The Great Western Railway 4000 or Star were a class of 4-cylinder 4-6-0 passenger steam locomotives designed by George Jackson Churchward for the Great Western Railway (GWR) in 1906 and introduced from early 1907. The prototype was built as a 4-4-2 Atlantic. They proved to be a successful design which handled the heaviest long-distance express trains, reaching top speeds of 90 mph (145 km/h), and established the design principles for GWR 4-cylinder classes over the next twenty-five years.
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 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 2900 Class or Saint Class, which was built by the Great Western Railway's Swindon Works, incorporated several series of 2-cylinder passenger steam locomotives designed by George Jackson Churchward and built between 1902 and 1913 with differences in the dimensions. The majority of these were built as 4-6-0 locomotives; but thirteen examples were built as 4-4-2. They proved to be a highly successful class which established the design principles for GWR 2-cylinder classes over the next fifty years, and influenced similar classes on other British railways.
The Great Western Railway (GWR) Star Class of 2-2-2 broad gauge steam locomotives were used for passenger train work. Designed by Robert Stephenson, the class was introduced into service between November 1838 and November 1841, and withdrawn between April 1864 and September 1871.
The Great Western Railway (GWR) Ariadne Class and Caliph Class were broad gauge 0-6-0 steam locomotives designed for goods train work by Daniel Gooch and are often referred to as his Standard Goods locomotives.
The Great Western Railway (GWR) Bogie Class4-4-0ST were broad gauge steam locomotives for passenger train work. The first two locomotives of this class were introduced into service in August/September 1849, with the remainder following between June 1854 and March 1855. All but one were withdrawn between October 1871 and 1873, with the final locomotive being withdrawn in December 1880.
The Great Western Railway Iron Duke Class 4-2-2 was a class of 7 ft 1⁄4 in broad gauge steam locomotives for express passenger train work.
The Great Western Railway Sir Watkin Class were 0-6-0T broad gauge steam locomotives. They were designed for working goods trains through to the underground Metropolitan Railway in London. This class was introduced into service between December 1865 and the last was withdrawn at the end of the GWR broad gauge in May 1892. They were all named after directors and senior officers of the railway.
The Great Western Railway Swindon Class were broad gauge 0-6-0 locomotives built for goods train work. This class entered service between November 1865 and March 1866, and were withdrawn between June 1887 and the end of the GWR broad gauge in May 1892. The entire class was sold to the Bristol and Exeter Railway between July 1872 and September 1874 and were numbered 96-109, but returned to the GWR when that railway was absorbed. The locomotives were then renumbered 2077-2090; their names were not restored.
Joseph Armstrong was an English locomotive engineer and the second locomotive superintendent of the Great Western Railway. His younger brother George and one of his sons also became outstanding engineers in the employment of the GWR.
The South Devon Railway 2-4-0 locomotives were small 2-4-0T broad gauge locomotives operated on the South Devon Railway, mainly on its branch lines such as that to Ashburton.
The four Tornado class locomotives were 0-6-0ST broad gauge locomotives operated on the South Devon Railway and associated railways. They were designed for goods trains but were also used on passenger trains when required.
The eight Dido class locomotives were 0-6-0ST broad gauge locomotives operated on the South Devon Railway and Cornwall Railway and associated other adjacent railways. They were designed for goods trains but were also used on passenger trains when required.
The Bristol and Exeter Railway locomotives worked trains on the Bristol and Exeter Railway from 1 May 1849 until the railway was amalgamated with the Great Western Railway on 1 January 1876.
The Bristol and Exeter Railway 2-4-0 locomotives were two classes of 2-4-0 broad gauge steam locomotives.
The GWR Hercules Class were four broad gauge steam locomotives for the Great Western Railway. They were its first 0-6-0 locomotives, being built in 1842 by Nasmyth, Gaskell and Company stemming from the company's need for goods locomotives. This resulted in the last four Firefly Class locomotives being modified while still in production. From about 1865, the Hercules Class locomotives became part of the Fury Class, along with the Premier Class locomotives. They were withdrawn between 1870 and 1871.
The first 19 locomotives ordered by Isambard Kingdom Brunel for the Great Western Railway included two unusual Haigh Foundry locomotives.
Thunderer was the first of a pair of steam locomotives built for the Great Western Railway (GWR), England, by R. & W. Hawthorn & Co. whose design was very different from other locomotives. In order to meet Isambard Kingdom Brunel's strict specifications, an 0-4-0 frame carried the 'engine', while the boiler was on a separate six-wheeled frame. The driving wheels were geared 10:27 to reduce the cylinder stroke speed while allowing high track speed, in line with the specifications.
During the 1880s and 1890s, William Dean constructed a series of experimental locomotives to test various new ideas in locomotive construction for the Great Western Railway.
