Plot hole: When Duck and Diesel leave the shed, Diesel follows Duck instantly, but the tracks they are on both lead to the turntable. As they are on different tracks to each other, it would be impossible for Diesel to follow Duck that quickly as the turntable could only be set to one track at a time.
Bill and Ben: We're not playing. We're rescuing our trucks.
Trivia: The events of this episode were remade in CGI for the 2015 special, The Adventure Begins.
