The locomotive, filmed at Lydd Town station, was K&ESR No.3 hired from the nearby Kent & East Sussex Railway - its ownership being disguised by canvas covers over the tanks. Better known as No.3 "Bodiam" and now jointly owned by The Terrier Trust and the K&ESR, the locomotive frequently hauls trains between Tenterden Town and Bodiam, close to the famous National Trust castle. Originally London Brighton & South Coast Railway No.70 "Poplar" of 1872, the locomotive was sold to the antecedent of the K&ESR, the Rother Valley Railway, in 1901.
