Continuity: When the train arrives in the street the room of the boy's chamber shows moving lights from a (stopping) passing train. The room of the boy is upstairs and the train doesn't pass at that level. Outside you can also see that the light from the windows of the carriages shines downwards on the snow, but not on the house.

Audio problem: When the elves are marching around, listen to the footstep sounds and watch their feet. A lot of times the noise and movements don't match. This is especially apparent when the five elves who have been taking wish calls go to the transporter.

Continuity: Nearing the end of the scene where the boy and hobo are jumping from the roof of one passenger car to the next on skis, the camera shot changes from a close-up to a distant view. In this distant view you can plainly see that they have just two more passenger cars to jump onto before hitting the coal hopper. However, when the camera returns back to a close-up shot, they jump three passenger cars before the boy hits the coal hopper.

Deliberate "mistake": When the boy and the girl are at the front of the train when they find the girl's lost ticket, it is fluttering about in the air. The train is moving quite fast and the ticket should have been blown back like the snow. They obviously did this so the children could catch the ticket.

Continuity: After the Hot Chocolate scene, the little girl takes a cup to the boy in the last car. When she leaves her seat, there is no ticket there, but the boy sees that she left it behind.

Continuity: After the kids reach the North Pole and they line up outside of the train, Hero Boy and Girl are at the back of the line and we can see the other kids in front of them. In the next few shots, they discuss helping the Lonely Boy. When the camera comes back to the same point of view of the boy and girl being in line, the rest of the kids have disappeared behind them.

Continuity: When the boy runs out of his house, as the train is arriving, they make a point of showing his footprints in the snow along with his sliding leaving long marks. However, when they pan back it is his footprints that are gone.
