LNER Class N4
The Great Central Railway (GCR) Class 9A was a class of 0-6-2T steam locomotive built between 1889 and 1892. From 1923 the locomotives were redesignated Class N4. Design and construction Designed by Thomas Parker (engineer), Thomas Parker for the Manchester, Sheffield and Lincolnshire Railway (MS&LR), a total of 55 locomotives were constructed up to 1892. The MS&LR changed its name to the GCR in 1897. In 1892 the final fourteen locomotives were built with a larger coal bunker, increasing their weight to . This last batch was classified as Class 9A Altered, sometimes abbreviated as 9A Alt. The GCR 9A locos were reclassified as N4 under the LNER locomotive numbering and classification system when the GCR was absorbed into the London and North Eastern Railway after the Railways Act 1921, 1923 grouping. The original design were N4/1 and those with extended bunkers N4/2. In 1925, shorter chimneys began to be fitted to bring the N4s within the LNER composite loading gauge, creating tw ...

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, oil or, rarely, wood) to heat water in the locomotive's 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 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 coupled to it. 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 during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Railway Locomotives Introduced In 1889
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ...

Great Central Railway Locomotives
This is a list of locomotives and rolling stock based at the preserved Great Central Railway at Loughborough, Leicestershire, the Great Central Railway (Nottingham) in Ruddington and the Mountsorrel Railway near Leicester. Mainline steam locomotives The Great Central has a varied fleet of steam classes representing each of the United Kingdom's " Big Four" railway companies and British Rail. Some of them once worked along the original routes, and others were part of classes that saw service there. Operational Non operational Under overhaul/construction Stored Industrial locomotives Industrial steam locomotives Industrial steam locomotives became the mainstay of steam power in early British railway preservation before the Barry Scrapyard veterans were fully restored. Many have huge traction efforts despite their small sizes, making them more than capable of hauling large passenger trains.

Railways Act 1921
The Railways Act 1921 (c. 55), also known as the Grouping Act, was an Act of Parliament enacted by the British government and intended to stem the losses being made by many of the country's 120 railway companies, by "grouping" them into four large companies dubbed the " Big Four". This was intended to move the railways away from internal competition, and retain some of the benefits which the country had derived from a government-controlled railway during and after the Great War of 1914–1918. The provisions of the Act took effect from the start of 1923. History The British railway system had been built up by more than a hundred railway companies, large and small, and often, particularly locally, in competition with each other. The parallel railways of the East Midlands and the rivalry between the South Eastern Railway and the London, Brighton and South Coast Railway at Hastings were two examples of such local competition. During the First World War the railways were under st ...

LNER Locomotive Numbering And Classification
A number of different numbering and classification schemes were used for the locomotives owned by the London and North Eastern Railway (LNER) and its constituent companies. This page explains the principal systems that were used. The following abbreviations for the constituent companies are used on this page: * ''Principal Constituents'' Great Central Railway (GCR), Great Eastern Railway (GER), Great Northern Railway (GNR), Great North of Scotland Railway (GNoSR), Hull and Barnsley Railway (HBR), North British Railway (NBR), and North Eastern Railway (NER) * ''Minor Companies'' (absorbed between July 1923 and July 1924) Colne Valley and Halstead Railway (CV&HR), East and West Yorkshire Union Railway (E&WYUR), and Mid-Suffolk Light Railway (MSLR) * ''Later Additions'' Midland and Great Northern Joint Railway (M&GNJR) - absorbed October 1936 Ex- Metropolitan Railway steam locomotives (via the London Passenger Transport Board) - absorbed November 1937 * For information ab ...

British Railways
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997. It was formed from the nationalisation of the Big Four British railway companies, and was privatised in stages between 1994 and 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. The period of nationalisation saw sweeping changes in the railway. A process of dieselisation and electrification took place, and by 1968 steam locomotives had been entirely replaced by diesel and electric traction, except for the Vale of Rheidol Railway (a narrow-gauge tourist line). Passengers replaced freight as the main source of business, and one-third of the network was closed by the Beeching cuts of the 1960s in an effort to reduce rail subsidies. On privatis ...

London And North Eastern Railway
The London and North Eastern Railway (LNER) was the second largest (after LMS) of the " 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, North Eastern Region, and partially the Scottish Region. History The company was the second largest created by the Railways Act 1921. The principal constituents of the LNER were: * Great Eastern Railway * Great Central Railway * Great Northern Railway * Great North of Scotland Railway * Hull and Barnsley Railway * North British Railway * North Eastern Railway The total route mileage was . The North Eastern Railway had the largest route mileage of , whilst the Hull and Barnsley Railway was . It covered the area north and east of London. It included the East Coast Main Line from London to Edinburgh via York and Newcastle upon Tyne and the routes from Edinburgh to ...
