I tried to watch this on Wednesday, and wished that I hadn't!
It is, without doubt, the worst film that I've ever watched. I only managed to stay in the cinema for around 20 minutes, as I was completely turned off by the lack of a plot and the thoroughly unlikeable characters. Including the adverts prior to the film, it's around 45 minutes of my life (not to mention the ticket price) that I'm never going to get back.
I can't therefore comment about the method of driving the train, as I didn't get that far.
