NBR D Class 0-6-0T
The NBR D Class (LNER Class J83) was a class of 0-6-0 tank locomotives designed by Matthew Holmes for short distance freight, station pilot, and heavy shunting duties on the North British Railway. Service history They were introduced in 1900 and had inside cylinders and piston valves operated by Stephenson valve gear. Forty of these new Class D engines were delivered in 1900–01, twenty each from Neilson and Company and Sharp, Stewart and Company. At grouping they became LNER class J83. The class were highly successful in service, with only three failing to complete during their lifetime. One locomotive, No. 9830, managed to complete . The engines were commonly seen across the entire North British Railway network, and were the second largest class of tank engines on the railway, after the NBR A class. Numbering On the NBR they were numbered in a sequence commencing with 795 (and are sometimes referenced as 795 class engines). A total of 40 locomotives were built, all b ...

Matthew Holmes (engineer)
Matthew Holmes (born in Paisley in 1844 and died in Lenzie on 3 July 1903) was Locomotive Superintendent of the North British Railway from 1882 to 1903. The office had two deputies, the senior known as ''Assistant Locomotive Superintendent and Chief Draughtsman'', the junior known as ''Assistant Locomotive Superintendent''. Throughout his incumbency, Holmes's Assistant Locomotive Superintendent and Chief Draughtsman was Robert Chalmers. Various men held the position of Assistant Locomotive Superintendent, the last to do so being William Paton Reid. Holmes was succeeded in office by Reid. Later, Reid was to be succeeded by Robert Chalmers' son, Walter. Locomotive Designs Locomotives designed by Holmes include: * NBR Class C, later LNER Class J36 0-6-0, * NBR D class 0-6-0T, later LNER Class J83 0-6-0T * NBR Class M, later LNER Class D31 4-4-0 * NBR D class 0-6-0 * See also * Locomotives of the North British Railway The North British Railway was opened in 1846 as the line ...

Piston Valve (steam Engine)
Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power. The valve consists of two piston heads on a common spindle moving inside a steam chest, which is essentially a mini-cylinder located either above or below the main cylinders of the locomotive. Overview In the 19th century, steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * It is difficult to lubricate slide valves adequately in the presence of superheated steam * With piston valves, the steam passages can be made shorter. This, particularly following the work of André Chapelon, reduces resistance to the flow of steam and improves eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Locomotives Introduced In 1900
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North British Railway Locomotives
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

OO Gauge
OO gauge or OO scale (also, 00 gauge and 00 scale) is the most popular standard-gauge model railway standard in the United Kingdom, outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards (4 mm to 1 foot, or 1:76.2), and the only one to be marketed by major manufacturers. The OO track gauge of (same as H0 scale) corresponds to prototypical gauge of , rather than standard gauge. However, since the 1960s, other gauges in the same scale have arisen—18.2 mm (EM) and 18.83 mm (Scalefour)—to reflect the desire of some modellers for greater scale accuracy. Origin Double-0 scale model railways were launched by Bing in 1921 as "The Table Railway", running on track and scaled at 4 mm-to-the-foot. In 1922, the first models of British prototypes appeared. Initially all locomotives were powered by clockwork, but the first electric power appeared in autumn 1923. OO describes models with a scale of 4 mm = 1 foot (1:76) runnin ...

Hornby Railways
Hornby Railways is a British rail transport modelling, model railways manufacturing company. Its roots date back to 1901 in Liverpool, when founder Frank Hornby received a patent for his Meccano construction toy. The first clockwork train was produced in 1920. In 1938, Hornby launched its first 00 gauge train. In 1964, Hornby and Meccano were bought by their competitor, Tri-ang, and sold when Tri-ang went into receivership. Hornby Railways became independent again in the 1980s, and became listed on the London Stock Exchange, but due to financial troubles reported in June 2017, became majority owned by British turnaround specialist Phoenix Asset Management. Apart from trains, Hornby also commercialises model cars and other vehicles through its brands Bassett-Lowke, Corgi Toys, Corgi, Jouef, Lima (models), Lima, Pocher, and Scalextric. History Early history: 1920–1938 Hornby was at first a tradename for the railway productions of Meccano Ltd and based around Liverpool. U ...

British Rail
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 ...

NBR A Class
The NBR A Class ( London and North Eastern Railway (LNER) Classes N14 and N15 were the standard 0-6-2 tank locomotives designed by William P. Reid for freight duties on the North British Railway. The LNER regarded the original locomotives as two separate classes (N14 & N15). The final batch of locomotives was on order at the time of the grouping in 1923. History N14 Class The original six locomotive introduced in 1909 and had inside cylinders and piston valves operated by Stephenson valve gear, and weighed . They were built by the North British Locomotive Company and numbered 858-863. They were withdrawn 1947-1954. N15/1 Class Fifty three similar locomotives were built by the North British Locomotive Company between June 1910 March 1917 with longer cabs but shorter bunkers. They were fitted with Steam brakes and used on Freight duties. A further batch of ten locomotives was built by North British Locomotive Company in February and March 1920. A third batch of ten was on ord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Four (British Railway Companies)
"Big Four" was a name used to describe the four largest railway companies in the United Kingdom in the period 1923–1947. The name was coined by ''The Railway Magazine'' in its issue of February 1923: "The Big Four of the New Railway Era". The Big Four were: * Great Western Railway (GWR) * London, Midland and Scottish Railway (LMS) * London and North Eastern Railway (LNER) * Southern Railway (SR) The companies were formed as a result of the Railways Act 1921, in a process known as "The Grouping" (of the railways), which came into effect on 1 January 1923. On 1 January 1948 the companies were nationalised to form British Rail, British Railways as a result of the Transport Act 1947. Characterisation The three larger companies relied heavily on freight (especially coal), as well as long-distance passenger traffic. The Southern Railway, in contrast, was predominantly a passenger railway, which, despite its small size, carried more than a quarter of the total UK passenger tra ...
