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 steel roller coaster is a type of roller coaster classified by its steel track, which consists of long steel tubes that are run in pairs, supported by larger steel columns or beams. Trains running along the track typically rely on wheels made of polyurethane or nylon to keep each train car anchored to the track. The introduction of tubular steel drastically changed roller coaster innovation, allowing for greater speeds, higher drops, and more intense elements such as inversions.
A roller coaster inversion is a roller coaster element in which the track turns riders upside-down and then returns them to an upright position. Early forms of inversions were circular in nature and date back to 1848 on the Centrifugal railway in Paris. These vertical loops produced massive g-force that was often dangerous to riders. As a result, the element eventually became non-existent with the last rides to feature the looping inversions being dismantled during the Great Depression. In 1975, designers from Arrow Development created the corkscrew, reviving interest in the inversion during the modern age of steel roller coasters. Elements have since evolved from simple corkscrews and vertical loops to more complex inversions such as Immelmann loops and cobra rolls. The Smiler at Alton Towers holds the world record for the number of inversions on a roller coaster with 14.
Arrow Dynamics was an American manufacturing and engineering company that specialized in designing and building amusement park rides, especially roller coasters. Based in Clearfield, Utah, the company was the successor to Arrow Development (1946–1981) and Arrow Huss (1981–1986), which were responsible for several influential advancements in the amusement and theme park industries. Among the most significant was tubular steel track, which provided a smoother ride than the railroad style rails commonly used prior to the 1960s on wooden roller coasters. The Matterhorn Bobsleds at Disneyland, built in 1959, was Arrow's first roller coaster project.
Matterhorn Bobsleds is a attraction that consists of a pair of intertwined steel roller coasters running through a fabricated mountain. It is located at Disneyland in Anaheim, California and is modeled after the Matterhorn, a mountain in the Alps on the border between Switzerland and Italy. It is the first known tubular steel track roller coaster. Located on the border between Tomorrowland and Fantasyland, it employs forced perspective to seem larger.
The launched roller coaster is a type of roller coaster that 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 roller coasters in the world.
Canobie Lake Park is an amusement park in Salem, New Hampshire, located about 31 miles (50 km) north of Boston. It was founded as a trolley park on the shore of Canobie Lake in 1902. Three local families currently run the park, which draws visitors from throughout the New England and Mid-Atlantic regions. Canobie Lake Park's age and history inspired author Stephen King to use rides and elements from the park in his Joyland novel. It is one of only thirteen trolley parks still operating in the United States as of 2021.
Ronald Valentine Toomer was an American roller coaster designer credited for designing 93 roller coasters around the world. He graduated from the University of Nevada, Reno in 1961 with a degree in mechanical engineering and was a part of the design team responsible for the Apollo spacecraft heat shield.
Sky Whirl was the name of two amusement rides which featured triple Ferris wheels. Both debuted in 1976 at the California's Great America and Six Flags Great America amusement parks. The ride in Santa Clara closed in 1997, and the ride in Gurnee closed in 2000. Two additional triple Ferris wheels were later built for the Seibu-en and Lotte World parks in Japan and South Korea (1989–97), respectively. All four rides were manufactured by Waagner-Biro and brokered by Intamin.
The Bat was a suspended roller coaster located at Kings Island amusement park in Mason, Ohio. Designed by Arrow Development, it was billed as the "first of its kind" in the world when it opened to the public on April 26, 1981. The suspended coaster concept was a radical departure from traditional roller coaster design, where guests ride below the track instead of above. Previous attempts to build coasters that hang from the track were unsuccessful and date as far back as the early 20th century. Arrow solved issues by utilizing modern technology in the design, including its tubular steel track developed in 1959 for Disneyland's Matterhorn Bobsleds.
Comet is a wooden roller coaster at Hersheypark in Hershey, Pennsylvania. It is located in the Hollow section of Hersheypark, next to Skyrush. Built in 1946 by the Philadelphia Toboggan Coasters (PTC) of Philadelphia, Pennsylvania, the coaster features a double out and back track layout. When built it was jointly owned by Hershey Park and PTC. The maximum speed is 50 miles per hour (80 km/h).
Runaway Mine Train is a steel roller coaster located in the Boomtown section of Six Flags Over Texas in Arlington, Texas. Built in 1966, Runaway Mine Train is the oldest roller coaster in the park.
Chance Rides is a roller coaster and amusement ride manufacturer. Originally founded in 1961, the current company was formed on May 16, 2002, when the former Chance Industries Inc. emerged from bankruptcy. The main office and manufacturing facility are located in Wichita, Kansas.
Canobie Corkscrew was a steel sit-down roller coaster located at Canobie Lake Park amusement park in Salem, New Hampshire. Canobie Corkscrew is one of many Arrow Development Corkscrew models produced between 1975 and 1979. The coaster was removed in 2021.
A mine train roller coaster is a steel roller coaster whose trains often depict a set of mine carts, with the forward-most car or portions of it sometimes resembling a small steam locomotive. Most mine train roller coasters are themed in the style of a mine, a Western scene, or simply a mountain range.
Roller coaster amusement rides have origins back to ice slides constructed in 18th-century Russia. Early technology featured sleds or wheeled carts that were sent down hills of snow reinforced by wooden supports. The technology evolved in the 19th century to feature railroad track using wheeled cars that were securely locked to the track. Newer innovations emerged in the early 20th century with side friction and underfriction technologies to allow for greater speeds and sharper turns. By the mid-to-late 20th century, these elements intensified with the introduction of steel roller coaster designs and the ability to invert riders.
Untamed is a steel Euro-Fighter roller coaster located at Canobie Lake Park in Salem, New Hampshire.
The Bobsleds is an in-house hybrid roller coaster at Seabreeze Amusement Park in Irondequoit, New York. The coaster opened in its current form in 1962, making it one of the first roller coasters in the world to use steel tubular track, second only to the Matterhorn Bobsleds at Disneyland.
