What is a fairground switchback?

A fairground switchback is a type of amusement ride that consists of a series of interconnected tracks that form a continuous loop. The ride vehicles, which are usually small cars or trains, travel along the track, which features steep inclines, descents, and curves. The cars are pulled up the inclines by a chain or cable, and then gravity takes over as they travel down the descents and around the curves. The ride often features a variety of sound and light effects, as well as decorations such as painted scenery or animatronic figures. Fairground switchbacks are popular attractions at carnivals, fairs, and amusement parks, and are enjoyed by people of all ages.
