During the First World War the government had taken control of the railways to co-ordinate the war effort. After the war ended it was decided that the railway companies could not competitively return to their prior state, and so the 120 existing railway companies were combined into four companies, which became known as the ‘Big Four’’. The London Midland and Scottish Railway, also known as the LMS, was founded on 1 January 1923. The London and North Western Railway (LNWR), Midland Railway (MR), Lancashire and Yorkshire Railway (LYR), North Staffordshire Railway (NSR), Highland Railway (HR), Furness Railway (FR), Glasgow and South Western Railway (G&SWR) and Caledonian Railway (CR) were merged. These eight large constituent companies were joined by 27 other smaller subsidiary railways. The LMS covered the Western half of the country, stretching from the London and the Midlands, through Yorkshire, Lancashire, and up to Scotland. In all the LMS had a total of 7,790 miles of track, which made it the largest railway of the Big Four. The London termini of the LMS were St. Pancras and Euston stations and it had works at Crewe, Horwich, Wolverton and Derby amongst other locations. In 1934 the LMS moved into a new headquarters at Euston House on Seymour Street (later renamed Eversholt Street) in London. Charles Napier Lawrence, 1st Baron Lawrence of Kingsgate was the first appointed chairman of LMS, he had previously been the chairman of the LNWR between 1921-1923. He was chairman of the LMS for one year, and was succeeded by Sir Guy Granet. The management structure was headed by a chairman and a deputy chairman, there was a board of directors that had initially had 20 members, made of men who previously worked for the constituent companies. The first General Manager was Arthur Watson from the LYR. There was a Deputy General Manager for Scotland, a post first held by D.A. Matthieson, formerly of the CR. J.H. Follows, from the Midland Railway, was the first Chief General Superintendent and S.H. Hunt, formerly of the LNWR, was the first Chief Goods Manager. The post of Chief Engineer was initially held by E.F.C. Trench, formerly employed by the LNWR. The first Chief Mechanical Engineer was G. Hughes from the LYR and his deputy was Sir Henry Fowler, from the Midland Railway. The management structure was re-organised from January 1926 and an Executive was set up, Sir Josiah Stamp was the first President of the Executive. From January 1927 four Vice-Presidents were appointed to replace the general managers on the Executive committee. The line was divided up for operational management into three geographical divisions, which were called Western, Midland and Northern. Each division was overseen by a General Superintendent who reported to the Chief General Superintendent. The main line of the LMS ran from London Euston to Wick over 729 miles. The LMS ran a number of joint railways with the London & North Eastern Railway and the Southern Railway. It ran the Cheshire Lines Committee, the Midland and Great Northern line between Peterborough, the Norwich and Lowestoft and the Manchester, South Junction and Altrincham suburban line with the London & North Eastern Railway. It also joined forces with the Southern Railway to run the Somerset and Dorset line between Bath, Burnham and Bournemouth. The LMS undertook a limited programme of electrification, mainly focusing on suburban lines in London and Manchester. The LMS owned many hotels, including the Queen’s Hotel in Leeds and the iconic Art Deco Midland Hotel at Morecombe Bay. The LMS also ran passenger steamers from Holyhead, Heysham and Stranraer over the Irish Sea to Northern Ireland and the Republic of Ireland. Following the 1947 Transport Act which nationalised the railways, the concerns of the LMS were taken over by the Railway Executive as part of the British Transport Committee. Within the Railway Executive, British Rail: London Midland Region assumed responsibility for the LMS’s former area of operations.

Lister Blackstone was formed through the acquisition of Black-stone & Co by R A Lister & Co (1867), in Stamford who was an agricultural implement manufacturer in 1936. Following the takeover a period of reorganisation of the factory and the production methods occurred as Lister had originally acquired Blackstone in order to gain access to the large engine market. During the Second World War, all production of open crank spring injection engines, small vertical petrol, kerosene and diesel engines and BPV automotive engines were stopped. In particular, the production of EPV engines for base load installations was increased to meet the demand from all three Services and the demand increased for productivity on agricultural implements. Lister Blackstone was run as an independent family business until 1st June 1965 when it was taken over by the Hawker Siddeley Group and merged with Mirrlees National of Stockport four years later. The company name changed to Mirrlees Blackstone Ltd in 1969.

“British Railways” is the expression commonly used to describe the business run by the following legal entities: • Railway Executive (1948 – 1952) • British Transport Commission (1952 – 1963) • British Railways Board (1963 – 1993) Railways were nationalised on 1st January 1948 when the assets of the railways in Great Britain were vested in the British Transport Commission (BTC), a state-owned corporation created by the Transport Act 1947. Between 1948 and 1952 the business of operating the railways was carried on by the Railway Executive, a state-owned corporation, subsidiary to BTC. The Railway Executive was abolished in 1952 and BTC took over direct responsibility for the railways. Before 1948 there was no brand that was identified with the whole of the railways of Great Britain, only the separate brands of the Group companies, Southern, Great Western, London, Midland and Scottish and London and North Eastern, and London Transport. The railways were run under the corporate identity “British Railways” from 1948 by both the Railway Executive and BTC. The public manifestations of this were the words themselves on vehicles and premises, quasi-heraldic devices on locomotives (the so-called “cycling lion” followed by the “ferret and dartboard”) and the lozenge shape adopted (and clearly inspired by London Transport’s very similar logo) for station names. When the nationalised transport industry was reorganised in 1963, BTC was itself abolished and a new statutory corporation created to run the railways. This was British Railways Board (BRB). The name most closely associated with the national railway system had now become part of the name of the corporate entity, (i.e. the legal person, entitled as a matter of law to own property, to enter into contracts, and to sue (or be sued) in the courts and be prosecuted for breaches of the criminal law) which owned the assets and business of the railways of Great Britain. As a result of the corporate rebranding carried out in 1965 the business name, or brand name (as it was now expressly recognised to be), was shortened to “British Rail”. However, BRB retained the full “British Railways” in its title until its eventual abolition under the provisions of the Transport Act 2000.
