Abstract
An amusement park ride with one or more evacuation zones. The ride includes a track with a rail defining a ride path. The ride path includes at least one evacuation zone along a first length of the track at a first height and a non-evacuation zone along a second length of the track with one or more portions at a second height greater than the first height. The track is sloped in the non-evacuation zone toward the evacuation zone. The ride includes a vehicle supported on the rail via roller elements such as load bearing wheels. The ride includes a drive assembly that provides a driving force to selectively move the vehicle along the ride path. The drive assembly is adapted to automatically disengage from the vehicle upon loss of power. The vehicle is free rolling upon loss of power to travel to the evacuation zone based on gravity.
