Following the end of World War II Harringay reopened on the 4th April 1947.
They resumed league racing in the National League Division One under the promotion of Fred Whitehead on behalf of the Greyhound Racing Association Ltd.
Unfortunately this first season back into league racing was marred by the death of the Wembley rider Nelson Wilson following an accident on the track from which he subsequently died.
Although there was a change of management in 1950, George Kay taking over as promoter this time on behalf of GRA Ltd. Racing continued but was not to do so for much longer and falling spectator numbers made the continuation of racing at Harringay unviable and so the management staged many double headers in order to close the season as soon as possible and regular Speedway meetings ended mid August 1954.
