Continuity mistake: During the hot chocolate scene, the girl places a cup of hot chocolate under her seat. She is given another hot chocolate and puts that one under the seat too, but the original one has vanished.
Suggested correction: The first time the girl puts the cup of hot chocolate next to her on the seat, then later puts it under her seat.
Suggested correction: She puts it beside her then next to the seat.
Suggested correction: As you yourself stated, the whole thing is likely a dream, where "normal" reality doesn't apply. In the "real world", the train would never be able to do any of the things that it does in the film.

Dream or not, it is still a stupidity of the train crew to not secure a pin that could work itself free of the controls of the locomotive.

Dreams are often unrealistic. There is no mistake.
The entry doesn't say anything about the entire trip to the North Pole being a dream.
Agreed. It was never stated that it was a dream considering that Hero Boy lost the sleigh bell only to find it Christmas morning with a note from Santa. And to add, Steamer said that cotter pin was sheared off which caused it to come loose.
