Culdee is a mountain engine named after Culdee Fell, the mountain his railway climbs. Culdee was built at the Swiss Locomotive and Machine Works in Winterthur, Switzerland, in 1896, and was the first to be used in the test runs on the Culdee Fell Railway. He was also the last mountain engine on Sodor to travel to Switzerland for an overhaul, in the 1960s.
Culdee has his own coach, named Catherine.
Culdee is based on Snowdon of the Snowdon Mountain Railway.
Culdee is painted purple with orange lining.
