X-Scream consists of a straight piece of track similar to that of a conventional roller coaster, which carries a single open-top car. Riders are secured by lap bar restraints. The trackway pivots vertically in a see-sawmotion, letting the car rollbackward and forward along the length. The ride car is allowed to roll quickly forward to the end of the track, past the edge of the building, before braking sharply. The rollingback and forth of the car and the rocking of the track is programmed to take the rider by surprise and feel like they are at risk of falling from the precipice of the building.
