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.
4-4-0 is a locomotive type with a classification that uses the Whyte notation for the classification of steam locomotives by wheel arrangement and represents the arrangement: four leading wheels on two axles, four powered and coupled driving wheels on two axles, and a lack of trailing wheels. Due to the large number of the type that were produced and used in the United States, the 4-4-0 is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced.
The London, Midland and Scottish Railway (LMS) Fairburn Tank 2-6-4T is a class of steam locomotive. They were designed by Charles E. Fairburn for the LMS. 277 of these locomotives were built between 1945 and 1951, numbered in the range 42050–42186, (4)2187–(4)2299, (4)2673–(4)2699.
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 300 Class were freight 0-6-0 tender engines introduced in 1918 and designed by William Pickersgill. Forty-three were built between 1918 and 1920. They were numbered 294–324, 280, 281, 670–679 by the Caledonian 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.
William Pickersgill was an English railway engineer, and was chief mechanical engineer of the Caledonian Railway from 1914 until Grouping in 1923. He was appointed locomotive superintendent of the Northern Division of the London, Midland and Scottish Railway but retired in 1925. He died in Bournemouth.
Dugald Drummond was a Scottish steam locomotive engineer. He had a career with the North British Railway, LB&SCR, Caledonian Railway and London and South Western Railway. He was the older brother of the engineer Peter Drummond, who often followed Dugald's ideas in his own work.
Caledonian Railway Single No. 123 is a preserved Scottish steam locomotive. The unique 4-2-2 was built by Neilson and Company in 1886, works No. 3553, as an exhibition locomotive. In 1914 it was placed on the Caledonian Railway duplicate list, and renumbered 1123. It entered London, Midland and Scottish Railway service in 1923 and the LMS renumbered it 14010 and gave it the power classification 1P. During the 1920s it was allocated to working the directors' saloon, but it was returned to ordinary service in 1930. The locomotive was withdrawn in 1935, by which time it was the last single-wheeled express engine running in Britain, and set aside for preservation.
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.
John Farquharson McIntosh (1846-1918) was a Scottish engineer. He was Chief Mechanical Engineer of the Caledonian Railway from 1895 to 1914. He was succeeded by William Pickersgill.
Locomotives of the Caledonian Railway. The Caledonian Railway Locomotive Works were originally at Greenock but moved to St. Rollox, Glasgow, in 1856. The locomotive classes are listed under the names of the railway's Chief Mechanical Engineers.
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 G&SWR 5 Class were 0-6-0T steam locomotives designed by Peter Drummond for the Glasgow and South Western Railway (G&SWR) and introduced in 1917. The class was originally designated 5 Class but, after the G&SWR's 1919 renumbering, this was changed to 322 Class. After passing to the London, Midland and Scottish Railway (LMS) in 1923 they were given power classification 2F.
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 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.
