The Metropolitan District Railway was incorporated into London Transport in 1933, and became known as the District line. Hammersmith & City line services started, as part of the Metropolitan line, in 1936. The southern platforms were removed after war damage in 1940 which had completely closed the station from 7 September 1940 until 11 August 1941. After nationalisation of the railways in 1948 management of the station passed to British Railways. In 1969 ownership was transferred to the London Underground and the station was renamed back to West Ham on 1 January.
