I loved the use of sound in this opening scene. All we hear are the workings of the train. No one speaks. There is no music yet. It made me tense because I did not know if the scene was going to end badly for one of the two men. But then to hear the upbeat music and see the train approaching the city station, the tension releases. I want to continue to watch the entire movie, and hope the same tension and release occurs. I also loved how the music's tempo begins to slow as the train slows down to a stop.
