Visible crew/equipment: When Bill and Ben go by a level crossing, the top of the set is visible.
Wrong Road - S2-E22
Character mistake: The narrator refers to the brake coach as the guard's van.
Percy Takes the Plunge - S2-E11
Deliberate mistake: When Percy is being loaded onto the flatbed, Diesel appears, but he is not introduced until "Pop Goes the Diesel" (episode after this). This is likely because "Pop Goes the Diesel" was produced before this episode.
Suggested correction: There is nothing in the show suggesting that the episodes are shown in chronological order.
Thomas and the Missing Christmas Tree - S2-E26
Visible crew/equipment: At the end of the episode, a blue studio light is visible, which is then covered up by a crew member.
Other mistake: Loads of scratches are visible on Gordon in the last shot of him.
Other mistake: The Breakdown Train to the left, in the opening scene, is derailed.
Wrong Road - S2-E22
Revealing mistake: Wires to power the lamps are very visible on Gordon's and Edward's buffers, and bulbs are also sticking out from both their lamps.
