GWR 3511 Class
The GWR 3511 class were standard gauge locomotives designed by William Dean for the Great Western Railway and built in 1885. History They comprised the last ten of the twenty locomotives of Lot 64. The first ten locomotives of this Lot were built to the broad gauge as the 3501 class. Use Originally built with condensing apparatus they were used on work through the Severn Tunnel until the ventilation was improved. Rebuilding The condensing apparatus was soon removed and in 1894/5 they were all rebuilt as tender locomotive A tender or coal-car (US only) is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water.

Great Western Railway
The Great Western Railway (GWR) was a British railway company that linked London with the southwest, west and 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 amalgamations saw it also operate 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 amalgamated it with the remaining independent railways within its territory, and it was finally merged at the end of 1947 when it was nationalised and became the Western Region of British Railways. The GWR was called by some "God's Wonderful Railway" and by others the "Great Way Round" but it was famed as the "Holiday ...

Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Dean (engineer)
William Dean (8 January 1840 – 24 September 1905) was an English railway engineer. He was the second son of Henry Dean, who was the manager of the Hawes Soap Factory in New Cross, London. William was educated at the Haberdashers' Company School. He became the Chief Locomotive Engineer for the Great Western Railway from 1877, when he succeeded Joseph Armstrong (engineer), Joseph Armstrong. He retired from the post in 1902 and was replaced by George Jackson Churchward. He designed famous steam locomotive classes such as the GWR 3252 Class, Duke Class, the GWR 3300 Class, Bulldog Class and the long-lived GWR 2301 Class, 2301 Class. Apprenticeship He was apprenticed at the age of fifteen to Joseph Armstrong at the Great Western Railway's Wolverhampton Wolverhampton railway works, Stafford Road Works. During his eight-year apprenticeship he attended Wolverhampton Working Men's College in the evening, excelling in mathematics and engineering. Upon completion of his apprentice years ...

Broad Gauge
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the used by standard-gauge railways. Broad gauge of , commonly known as Russian gauge, is the dominant track gauge in former Soviet Union (CIS states, Baltic states, Georgia and Ukraine), Mongolia and Finland. Broad gauge of , commonly known as Irish Gauge, is the dominant track gauge in Ireland, and the Australian states of Victoria and Adelaide. Broad gauge of , commonly known as Iberian gauge, is the dominant track gauge in Spain and Portugal. Broad gauge of , commonly known as Indian gauge, is the dominant track gauge in India, Pakistan, Bangladesh, Sri Lanka, Argentina, Chile, and on BART (Bay Area Rapid Transit) in the San Francisco Bay Area. This is the widest gauge in common use anywhere in the world. It is possible for trains on both Iberian gauge and Indian gauge to travel on each other's tracks with no modifications in the vast majority of cases. History In Gr ...

GWR 3501 Class
The GWR 3501 Class were ten broad gauge locomotives built by the Great Western Railway. They were built in 1885 as locomotives, but five were rebuilt in 1890 as tender locomotives for working express trains between Exeter and Plymouth. They comprised the first ten locomotives of Lot 64, the remainder of which comprised ten similar locomotive Nos. 3511 to 3520 built to the standard gauge. In 1892 the broad gauge was abandoned and the locomotives were all converted to standard gauge A standard-gauge railway is a railway with a track gauge of .

Condensing Steam Locomotive
A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat exchanger, into the boiler water tanks. Installations vary depending on the purpose, design and the type of locomotive to which it is fitted. It differs from the usual closed cycle condensing steam engine, in that the function of the condenser is primarily either to recover water, or to avoid excessive emissions to the atmosphere, rather than maintaining a vacuum to improve both efficiency and power. Thermodynamics Unlike the surface condenser often used on a steam turbine or marine steam engine, the condensing apparatus on a steam locomotive does not normally increase the power output, rather it decreases due to a reduction of airflow to th ...

Severn Tunnel
The Severn Tunnel ( cy, Twnnel Hafren) is a railway tunnel in the United Kingdom, linking South Gloucestershire in the west of England to Monmouthshire in south Wales under the estuary of the River Severn. It was constructed by the Great Western Railway (GWR) between 1873 and 1886 for the purpose of dramatically shortening the journey times of their trains, passenger and freight alike, between South Wales and Western England. It has often been regarded as the crowning achievement of GWR's chief engineer Sir John Hawkshaw. Prior to the tunnel's construction, lengthy detours were necessary for all traffic between South Wales and Western England, which either used ship or a lengthy diversion upriver via . Recognising the value of such a tunnel, the GWR sought its development, tasking Hawkshaw with its design and later contracting the civil engineer Thomas A. Walker to undertake its construction, which commenced in March 1873. Work proceeded smoothly until October 1879, at which poi ...

Tender Locomotive
A tender or coal-car (US only) is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board the locomotive itself are called tank locomotives. A corridor tender is a locomotive tender with a passageway to one side, allowing crew changes on the fly. A brake tender is a tender that is heavy and used (primarily) to provide greater braking efficiency. General functions The largest steam locomotives are semi-permanently coupled by a drawbar to a tender that carries the water and fuel. The fuel source used depends on what is economically available locally. In the UK and parts of Europe, a plentiful supply of coal made ...

GWR 3201 Class
The 3201 or Stella Class was a class of standard gauge steam locomotive, designed by William Dean and built at Swindon Works for the Great Western Railway in 1884 and 1885. Design They were part of a standardisation scheme of Dean's, whereby he designed four classes with similar boilers, double frames, and cylinders, but of different wheel layouts. The 3201 class was close in design to the 3501 Class, ten of which were built initially as "convertibles" for the broad gauge, and numbers 3511 to 3520 built as standard gauge condensing s. Construction Initially there were 5 members of the class. The prototype, No.3201, built in December 1884, was immediately sold to the Pembroke and Tenby Railway, who named it ''Stella''. It returned to the GWR in 1896 and retained the nameplates until 1902. Nos. 3202-3205 were constructed in the summer of 1885. Between 1892 and 1895 the class was enlarged to 25 locomotives, as the broad and standard gauge 2-4-0Ts were all eventually c ...

Steam Locomotives Of Great Britain
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...
