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.

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.

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.
