Wilfred is the third engine on the Culdee Fell Railway.
Wilfred was built at the Swiss Locomotive and Machine Works in Winterthur, Switzerland, in 1895. In 1900, he arrived on Sodor during the opening of the Culdee Fell Railway.
When Culdee returned from an overhaul, Ernest and Wilfred informed him about changes that happened to the railway. Later, Wilfred and his coach were later delayed at the Summit after Lord Harry derailed at the points. Culdee and Wilfred teased him for being a "wreck".
