In 1988 a joint-venture was formed between the General Electric Company (GEC) with Compagnie Générale d’Electricité (CGE) that led to the establishment of an Anglo-French company, GEC Alsthom in 1989. This company encompassed the Power Generation and Transmission, Rail Transport (25%) businesses from the constituent companies of GEC and CGE. The GEC Alsthom company headquarters were based at Rugby, Warwickshire and the headquarters for Transport were based at Trafford Park in Manchester. GEC Alsthom purchased train builder Metro-Cammell based at Washwood Heath, Birmingham from the Laird Group in 1989, bringing into the group a company which had a long association with GEC Traction and its predecessors as a vehicle builder. In 1998 GEC Alsthom was re-formed and became Alstom with Transport / Alstom Transport one of its major divisions.

GEC Alsthom Traction was formed from the merger of GEC and Alcatel-Alsthom (formerly known as Compagnie Générale d’Electricité of France) in 1989, which created a Joint Venture of their Power Engineering businesses (Power Stations, Switchgear and Rail Transport). The UK headquarters of the traction business was based at Trafford Park in Manchester. GEC Alsthom purchased train builder Metro-Cammell based at Washwood Heath, Birmingham from the Laird Group in 1989, bringing into the group a company which had a long association with GEC Traction and its predecessors as a vehicle builder. GEC Alsthom Traction became part of the Transport Equipment Group (TEG) with the French sites Ornans (motors), Tarbes (control equipment) and Villeurbanne (electronic systems, converters and control equipment), later joined by ACEC Transport (Charleroi). A major project in this period was the design and build of the Trans Manche Super Train (TMST) for London. TMST, later known as Eurostar Class 373, was the first TGV with asynchronous traction drive, all TGVs until later Duplex fleets having DC or synchronous traction drives. It was designed for three voltages 750v DC for the UK Southern Region, 3000v DC for Belgium and 25kV for the tunnel and France, and later for HS1 high speed line from the tunnel to London. SNCF later added 1500v DC to 4 trains to allow the trains to run to the Alps. In 1993, as part of the rationalisation of the equipment group, it was announced that the headquarters of GEC Alsthom Traction would move to Preston, leaving only Power Module design and manufacture at Manchester, and a project team was set up at Preston for the regeneration of the Preston site, with the eventual closing of all activities at Trafford Park in 1998. At the same time, there was rationalisation of product lines in the equipment group, with inductors and auxiliary converters moving to Preston, traction motor design concentrated at Ornans, switchgear at Tarbes and electronic control systems at Villeurbanne. GEC Alsthom Traction became Alstom Traction on 22nd June 1998 and the company name survived to 19th August 2008 but was increasingly integrated within the Transport division of Alstom.

Associated Electrical Industries (AEI) was formed in 1928 as a financial holding company for a number of leading electrical manufacturing and trading companies in the United Kingdom. The two major constituent companies were British Thomson-Houston (BTH) based at Rugby, (Mill Road Works) and Metropolitan-Vickers Electrical Company Ltd (Metrovicks) situated at Trafford Park, Manchester. However, fierce rivalry existed between the Metrovick and BTH brands resulting in internal competition and duplicated management. This was highlighted during the Second World War in 1939, when Metrovicks and BTH became the first two firms in the world to construct jet engines (independently from each other). Following the Second World War, in 1954, AEI expanded to consist of BTH, Metrovicks, Edison Swan Electric Co, Ferguson Pailin, Hotpoint Electric Appliance Co, International Refrigerator Co, Newton Victor, Sunvic Controls, Premier Electric Heaters, Siemens Bros (1955) and Birlec (1954). In 1959 AEI decided to remove the familiar brands of BTH and Metrovicks and consolidate both as AEI resulting in internal problems and a fall in sales and market value. However, AEI acquired a variety of companies from 1959 to 1967, these included Associated Insulation Products, W. T. Henley’s Telegraph Works Co (1958), and London Electric Wire Co and Smiths (1958), Submarine Cables, Hackbridge Holdings Ltd., The Lancashire Dynamo and Crypto Ltd., W.T. Avery Ltd., Henley and Schreiber. The General Electric Company bought AEI in 1967.

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.

The General Electric Company (GEC) merged AEI Traction Division and English Electric Traction in 1969 after acquiring both companies to create English Electric – AEI Traction Limited. The headquarters were located at Trafford Park in Manchester. This subsidiary company was renamed GEC Traction Limited in 1972.

The British Thomson-Houston Co. Ltd., (BTH) was created as a subsidiary of the General Electric Company, USA in 1896 to exploit the sale of products in the United Kingdom. BTH was a reconstruction of an existing firm, Laing, Wharton and Down (1886). The BTH manufacturing works were based at Rugby, Warwickshire and the company’s products included induction motors, alternators, switchgear, turbo-generators and turbines, as well as a large number of rotary converters and motor converters, primarily for chemical plants. During the First World War, BTH’s most significant contribution was the development of marine apparatus for the naval service. The 1920s saw a period of vast expansion for the company with new extensions built at many of its factories such as Willesden, Birmingham, Chesterfield and Lutterworth. BTH amalgamated with Metropolitan-Vickers Electrical Company Ltd to form Associated Electrical Industries (AEI) in 1928 although both companies retained their separate identities and continued to compete for the same contracts. BTH developed manufactured electric torpedoes and electrical components for aircraft engines, munitions, etc., during the Second World War and in 1935 independently of each other, BTH and Metropolitan-Vickers were the first two companies in the world to construct jet engines.

Metropolitan-Vickers Electrical Co Ltd was the new trading name given to British Westinghouse Electric and Manufacturing Co on 8 September 1919. The predecessor company had sold its controlling share to the Metropolitan Carriage Wagon Co in 1916 in order to gain membership of the Federation of British Industries. In 1919, Vickers acquired the Metropolitan Carriage Wagon Co, along with its controlling share in British Westinghouse, prompting the change in name to Metropolitan-Vickers Electrical Co Ltd. The American owned British Westinghouse had established its English operations at Trafford Park in 1899, and Metropolitan-Vickers Electrical Co Ltd continued on the same site from 8 September 1919. The company was initially known for its electricity generators, later diversifying into the manufacture of steam turbines, switchgear, transformers, electronics and railway traction equipment. The passing of the Electricity (Supply) Act in 1926 provided a boost to the company’s post-war fortunes, with the creation of the National Grid generating demand for the company's products. In 1928, Metropolitan-Vickers Electrical Co Ltd merged with its rival British Thomson Houston Co Ltd, retaining both names for trading purposes. The following year, on 4 January 1929, Associated Electrical Industries Ltd (AEI) acquired Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd. Again, both trading names were retained, and a fierce rivalry was established between the firms which the parent company was unable to control. In 1931, Sir Felix Pole joined Metropolitan-Vickers Electrical Co Ltd as its new chairman. He oversaw a period of expansion for the company leading into the Second World War. In 1939, seeking a more concise name for the company, the Board of Directors decided upon Metrovicks, which became interchangeable with the official company name of Metropolitan-Vickers Electrical Co Ltd. Under Sir Felix Pole's chairmanship, Metropolitan-Vickers developed new products for the aviation industry and during the war was one of the sites where Lancaster bombers were built. In 1941, the company developed the first British axial-flow jet engine, the Metrovick F.2. Following the Second World War, the company appointed Oliver Lyttelton as chairman, with the aim of increasing the efficiency and productivity of AEI. Despite his success in achieving this aim, Lyttelton was unable to resolve the commercial rivalry between Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd. During his second period as chairman, from 1954-1963, Lyttelton, now Lord Chandos, oversaw the development by Metropolitan-Vickers Electrical Co Ltd of the first commercial transistor computer, the Metrovick 950. Chandos also resolved to extinguish the competition and internal divisions between Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd, and both company names ceased to be used from 1 January 1960, with all subsidiaries going on to trade under the name of Associated Electrical Industries 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.

In 1886 R and W Hawthorn was amalgamated with the shipbuilding company of Andrew Leslie, thus becoming R and W Hawthorn Leslie & Co. 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.

In 1929 Vickers Ltd and Cammell Laird merged their rolling stock activities in a new company, the Metropolitan-Cammell Carriage, Wagon and Finance Company Ltd with Vickers and Cammell Laird each holding 50% of the shares of the new company. Following the Second World War, the company manufactured carriages for the railways of the world, including UK, USA, Canada, South Africa, Hong Kong, Singapore, Brazil, Jamaica, and Egypt. In addition, the company manufactured mineral wagons, diesel multiple units and locomotives. However, over this period of sustained high output, international industrial development together with reductions in home market demand as orders were fulfilled, led to the necessity to reduce capacity and in 1962 the Saltley Works were closed and eventually the whole enterprise was concentrated at the Midland Works offices at Leigh Road, Washwood Heath. In the 1970s Metro-Cammell specialised in the design and construction of rapid transit vehicles for customers such as London Underground, Tyne and Wear Metro, Hong Kong Mass Transit Corporation and the Kowloon Canton Railway Corporation. They also built Maglev vehicles for Birmingham Airport, diesel multiple units for BR and Mk IV coaches for BR. In May 1989 the Laird Group sold their transportation interests to GEC Alsthom and Metro-Cammell became part of the new Anglo-French Power Generation and Transportation Group. This led to involvement in the construction of the Eurostar trains for the Channel Tunnel project. The name Metro Cammell disappeared forever in 1998 when the owners floated the company under the name Alstom.

On 18th December 1966 E. E. Baguley and the Drewry Car Co Ltd amalgamated and the company named changed to Baguley-Drewry on the 1st June 1967. The company was located in Burton-on-Trent and manufactured a variety of railcars and railway locomotives between 1911 and 1984. The company was sold to Baguley (Engineers) Ltd on 1st December 1986.

The British Westinghouse Electric and Manufacturing Company Ltd was formed in 1889 by George Westinghouse as a manufacturing subsidiary of the American Westinghouse Electric and Manufacturing Company, of Pittsburgh, USA. Initially it was an agency for American exports, based in London. From 1902, the company was operating in newly-built offices and factory at Westinghouse Road, Trafford Park, Manchester. Products manufactured included gas engines, stationary steam engines, electric generators, transformers, switchgear, meters, motors, control gear, and arc lamps. During the First World War, British Westinghouse built some small petrol-electric locomotives for the War Department Light Railways. By 1916 British Westinghouse felt that the American ownership of its operations during World War One had been a hindrance, so a British holding company was created to obtain the American shares. In 1917 the Metropolitan Carriage, Wagon and Finance Co provided the capital for British Westinghouse to become independent of US control. Finally, in 1919 Vickers Ltd acquired the Metropolitan Carriage, Wagon and Finance Co and with it the British Westinghouse business. Vickers wished to be able to supplement their production of steel, ships, trains, and machinery with that of the associated electrical equipment. The company name changed to Metropolitan-Vickers Electrical Company on the 8th September 1919.

In 1883 Dick Kerr & Co Ltd was formed with John Kerr to take on the railway and tramway related activities built up by W B Dick & Co Ltd in Kilmarnock (Britannia Works). The company built steam locomotives to haul tramcars; and in 1887 constructed the first section of the cable tramway system in Edinburgh. In 1897, Dick, Kerr acquired disused premises, later known as East Works, in Preston for the manufacture of electric tramcars and rolling stock under the control of a subsidiary company, the Electric Railway and Tramway Carriage Works Limited (ER&TCW), later known as the United Electric Car Company Limited. The works developed a world market for electric urban tramway systems; however drive machinery for the vehicles had to be imported from the USA. The company provided complete electric coaches for the Waterloo & City Railway in 1899, and in 1904 equipped the first main line in Great Britain to be electrified between Liverpool and Southport. In 1900, the new works known as West Works were built by the English Electric Manufacturing company on the opposite side of Strand Road to the ER&TCW works, the rear boundary of the site being along the line of the original bank of the river Ribble. The factory was built for the manufacture of electric traction equipments, power station equipments and general engineering. In 1902, these works at Preston were taken over by Dick, Kerr & Co Limited. In 1917 the company acquired Preston based tram maker United Electric Car Company creating Britain's largest tram factory, and also a controlling interest in Willans and Robinson, Rugby. In 1918, Dick, Kerr and Co Ltd became one of the founding companies of the English Electric Co Ltd.

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.

GEC Transportation Projects Ltd., (GEC-TPL) was established in 1974 and was based at St Albans and Borehamwood, Hertfordshire. It specialised in the design, execution and management of major railway and mass transit electrification projects around the world. In 1981 GEC-TPL was transferred to Trafford Park in Manchester took over residual responsibility for vehicle design from GEC Traction, e.g. British Railways Class 91s and locomotive equipment design, e.g., British Railways Class 90s. GEC-TPL project managed 406 track kilometres of electrification in Taiwan in 1984. It involved the design, supply and installation of equipment including catenary, substations, telecommunications, locomotives and multiple units. The company also supplied the 134, 3-car trains and project managed the equipment of Lines 3 and 4 of Seoul Metropolitan Subway Corporation. Closer to home, GEC-TPL was the project management company for Phase 1 of the Docklands Light Railway and the Manchester ‘Metrolink’ and supplied the initial vehicles for both systems. In 1987, GEC-TPL contracted to supply the body mounted power equipment for the initial build of Trans Manche Super Trains, later known as ‘Eurostars’, the bar car mechanical parts for which were supplied by its long term partner Metropolitan Cammell which later became part of GEC-TPL in 1989. In 1989, GEC Transportation Projects Ltd became part of the joint company, GEC Alsthom Transportation Projects Ltd., when GEC and Alsthom of France, part of Compagnie Générale d’Electricité (CGE) formed GEC Alsthom. The combined company acquired Metropolitan Cammell at this time. (Alsthom’s name had earlier been derived from ‘Alsace Thomson-Houston’, thereby revealing its earlier parentage from Thomson-Houston of America, as also had the British Thomson-Houston Co., of Rugby, another GEC constituent). In 1998 the company formally changed its name to ALSTOM.

The General Electric Company (GEC) was created as the General Electric Apparatus Company in 1886 by Hugo Hirst and Gustav Byng from a small electrical business established in London by Byng (Gustav Binswanger and Company, using Byng's original name). In 1887 GEC published the first electrical catalogue of its kind. The following year the company acquired its first factory in Manchester where telephones, electric bells, ceiling roses and switches were manufactured. In 1889, the General Electric Co. Ltd. was formed as a private limited company and moved to larger premises at 71, Queen Victoria Street. Now known also as G.E.C., the company was expanding rapidly, opening new branches and factories. Initially manufacture was focussed on electric bells and light fittings, but this expanded to a wide range of electrical equipment - resulting in the firm's slogan 'Everything Electrical'. In 1893, GEC decided to invest in lamp manufacture. The resulting company, (to become Osram in 1909), was to lead the way in lamp design and the burgeoning demand for electric lighting was to make GEC's fortune. In 1900, GEC was incorporated as a public limited company, The General Electric Company (1900) Ltd, (the '1900' was dropped three years later). In 1902, GEC's first purpose-built factory, the Witton Engineering Works was opened near Birmingham which designed and manufactured electrical equipment and machines. Rapidly growing private and commercial use of electricity ensured buoyant demand and the company expanded both at home and overseas, with the establishment of agencies in Europe, Japan, Australia, South Africa and India and a substantial export trade to South America. The outbreak of the First World War transformed GEC into a major player in the electrical industry with profits to match. The company was heavily involved in the war effort, with products such as radios, signalling lamps and arc-lamp carbons. Between the wars, GEC expanded to become an international corporation and a national institution. The take-over of Fraser and Chalmers in 1918 took GEC into heavy engineering and consolidated their claim to supply 'Everything Electrical'. Other major factories included Osram Lamps at Hammersmith and the telephone works in Coventry. During the 1920s, the company was heavily involved in the creation of the UK national grid. In addition, the opening of the new purpose built company headquarters in Kingsway, London in 1921, and the pioneering industrial research laboratories at Wembley in 1923, were symbolic of the continuing expansion of both GEC and the electrical industry. The company took over several companies in the Birmingham area and elsewhere. After being a minor player in tram equipment, the company entered the heavy rail electric traction market in the 1920’s and 30’s. During the Second World War, GEC was a major supplier to the military of electrical and engineering products. Significant contributions to the war effort included the development of the cavity magnetron for radar, advances in communications technology and the on-going mass production of lamps and lighting equipment. After the war the company continued in the full range of electrical equipment from electronics to atomic power stations, but was not very profitable. In 1961, after a failed takeover bid from the English Electric Company, GEC took over Radio and Allied Industries, a small but very profitable television set manufacturer. Michael Sobell and Arnold Weinstock from this company became GEC directors with a substantial shareholding. Weinstock became managing director in 1963 and undertook drastic changes to make the company more profitable. The rail traction operations were closed and the heavy electrical/ power station businesses were sold to Parsons. A number of ex GEC employees were recruited by Associated Electrical Industries (AEI). A hostile takeover bid was made for AEI in 1967 and the relative profitability/share prices enabled GEC to take over the much larger AEI. In 1968 English Electric agreed to merge with GEC. Further takeovers and mergers made the company one of the largest private employers in the UK. In 1989, Arnold Weinstock agreed a merger between the power and transport businesses of GEC and those of Alsthom of France, part of Compagnie Générale d’Electricité (CGE) to form GEC Alsthom. While Weinstock was in charge the UK arm, the company continued to prosper, but after his death of his son in 1996 he was asked to retire and most of the company’s operations were transferred to France, or were sold off. Small sales and service operations remain for some of the products. Many of the factories have been demolished, with only Stafford continuing on a moderate scale.

General Electric Company, USA (GE), was incorporated on 15 April 1892 as a result of a merger between competing companies Edison General Electric and the Thomson-Houston Company, based in Schenectady, New York. In 1896 GE established a subsidiary company called British Thomson-Houston (BTH) for the exploitation of its products in the United Kingdom. In the railway field GE produced electric propulsion equipment, electric locomotives and diesel-electric locomotives from the 1930s and also supplied electrical equipment for PCC streetcars. In 1989 GE agreed to combine its European business interests in appliances, medical systems, electrical distribution, and power systems with the formerly unrelated British corporation General Electric Company. GE’s business groups in the early 21st century were in the areas of commercial finance; consumer finance; infrastructure (including diesel locomotives, jet engines, water treatment systems, and energy delivery systems such as power grids); consumer and industrial technologies (including appliances and lighting products); health care (including diagnostic and imaging products); and media and entertainment through NBC Universal. In 2009 it was announced that GE had agreed to sell a majority stake in NBC Universal to Comcast. In June 2014 GE bought Alstom’s Power and Grid businesses.

The Coal Industry Nationalisation Act 1946 provided for the complete nationalisation of the coal industry and on 12 July 1946 established the National Coal Board (NCB). This body, appointed on 15 July 1946, was made solely responsible for managing the industry and running it on business lines, except that the Minister of Fuel and Power, after consulting with the board, might give it directions of a general character. The minister appointed the members of the board, numbering nine in 1946, raised to a maximum of eleven of which eight should be full-time in 1949 and to a maximum of fourteen in 1973, and he presented the NCB's reports to Parliament. In October 1969 these general powers passed to the Ministry of Technology, in October 1970 to the Department of Trade and Industry, and in January 1974 to the Department of Energy. The eight departments of the National Coal Board headquarters - Production, Marketing, Finance, Labour Relations, Manpower and Welfare, Scientific, Legal and Secretary's - made up the National Board and formed the top tier of a four tier system. At the lowest level were the coalfields (each colliery had its own manager) which were divided into 48 geographical areas under the control of an area manager. The areas were grouped into 8 geographical divisions under a divisional board which reported to the National Board. On the vesting date, 1 January 1947, the productive assets of the 800 or more private colliery undertakings and the service contracts of their employees were transferred to the National Coal Board, as were the coal deposits and other assets of the Coal Commission and the functions and staff of the district selling schemes. Subsequently the board acquired other responsibilities, notably that for the coal survey from the Department of Scientific and Industrial Research in August 1947, and that for miners' hostels from the Ministry of Labour and National Service in the same year. In 1951 it took over some of the functions of the Miners' Welfare Commission, and in April 1952 it acquired responsibility for opencast coal mining from the Ministry of Fuel and Power. In 1973 it formed two holding companies, NCB (Coal Products) Ltd. and NCB (Ancillaries) Ltd. to handle two major aspects of its work not directly related to deep and opencast mining. The Coal Industry Act 1977 gave the board new powers in respect of the acquisition, treatment and sale of petroleum and of working minerals other than coal or petroleum which were discovered in the course of prospecting for or working coal and petroleum. The NCB was headed by a chairman and deputy chairman; each of the other members took charge of an executive department or research establishment. The main functions of the board as a whole were to decide and set objectives for the industry, to lay down policy directives and the limits within which management must work, to hold management to account and to provide for the future by means of research and development, and the recruitment and training of staff. It was also responsible for promoting the safety, health and welfare of employees. Many of these functions were exercised at the area and colliery level, a chain of command which replaced the previous five-tier system in 1967. The board itself continued to settle national policy, conduct national negotiations, obtain capital and provide common services such as scientific research. Before 1967 the divisional boards also exercised wide discretion in the forming of policy and applying it at area and colliery level. The headquarters departments advised the board on general policy and objectives, provided information and executed policy, and they also operated certain national services, including central workshops and the rescue service; and regional services in non-coalfield areas. On 1 January 1987, the NCB became the British Coal Corporation, which was wound up in 1997.

Construction commenced from Water Street, Freetown in 1896 of the Sierra Leone Government Railway (SLR) with the first section of railway to Wellington, seven miles away opening in March 1897. Later line openings included Waterloo in April 1898; Songo in 1899; Rotifunk in 1900; Bo in 1903 and Baiima in 1905. In 1907 the final destination of Pendembu was reached at 227 from Water Street and there the main line ended. A branch was built between 1914 and 1916 from Bauya Junction to Makeni and Kamabai with a length of 104 miles bring the total route mileage to 331 miles. A further line of 5 ½ miles was built in 1903 known as the Mountain Railway, connected by rail from the docks and Water Street station, this climbed from a station at Cotton tree, Freetown to Hill Station, at 748 feet above sea level. This line allowed people to live in the more rarefied air above Freetown, however the line wass closed in 1929 as surveys in the late 1920s had already shown it to be losing money against road competition. The railways assumed increased importance during the Second World War moving food and resources from inland to the coast and supporting fighting in North Africa with fighter aircraft transported in kit form to Pendembu where they were assembled and flown to Egypt. In the 1950s the equipment of the railway was renewed with the introduction of diesel locomotives and new freight wagons. Increased road traffic and changes in government policy in the 1960s saw a decline in railway traffic, so the railway diversified by opening a new branch to serve a bauxite mine and converting to a wider gauge to fit in with much of the rest of Africa. In 1968 the Makeni branch closed followed by the section between Kenema and Pendembu in 1971 and the line cut back to Bo in 1973. The last official passenger train ran on the line on 17th November 1974. Trains continued to run on a sporadic basis into mid-1975 but the lifting of the track and its sale to a Lebanese scrap merchant in August 1975 put an end to this.

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.

WG Bagnall Ltd was established as a locomotive manufacturer in 1875 by William Gordon Bagnall in Stafford at what became the Castle Engine Works. Bagnalls first locomotive was produced in 1876, the company going on to produce machines for collieries and overseas plantations. The majority of the products that were manufactured were small four and six-coupled steam locomotives for industrial use, the company were noted for building steam and diesel locomotives in standard and narrow gauges. In 1891 Ernest Edwin Baguley joined the company, he left in 1902 to start his own business. Bagnalls introduced several novel type of locomotive valve gear including the Bagnall-Price and the Baguley. They also used marine (circular) fireboxes on narrow gauge engines, a design that was cheap but needed a different firing technique. Some of the designs of Kerr, Stuart and Co were brought to Bagnalls when they employed William Sydney Edwards, the Chief Draughtsman of Kerr Stuart and Co. Examples of such locomotives can be seen on the Sittingbourne and Kemsley Light Railway. In addition to locomotives, Bagnalls constructed rolling stock and trackwork enabling the complete equipping of light railways. In 1933 Bagnalls entered into an agreement with Deutz of Germany to manufacture their locomotives under licence using engines imported from Germany. In 1948 WG Bagnall Ltd was sold to the Bridge and Steelwork Company, Heenan and Froude, whose owner also owned The Brush Electrical Engineering Co Ltd of Loughborough and in 1951, Bagnalls formed an association with Brush to create Brush-Bagnall Traction Ltd. This association only lasted two years. Heenan and Froude sold Bagnalls to W H Dorman & Co in 1959 in exchange for Dorman ‘A’ shares.

The firm began as a partnership between Peter Willans and Mark Robinson in 1880 at Thames Ditton in Surrey, manufacturing high-speed steam engines using Willans’ design for river launches. Willans invented the central-valve steam engine that was crucial to the firm’s initial success but he died in 1892 after an accident, so didn’t see the company expansion that led to the move to Rugby in 1897. By the time of Willans’ death the company engines were driving almost 70% of the turbines generating Britain’s overall electricity output and demand was coming in from overseas. Despite this success and pioneering developments in steam electric locomotives, motorcar parts production, boiler manufacture and steam turbines, the firm struggled with controlling its finances. This led to it being taken over by Dick, Kerr and Company Ltd in 1917, which then became part of English Electric a year later. This saw the name of the site changed to the Willans Works. English Electric came under the ownership of GEC in 1968, which also ran British Thomson-Houston, another power generation company that was also in Rugby. The Willans site eventually became part of the thermal power division for Alstom, but this activity has now been transferred to France.
