Walter T Glover established his wire manufacturing company in 1868, occupying premises at the Bridgewater Street Iron Works in Salford. W T Glover & Co, known as Glover’s, originally made cotton-covered and braided, insulated copper wires for use on bell, signalling and telephone circuits. As trade developed, the company moved to the Springfield Lane Cable Works in 1880. At this time, factories and larger private homes were beginning to install electric lighting, which required better insulated cable. Glover's started to manufacture cables covered with between one and three layers of rubber strip, waterproof tape and compounded cotton braid. In the late 1880s, Glover's began to make lead-sheathed cables for underground use. The company became a limited company and moved to Trafford Park in 1898, securing the exclusive rights for the supply of electricity to all the roads, streets and premises of Trafford Park. In June 1919, Vickers Ltd took over Glover's. Although Vickers held most of the shares, Glover's kept its name and management. In 1929 the Vickers group reorganised and sold its shares in Glover's to Sir Tom Callendar of Callendar Cable and Construction Co. Some shares later went to W. T. Henley's Telegraph Works Ltd. and British Insulated Cables. In 1945, Glover’s became part of British Insulated Callenders Cables Limited, following the merger of Callenders Cable and Construction Co and British Insulated Cables. During the 1950s, Glover’s developed high voltage submarine power cables, used to link centres of population with sources of generation. The parent company formed a subsidiary, BIC (Submarine) Cables Ltd, to manufacture and install the Glover’s cables. Glover's submarine cables linked England and France, and the north and south islands of New Zealand. Increasing competition from other cable manufacturing companies resulted in the south side of Glover’s Trafford Parks works integrating with the newly formed Wiring and General Cables Division of the British Insulated Cables Company (BICC). The Trafford Park factory closed in 1970, but the Glover’s brand continued as part of BICC.

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.
