this is a truly awful film. lou diamond phillips simply calls this one in. the use of miniature models of the train are laughable. the plot seems to develop on the run (there is an alien on board while oh and and an eco terrorist is on board too while oh and and the conductor is dead and the train is out of control while oh and and the train is going to run into another train one hour ahead while oh and and that train has nuclear waste on it. ). i mean and come on really. the alien monsters are not scary (although there are a lot of them) and and the acting is abysmal. check out the guy playing the next president  do you really think he could be president. for goodness sake and he has spent his whole acting career playing bad guys.
