Corrected entry: When Hero Boy is about to leave the car containing the abandoned toys, it's plainly visible that there are two doors, one on his car, and one on the next car. He goes through the door in his car, slams it behind him, and is immediately in the next car, having gone through only one door.

Correction: The car carrying the abandoned toys was the car Hero Boy, Hero Girl, and the conductor entered immediately after climbing off the locomotive's tender, meaning that it was the first car in the train. When Hero Boy fled the car and only slammed one door behind him, it was a time skip. It was meant to suggest that he ran frightened through the numerous (and changing amount of) passenger cars before reaching his, the second-to-last car of the train.
