Thomas & Friends: Season 8, Episode 15

8 - 15: Squeak, Rattle & Roll

Diesel tries to rattle Gordon by saying steam engines will be scrapped. Gordon doesn't believe him, but starts to worry when he hears a squeaking and rattling. If he slows down, the noise disappears, so he decides to go slowly, even when he has to take The Fat Controller and some children on a boating trip.
