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 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 GWR 1400 Class is a class of steam locomotive designed by the Great Western Railway for branch line passenger work. It was originally classified as the 4800 Class when introduced in 1932, and renumbered in 1946.
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 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.
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.
Charles Benjamin Collett was Chief Mechanical Engineer of the Great Western Railway from 1922 to 1941. He designed the GWR's 4-6-0 Castle and King Class express passenger locomotives.
The GWR 0-6-0PT, is a type of steam locomotive built by the British Great Western Railway with the water tanks carried on both sides of the boiler, in the manner of panniers. They were used for local, suburban and branch line passenger and goods traffic, for shunting duties, and as banker engines on inclines. The early examples, such as the 1901 and 2021 classes, were rebuilt from saddle or side tanks when the locos received a Belpaire firebox – this type of firebox has a square top and is incompatible with a curved saddle tank. This process mostly took place during the tenure at Swindon Works of George Jackson Churchward. Only a very small number of saddle tank locomotives escaped rebuilding as panniers, notably the 1361 Class built new under Churchward in 1910, by which date a few of the 1813 Class had already been rebuilt as pannier tanks.
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 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.
From 1920, the cab side of Great Western Railway (GWR) steam locomotives bore a letter on a coloured disc, which enabled staff to quickly assess the capabilities of locomotives without the need to check tables of data. The letter showed the power classification, and the coloured disc showed the weight restriction. This system continued after the GWR became the Western Region of British Railways.
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.
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 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.
