GWR 7 (Armstrong) Class
The William Dean 7 or Armstrong Class refers to a group of four prototype 4-4-0 double-frame locomotives built at the Swindon Works of the 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 ... in 1894. History They were nominal renewals of four of Dean's "experimental locomotives", Nos. 7, 8, 14 and 16. Had it not been for the recent derailing of one of his 3001 Class 2-2-2s in Box Tunnel, these engines would probably have been rebuilt as 2-2-2s; in the event they emerged as double-framed four-coupled engines with 7' driving wheels and a front bogie similar to that used on the 3031 Class. Names The four locomotives, which with their double-curved running plates were exceptionally handsome, were named as follows: * 7 Charles Saunders (first), Armstrong (sec ...

4-4-0
4-4-0 is a locomotive type with a classification that uses the Whyte notation for the classification of steam locomotives by wheel arrangement and represents the arrangement: four leading wheels on two axles (usually in a leading bogie), four powered and coupled driving wheels on two axles, and a lack of trailing wheels. Due to the large number of the type that were produced and used in the United States, the 4-4-0 is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced.White, John H., Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York: Dover Publications, pp. 46-. Almost every major railroad that operated in North America in the first half of the 19th century owned and operated locomotives of this type. The first use of the name ''American'' to describe locomotives of this wheel arrangement was made by ''Railroad Gazette'' in April 1872. Prior to ...

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 ...

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 ...

GWR Dean Experimental Locomotives
During the 1880s and 1890s, William Dean constructed a series of experimental locomotives to test various new ideas in locomotive construction for the Great Western Railway. Locomotives No. 1 This locomotive appeared in 1880 as a 4-4-0T, but was rebuilt in 1882 as a 2-4-0T. It was withdrawn in 1924. No. 7 Number 7 was built in 1886 at Swindon as a tandem compound 2-4-0 with coupled wheels and outside frames. The diameter low pressure cylinders were in front of the high pressure cylinders, the pistons being carried on the same piston rod. Valves for the low pressure cylinders were below, and those for the high pressure cylinders above the cylinders. One set of valve gear drove each pair of valve spindles. This setup proved difficult to access for maintenance, and the locomotive was relegated to minor routes. It was broken up in 1890. The wheel centres were used in building No. 7 of the Armstrong class. No. 8 Number 8 was built in 1886 as a broad gauge convertible 2-4-0 tand ...

GWR 3001 Class
The 3001 Class as constructed by William Dean at the Swindon Works of the Great Western Railway in 1891-2 was the culmination of the tradition of GWR 2-2-2 locomotives that had begun with Gooch's ''North Star'' over 50 years earlier. The 3001s, which had driving wheels, were built in two batches: Because of the restricted width available between the large driving wheels, these locomotives were fitted with narrow diameter boilers. In order to increase the heating surface the boilers were made longer than previous types, and were fitted with raised fireboxes. Despite the fact that the broad gauge was in its very final months, new broad gauge engines were still needed to maintain services, and eight of these new engines, Nos. 3021-3028, were built (as "convertibles") with the wheels outside the frames, to run on the broad gauge. They were duly converted to "narrow" (standard) gauge in summer 1892. These engines were too heavy at the front end, and after a derailment in 1893 ...

GWR 3031 Class
The Dean Single, 3031 Class, or Achilles Class was a type of steam locomotive built by the British Great Western Railway between 1891 and 1899. They were designed by William Dean for passenger work. The first 30 members of the class were built as 2-2-2s of the 3001 Class. The first eight members of the class (numbers 3021-3028, built April–August 1891) were built as convertible broad gauge 2-2-2 locomotives, being converted to standard gauge in mid-1892, at the end of broad gauge running on the Great Western Railway. A further 22 were built in late 1891 and early 1892, this time as standard gauge engines. Although the 3001 class were fitted with larger boilers than earlier GWR 2-2-2 classes, the diameter of the boiler was constrained by its position between the driving wheels. Thus boiler capacity could only be increased by making the boiler longer, not wider, bringing the smokebox and cylinders in front of the leading axle. The extra weight of the larger boilers was bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GWR 4100 Class
The GWR 4100 Class was a class of steam locomotives in the Great Western Railway (GWR) of the United Kingdom. The Badminton class express passenger 4-4-0 steam locomotives were introduced in 1897 as a development from the earlier GWR 3252 Class, Duke class. The name Badminton was chosen after the Duke of Beaufort's Badminton House, Badminton estate, through which the GWR was building South Wales Main Line, a new line to South Wales at the time. Further modifications to the design resulted in the Atbara Class entering service in 1900, the names for these locomotives generally being taken from contemporary military engagements or senior army commanders. Later engines were named after cities of the British Empire. The final batch of locomotives were named after varieties of garden plant and in consequence were known as the Flower Class. These three types were later standardised and treated as a single class, so are listed together here. Four other prototype 4-4-0s, originally bu ...

Experimental Locomotives
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
