On the night of 13 October 1940, during the Blitz, a lone German aircraft dropped a single bomb on houses to the north of Bounds Green station. The destruction of the houses caused the north end of the westbound platform tunnel to collapse. As a result, train services between Wood Green and Cockfosters were disrupted for two months. On 11 August 1948, a passenger train was derailed when the front and rear bogies of a carriage took different routes at a set of points at the station. On 7 July 2005, a bomb exploded on a train travelling between King's Cross St. Pancras and Russell Square. Train services between Hyde Park Corner and Arnos Grove were disrupted until 4 August of the same year.
