The Great Western Railway (GWR) 4400 Class was a class of 2-6-2T side tank steam locomotive.
They were introduced in 1904 for work on small branch lines. The 4500 class was a later development with larger driving wheels. The 4400s were particularly used in hilly districts, notably the Princetown and Much Wenlock Branches. [2] All were withdrawn and scrapped between 1949 and 1955. [2]
The 4400, 4500 and 4575 classes, which all had 24 in (610 mm) stroke cylinders, the Standard 5 boiler and driving wheels under 5 ft (1.524 m), were collectively known as "Small Prairies", as opposed to the 5100, 3150, 5101, 6100, 3100 and 8100 classes, with 30 in (762 mm) stroke cylinders, Standard 2 or 4 boilers and driving wheels over 5 ft (1.524 m), known as "Large Prairies".
George Jackson Churchward was an English railway engineer, and was chief mechanical engineer of the Great Western Railway (GWR) in the United Kingdom from 1902 to 1922.
The first Locomotives of the Great Western Railway (GWR) were specified by Isambard Kingdom Brunel but Daniel Gooch was soon appointed as the railway's Locomotive Superintendent. He designed several different 7 ft 1⁄4 in broad gauge types for the growing railway, such as the Firefly and later Iron Duke Class 2-2-2s. In 1864 Gooch was succeeded by Joseph Armstrong who brought his standard gauge experience to the workshops at Swindon. To replace some of the earlier locomotives, he put broad gauge wheels on his standard gauge locomotives and from this time on all locomotives were given numbers, including the broad gauge ones that had previously carried just names.
The GWR 4100 Class was a class of steam locomotives in the Great Western Railway (GWR) of the United Kingdom.
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 successful class which established the design principles for GWR 2-cylinder classes over the next fifty years.
The Great Western Railway (GWR) 4575 Class is a class of 2-6-2T British steam locomotives.
The Great Western Railway (GWR) 4500 Class or Small Prairie is a class of 2-6-2T steam locomotives.
The GWR 6100 Class is a class of 2-6-2T side tank steam locomotives.
Charles Benjamin Collett was Chief Mechanical Engineer of the Great Western Railway from 1922 to 1941. He designed the GWR's 4-6-0 Castle and King Class express passenger locomotives.
The Great Western Railway (GWR) 3100 Class was a class of 2-6-2T side tank steam locomotive.
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 called "Night Owls" because they were primarily designed to haul goods during the night and that they could be seen simmering in the daylight, awaiting their nocturnal duties.
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 19 locomotives ordered by Isambard Kingdom Brunel for the Great Western Railway included six 2-2-2 Mather, Dixon locomotives. They were built by Mather, Dixon and Company, but were unsuccessful, and were rapidly replaced by the Star Class locomotives ordered by Daniel Gooch, once he had been appointed as the Locomotive Engineer.
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.
The 517 Class were small 0-4-2T tank engines designed by George Armstrong for local passenger work on the Great Western Railway. They were built at Wolverhampton Works and were outshopped between 1868 and 1885. They were built in thirteen lots commencing with 517–528 and ending with 1477–1488 in 1884–1885.
The Rhymney Railway P class was a class of 0-6-2T steam locomotive introduced into traffic in 1909 designed by the Rhymney Railway's engineer C. T. Hurry Riches. These were substantial sized tank locomotives, weighed 60 long tons and were 35 feet 0 inches (10.67 m) in length.
No.6880 Betton Grange is a steam locomotive which is under construction as a "new-build" project, originally based on the Llangollen Railway in Denbighshire, Wales, then subsequently at Tyseley Locomotive Works. Described as "building the 81st Grange", the project started in 1998, and the locomotive was earlier expected to be operational by 2013, but subsequently by Autumn 2021. All of the original GWR 6800 Class Grange locomotives were withdrawn for scrap by the end of 1965; this project is a creation, from an assemblage of original GWR and newly manufactured components, of a member of this class.
The Great Western Railway (GWR) GWR 5100 Class was a class of 2-6-2T side tank steam locomotives. It was the first of a series of broadly similar classes used principally for suburban passenger services.
The GWR 455 Class, also called the "Metropolitan" or "Metro" Tanks, was a series of 140 2-4-0T locomotives built for the Great Western Railway, originally for their London suburban services, including running on the underground section of the Metropolitan Railway, the source of their nickname. Later on the class was seen on many other parts of the GWR system. Sixty "Metro" Tanks were built, from 1868 onwards, during the lifetime of their designer, Joseph Armstrong. His successor William Dean regarded the class so highly that he would add a further 80, the final 20 examples appearing as late as 1899. The "Metros" were all built at Swindon Works, in nine lots of ten or 20 engines each.
