In the middle-end part of the movie [Hugo](http://www.imdb.com/title/tt0970179/), there is a train incident (symbolizing the [1895 Montparnasse Train Wreck](http://en.wikipedia.org/wiki/Montparnasse_derailment)) in the station. It seems pretty strange that the train incident is included in the movie, which happened at a different time than in the setting of the Hugo movie itself.

**What is Scorsese trying to portray by including the incident inside the Hugo movie?**
