There are five known windmills on Sodor: the Post Windmill, the Tower Windmill, the Sodor Grain Windmill, Toby's Windmill and one nearby Ruth's Workshop. Four of the five windmills grind wheat grown on Sodor into flour for use in making bread for the residents of nearby villages and one was converted into an electro-magnet generator to power the workshop and gate.
