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.
Kennywood is an amusement park in West Mifflin, Pennsylvania, just southeast of Pittsburgh. The park opened on May 30, 1898, as a trolley park attraction at the end of the Mellon family's Monongahela Street Railway.
Knoebels Amusement Resort is a family-owned and operated amusement park, picnic grove, and campground in Elysburg, Pennsylvania. Opened in 1926, it is the United States's largest free-admission park. The park has more than 60 rides including three wooden roller coasters, three steel roller coasters, a 1913 carousel, and two haunted house dark rides.
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.
The generic roller coaster vertical loop, also known as a Loop-the-loop, or a Loop-de-loop, where a section of track causes the riders to complete a 360 degree turn, is the most basic of roller coaster inversions. At the top of the loop, riders are completely inverted.
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.
Anton Schwarzkopf was a German engineer who founded Schwarzkopf Industries GmbH, a German manufacturer of roller coasters and other amusement rides that were sold to amusement parks and travelling funfairs around the world.
Six Flags Magic Mountain, formerly known and colloquially referred to as simply Magic Mountain, is a 209-acre (85 ha) amusement park located in Valencia, California, 35 miles (56 km) northwest of downtown Los Angeles. It opened on May 29, 1971, as a development of the Newhall Land and Farming Company and Sea World Inc. In 1979, Six Flags purchased the park and added "Six Flags" to the park's name.
A pirate ship is a type of amusement ride based on pirate ships, consisting of an open, seated gondola which swings back and forth, subjecting the rider to various levels of angular momentum. A variant where the riders must pull on ropes to swing the ride is known as a swing boat.
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.
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.
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.
The National Amusement Park Historical Association (NAPHA) is an international organization dedicated to the preservation and enjoyment of the amusement and theme park industry – past, present and future.
Alpine Bobsled was a steel bobsled roller coaster located at the Six Flags Great Escape and Hurricane Harbor amusement park in Queensbury, New York. Manufactured by Intamin, the coaster first opened to the public in 1984 at Six Flags Great Adventure. It was later relocated to Six Flags Great America in 1989, then to Six Flags Great Escape in 1998. Alpine Bobsled closed permanently on September 4, 2023, to make room for The Bobcat.
A bobsled roller coaster is a roller coaster that uses a track design that is essentially a "pipe" with the top half removed and has cars that are sent down this pipe in a freewheeling mode. The name derives from the great similarity to the track design used for the winter sport of bobsleigh.
The Whip was a ride originally designed and built by W.F. Mangels Company of Coney Island, New York, United States. William F. Mangels patented the ride in 1914 and it soon became extremely popular.
Rockin' Tug is a flat tugboat ride manufactured by Zamperla. The ride is manufactured in both traveling and park versions. It is the first of a line of new "halfpiperides". Zamperla's Disk'O is another popular ride from that "family". The difference is that the Rockin' Tug has a friction wheel, while the Disk'O is powered driven.
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.
