The Great Western Railway's 1813 Class was a series of 40 0-6-0 T 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.
| Year | Quantity | Lot No. | Works Nos. | Locomotive numbers | Notes |
|---|---|---|---|---|---|
| 1882–83 | 20 | 59 | 906–925 | 1813–1832 | |
| 1883–84 | 20 | 60 | 926–945 | 1834–1853 |
This was the first 0-6-0 T design of William Dean and in its concept and dimensions may be regarded as the precursor of all the larger GWR pannier tanks of the 20th century, such as the 5700 and 9400 classes:
From 1894 some of the 1813s were rebuilt with saddle tanks, and between 1903 and 1906, six were rebuilt with either short or full-length pannier tanks, resulting in a very early example of this type of engine. The rest were so converted between 1911 and 1925, as had become standard practice on the Great Western. The class also carried an unusually wide variety of different boilers.
No. 1835 alone passed into British Railways stock, to be withdrawn in January 1949. [2]
The Great Western Railway (GWR) 4200 Class is a class of 2-8-0T steam locomotives.
The Great Western Railway (GWR) 5205 Class is a class of 2-8-0T steam locomotives.
The Great Western Railway (GWR) 1600 Class is a class of 0-6-0 pannier tank steam locomotive designed for light branch lines, short-distance freight transfers and shunting duties.
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) 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.
The Great Western Railway (GWR) 3150 Class was a class of 2-6-2T side tank steam locomotive.
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 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 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 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 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 633 Class were 0-6-0Ts designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway between November 1871 and April 1872. These were always Southern Division locomotives, but over the years some were fitted to work the Metropolitan lines and played a large role in the transportation of goods from Acton to Smithfield. Unusually, they had side tanks, and inside frames, with wheels of 4 ft 6+1⁄2 in (1,384 mm) in diameter and a wheelbase of 15 ft 6 in (4.72 m). Their weight was 34 long tons 12 cwt. There were twelve locomotives, numbered 633–644.
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 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 GWR 3511 class were standard gauge 2-4-0T locomotives designed by William Dean for the Great Western Railway and built in 1885.
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.
