Freddie is the warhorse engine of the Skarloey Railway. In his youth, he was known as "Fearless Freddie," and he was the daredevil of the hills, known for being fast, fun and of course, fearless. As a result of having worked on the narrow gauge line many years before, Freddie knows the route, as well as many hidden tracks, like the back of his buffers and he can use this to his advantage. Although he is now a much older engine, Freddie is still full of boyish charm, has his wits about him.
