The New South Wales Government Railways (NSWGR) were operated by the New South Wales Government from 1855 who administered all the railway lines in the New South Wales area from headquarters in Sydney. The lines ranged from Brisbane (Queensland) and Broken Hill (South Australian Frontier) to Albury (Victorian Frontier). Between 1855 and 1932 the operation of NSWGR changed many times, altering between a Chief Commissioner with sole authority and groups of commissioners who shared responsibility. After the 1932 amendment of the Railways Act by the Transport (Division of Factions) Act, NSWGR was replaced by the Department of Railways New South Wales.

The London and South Western Railway Company (LSWR) opened their first line in stages in from London to Southampton in 1838 under the name London and Southampton Railway Company. A year later the company name was changed to the LSWR. By the early 1900s, the line had been extended and ran from London to Plymouth via Yeovil, Exeter and Southampton. Some of the branch lines of the LSWR, further into Southern counties, were in direct competition with the Great Western Railway Company and others were worked in partnership with other railway companies such as the Somerset and Dorset Joint Railway. Nine Elms in London was the main depot of the LSWR, until Waterloo Station was opened by the company in 1848. Nine Elms became the goods depot for the London and South Western Railway Company and Waterloo became one of the biggest passenger stations in the country. The main LSWR engineering works was transferred from Nine Elms to Eastleigh by 1909. Sir Herbert Walker was General Manager of the London and South Western Railway Company from 1912, when he instituted the third-rail electrification programme, and was appointed General Manager of the Southern Railway Company in 1923, until his retirement in 1937. There were a number of notable engineers attached to the LSWR including John Viret Gooch, brother of Sir Daniel Gooch who was Locomotive Superintendent from 1841 to 1850. Dugald Drummond was the Chief Mechanical Engineer from 1895 to 1912; he facilitated moving the Works from Nine Elms to Eastleigh and their subsequent expansion and modernisation. Alfred Szlumper, appointed Chief Engineer in 1914 was key to the expansion and redesign of Waterloo Station, completed by 1922 The LSWR began electrification of its suburban lines from Waterloo in 1913. The first section was opened in 1915, and almost all the other planned routes were opened before the First World War curtailed the project. The London and South Western Railway Company was very prominent in handling all types of traffic during the First World War, due to it’s position serving London and the ports on the South Coast. The LSWR also had an ocean-going port at Southampton, which was a growing rival to Liverpool and Glasgow for transatlantic travel. The purchase of Southampton docks by the LSWR in 1892, alongside their expansion and modernisation, was organised by Sir Charles Scotter, the General Manager from 1885 to 1898. Scotter then became Chairmen of the Company from 1904 to 1910. The LSWR also ran steamer services from Southampton to the Channel Islands and France. In 1923, the LSWR was grouped into the Southern Railway Company by the Railways Act of 1921.

The Japanese Government Railway (JGR) was operated by the imperial government from 1872. In 1949, JGR was reorganised to become a state-owned public corporation named the Japanese National Railways.

Railway in Brazil, opened on 14 July 1884. The railway, also known as the Rio Verde Railway, was British owned and constructed, running from Cruzeiro to as far as Três Corações do Rio Verde. The line played an important role in the growth of Brazil's coffee economy. It was taken over by the Federal Government in 1901.

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.

The Central Chubut Railway was a British-owned company that built and operated a railway line in the Argentine province of Chubut in the Patagonia region at the end of the 19th century.

The Midland Railway was formed in 1844 from the merger of the Midland Counties Railway, the North Midland Railway and Birmingham and Derby Junction Railway wit its headquarters in Derby. It expanded its operational territory by acquisition (e.g. railways in the Erewash valley, to Sheffield, serving the Leicestershire coalfields and the route from Birmingham to Bristol), and by construction of new railways and extensions to existing lines, including lines to Peterborough and Lincoln, towards Manchester and, most notably the Settle to Carlisle route. It expanded into the South Wales coalfields, and acquired railways not connected to its main routes: the London, Tilbury and Southend Railway and, in Ireland, the Belfast and Northern Counties Railways. Much of this activity was driven by competition with its geographical rivals, the London and North Western Railway to the west and the Great Northern Railway to the east. Where its interests were better served by co-operation, it tried to reach agreements with those same companies to share routes and traffic receipts. The most famous of these is the Euston Square Confederation, an agreement between the Midland Railway, the London and North Western Railway and the Manchester, Sheffield and Lincolnshire Railway. Other such arrangements were the Cheshire Lines Committee and the right to run over the Great Northern Railway into King’s Cross station. The arrangements for through running and sharing of London termini with its competitors proved unsatisfactory. As a consequence the Midland Railway eventually built its own connection to London. The line ran from Bedford on the Midland’s existing Leicester to Hitchin line, to a terminus at St Pancras. It was opened in 1868. The Midland Railway was a partner in several joint railways e.g. the Somerset and Dorset Joint Railway (with the London and South Western Railway), and the Midland and Great Northern Joint Railway (the Great Northern Railway). The Midland Railway came under the control of the Railway Executive during the First World War and ended its independent existence in 1923 under Grouping when it was merged with, amongst other railway companies, its great rival the London and North Western Railway to form the London, Midland and Scottish Railway Company.
