The 2602 Class was a series of steam locomotives designed by William Dean and built at the Swindon Works of the Great Western Railway.
They had outside frames for the six-coupled driving wheels but inside frames for the leading wheels. Initially, a distinctive visual feature was a large saddle-shaped sandbox over the first ring of the boiler. The class had two prototypes: No. 2601, which was a 4-6-0, while No. 2602 was a 2-6-0. These were built in 1899, and Nos. 2603-2610 followed later up to 1903, all 2-6-0. Though Dean was officially still in charge, Churchward's influence is evident in the rugged design. Their perhaps ironic nickname was after Paul Kruger, the Boer War leader defeated by Lord Roberts in 1900.
Perhaps Churchward saw the chance of experimenting in the name of Dean, and this somewhat experimental class was not successful; the boiler's high pressure and 3 ft 6 in (1.067 m) long combustion chamber gave trouble [1] and the long 28-inch (711 mm) stroke of the inside cylinders led to fractures of the solid crank axles. [2] The class was thus short-lived, and most were withdrawn around 1906. Several of the boilers were converted for stationary use in Swindon Works at reduced pressure and remained in service there until the 1950s.
Their numbers were adopted in 1907 by some of the last batch of the popular and reliable Aberdare Class 2-6-0s, which may also have re-used some of the "Kruger"s' parts. [3]
The Great Bear, number 111, was a locomotive of the Great Western Railway. It was the first 4-6-2 (Pacific) locomotive used on a railway in Great Britain, and the only one of its type built by the GWR.
The GWR 4100 Class was a class of steam locomotives in the Great Western Railway (GWR) of the United Kingdom.
The Bulldog and Bird classes were double-framed inside cylinder 4-4-0 steam locomotives used for passenger services on the Great Western Railway. The Bird Class were a development of the Bulldogs with strengthened outside frames, of which a total of fifteen were built. A total of 121 Bulldogs were built new, with a further twenty rebuilt from Duke Class locomotives. Thirty Bulldogs were later rebuilt as Earl Class locomotives and renumbered 3265, 3200-3228.
The Great Western Railway 3800 Class, also known as the County Class, were a class of 4-4-0 steam locomotives for express passenger train work introduced in 1904 in a batch of ten. Two more batches followed in 1906 and 1912 with minor differences. They were designed by George Jackson Churchward, who used standard components to produce a four-coupled version of his Saint Class 4-6-0s.
The Great Western Railway 2900 Class or Saint Class, which was built by the Great Western Railway's Swindon Works, incorporated several series of 2-cylinder passenger steam locomotives designed by George Jackson Churchward and built between 1902 and 1913 with differences in the dimensions. The majority of these were built as 4-6-0 locomotives; but thirteen examples were built as 4-4-2. They proved to be a highly successful class which established the design principles for GWR 2-cylinder classes over the next fifty years, and influenced similar classes on other British railways.
The Great Western Railway (GWR) 4200 Class is a class of 2-8-0T steam locomotives.
The Great Western Railway (GWR) 6800 Class or Grange Class was a mixed-traffic class of 4-6-0 steam locomotive, built to replace the GWR 4300 Class 2-6-0. There were 80 in the class, all built at the Swindon works, using some reconditioned parts from withdrawn 4300 Class locomotives.
The Great Western Railway (GWR) 4300 Class is a class of 2-6-0 (mogul) steam locomotives, designed by G.J. Churchward for mixed traffic duties. 342 were built from 1911–1932.
The Great Western Railway (GWR) 4700 Class was a class of nine 2-8-0 steam locomotives, designed by George Jackson Churchward. They were introduced in 1919 for heavy mixed-traffic work. Although primarily designed for fast freight, the class also sometimes hauled passenger trains, notably heavy holiday expresses in the summer months. They were unofficially nicknamed "Night Owls" because they were primarily designed to haul goods during the night and they could be seen simmering in the daylight, awaiting their nocturnal duties.
The Great Western Railway (GWR) 3600 Class was a class of 2-4-2T side tank steam locomotive, designed by William Dean and built at Swindon in three lots in 1900-1903:
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 3521 Class were forty tank locomotives designed by William Dean to haul passenger trains on the Great Western Railway. They were introduced as 0-4-2T locomotives in 1887, but were quickly altered to become 0-4-4Ts to improve their running. Following two serious accidents they were further altered from 1899 to run as 4-4-0 tender locomotives, in which form the last was withdrawn in 1934.
La France, number 102, was a locomotive of the Great Western Railway. It was bought by G.J. Churchward to evaluate French locomotive practice, and particularly the effect of compounding.
The Queen Class was Joseph Armstrong's last class of 2-2-2 express engine for the Great Western Railway, larger than the Sir Daniel Class of about a decade earlier. They worked express trains for almost 30 years, and were in effect the predecessors of the larger Singles of William Dean.
Between 1854 when the Shrewsbury and Chester and Shrewsbury and Birmingham Railways were absorbed by the Great Western Railway, and 1864 when he moved south to Swindon Works, Joseph Armstrong occupied the post of the GWR's Locomotive Superintendent, Northern Division, at Wolverhampton Works. For ten years the task of providing new locomotives for the GWR's newly acquired standard gauge lines fell jointly to Armstrong and to his superior Daniel Gooch, the railway's principal Locomotive Superintendent who was based at Paddington.
The 3206 or Barnum Class consisted of 20 locomotives built at Swindon Works for the Great Western Railway in 1889, and was William Dean's most successful 2-4-0 design. Numbered 3206–3225, they were the last GWR locos built at Swindon with "sandwich" frames.
GWR No. 36 was a prototype 4-6-0 steam locomotive constructed at Swindon Works for the Great Western Railway in 1896, the first 4-6-0 ever built for the GWR and one of the first in Britain. It was designed by William Dean and le Fleming comments that "the design is unusual and entirely Dean of the later period, including the only large boiler ever built entirely to his ideas."
President, number 103, and Alliance, number 104 were locomotives of the Great Western Railway. George Jackson Churchward, Chief Mechanical Engineer of the Great Western Railway, was given authority to purchase three French de Glehn-du Bousquet four-cylinder compound locomotives, in order to evaluate the benefits of compounding. The first locomotive, no.102 La France, was delivered in 1903. Two further locomotives, nos. 103 and 104, were purchased in 1905. These were similar to the Paris-Orleans Railway's 3001 class, and slightly larger than 102. As with no. 102, these were built by Société Alsacienne de Constructions Mécaniques. They had two low-pressure cylinders fitted between the frames, and two high-pressure cylinders outside. The low-pressure cylinders drove the front driving wheels while the high-pressure cylinders drove the rear driving wheels. An external steam pipe was mounted just in front of the dome, looking rather similar in appearance to a top feed. In 1907 No. 104 was fitted with an unsuperheated Swindon No. 1 boiler, President herself being similarly reboilered in February 1910 and receiving a superheated boiler in January 1914. In 1926, the three locomotives were based at Oxford shed. In practice, they did not provide any significant improvement in either performance or economy compared to No 171 Albion, Churchward's prototype 4-6-0, which was converted to a 4-4-2 specifically for comparison with the French locomotives.
The 4600 Class was a 4-4-2T steam locomotive built by the Great Western Railway in 1913. It was one of the GWR standard classes with two outside cylinders.
The Great Western Railway (GWR) 3901 Class is a class of 2-6-2T steam locomotives rebuilt from class 2301 'Dean Goods' 0-6-0 tender locomotives.
