Considering that it's just a film about a runaway train this is surprisingly good. It takes about half an hour to get going but once it's up and running this is a thrill a minute. What's particularly impressive is that there is no use of special effects. The stunts are all real and as one of the documentaries on the disc shows, the helicopters were literally flying just a few feet away from Denzel Washington's head! A good old fashioned action flick.
