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.

In 1900 the British Westinghouse Electrical & Manufacturing Co Ltd bought land in Trafford Park and built a factory which went into production in 1902 for the manufacture of mechanical and electrical equipment for the generation, transmission and use of electricity. In 1919, Trafford Park Works became owned by British Westinghouse’s successor, Metropolitan-Vickers Electrical Company (MV). The main shops, in common with factory construction throughout Trafford Park, were single floor type, with bays 1,000 feet in length, and had direct railway communication with the docks and trunk systems of the country. The main office block was a copy of the Westinghouse building in Pittsburgh, USA and the factory was to the American design and used imported steelwork for construction. Products manufactured at the Works 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. In 1928 the Works were taken over by Associated Electrical Industries (AEI), which merged Metropolitan-Vickers and British Thomson-Houston, though these two companies continued their own trading names. Traction design and manufacture was always a minority of the workload at Trafford Park with the largest operations generally turbine manufacture. Very few vehicles were built there, and traction machines (i.e. motors, inductors and generators) were largely built in other places – notably at Sheffield or Rugby. Trafford Park traction manufacture was largely that of assembling control gear – contactors, switches, drivers’ controllers, camshaft controllers, relays etc. and building these into frames or equipment boxes for installation in vehicles made elsewhere. An important part of the Trafford Park Works site was the general switchgear operation, mainly for generation or distribution installations. The on-site Switchgear Testing Company was a “testing house” for these products and contributed to testing and development of traction circuit breakers and switchgear. During the Second World War MV acting for the Ministry of Aircraft Production produced more than a thousand Lancaster Bombers in the adjacent Mosley Road building. The company also manufactured war munitions and in the laboratories developed what became known as Radar. In 1959 the newly formed AEI Traction Division established its headquarters at Trafford Park, with a product range that included electric and diesel-electric locomotives; electrical equipment for tram-cars, trolley buses and trolley mining locomotives and traction motors. AEI was taken over by the General Electric Company (GEC) in 1967 whose Witton Works closed in 1969, with the design office and traction manufacture transferred to Trafford Park, as a result of the GEC reorganisation and mergers. GEC Traction Ltd took over the Works in 1972. In 1990 the former Low Voltage Switchgear site at Trafford Park (West Works) was renovated to be the new manufacturing facility for GEC Alsthom Traction, with an electronics workshop, machine shop and plating baths, and an assembly shop for switchgear, equipment cases and power modules. This building was vacated in 1998 when power modules and switchgear was moved to Tarbes in south west France. The Works housed the administrative, commercial and accounting functions, the majority of the design departments and the development section with its associated workshops and laboratories. The manufacturing area was devoted primarily to the production of components of traction control and railway signalling equipment. 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, with the eventual closing of all activities at Trafford Park in 1998. The iconic original Westinghouse building was demolished and the site is now (2015) largely devoted to container handling and logistics operations.

In 1861 Sir Edward Lumb, a British entrepreneur, requested a concession from the Legislature of the Province of Buenos Aires to build a railway line from Constitucion to Chascomus, 120km away from Buenos Aires, which was granted on June 12th 1862 by President Bartolome Mitre. In 1863, with the support of London shareholders Thomas Duguid, the Fair family, British consul Frank Parish (later Southern’s chairman), and bankers Baring and David Robertson, Buenos Aires Great Southern Railway Ltd. was established. The first general manager of the company was Edward Banfield, the Buenos Aires suburban station of Banfield was named after him when it opened in 1873. Buenos Aires Great Southern Railway had its company headquarters in London, and operated workshops and rolling stock depots in Barracas. The main stations of the Buenos Aires Great Southern Railway are Constitucion, Barracas al Sud, Jeppener, Chascomus, Barracas al Norte, Las Flores, Azul, Dolores and Banfield. In 1877 Buenos Aires Great Southern Railway built a new warehouse in Constitucion station for freight trains and a freight station at Sola in Buenos Aires where repair shops operated for 15 years. By 1884 Buenos Aires Great Southern Railway was the largest in Argentina, with 1,025km of track. In 1901 new workshops were built at Remedios de Escalada, 11km from Constitucion station, being the largest workshop in South America, employing 2700. In 1925, the company took over Bahia Blanca and North Western Railway from Buenos Aires and Pacific Railway Company. By 1930 Buenos Aires Great Southern Railway Company had 8000 km of track, 504 stations, 857 locomotives, 955 carriages, 16,602 coaches and 30,000 employees. The company continued to function until 1948, when President Juan Peron nationalised the Argentine Railway, creating six state owned railway networks. Buenos Aires Great Southern Railway was incorporated into the Ferrocarril General Roca network.
