When Rebecca tells James, he could be a comic-book super-engine, he takes her seriously, and Rail Rocket is born! Thomas helps Ace to overcome his fear of animals and joins Shankar for a fancy dress contest. Meanwhile, Ruth turns an old windmill into an energy-efficient workshop and invents a walking bridge! Cleo's on a mission to save the snow, and Nia's bright idea guides Harold through a storm.
