Culdee Caves

Culdee Caves is a famous landmark on the Skarloey Railway. Originally, Duncan was going to take holidaymakers to see the Culdee Caves, however his job was given to Bertie instead. It was only mentioned in the ninth season episode, Duncan and the Old Mine. However, it may have been mistaken for St. Machan's Cave, a cave on the northern side of Culdee Fell.

Trivia
