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 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 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) 2221 Class or County Tank was a class of 4-4-2T steam locomotive, effectively a tank engine version of the 3800 "County" Class 4-4-0 tender locomotives. The two classes had different boilers, standard no 4 for the tender locomotive, and the smaller standard no 2 for the tank. 2230 was fitted with the larger boiler when new, but this was unsuccessful and was quickly altered.
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 Great Western Railway (GWR) 2301 Class or Dean Goods Class is a class of British 0-6-0 steam locomotives.
The Great Western Railway (GWR) 3150 Class was a class of 2-6-2T side tank steam locomotive.
The Great Western Railway (GWR) 4400 Class was a class of 2-6-2T side tank steam locomotive.
The Great Western Railway (GWR) 5800 Class was a class of twenty 0-4-2T steam tank locomotives. They were built by the GWRs Swindon Works in 1933 and were used for light branch line work. They were similar to the GWR 1400 Class, but lacked the equipment for working autotrains. The last survivor of the class, number 5815, was with withdrawn in 1961. No members of the class were preserved.
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 GWR was the longest-lived of the pre-nationalisation railway companies in Britain, surviving the 'Grouping' of the railways in 1923 almost unchanged. As a result, the history of its numbering and classification of locomotives is relatively complicated. This page explains the principal systems that were used.
The GWR 645 Class was a class of 0-6-0ST designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six were constructed between 1872-3, of which three were built for the South Wales Mineral Railway (SWMR), two for the Carmarthen and Cardigan Railway (C&CR) and the remainder for the GWR. In essence, they were saddle tank versions of his GWR 633 Class of 1871. From 1878, a further 72 of the class, partially enlarged, were added in the 1501 numbering sequence. Unlike the originals, the "1501"s had full-length saddle tanks from the start.
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 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.
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 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.
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 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.
