The present invention relates to amusement rides, such as roller coasters, installed in amusement parks and the like, which are adapted to allow a vehicle to travel on a track. The ride of the invention has an arrangement such that the track has a missing portion where the vehicle is adapted to transfer from the track on one side of the missing portion to the track on the other side. According to the invention, during the movement of the vehicle across the missing portion, passengers may be seized with the fear that the vehicle is off the track and out of control, thus increasing the thrill of the ride.
