Continuity mistake: Multiple scenes: On every exterior shot of the train, you can only see one row of windows across the upper galley section. However, whenever there is a scene shot on the upper 'galley' level, there are two rows of windows, one right above the other. The external shots were filmed using a Chicago Metra train (which uses 'bilevel' galley cars), the internal scenes were filmed on a set in Montreal, Canada.
