The GWR 0-4-0ST steam locomotives were acquired by the Great Western Railway at the 1923 grouping. They came from small railways (mostly in South Wales) and from contractors. Some of them survived into British Railways ownership in 1948 and a few are preserved.

The London, Midland and Scottish Railway (LMS) Princess Royal Class is a class of express passenger 4-6-2 steam locomotive designed by William Stanier. Twelve examples were built at Crewe Works, between 1933 and 1935, for use on the West Coast Main Line. Two are preserved.
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 Great Western Railway 4900 Class or Hall Class is a class of 4-6-0 mixed-traffic steam locomotives designed by Charles Collett for the Great Western Railway. A total of 259 were built at Swindon Works, numbered 4900–4999, 5900–5999 and 6900–6958. The LMS Stanier Class 5 4-6-0 and LNER Thompson Class B1 both drew heavily on design features of the Hall Class. After nationalisation in 1948, British Railways gave them the power classification 5MT.
The Caledonian Railway 60 Class were 4-6-0 passenger engines designed by William Pickersgill and introduced in 1916. Six were built by the Caledonian Railway at its own St. Rollox works in 1916–17, and all of them passed into LMS ownership in 1923. A further twenty locomotives of a slightly modified design were built by the LMS under the auspices of George Hughes in the period of 1925–1926.
The GWR 5700 Class is a class of 0-6-0PT 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) 2884 Class is a class of 2-8-0 steam locomotive. They were Collett's development of Churchward's earlier 2800 Class and are sometimes regarded as belonging to that class.
The Great Western Railway (GWR) 2800 Class is a class of Churchward-designed 2-8-0 steam locomotive.
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) 4575 Class is a class of 2-6-2T British steam locomotives.
The Caledonian Railway 72 Class was a class of 4-4-0 steam locomotives introduced by William Pickersgill for the Caledonian Railway (CR) in 1920. Thirty-two locomotives were built and all survived to be taken over by the London, Midland and Scottish Railway (LMS) in 1923 and by British Railways (BR) in 1948. The earlier 113 Class, of which 16 were produced, were similar but slightly smaller. These were the Caledonian's last express passenger locomotives, and technically, the last of the Dunalastair series, and were unofficially dubbed, Dunalastair V.
The steam rail motors (SRM) were self-propelled carriages operated by the Great Western Railway in England and Wales from 1903 to 1935. They incorporated a steam locomotive within the body of the carriage.
The Rhymney R class was a class of 0-6-2T steam locomotive introduced into traffic in 1907 designed by the railway's engineer Hurry Riches. These were substantial sized tank locomotives, and weighed 67 long tons and were 37 feet (11.28 m) in length.
GWR No. 1334, and sister locomotives 1335 and 1336, were 2-4-0 steam locomotives which the Great Western Railway inherited from the Midland and South Western Junction Railway.
The GCR Classes 9D, 9H and 9M were a class of 124 0-6-0 Steam locomotives designed by Harry Pollitt for freight work on the Manchester, Sheffield and Lincolnshire Railway (MS&LR) later renamed Great Central Railway (GCR).
The L&YR Class 31 was a class of 0-8-0 steam locomotives of the Lancashire and Yorkshire Railway. The class was designed by George Hughes and introduced in 1912. The class comprised 115 new locomotives and 40 rebuilt from other classes.
The SECR F1 class was a series of 4-4-0 steam locomotives operated by the South Eastern and Chatham Railway. These locomotives were rebuilt from older Stirling F class locomotives by Harry Wainwright between 1903 and 1919.
The LCDR T class was a class of 0-6-0T steam locomotives of the London, Chatham and Dover Railway. The class was designed by William Kirtley and introduced in 1879.
The Caledonian Railway 294 and 711 Classes were 0-6-0 steam locomotives designed by Dugald Drummond for the Caledonian Railway (CR) and introduced in 1883. After Drummond's retirement, construction of the class continued under Smellie, Lambie and McIntosh.
The GWR Rheidol Tanks are a fleet of 2-6-2T steam locomotives of the Great Western Railway design built between 1923 and 1924. They were designed by the railway's Chief Mechanical Engineer, Charles Collett, for working services on the Vale of Rheidol Railway between Aberystwyth and Devil's Bridge (Pontarfynach).
