GWR 655 Class
Class 655 of the Great Western Railway The Great Western Railway (GWR) was a British railway company that linked London London is the capital and List of urban areas in the United Kingdom, largest city of England and the United Kingdom, with a population of just under 9 mill ... was a class of 52 locomotives designed by George Armstrong and built at the GWR's Wolverhampton Works. Design and construction They were built in three lots between 1892 and 1897: * Nos. 655, 767 and 1741-1750 (Lot A3, 1892) * Nos. 1771-1790 (Lot B3, 1892-4) * Nos. 2701-2720 (Lot E3, 1896-7) They were in effect a continuation of the 645 Class, with longer frames though using the same 4'6" wheels and 15'6" wheelbase, and they were the last of the larger type of tank engine to be built at Wolverhampton. Pannier tanks were later fitted to all of them, apart from No. 1772, between 1912 and 1930. Use They were nearly all Northern Division engines until the 1920s, though later Weymouth had ...

George Armstrong (engineer)
George Armstrong (5 April 1822 – 11 July 1901) was an English railway engineer. He was in charge of standard gauge steam locomotives for the Great Western Railway at Stafford Road Works, Wolverhampton, from 1864 to 1897. He was the younger brother of his colleague Joseph Armstrong, but thanks to the special requirements of the GWR at a time when it was split in two by the broad and standard gauges, the brothers were able to work largely independently of each other. George is best remembered for his 0-4-2 and 0-6-0 tank engines; these were long-lived, and even when life-expired they were replaced by Collett and Hawksworth with remarkably similar locomotives, the well-known 1400, 5700 and 1600 classes. Biography George Armstrong was born on 5 April 1822. His gravestone states that the place was Bewcastle, Cumberland, and this information is repeated by Marshall. However, Holcroft writes that the family went to Canada in 1817, not returning until 1824, and that consequent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolverhampton Railway Works
Wolverhampton railway works was in the city of Wolverhampton in the county of Staffordshire, England. It was almost due north of the city centre, and is commemorated with a small display of level crossing gates and a plaque. Known as the Stafford Road Works, it was opened by the Shrewsbury and Birmingham Railway in 1849 to maintain bought-in locomotives. Overview Wolverhampton works, located at Gorsebrook, north of Wolverhampton centre, became the workshop of the Northern Division of the Great Western Railway in 1854 under Joseph Armstrong (engineer), Joseph Armstrong who had been in charge of maintenance for the Shrewsbury and Chester Railway at Saltney. The first line arrived at Wolverhampton and the running shed was rebuilt. Locomotive repairs were concentrated in Wolverhampton, while carriage and wagon work was transferred to Saltney. Locomotives Joseph Armstrong was promoted to Swindon railway works, Swindon in 1864 and his brother George Armstrong (engineer), George s ...

Great Western Railway
The Great Western Railway (GWR) was a British railway company that linked London London is the capital and List of urban areas in the United Kingdom, largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary dow ... with the southwest, west and West Midlands (region), West Midlands of England and most of Wales. It was founded in 1833, received its enabling Act of Parliament on 31 August 1835 and ran its first trains in 1838 with the initial route completed between London and Bristol in 1841. It was engineered by Isambard Kingdom Brunel, who chose a broad gauge of —later slightly widened to —but, from 1854, a series of Consolidation (business), amalgamations saw it also operate Standard gauge, standard-gauge trains; the last broad-gauge services were operated in 1892. The GWR was the only company to keep its identity through the Railways Act 1921, which ama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as stratum, rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * Engine displacement Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of t ... References {{Steam engine configurations Engine technology ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...

GWR 645 Class
The GWR 645 Class was a class of designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six were constructed between 1872-3, of which three were built for the South Wales Mineral Railway (SWMR), two for the Carmarthen and Cardigan Railway (C&CR) and the remainder for the GWR. In essence, they were saddle tank versions of his GWR 633 Class of 1871. From 1878, a further 72 of the class, partially enlarged, were added in the 1501 numbering sequence. Unlike the originals, the "1501"s had full-length saddle tanks from the start. Construction The whole class was delivered in nine lots, as follows: * 645-655, plus one (Lot O, 1872) * 656, 757-763, plus four (Lot P, 1872-3) * 764-775 (Lot Q, 1873) * 1501-1512 (Lot A2, 1878) * 1513-1524 (Lot B2, 1878-9) * 1525-1536 (Lot D2, 1879) * 1537-1548 (Lot E2, 1879–80) * 1549-60 (Lot F2, 1880) * 1801-1812 (Lot G2, 1881) Three of the un-numbered engines plus No. 767 were sold to the ...

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), Big Four British railway companies, and was privatisation of British Rail, 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 Railway electrification in Great Britain, 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 railway, narrow-gauge tourist line). Passenger train, Passengers replaced freight train, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Correspondence And Travel Society
The Railway Correspondence and Travel Society (RCTS) is a national society founded in Cheltenham, England in 1928 to bring together those interested in rail transport and locomotives. Since 1929 the Society has published a regular journal ''The Railway Observer'' which records the current railway scene. It also has regional branches which organise meetings and trips to places of interest and an archive & library. It has published definitive multi-volume locomotive histories of the Great Western, Southern and London & North Eastern Railways, and has in progress similar works on the London, Midland & Scottish Railway and British Railways standard steam locomotives. It also has published many other historical railway books since the mid-1950s. On 2 November 2016, the RCTS become a Charitable Incorporated Organisation (CIO), registered number 1169995.
