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 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 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 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 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.
Joseph Armstrong was an English locomotive engineer and the second locomotive superintendent of the Great Western Railway. His younger brother George and one of his sons also became outstanding engineers in the employment of the GWR.
The GWR 1901 Class was a class of 120 small 0-6-0ST steam locomotives. Numbered 1901–2020, they were designed by George Armstrong and built at the Wolverhampton railway works, England, of the Great Western Railway between 1881 and 1895. They had wheels of 4 ft 0 in (1.219 m) diameter and a coupled wheelbase of 13 ft 8 in (4.17 m).
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 Daniel Gooch standard gauge locomotives comprise several classes of locomotives designed by Daniel Gooch, Superintendent of Locomotive Engines for the Great Western Railway (GWR) from 1837 to 1864.
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 322 Class tank engines comprised six Great Western Railway outside-framed 0-6-0 steam locomotives, originally built by Beyer, Peacock, and Company as 322 class tender engines and subsequently rebuilt in 1878–85 as saddle tank locomotives by George Armstrong at Wolverhampton Works.
Class 655 of the Great Western Railway was a class of 52 0-6-0ST locomotives designed by George Armstrong and built at the GWR's Wolverhampton Works.
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 1661 Class was William Dean's second design of tank locomotive for England's Great Western Railway. Like the 1813 Class which preceded them, there were 40 1661s, turned out of Swindon Works in two batches.
The GWR 1854 Class was a class of 0-6-0T steam locomotives designed by William Dean and constructed at the Swindon Works of the Great Western Railway. The class used similar inside frames and chassis dimensions to the 1813 Class of 1882-4. In this they differed from the intervening 1661 Class, which had reverted to the double frames of the Armstrong era. Thus the 1854 Class belongs to the "mainstream" of GWR 0-6-0T classes that leads towards the larger GWR pannier tanks of the 20th century.
The 2602 Class was a series of steam locomotives designed by William Dean and built at the Swindon Works of the Great Western Railway.
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.
The 3232 Class, 20 2-4-0 locomotives designed by William Dean and built at Swindon Works for the Great Western Railway in 1892–93, were the GWR's last completely new 2-4-0 design. Their number series was 3232–3251.
