Divided Drive (locomotive)
A divided drive locomotive is a steam locomotive that divides the driving force on its wheels by using different cylinder (locomotive), cylinders to power different pairs of driving wheels in order to give better weight distribution and reduce "hammer blow" which can be damaging to the track, or else to enable the wider spacing of the driving wheels to accommodate a larger firebox. Origins Anatole Mallet The system of dividing drive was originally developed by Anatole Mallet in the 1870s on a number of rigid-wheelbase compound locomotives, and then during the 1880s, on Mallet locomotive, Mallet articulated locomotives. Francis Webb Mallet's ideas inspired Francis Webb (engineer), Francis Webb in Britain who introduced 2-(2-2)-0, 2-(2-2)-2, 2-2-2-2T, 2-2-(4-0)T divided drive locomotives between 1882 and 1903. Alfred de Glehn Alfred de Glehn introduced a successful divided drive 2-(2-2)-0 compound based on Webb's ideas. Use in the United Kingdom Dugald Drummond of the London and S ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, Fuel oil, oil or, rarely, Wood fuel, wood) to heat water in the locomotive's Boiler (power generation), boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its Steam locomotive components, cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a Tender (rail), tender coupled to it. #Variations, Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom of Great Britain an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LSWR E10 Class
The London and South Western Railway (LSWR, sometimes written L&SWR) was a railway company in England from 1838 to 1922. Originating as the London and Southampton Railway, its network extended to Dorchester and Weymouth, to Salisbury, Exeter and Plymouth, and to Padstow, Ilfracombe and Bude. It developed a network of routes in Hampshire, Surrey and Berkshire, including Portsmouth and Reading. The LSWR became famous for its express passenger trains to Bournemouth and Weymouth, and to Devon and Cornwall. Nearer London it developed a dense suburban network and was pioneering in the introduction of a widespread suburban electrified passenger network. It was the prime mover of the development of Southampton Docks, which became an important ocean terminal as well as a harbour for cross channel services and for Isle of Wight ferries. Although the LSWR's area of influence was not the home of large-scale heavy industry, the transport of goods and mineral traffic was a major activity, ...

London And North Eastern Railway
The London and North Eastern Railway (LNER) was the second largest (after London, Midland and Scottish Railway, LMS) of the "Big Four (British railway companies), Big Four" railway companies created by the Railways Act 1921 in Britain. It operated from 1 January 1923 until nationalisation on 1 January 1948. At that time, it was divided into the new British Railways' Eastern Region of British Railways, Eastern Region, North Eastern Region of British Railways, North Eastern Region, and partially the Scottish Region of British Railways, Scottish Region. History The company was the second largest created by the Railways Act 1921. The principal List of constituents of the London and North Eastern Railway, constituents of the LNER were: * Great Eastern Railway * Great Central Railway * Great Northern Railway (Great Britain), Great Northern Railway * Great North of Scotland Railway * Hull and Barnsley Railway * North British Railway * North Eastern Railway (UK), North Eastern Railw ...

Sir Nigel Gresley
Sir Herbert Nigel Gresley (19 June 1876 – 5 April 1941) was a British railway engineer. He was one of Britain's most famous steam locomotive engineers, who rose to become Chief Mechanical Engineer (CME) of the London and North Eastern Railway (LNER). He was the designer of some of the most famous steam locomotives in Britain, including the GNR Class A1, LNER Class A1 and LNER Class A4 Whyte notation, 4-6-2 4-6-2, Pacific engines. An A1 Pacific, ''LNER Class A3 4472 Flying Scotsman, Flying Scotsman'', was the first steam locomotive officially recorded over 100 mph in passenger service, and an A4, No. 4468 ''LNER Class A4 4468 Mallard, Mallard'', still holds the record for being the fastest steam locomotive in the world (126 mph). Gresley's engines were considered elegant, both aesthetically and mechanically. His invention of a three-cylinder design with only two sets of Walschaerts valve gear, the Gresley conjugated valve gear, produced smooth running and power at ...

SR Lord Nelson Class
The SR class LN or ''Lord Nelson'' class is a type of 4-cylinder 4-6-0 steam locomotive designed for the Southern Railway by Richard Maunsell in 1926. They were intended for Continental boat trains between London (Victoria) and Dover harbour, but were also later used for express passenger work to the South-West of England. Sixteen of them were constructed, representing the most powerful (although not the most successful) Southern 4-6-0 design. They were all named after famous admirals. The class continued to operate with British Railways until withdrawn during 1961 and 1962. Only one example of the class – the first engine, ''Lord Nelson'' itself – has been saved from scrapping. This has been seen running on mainline tours and preserved railways throughout Britain. Background Although the improved ”King Arthur" class 4-6-0 locomotives were capable of the heaviest express passenger work between London and South West England, there was a growth in demand for Continental ...

Southern Railway (Great Britain)
The Southern Railway (SR), sometimes shortened to 'Southern', was a British railway company established in the 1923 Grouping. It linked London with the Channel ports, South West England, South coast resorts and Kent. The railway was formed by the amalgamation of several smaller railway companies, the largest of which were the London and South Western Railway (LSWR), the London, Brighton and South Coast Railway (LB&SCR) and the South Eastern and Chatham Railway (SE&CR).Bonavia (1987) pp. 26–28 The construction of what was to become the Southern Railway began in 1838 with the opening of the London and Southampton Railway, which was renamed the London & South Western Railway. The railway was noted for its astute use of public relations and a coherent management structure headed by Sir Herbert Walker. At , the Southern Railway was the smallest of the "Big Four" railway companies, the only one to operate entirely in England, and, unlike the others, the majority of its reven ...

North Eastern Railway (UK)
The North Eastern Railway (NER) was an England, English rail transport, 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 Railways Act 1921, 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, England, 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 (Great Britain), Great Northern Railwa ...

Switcher
A switcher locomotive (American English), shunter locomotive (British English), station pilot (British English), or shifter locomotive (Pennsylvania Railroad terminology) is a locomotive used for maneuvering railway vehicles over short distances. Switchers do not usually move trains over long distances. Instead, they typically assemble trains in order for another locomotive to take over. Switchers often operate in a railyard or make short transfer runs. They may serve as the primary motive power on short branch lines or switching and terminal railroads. A hybrid type known as a road switcher can both shunt and haul trains. Switchers are optimized for their role, being relatively low-powered but with a high starting tractive effort for getting heavy cars rolling quickly. Switchers are geared to produce high torque but are restricted to low top speeds and have small diameter driving wheels. Switchers tend to be durable and to remain in service for a long time, such as the SJ U, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 135 ...
