On 13 February 1919 there was an accident at Wood Street when a passenger train ran into an empty stock train. Five people were injured – none seriously. The cause was a signal failure. In 1923 the Great Eastern Railway became part of the London and North Eastern Railway, which in turn was merged into British Railways Eastern Region following nationalisation in 1948. When construction of the London Underground's Victoria line was given parliamentary approval in 1955, the plan was to build the line past Walthamstow Central station to Wood Street, where the line would surface to terminate next to the British Railways station, on land previously used as a coal depot. Before construction work started, a decision was made in 1961 to omit the section beyond Walthamstow Central. The line was electrified in 1960, and electric services commenced on 12 November. At first Class 305 EMUs were used, but initial technical problems led to their replacement by Class 302 and Class 304 EMUs. The station had a goods depot, which closed on 6 May 1968. In April 1994 Railtrack took over responsibility for the operation of the infrastructure. Train services have been operated since then by West Anglia Great Northern, National Express East Anglia, Abellio Greater Anglia and, , by London Overground.
