London OvergroundLondon Overground (also known simply as the Overground) is a suburban rail network serving London and its environs. Established in 2007 to take over Silverlink Metro routes, it now serves a large part of Greater London as well as the home county of Hertfordshire, with 113 stations on nine different routes. The Overground forms part of the United Kingdom's National Rail network but it is under the concession control and branding of Transport for London (TfL). Operation has been contracted to Arriva Rail London since 2016.
Tube mapThe Tube map (sometimes called the London Underground map or diagram) is a schematic transport map of the lines, stations and services of the London Underground, known colloquially as "the Tube", hence the map's name. The first schematic Tube map was designed by Harry Beck in 1931. Since then, it has been expanded to include more of London's public transport systems, including the Docklands Light Railway, London Overground, the Elizabeth line, Tramlink, the London Cable Car and Thameslink.
ThameslinkThameslink is a 24-hour main-line route in the British railway system, running from , , , and via central London to Sutton, , , Rainham, , and . The network opened as a through service in 1988, with severe overcrowding by 1998, carrying more than 28,000 passengers in the morning peak. All the services are currently operated by Govia Thameslink Railway. The Thameslink Programme was a major £5.5 billion scheme to increase capacity on the central London section by accommodating more frequent and longer trains, and providing additional routes and destinations.
Rapid transitRapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport that is generally built in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways, usually electric, that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles. They are often grade-separated in tunnels or on elevated railways.

It is on the London, Tilbury and Southend line (LTSR), down the line from London Fenchurch Street; it is the eastern terminus of the District line on the London Underground; and it is the eastern terminus of the Romford to Upminster Line on the London Overground network. Upminster is the easternmost station on the London Underground network as well as the easternmost National Rail station in London.
Metropolitan lineThe Metropolitan line, colloquially known as the Met, is a London Underground line between in the City of London and and in Buckinghamshire, with branches to in Hertfordshire and in Hillingdon. Printed in magenta on the tube map, the line is in length and serves 34 stations (13 of which are step free to platform). Between Aldgate and , the track is mostly in shallow "cut and cover" tunnels, apart from short sections at and Farringdon stations. The rest of the line is above ground, with a loading gauge of a similar size to those on main lines.
City and South London RailwayThe City and South London Railway (C&SLR) was the first successful deep-level underground "tube" railway in the world, and the first major railway to use electric traction. The railway was originally intended for cable-hauled trains, but owing to the bankruptcy of the cable contractor during construction, a system of electric traction using electric locomotives—an experimental technology at the time—was chosen instead. When opened in 1890, the line had six stations and ran for in a pair of tunnels between the City of London and Stockwell, passing under the River Thames.
Morden tube stationMorden is a London Underground station in Morden in the London Borough of Merton. The station is the southern terminus for the Northern line and is the most southerly station on the Underground network, despite being on the Northern Line. The next station towards north is . The station is located on London Road (A24), and is in Travelcard Zone 4. Nearby are Morden Hall Park and Morden Park.

East London lineThe East London line is part of the London Overground, running north to south through the East, Docklands and South areas of London. It was previously a line of the London Underground. Built in 1869 by the East London Railway Company, which reused the Thames Tunnel intended for horse-drawn carriages, the line became part of the London Underground network in 1933. After nearly 75 years as part of that network, it closed on 22 December 2007 for an extensive refurbishment and expansion, reopening as part of the Overground network in April 2010.
