Three London Underground services cross the district, serving a total of 8 stations: the District and Hammersmith and City lines share track between Aldgate East and Barking. The Central line has stations at Bethnal Green and Mile End - where there is an interchange to the District line. A third central line station, at Shoreditch, has been proposed as the Central line runs within close proximity of Shoreditch High Street station. If built, it will be situated between the existing stations at Bethnal Green and Liverpool St. The Jubilee line has one stop at Canary Wharf.
