The Great Western Railway 3800 Class, also known as the County Class, were a class of 4-4-0 steam locomotives for express passenger train work introduced in 1904 in a batch of ten. Two more batches followed in 1906 and 1912 with minor differences. They were designed by George Jackson Churchward, who used standard components to produce a four-coupled version of his Saint Class 4-6-0s.
The Great Western Railway 3200 Class was a design of 4-4-0 steam locomotive for passenger train work. The nickname for this class, almost universally used at the time these engines were in service was Dukedog since the locomotives were composed of former Duke Class boilers on Bulldog Class frames. As such they were one of the last standard gauge steam locomotive classes to retain outside frames.
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 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 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) 4575 Class is a class of 2-6-2T British steam locomotives.
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) 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 3501 Class were ten broad gauge 2-4-0 locomotives built by the Great Western Railway.
The GWR 388 class was a large class of 310 0-6-0 goods locomotives built by the Great Western Railway. They are sometimes referred to as the Armstrong Goods or Armstrong Standard Goods to differentiate from the Gooch Goods and Dean Goods classes, both of which were also large classes of standard goods locomotives.
The GWR 2201 Class was a class of 4 ft 8+1⁄2 instandard gauge2-4-0 steam locomotives built at Swindon Works under the aegis of William Dean for express passenger service on the Great Western Railway. Built in 1881–82, they were numbered 2201 to 2220.
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 3001 Class as constructed by William Dean at the Swindon Works of the Great Western Railway in 1891-2 was the culmination of the tradition of GWR 2-2-2 locomotives that had begun with Gooch's North Star over 50 years earlier. The 3001s, which had 7 ft 9 in (2.362 m) driving wheels, were built in two batches:
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 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.
