A roller coaster, or rollercoaster, is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. Passengers ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island. The track in a coaster design does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably Wild Mouse roller coasters, run with single cars.
A wooden roller coaster is a type of roller coaster classified by its wooden track, which consists of running rails made of flat steel strips mounted on laminated wood. The support structure is also typically made of wood, but may also be made of steel lattice or truss, which has no bearing on a wooden coaster's classification. The type of wood often selected in the construction of wooden coasters worldwide is southern yellow pine, which grows abundantly in the southern United States, due to its density and adherence to different forms of pressure treatment.

A side friction roller coaster is an early roller coaster design invented by Edward Joy Morris. The design introduced side-friction wheels to help prevent trains from derailing during curved portions of the track. In addition to weight-bearing wheels traditionally located on the underside of each train car, friction wheels were added to both sides, which roll perpendicular along the inner edge of the track.
