Continuity mistake: Throughout most of the sequence where Thomas pulls the troublesome trucks, the trucks keep changing positions numerous times and many of the trucks disappear and reappear. Also, in a few scenes, there is only 1 truck or just 5 trucks.
Continuity mistake: At the beginning of the episode, the order in the sheds is Henry, Thomas, Gordon, James and Edward. But, when Thomas is complaining, the order is now Thomas, Gordon, James, Edward and Henry.
Continuity mistake: When Edward is pushing trucks over a turntable, when he stops, he is very close to the trucks, when the camera changes, he moves back a bit. (Note the tank the Fat Controller is standing on).
