Isle of DogsThe Isle of Dogs is a large peninsula bounded on three sides by a large meander in the River Thames in East London, England, which includes the Cubitt Town, Millwall and Canary Wharf districts. The area was historically part of the Manor, Hamlet, Parish and, for a time, the wider borough of Poplar.

London UndergroundThe London Underground (also known simply as the Underground or by its nickname the Tube) is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex and Hertfordshire in England.

It is now part of the Circle, District, Hammersmith & City and Metropolitan lines.
Automatic train operationAutomatic train operation (ATO) is a technology used to automate the operation of trains. The degree of automation is indicated by the Grade of Automation (GoA), up to GoA4 in which the train is automatically controlled without any staff on board. On most systems for lower grades of automation up to GoA2, there is a driver present to mitigate risks associated with failures or emergencies. Driverless automation is primarily used on automated guideway transit systems where it is easier to ensure the safety due to isolated track lines.
River ThamesThe River Thames (tɛmz ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Henley-on-Thames and Windsor.

Port of LondonThe Port of London is that part of the River Thames in England lying between Teddington Lock and the defined boundary (since 1968, a line drawn from Foulness Point in Essex via Gunfleet Old Lighthouse to Warden Point in Kent) with the North Sea and including any associated docks. Once the largest port in the world, it was the United Kingdom's largest port as of 2020. Usage is largely governed by the Port of London Authority ("PLA"), a public trust established in 1908; while mainly responsible for coordination and enforcement of activities it also has some minor operations of its own.
