomotive Company
The North British Locomotive Company (NBL, NB Loco or North British) was created in 1903 through the merger of three Glasgow locomotive manufacturing companies; Sharp, Stewart and Company (Atlas Works), Neilson, Reid and Company (Hyde Park Works) and Dübs and Company (Queens Park Works), creating the largest locomotive manufacturing company in Europe and the British Empire. Its main factories were located at the neighbouring Atlas and Hyde Park Works in central Springburn, as well as the Queens Park Works in Polmadie. A new central Administration and Drawing Office for the combined company was completed across the road from the Hyde Park Works on Flemington Street by James Miller in 1909, later sold to Glasgow Corporation in 1961 to become the main campus of North Glasgow College (now Glasgow Kelvin College). The two other Railway works in Springburn were St. Rollox railway works, owned by the Caledonian Railway and Cowlairs railway works, owned by the North British Railway ...

NZR X Class
The New Zealand X class was a pioneering class of eighteen 4-8-2 steam locomotives built for New Zealand Railways Department (NZR) and designed by A. L. Beattie that operated on the national rail network of New Zealand. In 1908, a heavy and powerful locomotive was required to haul traffic on the newly completed mountainous central section of the North Island Main Trunk Railway, and as a logical progression of the 4-6-2 Q class design, the 4-8-2 wheel arrangement was created for the X class. Overview When the first X was completed in 1908 at NZR's Addington Workshops in Christchurch, it was the very first 4-8-2 tender locomotive built in the world. The 4-8-2 design went on to be popular in the United States and was nicknamed the "Mountain" type; one theory suggests this name stems from the mountainous terrain that inspired the X's design, while another suggests the Chesapeake and Ohio Railway first coined the name in reference to its 4-8-2s of 1911 that were built to oper ...

4-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Twelve-wheeler. Overview The first locomotive is believed to have been the ''Centipede'', a tender locomotive built by Ross Winans in 1855 for the Baltimore and Ohio Railroad in the United States of America, where it remained in service for nearly twenty years. It appears to have been delivered in a cab-forward type of configuration that was modified to a Camel configuration in 1864.Carling, D. Rock (1972). ''4-8-0 Tender Locomotives''. Drake Publishers Inc. On a Camel locomotive the cab was mounted atop the boiler, unlike the later Camelback locomotive whose cab straddled the boiler and that first appeared around 1877.

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] |
Alfred Beattie
Alfred Luther Beattie (1852 – 2 May 1920), typically referred to as A. L. Beattie, was a pioneering locomotive engineer. Born in Yorkshire, England,The Rock, September 2010 http://www.stpeterscaversham.org.nz/The%20Rock/1009.pdf he gained fame as the Chief Mechanical Engineer of the New Zealand Railways Department (NZR) between 1900 and 1913. During this time, Beattie designed the Q class, the first 4-6-2 steam locomotive class in the world, and he was also one of the earliest people to use other wheel arrangements. Early life Born in 1852, his birth was registered in Hunslet as Alfred Luther Betty. He arrived in New Zealand at Port Chalmers in 1876, when he joined NZR. In February 1897, Beattie was given the position of Locomotive Engineer at Addington Workshops in Christchurch.McGavin, ''Steam Locomotives of New Zealand'', pg. 53. Unlike in some countries, where "locomotive engineer" is the title of regular train drivers, the title in New Zealand then referred to a specif ...
