Culdee Fell

Culdee Fell is a mountain on the Island of Sodor. It has the reputation of being the highest point on Sodor, with its summit metres 2048 feet above sea level. The Culdee Fell Railway climbs this mountain's southwest side. Culdee, #4 on the Culdee Fell Railway, is named after this mountain.

In the television series, Culdee Fell is a mountain on the Skarloey Railway, first mentioned in the ninth season.

Translated from Sudric, it means "The Mountain of the Companion of God". This most likely sources from the fact that St. Machan (the patron saint of Sodor, who lived during the sixth century) lived in a nearby cave.
