Devil's Back, in Sudric, Dreeym-y-Deighan, is a bleak, windy ridge on Culdee Fell traversed by the Culdee Fell Railway. It is the last passing loop before the summit. It was here Godred came off the rails and fell of the ravine. If the winds become too strong on the mountain, passenger trains stop here rather than continuing to the summit. Rescue and supply trains, however, must get through.
