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 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 steel roller coaster is a roller coaster that is defined by having a track made of steel. Steel coasters have earned immense popularity in the past 50 years throughout the world. Incorporating tubular steel track and polyurethane-coated wheels, the steel roller coasters can provide a taller, smoother, and faster ride with more inversions than a traditional wooden roller coaster.
Top Thrill 2, formerly known as Top Thrill Dragster, is an upcoming launched roller coaster at Cedar Point in Sandusky, Ohio, United States. Originally manufactured by Intamin and designed by Werner Stengel, Top Thrill Dragster opened in 2003 as the tallest and fastest roller coaster in the world, as well as the first strata coaster. It debuted with a height of 420 feet (130 m), a maximum speed of 120 mph (190 km/h), and a total track length of 2,800 feet (850 m). Its speed and height records were surpassed in 2005 by Kingda Ka at Six Flags Great Adventure.
Kingda Ka is a hydraulically-launched steel roller coaster located at Six Flags Great Adventure in Jackson, New Jersey, United States. Manufactured by Intamin and designed by Werner Stengel, Kingda Ka opened as the tallest and fastest roller coaster in the world on May 21, 2005, surpassing Top Thrill Dragster. It is the second strata coaster ever built, exceeding 400 feet (120 m) in height, and the last to remain in operation after Top Thrill Dragster closed in 2021. Both share similar designs, although Kingda Ka's layout adds an airtime hill on the return portion of the track.
Rollercoasters use brakes to slow down, or completely stop the train. Rollercoaster brakes can come in the form of magnetic and physical brakes, manual and automatic brakes, brakes that are on the train, and brakes that are on the track. Brakes have existed for as long as rollercoasters have, but they have evolved over time, going from manual skid brakes, to the highly technical magnetic and friction brakes of today.
The launched roller coaster is a modern form of roller coaster. A launched coaster initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track. This mode of acceleration powers many of the fastest rollercoasters in the world.
Werner Stengel is a German roller coaster designer and engineer. Stengel is the founder of Stengel Engineering, also known as Ingenieurbüro Stengel GmbH.
Scooby-Doo Spooky Coaster is an enclosed steel wild mouse roller coaster located at Warner Bros. Movie World on the Gold Coast, Australia. It is based on the 2002 live action film Scooby-Doo, which was filmed at the studio adjacent to the park at the same time the ride was being constructed. In 2018 the ride underwent a significant theming overhaul and reopened in December under the name Scooby-Doo Spooky Coaster: Next Generation with a new ride storyline, new theming and new special effects. It closed for refurbishment in January 2023 and is set to reopen in 2025.
A rollback occurs on a launched roller coaster when the train is not launched fast enough to reach the top of the tower or hill. It will roll backwards down the tower, and will be stopped by brakes on the launch track. Any roller coaster on which it is possible for a rollback to occur will have these brakes. Intamin, a manufacturer of roller-coasters, refers to the "rollback" as a "short shot".
Oblivion is a steel roller coaster located at Alton Towers in Staffordshire, England. The prototype Dive Coaster model from Bolliger & Mabillard opened to the public on 14 March 1998 and was marketed as the "world's first vertical drop roller coaster".

An Accelerator Coaster is a hydraulically launched roller coaster model from Intamin. The model usually consists of a long, straight launch track, a top hat tower element, and magnetic brakes that smoothly stop the train without making contact. The technology was developed by Intamin engineers as an alternative to electromagnetic launch systems, such as the Linear Induction Motor (LIM) and Linear Synchronous Motor (LSM), that are found on earlier launched roller coasters like the Flight of Fear and The Joker's Jinx. Unlike the earlier linear induction motors, the Accelerator Coaster's launch system exhibits constant acceleration and is capable of reaching greater speeds.
