Aldgate East tube station

By 1912 the DR was running eight-car trains that were too long for the platforms. As well as causing problems for passengers alighting from the eighth carriage, DR trains in the eastbound platform could block the points and prevent westbound Met trains from departing.{{sfn|Connor|1996|pp=6-7}} The DR and Met drew up plans to extend the platforms but could not agree on how to share the costs and no progress was made.{{sfn|Connor|1996|pp=6-8}} In 1914, a larger [[Harry Wharton Ford]]-designed station building was opened.{{sfn|Connor|1996|p=8}} The DR and the Met were incorporated into [[London Passenger Transport Board|London Transport]] on 1 July 1933 and became known as the [[District line|District]] and [[Metropolitan line|Metropolitan]] lines.{{sfn|Horne|2019|p=344}}

The eastern section of the District line was very overcrowded by the mid 1930s. Growth was constrained by the [[flat junction]]s west of the station.{{sfn|Horne|2019|p=353}} Most Metropolitan line passengers interchanged to District line services at Aldgate East, which was increasing dwell times.{{sfn|Horne|2019|pp=353-354}} In order to relieve this, the peak-hours Metropolitan line service was diverted to Barking in 1936.{{sfn|Horne|2019|p=354}} With the station now under single ownership, a number of improvements could be made. These included providing a subway connection to a new exit on the south side of Whitechapel High Street, improving circulation by adding an entrance at the east end of the platforms, and remodelling the junctions to the west of the station to allow longer eight-car Metropolitan line trains to operate to Barking.{{sfn|Connor|1996|p=8}}

As part of the [[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.{{sfn|Howson|1967|p=47}} The new Aldgate East platforms were sited almost immediately to the east of their predecessors with one exit facing west toward the original location and another at the eastern end of the new platforms. The new station opened on 31 October 1938 and the earlier station closed permanently the previous night.H.V.

It was designed to be completely subterranean providing a much-needed [[Subway (underpass)|pedestrian underpass]] for the road above. In order to accommodate the space needed for the underpass, the existing track needed to be lowered by more than {{Convert|7|ft||0|spell=in}}. To achieve this task whilst still keeping the track open during the day, the bed underneath the track was excavated and the track held up by a timber trestle framework. Once excavation was complete and the new station had been constructed around the site, an army of over 900 workmen lowered the whole track simultaneously in one night using overhead hooks to suspend the track when necessary.{{sfn|Howson|1967|p=47-48}} The hooks {{As of |2010 |alt=still remain}}. The eastern exit of the new station was now close enough to [[St. Mary's (Whitechapel Road) tube station|St Mary's (Whitechapel Road)]], the next station along the line, that this could also be closed.{{efn|The station closed on 30 April 1938, six months before the resited Aldgate East station opened.}} This reduced operational overheads and journey times because the new Aldgate East had effectively replaced two other stations.

A campaign was launched by a local councillor in a bid to change the name of the station to [[Brick Lane]] tube station by 2012,
