Trainiacs!

Nick had a great time visiting his cousins in Baltimore, so great that he missed his train back home. There is only one train that will get him home in time to go to school tomorrow, the super-creepy Night Owl. Worst of all, some bad guys are on the Night Owl, looking for a kid who looks a lot like Nick. Soon they're chasing Nick all over the train, through the door, up to the roof, and the train's heading into a tunnel!.
