London Overground in the context of "East London Railway"

London has an extensive and developed transport network which includes both public and private services. Journeys made on its integrated transport network account for 37% of London's journeys while private services accounted for 36% of journeys, walking 24% and cycling 2%, according to numbers from 2017. London's public transport network serves as the central hub for the United Kingdom in rail, air and road transport.

Public transport services are dominated by the city's executive agency for transport, Transport for London (TfL). TfL controls the majority of public transport, including the Underground, Buses, Tramlink, the Docklands Light Railway, London River Services, Elizabeth line and the London Overground.

The Réseau Express Régional (French pronunciation: [ʁezo ɛkspʁɛs ʁeʒjɔnal]; English: Regional Express Network), commonly abbreviated RER (pronounced [ɛʁəɛʁ]), is a hybrid commuter rail and rapid transit system serving the city centre of Paris and its suburbs. It acts as a combined city centre underground rail system and suburbs-to-city-centre commuter rail, similar to the S-Bahn in Germany, Austria and Switzerland, S-train in Copenhagen, the Pendeltåg in Sweden, the Overground and Elizabeth Line in London, S Lines in Milan, plus many other commuter rail networks around the world.

Conceived of as a métropolitain express ('express metro') during the mid-1930s, the scheme was revived in the 1950s and construction began in the early 1960s. The RER was not fully conceptualised until the completion of the Schéma directeur d'aménagement et d'urbanisme (rough translation: 'master plan for urban development') in 1965. The RER network, which initially comprised two lines, was formally inaugurated on 8 December 1977 in a ceremony that was attended by President Valéry Giscard d'Estaing. A second phase of construction commenced at the end of the 1970s which saw additional lines constructed along with extensions to the original two. The RER is operated partly by RATP, the authority that operates most of the public transport in Paris, and partly by the SNCF, France's national rail operator.

Transport for London (TfL) is a local government body responsible for most of the transport network in London, United Kingdom.

TfL is the successor organisation of the London Passenger Transport Board, which was established in 1933, and several other bodies in the intervening years. Since the current organisation's creation in 2000 as part of the Greater London Authority (GLA), TfL has been responsible for operating multiple urban rail networks, including the London Underground and Docklands Light Railway, as well as London's buses, taxis, principal road routes, cycling provision, trams, and river services. It does not control all National Rail services in London, although it is responsible for London Overground and Elizabeth line services. The underlying services are provided by a mixture of wholly owned subsidiary companies (principally London Underground), by private-sector franchisees (the remaining rail services, trams and most buses) and by licencees (some buses, taxis and river services). Fares are controlled by TfL, rail services fares calculated using numbered zones across the capital.

Clapham Junction (/ˈklæpəm ˈdʒʌŋkʃən/) is a major railway station near St John's Hill in south-west Battersea, in the London Borough of Wandsworth, England. It lies 2 miles 57 chains (2.71 mi; 4.37 km) from London Victoria and 3 miles 74 chains (3.93 mi; 6.32 km) from London Waterloo. Despite its name, Clapham Junction is not in Clapham, a district 1 mile (1.6 km) to the south-east.

A major transport hub, Clapham Junction station is on both the South West Main Line and Brighton Main Line, as well as numerous other routes and branch lines which pass through or diverge from the main lines at this station. It serves as a southern terminus of both the Mildmay and Windrush lines of the London Overground.

Stratford is a major multi-level interchange station serving the town of Stratford and the mixed-use development known as Stratford City, in the London Borough of Newham, East London for London Underground, London Overground, Docklands Light Railway (DLR) and Elizabeth line services. National Rail services also operate on the West Anglia Main Line and the Great Eastern Main Line, 4 miles 3 chains (6.5 km) from Liverpool Street.

It is the seventh busiest railway station in Britain, the second busiest station in London outside the London station group, and is the busiest station on the London Underground network outside London fare zone 1.

Wembley Central is an interchange station in Wembley, north-west London. It is situated on the east-west High Road and is near to both Wembley Stadium and Wembley Arena. The station, which is in London fare zone 4, provides Bakerloo line services of the London Underground, Lioness line services of the London Overground, and National Rail services operated by Southern on the West Coast Main Line.

The North London line is a railway line which passes through the inner suburbs of London, England between Richmond in the south-west and Stratford in the east, avoiding central London. Its route is a rough semicircle.

Although much of it originated as part of the North London Railway, the current route is the result of a series of amalgamations, closures and reopenings, and has a mix of third-rail and overhead electrical power supply. It remains heavily used by freight services in addition to the Mildmay line passenger service on the London Overground. Between Richmond and Gunnersbury, London Underground's District line shares tracks with the Mildmay line; the entire route is owned and maintained by Network Rail.

Euston railway station (/ˈjuːstən/ YOO-stən; or London Euston) is a major central London railway terminus and connected London Underground station managed by Network Rail in the London Borough of Camden. It is the southern terminus of the West Coast Main Line, the UK's busiest inter-city railway. Euston is the tenth-busiest station in Britain and the country's busiest inter-city passenger terminal, being the gateway from London to the West Midlands, North West England, North Wales and Scotland.

Intercity express passenger services to the major cities of Birmingham, Manchester, Liverpool, Glasgow and Edinburgh, and through services to Holyhead for connecting ferries to Dublin are operated by Avanti West Coast. Overnight sleeper services to Scotland are provided by the Caledonian Sleeper. London Northwestern Railway provide commuter and regional services to the West Midlands, whilst the Lioness line of the London Overground provides local suburban services in the London area via the Watford DC Line which runs parallel to the West Coast Main Line as far as Watford Junction. Euston tube station is connected to the main concourse and Euston Square tube station is nearby. King's Cross and St Pancras railway stations are about 1⁄2 mile (800 metres) east along Euston Road.

Fare zone 1 is the central zone of Transport for London's zonal fare system used by the London Underground, London Overground, Docklands Light Railway and National Rail. For most tickets, travel through Zone 1 is more expensive than journeys of similar length not crossing this zone. The zone contains all the central London districts, most of the major tourist attractions, the major rail terminals, the City of London, and the West End. It is about 6 miles (10 km) from west to east and 4 miles (6 km) from north to south, approximately 17 square miles (45 km).
