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 London, Midland and Scottish Railway (LMS) pioneered the use of diesel shunting locomotives in Great Britain. The variety of experimental and production diesel shunters produced by the LMS is summarised below.
A number of different numbering and classification schemes were used for the locomotives owned by the London, Midland and Scottish Railway (LMS) and its constituent companies; this page explains the principal systems that were used.
The Patriot Class was a class of 52 express passenger steam locomotives built for the London Midland and Scottish Railway. The first locomotive of the class was built in 1930 and the last in 1934. The class was based on the chassis of the Royal Scot combined with the boiler from Large Claughtons earning them the nickname Baby Scots. A total of 18 were rebuilt to create the LMS Rebuilt Patriot Class between 1946 and 1948; thereafter those not subjected to rebuilding were often referred to as the Unrebuilt Patriot Class. These remaining 34 unrebuilt engines were withdrawn between 1960 and 1962.
The London and North Western Railway (LNWR) Improved Precedent Class or Renewed Precedent Class is a class of 2-4-0 steam locomotives originally designed for express passenger work. They later gained the nickname of Jumbos.
The London and North Western Railway (LNWR) Prince of Wales Class was a class of express passenger locomotive. It was in effect, a superheated version of the Experiment Class 4-6-0.
The London and North Western Railway (LNWR) George the Fifth Class was a class of 4-4-0 passenger steam locomotive.
The London and North Western Railway (LNWR) "Precursor" Class was a type of 4-4-0 ("American") steam locomotive designed by the company's Chief Mechanical Engineer, George Whale. Introduced in 1904, it should not be confused with the LNWR 2-4-0 "Precursor" Class of 1874 designed by Francis Webb, the last example of which was scrapped in 1895. In 1906, a 4-4-2T ("Atlantic") tank variant of Webb's engine, the "Precursor Tank" Class, also entered service.
The London and North Western Railway (LNWR) Experiment Class was a class of 4-6-0 steam locomotive designed by George Whale.
The London and North Western Railway (LNWR) Claughton Class was a class of 4-cylinder express passenger 4-6-0 steam locomotives.
The London and North Western Railway (LNWR) Jubilee Class was a class of 4-4-0 4-cylinder compound locomotives by F.W. Webb. A total of forty were built from 1897–1900. Slightly unusually for the LNWR, the class received a number series, this being 1901–1940.
The London and North Western Railway (LNWR) Alfred the Great class, after modification known as the Benbow Class was a class of 4-4-0 4-cylinder compound locomotives by F.W. Webb. A total of forty were built from 1901–1903. They were a development of the Jubilee Class, with a slightly larger boiler.
The London and North Western Railway (LNWR) Class B was a class of 0-8-0 steam locomotives introduced in 1901. A development of the three-cylinder compound Class A, they had a 4-cylinder compound arrangement. 170 were built between 1901 and 1904.
The London and North Western Railway (LNWR) Class C was a class of 0-8-0 steam locomotives. They were two cylinder simple expansion rebuilds of the three-cylinder Class A designed by F.W. Webb. Fifteen Class As were converted to Class C between 1904 and 1906 by George Whale.
The London and North Western Railway (LNWR) Class C1 was a class of 0-8-0 steam locomotives. 34 were rebuilt by Charles Bowen Cooke from Class A 3-cylinder compounds between 1909 and 1912.
The London and North Western Railway (LNWR) Class D was a class of 0-8-0 steam locomotives. They were simple engine rebuilds of earlier Webb Class A three-cylinder compound engines.
The London and North Western Railway (LNWR) Waterloo Class was a class of 2-4-0 steam locomotives that was also known as the Whitworth Class.
The London and North Western Railway (LNWR) Class G1 was a class of 0-8-0 steam locomotives. It was a superheated version of the LNWR Class G with 8 inch piston valves. The prototype was rebuilt in 1912 from a member of Class G and a further 170 new locomotives were built between 1912 and 1918. In addition, 278 older locomotives were rebuilt to the G1 specification between 1917 and 1934.
The LNWR 18-inch Goods was a class of 310 0-6-0 freight steam locomotives built by the London and North Western Railway at their Crewe Works between 1880 and 1902.
