A roller coaster is a type of amusement ride employing a form of elevated railroad track that carries passengers on a train through tight turns, steep slopes, and other elements usually designed to produce a thrilling experience. Trains consist of open cars connected in a single line, and the rides are often found in theme parks around the world. Roller coasters first appeared in the 17th century, and LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, based on the Switchback Railway which opened a year earlier at Coney Island.
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.
Bolliger & Mabillard, officially Bolliger & Mabillard Consulting Engineers, Inc. and often abbreviated B&M, is a roller coaster design consultancy based in Monthey, Switzerland. The company was founded in 1988 by engineers Walter Bolliger and Claude Mabillard, both of whom had worked for Giovanola.
A brake run on a roller coaster is any section of track that utilizes some form of brakes to slow or stop a roller coaster train. There are various types of braking methods employed on roller coasters, including friction brakes, skid brakes, and magnetic brakes. The most common is a fin brake, an alternative name for a friction brake, which involves a series of hydraulic-powered clamps that close and squeeze metal fins that are attached to the underside of a coaster train. Roller coasters may incorporate multiple brake runs throughout the coaster's track layout to adjust the train's speed at any given time.
A spinning roller coaster is a roller coaster with cars that rotate on a vertical axis.
Out and back refers to the layout of a roller coaster. An out and back coaster is one that climbs a lift hill soon after leaving the station, races out to the far end of the track after the initial drop, performs a 180 degree turn and then returns to the station. Some out and back coasters perform more complicated turns at the far end of the track.
A dual-tracked roller coaster is a roller coaster that consists of two tracks. They can be configured as racing, dueling, or Möbius loop roller coasters. Some dual-track coasters operate only one track side at a time, including Rolling Thunder and Colossus. Others may opt to run one side facing frontward and one side facing backward.
Raging Bull is a steel roller coaster located at Six Flags Great America in Gurnee, Illinois. Designed by Werner Stengel and manufactured by Bolliger & Mabillard (B&M), the ride opened to the public on May 1, 1999.

A hypercoaster is a roller coaster with a height or drop measuring at least 200 feet (61 m). The term was first coined by Arrow Dynamics and Cedar Point in 1989 with the opening of the world's first hypercoaster, Magnum XL-200, which features a height of 205 feet. The next hypercoaster, Pepsi Max Big One, opened five years later at Blackpool Pleasure Beach featuring a height of 213 feet (65 m).
Apollo's Chariot is a steel roller coaster at the Busch Gardens Williamsburg amusement park in James City County, Virginia, United States. The ride was the first Hyper Coaster designed by Swiss firm Bolliger & Mabillard. It officially opened to the public on March 27, 1999. This coaster is themed to the Greek and Roman god Apollo, who is the god of the sun, music, and healing. Apollo used his chariot to control the directions of the sun.
Alpine Bobsled was a steel bobsled roller coaster located at the Six Flags Great Escape and Hurricane Harbor amusement park in Queensbury, New York.

Volcano: The Blast Coaster, or simply Volcano, was an inverted roller coaster located at Kings Dominion in Doswell, Virginia, United States. Designed by Werner Stengel, it was the first launched roller coaster manufactured by Intamin and the first of its kind in the world to be inverted. Its launch mechanism utilized linear induction motor (LIM) technology. After a series of delays, Volcano opened to the public on August 3, 1998. A portion of the ride was enclosed inside an artificial mountain, constructed in 1979, which previously housed other attractions. Following nearly two decades of operation, Volcano abruptly closed a few weeks into the 2018 season, and the closure became permanent during the following offseason.

Thunderhawk is a wooden roller coaster with an out-and-back layout located at Dorney Park & Wildwater Kingdom in Allentown, Pennsylvania. Originally opening as The Coaster in 1924, Thunderhawk is the oldest operating roller coaster in the Cedar Fair chain, and one of the oldest in the world still in operation. It was manufactured by Philadelphia Toboggan Coasters (PTC) and designed by Herbert Paul Schmeck.
The Racer is a wooden, racing roller coaster located at Kings Island amusement park in Mason, Ohio. It was designed by John C. Allen, well-known for his contributions to roller coasters during the mid-twentieth century, and debuted at the park's grand opening in 1972. It was thrust into the national spotlight after being featured in an episode of the popular TV sitcom The Brady Bunch in 1973 and is often recognized for playing a vital role in the roller coaster renaissance of the 1970s. The Racer inspired similar designs in other roller coasters, such as Racer 75 at Kings Dominion and the now-defunct Thunder Road at Carowinds. The Racer is also one of the few original Kings Island attractions still in operation today.
Figure 8 roller coasters are a category of roller coasters where the train runs through a figure 8 shaped course before returning to the boarding station. This design was one of the first designs to be featured in roller coaster design, along with the out and back roller coaster. The figure 8 design allowed for more turns than the out and back design, offering riders an alternative experience.
Indiana Jones and the Temple of Peril is a roller coaster attraction at Disneyland Park (Paris). It opened on 30 July 1993. Based on the Indiana Jones films, guests are taken on an adventure riding in a mining train through a lost temple. The attraction was sponsored by Esso.
An Impulse roller coaster is a form of a launched inverted roller coaster manufactured by Intamin. The first Impulse roller coaster appeared in Japan, and the ride type has since evolved to include four specific layouts, three of these varieties being built in the United States. It uses LIMs to launch a train out of the station and up a vertical spiral. The train then falls backward, is powered again through the station, and heads up a back tower. The train then falls forward, and continues in this fashion for a total of 2½ cycles per ride. On the final forward launch, with a slightly reduced speed, the train is sent up the front tower, and brakes then deploy on the launch track. The train then slows down and heads back into the station.
SkyLoop is a type of steel roller coaster manufactured by Maurer AG. There are currently 10 SkyLoops operating worldwide, nine of which are identical XT 150 models, and one of which is an extended XT 450 model.
