Abstract
An amusement ride attraction has an anti-roll back track with stops or cross bolts covered by a continuous brush material. A vehicle such as a roller coaster car or water flume boat has an anti-roll back pawl which rides above the fiber material on skis, when the vehicle moves forward. If the vehicle begins to move backward, the skis move downwardly through the brush material and the pawl engages a stop on the track, to prevent further reverse movement. The brush material prevents the pawl from banging over each of the stops on the track, thereby reducing noise and wear.
