The Vulcan Foundry was originally opened in 1830 at Newton-le-Willows, as Charles Tayleur and Company. It initially produced girders for bridges, switches and crossings, and other ironwork following the opening of the Liverpool and Manchester Railway. Robert Stephenson became a partner in 1832, and in the same year, the first locomotives ‘Tayleur’ and ‘Stephenson’ were delivered to the North Union Railway. By 1840 locomotives had been delivered to five European countries and to North America. The company became The Vulcan Foundry Company in 1847 and acquired limited liability in 1864. From the beginning of 1898, the name changed again to The Vulcan Foundry Limited, dropping the word 'company.' Vulcan locomotives were exported all over the world, with the first locomotives for Russia and Japan supplied in 1837 and 1871 respectively and a long association with India began in 1852. First World War production included shells, gun mountings and mine sweeping equipment. The first non-steam locomotive, an electric, was produced for India in 1929. The first diesel locomotive design commenced in 1932/33 and an agreement was reached with A/S Frichs in Denmark. The English Electric 6K engine was used from this time. The “Waltzing Matilda” tank was developed in 1938 and produced in large numbers and over five hundred ‘Austerity’ steam locomotives were produced for the War Department. Other wartime production included gun mountings and torpedo parts. In 1944 Vulcan acquired the locomotive business, Robert Stephenson & Hawthorns Ltd, based in Newcastle-upon-Tyne. In 1946 the company began working with the English Electric Company producing diesel and electric locomotives and became part of the English Electric Group in 1955. All locomotive building from Preston was transferred to Vulcan Foundry and Robert Stephenson’s in Darlington. Under the new ownership, the works produced many locomotives for both domestic and foreign railways, notably the Deltic. The mid-sixties saw the ‘RK’/’V’ engine production at Preston moved to Vulcan and Ruston & Hornsby Ltd merged with English Electric Diesels in 1966. After the General Electric Company plc (GEC) takeover in 1968 the Ruston name was used for some time inside what became GEC Diesels Ltd in 1975. Engine production and development continued for locomotive, industrial and marine applications until after the GEC-Alsthom merger in 1989. The company took over Mirlees Engines, Stockport in 1997 and was renamed Alstom Engines Ltd.

In 1937 Robert Stephenson & Co. Ltd purchased the locomotive department of R & W Hawthorn Leslie & Co. Ltd. They became Robert Stephenson and Hawthorns Ltd. The policy was to concentrate the building of main line locomotives at Robert Stephenson’s Darlington works and industrial locomotives at Forth Banks. In 1944 Vulcan Foundry acquired Robert Stephenson and Hawthorns Ltd, ending Hawthorns' 137 year connection with Forth Banks. In 1955 Vulcan Foundry became full members of the English Electric group of companies, which became part of the GEC group of companies in 1968.

The Phoenix Works in Bradford were owned Phoenix Dynamo Manufacturing Company of Hubert Street, Leeds Road in 1895 manufacturing arc lamps and electrical instruments. By 1900 the company works were manufacturing small motors and dynamos for driving machinery and providing lighting specifically for the textile industry. Large motors, turbines, turbo-generators etc. were manufactured for orders from the Admiralty and War Office. During the First World War, the works produced millions of shells, a large quantity of machine tools, sea planes and flying boats. In 1918 these works became the English Electric center for small to medium sized industrial AC and DC motors and generators including fractional horsepower machines and also eventually a specialised unit manufacturing generators and motors for aircraft applications. In 1930, the Dick, Kerr West Works at Preston closed and Traction electrical design and manufacture transferred to Bradford. Some key staff left and joined Crompton Parkinson. Important traction work included motors and generators for early diesel electric applications and continued manufacture of Metrovick designed motors for the Southern Railway. After the Second World War, most of the traction manufacturing transferred to the Preston East works factory but the design and commercial offices remained at Bradford until 1967. Some traction and associated military manufacturing work continued including conventional submarine control gear and pulse generators for mine sweepers. The Aircraft Equipment Division merged with Lucas Aerospace and left Bradford in the 1970’s and industrial machine manufacture ceased in the 90’s with complete closure in 1999. A B&Q store occupies the former Traction part of the site. An office block built in the 1950’s is all that remains of the factory.

The British Railways Board was an independent statutory corporation responsible for running the British railway network from 1963. It was established by the Transport Act 1962, which abolished the British Transport Commission and divided its undertakings between five newly-created bodies: the British Railways Board, the British Waterways Board, the British Transport Docks Board, the London Transport Board, and a Transport Holding Company. The British Railways Board was responsible for running the railway network, as well as managing government-owned railway hotels. Members of the British Railways Board were also appointed by the Minister for Transport. The first Chair of the British Railways Board was Dr Richard Beeching. The British Railways Board operated through regional boards, which were responsible for regional sections of the railway network. These regions were Southern, Western, London Midland, London and North Eastern, Eastern, and Scottish. Members of these regional boards were appointed by the British Railways Board, in consultation with the Minister for Transport. The British Railways Board also operated a series of committees to manage every aspect of railway control, including committees for finance, technical, works and property. These committees were frequently reorganised throughout the life of the British Railways Board, under both different Chairs of the Board and different governments. Several changes occurred during the 1960s. The Board had two new Chairs; Stanley Raymond, who replaced Richard Beeching in 1965, and his successor Henry Johnson, who became Chair in 1967. In 1968, the Transport Act transferred the control of the Sundries and Freightliner divisions from the British Railways Board to National Carriers Ltd and Freightliners Ltd. The Board retained a forty-nine per cent stake in Freightliners Ltd. During the 1970s, the British Railways Board created several subsidiary companies which were to manage some of its undertakings. These included British Transport Hotels Ltd, British Rail Engineering Ltd, and British Rail Hovercraft Ltd. Many of these subsidiary companies were sold under the Conservative governments of the 1980s. There were also two new Chairs during this time. Richard Marsh replaced Henry Johnson in 1971, and Peter Parker became chair in 1976. The privatisation of the British rail network during the 1990s radically changed the role of the British Railways Board. The Transport Act 1993 established Railtrack, a publicly-owned company. The Act transferred the ownership of track and railway infrastructure from the British Railways Board to Railtrack, in addition to the control of signals. Railtrack also replaced the British Railways Board as the body responsible for track investment and maintenance. The British Railways Board remained in existence after these changes, but only performed residual functions relating to pensions, liabilities, and non-operational railway land. The Board also continued to operate the British Transport Police service. The British Railways Board was abolished by the Transport Act 2000, which transferred the remaining functions of the Board to the newly-created Strategic Rail Authority.
