Trivia: The studio that made the Thomas and Friends show didn't have the budget to buy a bunch of coaches, so in order to save money, they painted one side tan and the other side green and white. This probably explains why the coaches keep getting flipped. They always show the same side of the coaches so that no one will tell the difference. This resulted in a goof.
Trivia: According to a SiF interview, Fergus' model was damaged during filming of the landslide scene. His model still worked, but the flywheel couldn't turn anymore, nor could he puff anymore steam. This could be why he never appeared again after the airing of the seventh season.
