Continuity mistake: Sam and Hetty are talking at her desk. There are two cups of tea on the desk. The ear of one of the cups is on the left in one shot, then on the right on the next.
Factual error: When the stolen freight train is braking, the air pipe becomes disconnected. This should trigger the brakes on the train, but the train keeps going with no brakes.
