A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels.
A Fairlie locomotive is a type of articulated steam locomotive that has the driving wheels on bogies. The locomotive may be double-ended or single ended. Fairlies are most famously associated with the Ffestiniog Railway in North Wales.
The steam locomotives of British Railways were used by British Railways over the period 1948–1968. The vast majority of these were inherited from its four constituent companies, the "Big Four".
The BR Standard Class 8 was a class of a single 4-6-2 Pacific steam locomotive designed by Robert Riddles for use by British Railways. Only the prototype was constructed, named Duke of Gloucester. Constructed at Crewe Works in 1954, the Duke, as it is popularly known, was a replacement for the destroyed LMS Princess Royal Class locomotive number 46202 Princess Anne, which was involved in the Harrow and Wealdstone rail crash of 1952.
The British Railways Standard Class 4 4-6-0 is a class of steam locomotives, 80 of which were built during the 1950s. Six have been preserved.
The BR Standard Class 6, otherwise known as the Clan Class, was a class of 4-6-2 Pacific tender steam locomotive designed by Robert Riddles for use by British Railways. Ten locomotives were constructed between 1951 and 1952, with a further 15 planned for construction. However, due to acute steel shortages in Britain, the order was continually postponed until it was finally cancelled on the publication of the 1955 Modernisation Plan for the re-equipment of British Railways. All of the original locomotives were scrapped, but a new one is being built.
The BR Standard Class 7, otherwise known as the Britannia Class, is a class of 4-6-2 Pacific steam locomotive designed under Robert Riddles for use by British Railways for mixed-traffic duties. 55 were constructed between 1951 and 1954. The design employed results from the 1948 locomotive exchanges undertaken in advance of further locomotive classes being constructed. Three batches were constructed at Crewe Works, before the publication of the 1955 Modernisation Plan.
The BR Standard steam locomotives were an effort to standardize locomotives from the motley collection of older pre-grouping locos. Construction started in 1951. Due to the controversial British Railways' modernisation plan of 1955, where steam traction was abandoned in favour of diesel and electric traction, many of the locomotives' working lives were very short: between 7 and 17 years. Many have been preserved, mainly due to being sent to Barry Scrapyard.
The BR Standard Class 3 2-6-2T was a class of steam locomotive designed by Robert Riddles for British Railways. It was essentially a hybrid design, the chassis being closely based on and sharing a number of parts with the LMS Ivatt Class 4, and having a boiler derived from a GWR No.2 boiler as fitted to the GWR Large Prairie 2-6-2T and 5600 Class 0-6-2T tank engines.
The LSWR N15 class was a British 2–cylinder 4-6-0 express passenger steam locomotive designed by Robert Urie. The class has a complex build history spanning three sub-classes and ten years of construction from 1918 to 1927. The first batch of the class was constructed for the London and South Western Railway (LSWR), where they hauled heavy express passenger trains to the south coast ports and further west to Exeter. After the Lord Nelsons, they were the second biggest 4-6-0 passenger locomotives on the Southern Railway. They could reach speeds of up to 90 mph (145 km/h).
The Great Western Railway (GWR) 6959 or Modified Hall Class is a class of 4-6-0 steam locomotive. They were a development by Frederick Hawksworth of Charles Collett's earlier Hall Class named after English and Welsh country houses.
British Railways Standard Class 7 'Britannia Class' No. 70000 Britannia is a preserved steam locomotive, owned by the Royal Scot Locomotive and General Trust.
The LSWR S15 class is a British 2-cylinder 4-6-0 freight steam locomotive designed by Robert W. Urie, based on his H15 class and N15 class locomotives. The class had a complex build history, spanning several years of construction from 1920 to 1936. The first examples were constructed for the London and South Western Railway (LSWR), where they hauled freight trains to the south coast ports and further west to Exeter, as well as occasional passenger work in conjunction with their larger-wheeled N15 class counterparts.
The Leader was a class of experimental 0-6-0+0-6-0T steam locomotive, produced in the United Kingdom to the design of the innovative engineer Oliver Bulleid. The Leader was an attempt to extend the life of steam traction by eliminating many of the operational drawbacks associated with existing steam locomotives. It was intended as a replacement for the ageing fleet of M7 class tank engines still in operation on the Southern Railway (SR). Design work began in 1946 and development continued after the nationalisation of the railways in 1948, under the auspices of British Railways (BR).
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives.
No.6880 Betton Grange is a steam locomotive which is under construction as a "new-build" project, originally based on the Llangollen Railway in Denbighshire, Wales, then subsequently at Tyseley Locomotive Works. Described as "building the 81st Grange", the project started in 1998, and the locomotive was earlier expected to be operational by 2013, but subsequently by Autumn 2021, which was then pushed back to 2024. It was expected to be launched under steam in a private member event in January 2024 but was postponed a week before the event. All of the original GWR 6800 Class Grange locomotives were withdrawn for scrap by the end of 1965; this project is a creation, from an assemblage of original GWR and newly manufactured components, of a member of this class.
The South African Railways Class 14 4-8-2 of 1913 was a steam locomotive.
The South African Railways Class 12 4-8-2 of 1912 was a steam locomotive.
The GCR Class 2 steam locomotive was derived from a Kitson (Leeds) built/Thomas Parker designed prototype 4-4-0 locomotive No. 561, exhibited in Manchester in 1887. The design lead to the production of a series of express steam locomotives built between 1890 and 1894 for use on the Manchester, Sheffield and Lincolnshire Railway, later the Great Central Railway. The last batch of six, built 1894, had larger bearings for the coupled wheels, coil springs for the driving axle and was classified 2A.
