The curved link to the Metropolitan Railway had to be particularly sharp owing to the location of Aldgate East station.

As part of the London Passenger Transport Board's 1935–1940 New Works Programme, the triangular junction at Aldgate was enlarged to allow for a much gentler curve and to ensure trains that were held on any leg of the triangle did not foul any signals or points elsewhere.

[10][11] It was designed to be completely subterranean providing a much-needed pedestrian underpass for the road above.

[note 1] This reduced operational overheads and journey times because the new Aldgate East had effectively replaced two other stations.

The same councillor has also campaigned to have Shoreditch High Street railway station renamed "Banglatown".

District and Hammersmith & City line trains run into Aldgate East from Liverpool Street and Tower Hill along two sides of the above triangle and pass through the site of the earlier station, most of which has been obliterated by the current junction alignment although the extensive width and height and irregular shape of the tunnel can be observed.

During off-peak times, 3 trains per hour from Wimbledon terminate at Barking (as of December 2014).
