0-8-4T
Under the Whyte notation for the classification of steam locomotives, 0-8-4 represents the wheel arrangement of no leading wheels, eight powered and coupled driving wheels on four axles, and four trailing wheels on two axles (usually in a trailing bogie). Equivalent classifications Other equivalent classifications are: *UIC classification: D2 (also known as German classification and Italian classification) *French classification: 042 *Turkish classification: 46 *Swiss classification: 4/6 Examples All examples of this wheel arrangement were tank locomotives; there are no 0-8-4 tender locomotives recorded. United Kingdom The tank locomotives were themselves rare. Two separate classes were built in the UK, by two different railway companies. Both of these had their origins with an 0-8-0 tender design. Both classes were designed as powerful, but slow-speed, locomotives for heavy shunting. They did not require high speed or long range, so had no need for a leading truck or the ...

GCR Class 8H
The Great Central Railway Class 8H (LNER Class S1) was a class of 0-8-4T steam tank locomotives designed by John G. Robinson for hump shunting at Wath marshalling yard. Overview Four locomotives were built in 1907/1908 for the Great Central Railway. They were fitted with three cylinders. This gave a more even torque than with a 2-cylinder locomotive and reduced the risk of wheelslip under heavy load. All four passed into London and North Eastern Railway ownership at the 1923 grouping. At the time all four locomotives were allocated to Mexborough engine shed. These were powerful locomotives but even more power was required so, in 1930, one locomotive was fitted with a superheater and a booster engine and classified S1/2. Two new locomotives (with superheaters and boosters) were built by the LNER in 1932 and classified S1/3. The remaining (non-booster) locomotives were classified S1/1 and were also fitted with superheaters. All the boosters were removed in 1943. All six ...

Great Central Railway
The Great Central Railway in England was formed when the Manchester, Sheffield and Lincolnshire Railway changed its name in 1897, anticipating the opening in 1899 of its London Extension. On 1 January 1923, the company was grouped into the London and North Eastern Railway. History New name On assuming its new title, the Great Central Railway had a main line from Manchester London Road Station via , Sheffield Victoria, and Grimsby to . A second line left the line at Penistone and served , and Scunthorpe, before rejoining the Grimsby line at . Other lines linked Sheffield to Barnsley (via ) and Doncaster (via Rotherham) and also and Wrawby Junction. Branch lines in north Lincolnshire ran to Barton-upon-Humber and New Holland and served ironstone quarries in the Scunthorpe area. In the Manchester area, lines ran to Stalybridge and Glossop. In the 1890s, the MS&LR began constructing its Derbyshire lines, the first part of its push southwards. Leaving its east–west mai ...

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] |
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 ...

NER Class X
The NER Class X (LNER Class T1) was a class of 4-8-0T tank locomotive designed by Wilson Worsdell for the North Eastern Railway. They were intended for use as powerful shunting engines to arrange and move coal wagons for loading into ships. In total 15 were built, 10 by the NER between 1909 and 1910, and a further five in 1925 by the London and North Eastern Railway (LNER). They had three cylinders with divided drive: the inside cylinder driving the leading axle, the outside cylinders driving the centre. Overview The reversing gear was originally mechanical, but was replaced on all but two of the locomotives (nos. 1355/8) by steam-operated reversing gear between 1932 and 1934. The steam reversing gear was removed again between 1941 and 1947. In 1929, No. 1656 was moved to the newly built Whitemoor Yard at March, Cambridgeshire. In 1932, this locomotive was replaced by Nos. 1355 and 1358. Whitemoor preferred the ex-GCR 0-8-4T ( LNER Class S1) for hump shunting, so in 1934 No 1 ...

North Eastern Railway (UK)
The North Eastern Railway (NER) was an English railway company. It was incorporated in 1854 by the combination of several existing railway companies. Later, it was amalgamated with other railways to form the London and North Eastern Railway at the Grouping in 1923. Its main line survives to the present day as part of the East Coast Main Line between London and Edinburgh. Unlike many other pre-Grouping companies the NER had a relatively compact territory, in which it had a near monopoly. That district extended through Yorkshire, County Durham and Northumberland, with outposts in Westmorland and Cumberland. The only company penetrating its territory was the Hull & Barnsley, which it absorbed shortly before the main grouping. The NER's main line formed the middle link on the Anglo-Scottish "East Coast Main Line" between London and Edinburgh, joining the Great Northern Railway near Doncaster and the North British Railway at Berwick-upon-Tweed. Although primarily a Northern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NER Class D
The North Eastern Railway Class D (later London and North Eastern Railway (LNER) Class H1) was a class of 4-4-4T three-cylinder side tank steam locomotive designed by Vincent Raven in 1913. They were used for rural passenger services. Forty five were built in total; a first batch of twenty, then a further twenty five after the War. Between 1931 and 1936, all of the LNER H1 class were rebuilt with a 4-6-2T 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.

NER Class Y
The North Eastern Railway (NER) Class Y (LNER Class A7) 4-6-2T tank locomotives were designed whilst Wilson Worsdell was Chief Mechanical Engineer, but none were built until 1910 by which time Vincent Raven had taken over. Overview The Class Y locomotives were intended for hauling coal trains and were developed from the NER Class X (LNER Class T1) 4-8-0T heavy shunters. However, they had larger boilers and smaller cylinders for higher working speeds. Twenty were built in one batch and numbered between 1113 and 1195. Originally built with saturated boilers pressed to , seven locomotives were later fitted with boilers equipped with superheaters and pressed to . All twenty locomotives passed to the London and North Eastern Railway at the 1923 Grouping. The LNER left the NER's locomotive numbers unchanged, but raised the boiler pressure of the saturated locomotives to . They also fitted ten more locomotives with the 160 lbf/in2 superheated boilers that the LNER classified as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vincent Raven
Sir Vincent Litchfield Raven, KBE (3 December 1859 – 14 February 1934) was an English railway engineer, and was chief mechanical engineer of the North Eastern Railway from 1910 to 1922. Biography Vincent Raven was born the son of a clergyman at Great Fransham rectory in Norfolk and educated at Aldenham School in Hertfordshire. In 1877 he began his career with the North Eastern Railway as a pupil of the then Locomotive Superintendent, Edward Fletcher. By 1893 he had achieved the post of Assistant Mechanical Engineer to Wilson Worsdell who was then the Locomotive Superintendent. In this post he was involved for the first time with an electrification project, as the N.E.R. was electrifying the North Tyneside suburban route in 1904. This was a third rail system at 600 volts DC. Steam locomotives In 1910 he became Chief Mechanical Engineer on Wilson Worsdell's retirement (The title of the post had changed from Locomotive Superintendent in 1902).
