The London, Midland and Scottish Railway (LMS) 6170 (later 46170) British Legion was a British steam locomotive. It was the prototype for, and is sometimes considered a member of, the Rebuilt Royal Scot Class but differed from those later rebuilds principally in having a unique type 2 boiler, rather than a type 2A boiler, the two not being interchangeable.
6170 was constructed in 1935 utilising the frames of the unsuccessful experimental high pressure compound locomotive 6399 Fury. The Schmidt-Henschel boiler was replaced with a taper boiler, designed by William Stanier, and a new smokebox and inside cylinder were fitted. [1]
The locomotive was named after the British Legion and given a number as part of the Royal Scot Class. The boiler type was type 2.
It remained the only Class 6P rebuild until 1942 when two Jubilee Class engines 5735 Comet and 5736 Phoenix were also rebuilt with 2A boilers. After that, the LMS rebuilt all 70 of the Royal Scots, between 1943 and 1955 and 18 of the Patriot Class between 1946 and 1949 with 2A boilers. Thus 6170 was a prototype of a family of LMS 2A boilered 4-6-0s. When built, 6170 was given the standard passenger livery of LMS crimson lake and was the only rebuilt Scot to wear that livery whilst in service, though 6100 Royal Scot carries it in preservation.
There were numerous differences between 6170 and the other rebuilt Scots 6170's boiler was longer and it had a new cab with side windows, whereas the other rebuilt Scots retained their old cut-out cabs (the rebuilt Jubilees retained their original side window cabs and the rebuilt Patriots gained new side window cabs). It was the only rebuilt Scot built with a single chimney. Changes during its lifetime saw the fitting of a double chimney and smoke deflectors.
After nationalisation in 1948, 6170 was renumbered 46170. It was withdrawn in 1962 and subsequently scrapped.
The London, Midland and Scottish Railway (LMS) Princess Royal Class is a class of express passenger 4-6-2 steam locomotive designed by William Stanier. Twelve examples were built at Crewe Works, between 1933 and 1935, for use on the West Coast Main Line. Two are preserved.
The London, Midland and Scottish Railway (LMS) Coronation Class is a class of express passenger steam locomotives designed by William Stanier. They were an enlarged and improved version of his previous design, the LMS Princess Royal Class, and on test were the most powerful steam locomotives ever used in Britain at 2,511 dbhp. The locomotives were specifically designed for power as it was intended to use them on express services between London Euston and Glasgow Central; their duties were to include the hauling of a proposed non-stop express, subsequently named the Coronation Scot. The first ten locomotives of the Coronation class were built in a streamlined form in 1937 by the addition of a steel streamlined casing. Five of these ten were specifically set aside to pull the Coronation Scot. Although a later batch of five unstreamlined locomotives was produced in 1938, most of the ensuing Coronation class were outshopped as streamliners. From 1944 until production ended in 1948, all-new engines were built in unstreamlined form and all the streamliners had their casings removed. The last of the 38 locomotives was completed in 1948.
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.

The London, Midland and Scottish Railway (LMS) Jubilee Class is a class of steam locomotive designed for main line passenger work. 191 locomotives were built between 1934 and 1936. They were built concurrently with the similar looking LMS Stanier Class 5 4-6-0. They were nicknamed Red Staniers and Jubs.
The London, Midland and Scottish Railway (LMS) Royal Scot Class is a class of 4-6-0 express passenger locomotive introduced in 1927. Originally having parallel boilers, all members were later rebuilt with tapered type 2A boilers, and were in effect two classes.
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, Midland and Scottish Railway (LMS) No. 6399 Fury was an unsuccessful British experimental express passenger locomotive. The intention was to save fuel by using high-pressure steam, which is thermodynamically more efficient than low-pressure steam.
The Stanier Class 3P 2-6-2T was a class of London, Midland and Scottish Railway (LMS) steam locomotive. They were designed by William Stanier based on the earlier LMS Fowler 2-6-2T.

The SR U class are 2-6-0 steam locomotives designed by Richard Maunsell for passenger duties on the Southern Railway (SR). The class represented the penultimate stage in the development of the Southern Railway's 2-6-0 "family", which improved upon the basic principles established by GWR Chief Mechanical Engineer (CME) George Jackson Churchward for Great Western Railway (GWR) locomotives. The U class design drew from experience with the GWR 4300s and N classes, improved by applying Midland Railway ideas to the design, enabling the SECR to influence development of the 2-6-0 in Britain.

The Northern Counties Committee (NCC) Class U2 4-4-0 passenger steam locomotives consisted of 18 locomotives built for service in north-east Ireland. Ten of the engines were new builds supplied by the North British Locomotive Company (NBL) or constructed at the NCC's York Road works. The remainder were rebuilds of existing locomotives.
The SECR N1 class was a type of 3-cylinder 2-6-0 ('mogul') steam locomotive designed by Richard Maunsell for mixed traffic duties, initially on the South Eastern and Chatham Railway (SECR), and later operated for the Southern Railway (SR). The N1 was a development of the basic principles established by the Great Western Railway's (GWR) Chief Mechanical Engineer (CME) George Jackson Churchward and by Maunsell's previous N class design.
The SECR K class was a type of 2-6-4 tank locomotive designed in 1914 by Richard Maunsell for express passenger duties on the South Eastern and Chatham Railway (SECR), which operated between London and south-east England. The Southern Railway (SR) K1 class was a three-cylinder variant of the K class, designed in 1925 to suit a narrower loading gauge. They were among the first non-Great Western Railway (GWR) types to use and improve upon the basic design principles of power and standardisation established by GWR Chief Mechanical Engineer (CME) George Jackson Churchward. The locomotives were based on the GWR 4300 class, improved by the Midland Railway's ideals of simplicity and ease of maintenance.
The London Midland and Scottish Railway (LMS), Rebuilt Patriot Class was a class of 4-6-0 steam locomotives. They were rebuilt from LMS Patriot Class locomotives over the period 1946–1949. By the end of 1947, the LMS had rebuilt seven engines, these being 5514/21/26/29–31/40. After nationalisation, a further eleven locomotives were rebuilt. Rebuilt locomotives retained their numbers.
The London, Midland and Scottish Railway (LMS) Rebuilt Royal Scot Class is a class of 4-6-0 steam locomotives. 70 members of this class were rebuilt by the LMS and its successor British Railways (BR) from LMS Royal Scot Class engines by the replacement of their life expired parallel boilers with a type 2A boiler over the period 1943–1955.. They were the second class to be rebuilt with type-2 boilers, after the rebuilding of British Legion and the Jubilee Class.
The London, Midland and Scottish Railway (LMS) Rebuilt Jubilee Class consisted of two 4-6-0 steam locomotives.
The London, Midland and Scottish Railway (LMS) 2 and 2A boilered 4-6-0 locomotives were express passenger 4-6-0 steam locomotives. In 1935, William Stanier, Chief Mechanical Engineer of the LMS, ordered the rebuilding of the unique experimental high pressure compound locomotive 6399 Fury. The Schmidt-Henschel boiler was replaced with a tapered boiler, with a drumhead smokebox, designated type 2. The type 2 boiler had a tube surface of 1,669 square feet, formed by tubes 2⅛ inches in diameter and 14 feet 3 inches long. It was fitted with a 28 row superheater with 360 square feet of heating surface. The superheater elements, 1⅛ inch in diameter, were fitted into flue tubes 5⅛ inches diameter.
