The London, Midland and Scottish Railway had the largest stock of steam locomotives of any of the 'Big Four' Grouping, i.e. pre-Nationalisation railway companies in the UK. Despite early troubles arising from factions within the new company, the LMS went on to build some very successful designs; many lasted until the end of steam traction on British Railways in 1968. For an explanation of numbering and classification, see British Rail locomotive and multiple unit numbering and classification.
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 Caledonian Railway 812 and 652 Classes were 0-6-0 steam tender locomotives designed by John F. McIntosh for the Caledonian Railway and introduced in 1899. They had the same boiler type as the 721 “Dunalastair” Class 4-4-0s. They could reach speeds of up to 55 mph.
The Caledonian Railway 60 Class were 4-6-0 passenger engines designed by William Pickersgill and introduced in 1916. Six were built by the Caledonian Railway at its own St. Rollox works in 1916–17, and all of them passed into LMS ownership in 1923. A further twenty locomotives of a slightly modified design were built by the LMS under the auspices of George Hughes in the period of 1925–1926.
The Caledonian Railway 956 Class were 3-cylinder 4-6-0 steam locomotives that were used on the Caledonian Railway from 1921. They were built to the design of William Pickersgill. At the time they were the largest design operated by a Scottish railway.
The London, Midland and Scottish Railway (LMS) Hughes Crab or Horwich Mogul is a class of mixed-traffic 2-6-0 steam locomotive built between 1926 and 1932. They are noted for their appearance with large steeply-angled cylinders to accommodate a restricted loading gauge.
The London, Midland and Scottish Railway (LMS) Ivatt Class 2 2-6-0 is a class of steam locomotive designed for light mixed traffic.
The Glasgow and South Western Railway (G&SWR) 403 Class was a class of 2-6-0 (mogul) steam locomotive designed by Peter Drummond, of which 11 were built in 1915 by the North British Locomotive Company at its Queens Park works. Originally built as the 403 class, as a result of renumbering they became known as the 33 Class in 1916 and then 51 Class in 1919, before passing to the London Midland and Scottish Railway (LMS) on its formation in 1923, where they were given power classification 4F.
The locomotives of the Highland Railway were used by the Highland Railway to operate its lines in the north of Scotland. The Highland Railway locomotive works was at Lochgorm, Inverness. The works had been built about 1855 by the Inverness and Nairn Railway. The locomotive classes are listed under the names of the railway's Locomotive Superintendents.
The Caledonian Railway 721 Class was a class of 4-4-0 steam locomotives designed by John F. McIntosh for the Caledonian Railway (CR) and introduced in 1896. All survived to be absorbed by the London, Midland and Scottish Railway (LMS) in 1923 and a few survived into British Railways (BR) ownership in 1948.
The Caledonian Railway 179 Class was a class of 4-4-0 steam locomotives designed by George Brittain for the Caledonian Railway (CR) and introduced in 1882.
The Caledonian Railway 179 Class and 184 Class were 4-6-0 mixed-traffic locomotives designed by John F. McIntosh and built in two batches in 1913-14 and 1914-15 respectively, at the Caledonian Railway's own St. Rollox Works. The differences between the two batches were minor, and they are often considered to be a single class.
The Caledonian Railway 49 Class and 903 Class were 4-6-0 express passenger locomotives designed by John F. McIntosh and built at the Caledonian Railway's own St. Rollox Works in 1903 and 1906 respectively.
The Caledonian Railway 55 Class were 4-6-0 mixed-traffic locomotives designed by John F. McIntosh and built at the railway’s St. Rollox works in Glasgow in 1902-1905. The class was intended for use on the Callander and Oban line and were sometimes known as Oban Bogies, a nickname they shared with the earlier Brittain 179 Class 4-4-0s and the subsequent Pickersgill 191 Class 4-6-0s, all of which were built for use on the same route.
The Caledonian Railway 908 Class were 4-6-0 mixed traffic locomotives designed by John F. McIntosh and built in 1906, at the Caledonian Railway's own St. Rollox Works.
The Caledonian Railway 918 Class were 4-6-0 steam tender locomotives designed by John F. McIntosh and built in 1906, at the Caledonian Railway's own St. Rollox Works.
The Glasgow and South Western Railway 540 Class were 4-6-4T steam tank locomotives designed by Robert Whitelegg and built in 1922, shortly before the G&SWR was absorbed into the London, Midland and Scottish Railway (LMS). They were referred to in official G&SWR publicity as the Baltic Class, although they were also known more prosaically to enginemen as the 'Big Pugs'.
The Caledonian Railway 944 Class were 4-6-2T passenger tank locomotives designed by William Pickersgill and built in 1917, at the North British Locomotive Company's Hyde Park Works in Glasgow. They were the Caledonian Railway's only pacific-type.
The Glasgow and South Western Railway (G&SWR) 279 class was a class of 0-6-0 steam locomotive designed by Peter Drummond, of which 15 were built in 1913 by the North British Locomotive Company at its Queens Park works. Originally built as the 279 class, as a result of renumbering they became known as the 71 class in 1919, before passing to the London Midland and Scottish Railway (LMS) on its formation in 1923, where they were given power classification 4F.
The Glasgow and South Western Railway (G&SWR) 131 Class and 137 Class were two closely related classes of 4-4-0 steam locomotives designed by Peter Drummond. A total of 12 locomotives were built between 1913 and 1915, with some constructed by the North British Locomotive Company (NBL) at its Queens Park works and others by the G&SWR at its Kilmarnock works. Originally designated as the 131 and 137 classes, the locomotives were later renumbered and became known as the 331 and 325 classes, respectively, in 1919. Following the formation of the London Midland and Scottish Railway (LMS) in 1923, the locomotives were transferred to the LMS, where they were classified as 3P in terms of power rating.
