I am currently researching miniature/narrow gauge railways that are currently in operation in U.K. zoos and safari parks. So far I have looked into those in service at Whipsnade, Longleat, South Lakes and Twycross. I am also interested in Thomasland that operates at Drayton Manor. Firstly, may I enquire about railways that may operate in other zoos/safari parks, both past and present, and regarding the systems that did operate in parks that are unfortunately no longer open, what happened to the rolling stock, track and other features, are any of these still in operation in other establishments in the UK?, I understand that the closed Cricket St. Thomas Wildlife Park had a very good railway in service, does anyone know what happened to it when the park closed?. Any help or information regarding these matters would be very much appreciated, Roy.
