The English Electric Company was formed on 14th December 1918 and over the following year acquired Dick, Kerr & Company of Preston, Willans & Robinson of Rugby, the Phoenix Dynamo Manufacturing Company of Bradford, and Coventry Ordnance Works. After the First World War the various German owned Siemens works were distributed to different UK companies and in November 1919 English Electric acquired the Siemens Brothers Dynamo Works at Stafford, which became the company headquarters in 1931. Coventry Ordnance, primary output naval guns, did not feature in the gradual product rationalisation which took place between the First World and Second world Wars. Willans & Robinson’s Rugby works specialised in prime movers, steam, hydro and internal combustion, and their Stafford works on power station and distribution electrics, including transformers and large electric machines for applications such as mining and steel works. Dick Kerr & Company continued building equipment and vehicles for bus, tram and railway applications with the Phoenix Dynamo Manufacturing Company concentrating on medium and small electrical machines. Involvement with aircraft continued a small scale. By 1929 the company was in financial trouble and an American syndicate fronted by Lazard Bros. put in new capital. In 1930 Westinghouse of Pittsburgh entered into an agreement with the company for the exchange of technical information relating to steam turbines and electrical apparatus. This cooperation continued into the 1950s. 1930 saw the closure of Preston West works and the transfer of traction electrical design and manufacture to the Phoenix Dynamo Manufacturing works. The Westinghouse influence included top management changes with Sir H Mensforth becoming chairman and George Nelson managing director. Both had been with British Westinghouse at Trafford Park. The early 1930s saw a remarkable improvement in the company’s finances and domestic appliance manufacture was started at Bradford and Stafford. In 1936 they began production of diesel locomotives at Preston and were later involved in the production of the Deltic locomotive for British Rail, presaging the end of steam traction in the UK. Extensive shadow factory building for war production commenced in the late 1930’s, including at Preston East works and Salmesbury for aircraft production and at East Lancashire Road, Liverpool for D. Napier aero engines. A large variety of military equipment built during the war included thousands of Cromwell tanks from Stafford and over 3000 Handley Page Hampden and Halifax bombers from Preston and Salmesbury. After the war manufacture of smaller products from Bradford and Stafford moved to the large Liverpool works. This included electrical distribution transformers, switchgear, fuse gear, fractional horsepower motors and domestic appliances. Napier’s continued engine manufacture with the development of the ’Deltic’ diesel engine, mainly for marine applications. The nearby Netherton works took over the manufacture of large hydro-electric turbines and generators from Willans and Stafford. In 1942 English Electric acquired D. Napier & Son Ltd and Marconi in 1946. The company went on to extend their railway interests with the acquisition of the Vulcan Foundry and Robert Stephenson and Hawthorn Ltd in 1955. The company tried to take over The General Electric Company (GEC) in 1960 but failed. Traction manufacture, but not the offices, moved back to Preston East works and ‘K’, ‘RK’ and ‘V’ engine design and manufacture moved from Willans to Preston West works which was now also used for locomotive building. Kidsgrove works in Stafford made industrial controls and for a while was a major player in the UK computer industry, merging with Leo Computers and then into ICL. Train performance calculations were an early user of the mid-fifties ‘Deuce’ computer. Preston also became a major player in the aircraft industry taking over the wartime RAF/USAF base at Warton aerodrome - major design and manufacture contracts included Canberra bombers and Lightning fighters. Rationalisation in the 1960s resulted in English Electric Aviation becoming 40% of the new British Aircraft Corporation. In 1961 English Electric took over Dorman Diesels Ltd which in turn had acquired W. G. Bagnall Ltd. In 1966 English Electric Diesels merged with Ruston and Hornsby which already included Paxmans. This company eventually became GEC Diesels. Elliott Automation was acquired in 1967. The following year GEC took over English Electric, ending its independent existence.

In 1962, the English Electric Company Ltd amalgamated the locomotive-building activities of their already-owned Vulcan Foundry (Newton-le-Willows Works) and its subsidiary Robert Stephenson & Hawthorns (Darlington Works), and W. G. Bagnall Ltd (Castle Engine Works, Stafford) under one management and a new wholly-owned subsidiary was formed named English Electric Traction. W. G. Bagnall Ltd was bought from W H Dorman in 1962 and effectively closed. The RSH works at Darlington ceased vehicle building in 1964. Vulcan Foundry was left as the only site for in-house locomotive building at the end of this period of contraction and rationalisation. It also took over manufacture (from Preston) of the range of EE diesel engines for railway locomotive use under the EE Diesels name. English Electric Traction initially operated from two Works to produce electrical equipment for locomotives and multiple-unit trains. These were in Preston (Strand Road, formerly Dick Kerr Works), and Bradford (Phoenix Dynamo Works). The Bradford works had done design work and manufacture of control gear as part of EE since 1930, but this activity was rationalised after 1962 and incorporated into the Preston operation by 1967, when the transfer of design engineering and commercial activities and staff was completed. The Preston works became the HQ centre for traction equipment (both control gear and motors), scheme design, building and testing. This equipment was sent to independent vehicle builders, to vehicle-builders in-house (i.e. at Vulcan Foundry or RSH), to overseas constructors, or to the British Rail workshops. The EE Stafford works was only engaged in traction activity is a minor way, principally as in-house supplier of main transformers and tap-changers, e.g. for 25kV locomotives, and some research and development activities on HV equipment. It was never part of EE Traction itself. The EE-AEI agreement, in the early sixties, resulted in joint electric loco production, for British Rail (Class 86), Poland, Pakistan and South Africa - 5E's were EE, 5E1's MV and after that joint production of electrical equipment with build of the mechanical parts in South Africa. English Electric Traction merged with AEI Traction Division in 1969 to form English Electric - AEI Traction, which subsequently became GEC Traction in 1972.

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.

The New Zealand Railways Department (NZR) also known as New Zealand Government Railways was a government department created in 1880. NZR acquired a number of private railways from 1886, including the Waimea Plains Railway Company and the New Zealand Midland Railway Company in 1898. The acquisition in 1908 of the Wellington and Manawatu Railway Company and its railway line marked the completion of the North Island Main Trunk from Wellington to Auckland after 23 years construction. In 1923 the West Coast line opens with the Otira tunnel containing the nation's first electric railway. In 1945 the South Island main trunk from Christchurch to Picton is completed and by 1953 the rail network reached its peak in terms of network reach at 5,689 kilometres. Between 1959 and 1971 numerous country branch lines close across the country as the steam era ends as NZR re-equipped lines with modern diesel locomotives. The NZR was reorganised in 1982 to become an independent commercial company called the New Zealand Railways Corporation.

Queensland Rail Limited also known as Queensland Government Railways was established in 1865. The railway stretched from coastal ports such as Brisbane, Cairns and Rockhampton, inland for the transportation of farming produce for exportation. The first railway line was built from Ipswich inland to Grandchester in 1864 and the first passenger train service ran on 31 July 1865. The line was extended to Darling Downs and Brisbane in 1875. Between 1899 and 1915, a large network of privately owned railways lines was built by mining magnate, John Moffat, which included Mungana, Mount Molloy, Mount Garnet, Mount Mulligan and the Etheridge mining field. As a result of falling share and copper prices, the Queensland Government took over these railway lines in 1919. A major restructure on 1st July 1991 with the introduction of the Transport Infrastructure (Railways) Act meant that Queensland Rail would begin to operate on a commercial basis as a State owned corporation. In accordance with the Queensland Rail Transit Authority Act 2013 (QRTA Act), Queensland Rail ceased being a government owned corporation from the 3rd May 2013 and the company became a wholly-owned subsidiary of this statutory authority.

RENFE (Spanish National Railways Network) was created in 1941, with the unification of the existing railway companies in Spain into a single state-owned company. In 1975, RENFE began a period of comprehensive reforms for the purpose of turning the Spanish railway network into an efficient alternative for transporting goods and passengers. As a result, Cercanías commuter services were introduced to cities such as Madrid, Barcelona and Malaga. In 1992 RENFE opened the Madrid-Seville high-speed line, coinciding with the opening of Expo'92. On 1 January 2005, RENFE’s legal monopoly came to an end and two successor companies were established; Renfe, responsible for transport of freight and passengers and Adif (Administrador de Infraestructuras Ferroviarias) responsible for managing lines, stations and communications. RENFE was divided into Renfe-Operadora (operations) and ADIF (infrastructure) on 1 January 2005.

Sudan Railways is the main railway system in Sudan, operated by the government-owned Sudan Railways Corporation. It runs over 5000km of narrow gauge, single-track railroads that serve the northern and central parts of the country. The main line underwent construction in 1875, completed in 1899, and runs from Wadi Halfa to Khartoum, and southwest to Al Ubayyid via Sannar and Kosti. In 1904-5 a line between Swakin and Atbara was constructed with the two lines meeting at Saloom station, to facilitate export and import transportation. In 1906 the railway headquarters and workshops were moved from Wadi Halfa to Atbara, and since 1981 the company headquarters have been based in Khartoum. In the 1980’s Sudan Railways declined due to political instability and debt, with lines operating at only 20% capacity by 1989. In 2011-2012 a contract was signed to build a line from Nyala to Chad, extending to the capital of Chad, N’Djamena. In 2015 Sudan Railways had 60 trains available but which could only travel at 40km per hour due to poor track conditions, with President Omer Hassan al-Bashir promising modernisation of the Sudanese railways with Chinese funding.

In 1948 the Kenya Uganda Railways & Harbours and the Tanganyika Railways & Port Services were merged and became the East African Railways & Harbours Corporation. In 1956 the EAR&H extended the Uganda Railway from Kampala to Kasese and to Arua in 1964. In 1977 the East African Community dissolved and EAR&H split into three national railways; the Uganda Railways Corporation, Tanzania Railways Corporation and Kenya Railways Corporation.
