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 GWR 5700 Class is a class of 0-6-0 pannier tank steam locomotive built by the Great Western Railway (GWR) and British Railways (BR) between 1929 and 1950. With 863 built, they were the most prolific class of the GWR, and one of the most numerous classes of British steam locomotive.
The Great Western Railway (GWR) 6959 or Modified Hall Class is a class of 4-6-0 steam locomotive. They were a development by Frederick Hawksworth of Charles Collett's earlier Hall Class named after English and Welsh country houses.
The GWR 1400 Class is a class of steam locomotive designed by the Great Western Railway for branch line passenger work. It was originally classified as the 4800 Class when introduced in 1932, and renumbered in 1946.
The 1361 Class were small 0-6-0ST steam locomotives built by the Great Western Railway at their Swindon Works, England, mainly for shunting in docks and other sidings where track curvature was too tight for large locomotives.
The GWR 5600 Class is a class of 0-6-2T steam locomotive built between 1924 and 1928. They were designed by Charles Collett for the Great Western Railway (GWR), and were introduced into traffic in 1924. After the 1923 grouping, Swindon inherited a large and variable collection of locomotives from historic Welsh railway companies, which did not fit into their standardisation programme. GWR boiler inspectors arrived en masse and either condemned the original locomotives or had them rebuilt. The systematic destruction of many examples of locomotives, most still in serviceable condition, followed, but various were worked alongside 5600 Class.
The Great Western Railway (GWR) 5400 Class was a class of 0-6-0 pannier tank steam locomotive. They were similar in appearance to many other GWR tank engines but smaller than the ubiquitous GWR 5700 Class.
The Great Western Railway (GWR) 6400 Class is a class of 0-6-0 pannier tank steam locomotive introduced by Charles Collett in 1932. All 40 examples were 'auto-fitted' – equipped with the remote-control equipment needed for working autotrains.
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.
Frederick William Hawksworth, was the last Chief Mechanical Engineer of the Great Western Railway (GWR).
George Armstrong 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.
The GWR 2021 Class was a class of 140 0-6-0ST steam locomotives. They were built at the Wolverhampton railway works of the Great Western Railway between 1897 and 1905. 1897 was the very year of George Armstrong's retirement, so it is uncertain if the design should be attributed to him or to his superior at Swindon, William Dean.
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 GWR 2721 Class was a class of 0-6-0ST steam locomotives. They were designed by William Dean and built at the Swindon Works of the Great Western Railway between 1897 and 1901.
The GWR Class 850 was an extensive class of small 0-6-0ST locomotives designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway between 1874 and 1895. Aptly described as the GWR equivalent of the LB&SCR "Terrier" Class of William Stroudley, their wide availability and lively performance gave them long lives, and eventually they were replaced from 1949 by what were in essence very similar locomotives, the short-lived 1600 Class of Frederick Hawksworth, which in the headlong abandonment of steam outlived them by a mere seven years or so.
The 1016 Class consisted of sixty double framed 0-6-0ST locomotives designed by George Armstrong and built at the Wolverhampton Works of the Great Western Railway between 1867 and 1871. Like the earlier 302 Class of Joseph Armstrong, the 1016s had 4 ft 6 in (1.372 m) wheels and a 15 ft 6 in (4.72 m) wheelbase, dimensions that would remain traditional for the larger GWR pannier tanks right through to Charles Collett's 5700 Class, and with little change to Frederick Hawksworth's 9400 Class of 1947.
The Great Western Railway's 1813 Class was a series of 40 0-6-0T built at Swindon Works in two lots of 20 engines each. No. 1813 was sold to the Pembroke & Tenby Railway in May 1883 becoming No.7 Holmwood, retaining this name after being absorbed by the GWR. Nearly all of these engines spent their lives on the GWR's Southern Division.
The GWR 101 Class consisted of a single experimental 0-4-0T side-tank steam locomotive. It was built at GWR Swindon Works under the direction of George Jackson Churchward in June 1902.
The Great Western Railway (GWR) experimented with oil burning steam locomotives at two points in its history. A single experimental tank engine was constructed to burn oil in 1902, and 37 engines of four different classes were converted to burn oil between 1946 and 1950. Neither experiment resulted in the long-term use of oil as fuel for steam locomotives. A single pannier tank locomotive was also converted under British Rail in 1958.
