I think I remember seeing this a long time ago before I was modeling 3R. Maybe even in the theatre. Watched it for the second time last night this time with an eye on the trains. According to the Wikipedia report on the film these are all EMD: A GP40 in the lead followed by an F7 then two GP7s. In addition to the great performances by the lead actors, the footage of the trains roaring thru the stark winter landscape on snow covered tracks is amazing. Without any CGI and minimal special effects the raw power of the runaway engines is perfectly captured -- to me anyway. I liked Unstoppable but not nearly as much. What a fantastic film.
