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.
Beyer, Peacock and Company was an English general engineering company and railway locomotive manufacturer with a factory in Openshaw, Manchester. Charles Beyer, Richard Peacock and Henry Robertson founded the company in 1854. The company closed its railway operations in the early 1960s. It retained its stock market listing until 1976, when it was bought and absorbed by National Chemical Industries of Saudi Arabia.
Under the Whyte notation for the classification of steam locomotives, 0-4-2 represents the wheel arrangement with no leading wheels, four powered and coupled driving wheels on two axles and two trailing wheels on one axle. While the first locomotives of this wheel arrangement were tender engines, the configuration was later often used for tank engines, which is noted by adding letter suffixes to the configuration, such as 0-4-2T for a conventional side-tank locomotive, 0-4-2ST for a saddle-tank locomotive, 0-4-2WT for a well-tank locomotive and 0-4-2RT for a rack-equipped tank locomotive.
The Great Western Railway (GWR) 4200 Class is a class of 2-8-0T steam locomotives.
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.
Indian Railways operates India's railway system and comes under the purview of the Ministry of Railways of Government of India. As of 2023, it maintains over 108,706 km (67,547 mi) of tracks and operates over 13,000 trains daily with a fleet of 14,800 locomotives. The railways primarily operates a fleet of electric and diesel locomotives along with a few compressed natural gas (CNG) locomotives. Steam locomotives are operated on mountain railways and on heritage trains.
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 Great Northern Railway Class J23 was a class of 0-6-0T steam locomotive. They had long side tanks that came to the front of the smokebox, which sloped forwards to improve visibility and had a recess cut in to aid maintenance. Forty were built by the Great Northern Railway (GNR) between 1913 and 1922, with a further 62 being added by the London and North Eastern Railway (LNER) between 1924 and 1939. They were given the nickname "Submarines" due to their long tanks.
Under the Whyte notation for the classification of steam locomotives, 0-8-4 represents the wheel arrangement of no leading wheels, eight powered and coupled driving wheels on four axles, and four trailing wheels on two axles.
The Rhymney Railway A class were 0-6-2T tank locomotives introduced into traffic in 1910 and designed by the railway's engineer Hurry Riches. These were substantial sized tank engines, and weighed 64 long tons and were 35 ft 9 in (10.90 m) in length.
Brecon and Merthyr 0-6-2T locomotives were steam tank locomotives of the Brecon and Merthyr Railway including classes 36 and 45.
The Phoenix Foundry was a company that built steam locomotives and other industrial machinery in the city of Ballarat, Victoria, Australia. Over 30 years they built 352 locomotives for the Victorian Railways, of 38 different designs.
The Victorian Railways B class was a class of 2-4-0 passenger locomotives operated by the Victorian Railways (VR) between 1862 and 1917, built by various builders. The B class locomotives are regarded as the first mainline VR motive power, and were highly successful in passenger operations.
The Z18 class was a class consisting of six 0-6-0T steam tank locomotives built by Vulcan Foundry for the New South Wales Government Railways of Australia.
The Victorian Railways Z class were three locomotives built in 1893 in Victoria, Australia
The E class was a class of suburban tank steam locomotive that ran on Australia's Victorian Railways (VR).
The Victorian Railways F class was originally a class of 2-4-0 light line passenger locomotives operated by the Victorian Railways between 1874 and 1929.
The South African Railways Class C1 4-6-2T of 1901 was a steam locomotive from the pre-Union era in the Natal Colony.
The Lancashire and Yorkshire Railway (L&YR) Barton Wright 0-6-2T were tank engines introduced by Barton Wright between 1877 and 1883. This was the first use of the 0-6-2T type in Britain.
