At , it is the longest river entirely in England and the second longest in the United Kingdom, after the River Severn.

The Thames drains the whole of Greater London. , The West India Docks are a series of three docks on the Isle of Dogs in London, England the first of which opened in 1802.

Generally, tram stops share most characteristics of bus stops, but because trams operate on rails, they often include railway platforms, especially if stepless entries are provided for accessibility. However, trams may also be used with bus stop type flags and with mid-street pavements as platforms, in street running mode., The London and North Eastern Railway (LNER) was the second largest of the "Big Four" railway companies created by the Railways Act 1921 in Britain. It operated from 1 January 1923 until nationalisation on 1 January 1948.

Dual side platform stations, one for each direction of travel, is the basic station design used for double track railway lines (as opposed to, for instance, the island platform where a single platform lies between the tracks). Side platforms may result in a wider overall footprint for the station compared to an island platform where a single width of platform can be shared by riders using either track., The Mayor of London is an elected politician who, along with the London Assembly of 25 members, is accountable for the strategic government of Greater London. The current mayor is Sadiq Khan, who took up office on 9 May 2016.

The company was grouped into the London and North Eastern Railway in 1923., Minories (not ) is the name of a former civil parish, also known as Minories Holy Trinity, and a street in the City of London, close to the Tower of London., Middlesex (abbreviation: Middx) was a county in southeast England that is now mostly part of Greater London, with small sections in neighbouring counties. It was established in the Anglo-Saxon system from the territory of the Middle Saxons, and existed as an official unit until 1965. The historic county included land stretching north of the River Thames from east to west of the City of London with the rivers Colne and Lea and a ridge of hills as the other boundaries. The largely low-lying county, dominated by clay in its north and alluvium on gravel in its south, was the second smallest by area in 1831., The London Assembly is an elected body, part of the Greater London Authority, that scrutinises the activities of the Mayor of London and has the power, with a two-thirds majority, to amend the Mayor's annual budget and to reject the Mayor's draft statutory strategies. The assembly was established in 2000 and meets at City Hall on the South Bank of the River Thames, close to Tower Bridge. The assembly is also able to investigate other issues of importance to Londoners (transport, environmental matters, etc.), publish its findings and recommendations, and make proposals to the Mayor., Stepney is a district of the London Borough of Tower Hamlets in London's East End that grew out of a medieval village around St Dunstan's church and the 15th century ribbon development of Mile End Road. The area built up rapidly in the 19th century, mainly to accommodate immigrant workers and displaced London poor, and developed a reputation for poverty, overcrowding, violence and political dissent. It was severely damaged during the Blitz, with over a third of housing totally destroyed; and then, in the 1960s, slum clearance and development replaced most residential streets with tower blocks and modern housing estates. Some Georgian architecture and Victorian era terraced housing survive in patches: for example Arbour Square, the eastern side of Stepney Green, and the streets around Matlock Street., Londinium was a settlement established on the current site of the City of London around  43. Its bridge over the River Thames turned the city into a road nexus and major port, serving as a major commercial centre in Roman Britain until its abandonment during the 5th century., A meander, in general, is a bend in a sinuous watercourse or river. A meander forms when moving water in a stream erodes the outer banks and widens its valley, and the inner part of the river has less energy and deposits silt. A stream of any volume may assume a "meandering" course, alternately eroding sediments from the outside of a bend and depositing them on the inside. The result is a "snaking" pattern as the stream meanders back and forth across its down-valley axis. When a meander gets cut off from the main stream, an oxbow lake forms. Over time meanders migrate downstream, sometimes in such a short time as to create civil engineering problems for local municipalities attempting to maintain stable roads and bridges., Surrey is a county in the south east of England and also one of the home counties bordering Greater London. Surrey shares borders with Kent to the east, East Sussex to the south-east, West Sussex to the south, Hampshire to the west and south-west and Berkshire to the north-west. The county town is Guildford. Surrey County Council sits extraterritorially at Kingston upon Thames, administered as part of Greater London since 1965. With a resident population of 1.1 million, Surrey is the most densely populated and third most populated county in the South East region, after Kent and Hampshire., An island platform (also center platform, centre platform) is a station layout arrangement where a single platform is positioned between two tracks within a railway station, tram stop or transitway interchange. Island platforms are popular on twin-track routes and can provide for services in both directions from a single platform requiring only one set of supporting services (lifts, escalators, toilets, ticket offices, kiosks). They are also useful within larger stations where local and express services for the same direction of travel can be provided from opposite sides of the same platform thereby simplifying transfers between the two. An alternative arrangement is to position side platforms on either side of the tracks., The Isle of Dogs is an area in the East End of London that is bounded on three sides (east, south and west) by one of the largest meanders in the River Thames. The northern boundary has never been clearly or consistently defined (the name Isle of Dogs had no official status until 1987, with the creation of the Isle of Dogs Neighbourhood by Tower Hamlets Borough Council), but many accept it to be the (former) line of the West India South Dock., Kent is a county in South East England and one of the home counties. It borders Greater London to the north west, Surrey to the west, East Sussex to the south west, and Essex across the Thames Estuary to the north. The county town is Maidstone. , The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe.

With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan.

Today the site is occupied by a BT telecommunications building ., London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly., Originally called the Commercial Railway, the London and Blackwall Railway (L&BR) in east London, England ran from Minories to Blackwall via Stepney, with a branch line to the Isle of Dogs, connecting central London to many of London's docks. It was operational from 1840 until 1926 (for passengers) and 1968 (for goods), closing after the decline of inner London's docks. Much of its infrastructure was reused as part of the Docklands Light Railway. The L&BR was leased by the Great Eastern Railway in 1866, but remained independent until absorbed into the London and North Eastern Railway at the 1923 Grouping., Canary Wharf is a major business district located in Tower Hamlets, East London.
