The Spotless Record

A new tank engine from the LMS called Arthur arrives on the island. He has a spotless record which means he's never been naughty or left a mess. The Fat Controller puts him to work with Thomas and Percy. Arthur's first job on the island is to take a train of closed vans full of fruit to market. The trucks start to sing rudely and Thomas then plays a trick and tells Arthur that The Fat Controller doesn't like the trucks singing and that Arthur should stop them from doing just that. This soon leads to a terrible accident...
