GER Class S69
The Great Eastern Railway (GER) Class S69, also known as 1500 Class, and later classified B12 by the London and North Eastern Railway (LNER) is a class of 4-6-0 steam locomotive designed to haul express passenger trains from London Liverpool Street station along the Great Eastern Main Line. Originally they were designed by S. D. Holden, but were much rebuilt, resulting in several subclasses. Seventy-one S69 locomotives were built between 1911 and 1921 and numbered 1500–1570. Fifty-one of these were built at the GER's Stratford Works and the remaining 20 by William Beardmore and Company. A further 10 locomotives were built by Beyer, Peacock and Company for the LNER in 1928 and numbered 8571–8580. From 1948 the British Railways numbers were 61500–61580 (with gaps). Background At the time of their introduction, the "Claud Hamilton" 4-4-0s were becoming outclassed on the heaviest express. Although an enlarged 4-4-0 design was mooted, it was realised that any such design wou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratford Works
Stratford Works was the locomotive-building works of the Great Eastern Railway situated at Stratford, London, England. The original site of the works was located in the 'V' between the Great Eastern Main Line and the Stratford to Lea Bridge route and in the early years was also the home of Stratford Locomotive Depot. The final part of the works closed in 1991. Overall Stratford works built 1,702 locomotives; 5,500 passenger vehicles and 33,000 goods wagons (although a significant number of these were built at the nearby Temple Mills wagon works when wagon building moved from the Stratford site in 1896). History Early history (1840-1862) Activity on the site was started in 1840 by the Northern and Eastern Railway who had opened a new line that joined the Eastern Counties Railway at Stratford. The locomotives were maintained at a roundhouse called the Polygon which was built between July and September 1840 to a design by Robert Stephenson (a surviving example of which can be ...

Axle Load
An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type axle is referred to as a '' spindle''. Terminology On cars and trucks, several senses of the word ''axle'' occur in casual usage, referring to the shaft itself, its housing, or simply any transverse pair of wheels. Strictly speaking, a shaft which rotates with the wheel, being either bolted or splined in fixed relation to it, is called an ''axle'' or ''axle shaft''. However, in looser usage, an entire assembly including the surrounding axle housing (typically a casting) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LNER Class J20
The GER Class D81 was a class of twenty-five 0-6-0 steam locomotives designed by A. J. Hill for the Great Eastern Railway. The all passed to the London and North Eastern Railway at the 1923 grouping and received the classification J20. History These locomotives were fitted with cylinders and wheels, while the Belpaire firebox-fitted boiler was identical to that fitted to the Class S69 4-6-0s. They were the most powerful 0-6-0 tender locomotive in Britain until the arrival of Oliver Bulleid Oliver Vaughan Snell Bulleid CBE (19 September 1882 – 25 April 1970) was a British railway and mechanical engineer best known as the Chief Mechanical Engineer (CME) of the Southern Railway between 1937 and the 1948 nationalisation, d ...'s Q1 class for the Southern Railway in 1942. All were still in service at the 1923 grouping, the LNER adding 7000 to the numbers of nearly all the ex-Great Eastern locomotives, including the Class D81 locomotives. Between 1943 and 195 ...

Inverurie Locomotive Works
Inverurie Locomotive Works was created in 1902 when the Great North of Scotland Railway (GNSR) moved their works from Kittybrewster, in Aberdeen about to Inverurie. History The Great North of Scotland Railway constructed its locomotive construction and repair works on a site at Inverurie north west of Aberdeen, beside Inverurie railway station and the line to Keith. Only ten locomotives were ever built at the Works. These locomotives which were 4-4-0 tender engines of GNSR classes V and F were manufactured between 1906 and 1921. Although there were differences between the V and F engines, for example the F class were superheated, the London and North Eastern Railway counted members of both classes as LNER Class D40. The works remained open for locomotive repair throughout London and North Eastern Railway and into British Railways ownership, finally closing in 1969. The name is carried on by the local community in the form of Inverurie Loco Works FC, a part-time Scottish s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great North Of Scotland Railway
The Great North of Scotland Railway (GNSR) was one of the two smallest of the five major Scottish railway companies prior to the 1923 Grouping, operating in the north-east of the country. Formed in 1845, it carried its first passengers the from Kittybrewster, in Aberdeen, to Huntly on 20 September 1854. By 1867 it owned of line and operated over a further . The early expansion was followed by a period of forced economy, but in the 1880s the railway was refurbished, express services began to run and by the end of that decade there was a suburban service in Aberdeen. The railway operated its main line between Aberdeen and and two routes west to , connections could be made at both Keith and Elgin for Highland Railway services to Inverness. There were other junctions with the Highland Railway at and , and at Aberdeen connections for journeys south over the Caledonian and North British Railways. Its eventual area encompassed the three Scottish counties of Aberdeenshire, Banf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppet Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of the Newcastle and Frenchtown Railroad. Young had patented his idea, but the Patent Office fire of 1836 destroyed all records of it. Etymology The word ...

Hugo Lentz
Hugo Lentz (1859–1944) was an Austrian mechanical engineer, born in South Africa. He was the inventor of many award-winning improvements to the steam engine. The correct spelling of his name is Lenz but it has been Anglicised to Lentz in English-speaking countries. Life and career Lentz was born on 21 July 1859 in South Africa. When he was six years old, his father died and the family returned to relatives in Germany. He became an engineer in the Prussian Navy. In 1888, Lentz founded his own machine factory in Vienna. At an exposition in honour of Alessandro Volta in Como in 1899, his first steam engine won the first prize. At the Exposition Universelle (1900) in Paris, it won the ''Grand Prix'' while Lentz himself was awarded the gold medal. From 1907, ''Davey, Paxman & Co'', [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ACFI Feedwater Heater
A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system.Fundamentals of Steam Power by Kenneth Weston, University of Tulsa This reduces plant operating costs and also helps to avoid to the boiler metal when the feedwater is introduced back into the steam cycle.

Sevenoaks Railway Accident
The Sevenoaks railway accident occurred on 24 August 1927 between Dunton Green railway station and Sevenoaks railway station. The Southern Railway's afternoon express from Cannon Street to Deal left London at 5 pm, hauled by River Class tank engine No 800 ''River Cray''. Several passengers later recounted that from time to time the train seemed to roll excessively on fast curves. As it passed through Pollhill Tunnel at 60 mph the rocking became violent and the train derailed past Dunton Green railway station, where the line is in a cutting which is spanned by a bridge carrying Shoreham Lane. The cab of the locomotive struck the bridge and the engine was turned on its side across the cutting. The leading coaches piled up against it, killing 13 and injuring many more. Railway engineer Brigadier-General Archibald Jack was a survivor of the crash. John Wallace Pringle, Chief Inspecting Officer of Her Majesty's Railway Inspectorate conducted the inquiry in person.

2-6-4T
Under the Whyte notation for the classification of steam locomotives, a locomotive has two leading wheels, six coupled driving wheels and four trailing wheels. This arrangement is commonly called Adriatic. Overview With only a few known exceptions, the Adriatic wheel arrangement was usually used on tank locomotives, for which various suffixes to indicate the type of tank would be added to the wheel arrangement, for example for an engine with side-tanks. Tender locomotives The earliest known example was the South African Class 6Z, designed by Cape Government Railways (CGR) Chief Locomotive Superintendent Hazlitt Beatty in 1901. The first engines of the class were modified 2-6-2 Prairie locomotives which were equipped with two-axle trailing bogies. In 1902, more were placed in service, but built with the wheel arrangement. The latter were the first known tender locomotives in the world to be built with this wheel arrangement.Neilson, Reid works list, compiled by Austrian lo ...
