The Great Western Railway (GWR) 4575 Class is a class of 2-6-2T British steam locomotives.
They were designed as small mixed traffic branch locomotives, mainly used on branch lines. They were a development of Churchward's 4500 Class with larger side tanks and increased water capacity. [2] 100 were built numbered 4575–4599 and 5500–5574. 15 (Nos. 4578/81/89, 5511/24/29/34/35/45/55/59/60/68/72/74) were fitted with auto apparatus in 1953 to enable them to run push-pull trains on South Wales lines with auto trailers. [2]
They often are referred to as Small Prairie Class tank locomotives.

11 members of the class have been preserved:
| Number and name | Home | Status | Image |
|---|---|---|---|
| 4588 | Peak Rail | Has run in preservation, but currently out of service requiring overhaul. It was sold from the Dartmouth Steam Railway in 2015 and is now owned by Mike Thompson and based at Peak Rail. [4] |  |
| 5521/L.150 | Epping Ongar Railway [5] | Built in 1927, withdrawn by BR and sent to Woodham Brothers scrapyard, having run just over 1,000,000 miles (1,600,000 km). Saved with classmates 4561 and 5542 by the West Somerset Railway Association, but was sold with 5542 to repay purchase debts and to fund restoration of 4561. Bought by Richard and William Parker in 1980, it was restored at the Flour Mill, Forest of Dean from 2004 to 2007. It was featured in the 2007 Wolsztyn Parade, [6] then travelled to Budapest, Hungary where it worked intermittently with MAV Nosztalgia, including piloting the Orient Express . It returned to Poland in 2008, operating suburban services from Wroclaw to Jelcz Laskowice. After a third appearance at the 2009 Wolsztyn Parade, it was returned to England. In May 2013, it was painted in London Transport livery and numbered L.150 to commemorate the 150th anniversary of the Metropolitan line. Returned to traffic in 2021 following overhaul. [7] |  |
| 5526 | South Devon Railway | On loan to the Gwili Railway. Boiler ticket expires in 2027. |  |
| 5532 | Llangollen Railway | Under restoration. [8] | |
| 5538 | The Flour Mill, Forest of Dean, Gloucestershire | Under restoration. Previously displayed in Barry Island. [9] |  |
| 5539 | Barry Tourist Railway | Under restoration. Previously part of the Barry Ten until 2006. [10] |  |
| 5541 | Dean Forest Railway | Currently operational. Boiler ticket expires in 2024. [11] |  |
| 5542 | South Devon Railway | Currently under overhaul at the South Devon Railway. This locomotive has visited several preserved railways throughout her preservation career. [12] |  |
| 5552 | Bodmin and Wenford Railway | Returned to service in 2023 after overhaul, having previously run from 2003 to 2013. [13] |  |
| 5553 | Peak Rail | Owned by Pete Waterman. Last steam engine to leave Woodham Brothers scrapyard in Barry, Vale of Glamorgan, South Wales, in January 1990. First resteamed in 2002, running until 2012, mostly at the West Somerset Railway. Moved in 2015 from Crewe Heritage Centre for overhaul, which was completed in 2021 at Peak Rail. Currently operational, boiler ticket expires 2031. |  |
| 5572 | Didcot Railway Centre | On static display awaiting overhaul. [14] |  |
Two members of the class have also briefly been out on the mainline: 5521 and 5572. 5521 was shipped to Poland to take part in the Wolsztyn Parade, as well as briefly piloting the Orient Express. 5572 made an appearance at an open day in Reading as part of the GWR150 celebrations in 1985, arriving under its own power. When returning to Didcot again under its own power the engine also hauled the replica broad gauge locomotive "Iron Duke" alongside the preserved GWR Railcar W22W.
Lima made a model of the 4575 class, number 4589, in GWR green, also a British Railways black-liveried version, running number 5574. Bachmann Branchline have for many years made various versions of the 4575 Class.
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 BR Standard Class 3 2-6-2T was a class of steam locomotive designed by Robert Riddles for British Railways. It was essentially a hybrid design, the chassis being closely based on and sharing a number of parts with the LMS Ivatt Class 4, and having a boiler derived from a GWR No.2 boiler as fitted to the GWR Large Prairie 2-6-2T and 5600 Class 0-6-2T tank engines.
The London, Midland and Scottish Railway (LMS) Ivatt Class 2 2-6-0 is a class of steam locomotive designed for light mixed traffic.
The Great Western Railway (GWR) 4200 Class is a class of 2-8-0T steam locomotives.
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) 2251 Class or Collett Goods Class was a class of 0-6-0 steam tender locomotives designed for medium-powered freight. They were introduced in 1930 as a replacement for the earlier Dean Goods 0-6-0s and were built up to 1948.
The Great Western Railway (GWR) 7200 Class is a class of 2-8-2T steam locomotive. They were the only 2-8-2Ts built and used by a British railway, and the largest tank engines to run on the Great Western Railway.
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) 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 GWR 6100 Class is a class of 2-6-2T side tank 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 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 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 4600 Class was a 4-4-2T steam locomotive built by the Great Western Railway in 1913. It was one of the GWR standard classes with two outside cylinders.
