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.
A lift hill, or chain hill, is an upward-sloping section of track on a roller coaster on which the roller coaster train is mechanically lifted to an elevated point or peak in the track. Upon reaching the peak, the train is then propelled from the peak by gravity and is usually allowed to coast throughout the rest of the roller coaster ride's circuit on its own momentum, including most or all of the remaining uphill sections. The initial upward-sloping section of a roller coaster track is usually a lift hill, as the train typically begins a ride with little speed, though some coasters have raised stations that permit an initial drop without a lift hill. Although uncommon, some tracks also contain multiple lift hills.
A shuttle roller coaster is any roller coaster that ultimately does not make a complete circuit, but rather reverses at some point throughout its course and traverses the same track backwards. These are sometimes referred to as boomerang roller coasters, due to the ubiquity of Vekoma's Boomerang coaster model.
A spinning roller coaster is a roller coaster with cars that rotate on a vertical axis.
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.
A twister roller coaster is the generic name given to any roller coaster layout which tends to twist or interweave its track within itself several times. It is essentially the opposite of an Out and Back roller coaster, which is often a much more simplistic layout. Twister roller coasters often have the illusion of having small or tight clearances due to the track usually travelling through several support structures. This is known as a head chopper effect.
American Eagle is a wooden racing roller coaster located at Six Flags Great America theme park in Gurnee, Illinois. It was the first wooden roller coaster designed by Intamin of Switzerland and was built in 1981 by the contracting firm Figley-Wright at a cost of $10 million. While most of the records have since been broken, American Eagle had the longest drop and fastest speeds among wooden roller coasters when it debuted and is still recognized as a top racing coaster in the United States.

Thunderhawk is a wooden roller coaster with an out-and-back layout located at Dorney Park & Wildwater Kingdom in Allentown, Pennsylvania.

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.
Eurostar is the world's largest portable inverted roller coaster. Eurostar was designed by Oscar Bruch, who had created and/or operated many portable coasters including Alpina Bahn, Looping Star and Thriller. The inverted coaster was becoming increasingly popular in the mid-1990s, having been introduced to the theme park market by Bolliger & Mabillard. However, B&M were reluctant to attempt a travelling model and so Eurostar was designed by Werner Stengel from a rough layout designed by Bruch. Aspects of the ride were built by many companies from across Europe, under the directorship of the Swiss ride firm Intamin.
Rampage is a wooden roller coaster located at Alabama Splash Adventure in Bessemer, Alabama, US.

Rampage sat dormant for four years, before being renovated in 2014 by owners Dan and Natalie Koch and reopening for the 2015 season.

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.
