Abstract
An amusement ride system according to the present invention comprises a pair of rails extending at a fixed distance from each other, and a passenger car located between the rails and traveling along the rails. A plurality of wheel units are provided on either side portion of the car, along the rails. Each wheel unit includes a set of wheels, which are in rolling contact with each corresponding rail, so as to hold it between them. The middle portion of the rail pair is twisted around a central axis between the rails, thus forming at least one twist region. As the car runs past the twist region of the rails, therefore, it is rotated around the central axis, following the twist of the rails.
