The Spotless Record is the ninth episode ever made in Season 7.
A new tank engine with a "spotless record" named Arthur arrives. Arthur's first job is to take a train of fruit to market, but the trucks tease Arthur. Thomas, sensing a chance for mischief, advises Arthur to tell the trucks to stop singing. Arthur does and the furious trucks decide to pay him out. On Gordon's Hill, they bump forward and crash into Duck's train, spraying fruit everywhere. When Thomas arrives to help, he confesses the incident was his fault, and gets to work. Arthur is later having a washdown when Thomas apologizes and the two become friends.
- In Michael Brandon's narration, when he reads the title, he only says "Spotless Record".
