Castor Railway Station was a station serving the villages Castor and Ailsworth in Cambridgeshire. It was on the old London and North Western Railway Northampton to Peterborough line. On 3 January 1945 the station was badly damaged by a V1 attack. The station closed in 1957 but trains between Rugby and Peterborough East continued to run until the line itself closed in 1966. The line between Wansford and Peterborough has since been reopened as the Nene Valley Railway, although Castor station itself remains closed.
