All Amusement Rides

Large structures built to carry riders for fun and thrill, where the engineering is in the track, the wheel, the supports and the safe handling of heavy loads in motion. The group includes the Ferris wheel, a rotating upright wheel with passenger cars, and the roller coaster, which carries a train over elevated track through hills and turns. An invention belongs here when the cited article describes it as an amusement ride. It excludes ordinary bridges, roads and railways built for transport.
