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 .
66-455: 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 . Chance Manufacturing was incorporated in 1961 by Richard H. (Harold) Chance. Harold Chance had been involved in
132-433: A shuttle roller coaster , reverses at some point throughout the course of the ride to traverse the same track backwards. The oldest roller coasters are believed to have originated from the so-called "Russian Mountains", specially constructed hills of ice located in the area that is now Saint Petersburg, Russia . Built in the 17th century, the slides were built to a height of between 21 and 24 m (70 and 80 feet), had
198-501: A 50-degree drop, and were reinforced by wooden supports. Later, in 1784, Catherine the Great is said to have constructed a sledding hill in the gardens of her palace at Oranienbaum in St. Petersburg. The Riding Mountain (a.k.a. La Grande Glisade ) entertainment pavilion designed by Bartolomeo Francesco Rastrelli for Tsarskoye Selo royal residence was built in 1754–1757. In Russian it
264-532: A basis, LaMarcus Adna Thompson began work on a gravity Switchback Railway that opened at Coney Island in Brooklyn , New York , in 1884. Passengers climbed to the top of a platform and rode a bench-like car down the 600-foot (183 m) track up to the top of another tower where the vehicle was switched to a return track and the passengers took the return trip. This track design was soon replaced with an oval complete circuit. In 1885, Phillip Hinkle introduced
330-443: A bracket came off the top of the ride and hit a woman in the head while she was waiting in line. The woman did not die, and she reached a settlement with Cedar Point amusement park in 2023. The ride was subsequently refurbished and modified, and it reopened in 2024 as Top Thrill 2 . Kingda Ka closed on November 10, 2024. Superman: Escape From Krypton , a 415-foot (126 m) coaster, opened in 1997 at Six Flags Magic Mountain . It
396-507: A division of Vekoma Rides, to produce larger wheels such as the Niagara SkyWheel which stands 53.3 m (175 ft) tall. It features 42 air-conditioned cars seating eight passengers per car. According to Chance Rides director Angus Jenkins, the larger wheels are known as observation wheels as opposed to Ferris wheels, since they carry riders in enclosed cars rather than in open seats. On October 19, 2012, Chance Rides announced
462-604: A dozen imitators, but their popularity soon declined. However, during the Belle Epoque they returned to fashion. In 1887, Spanish entrepreneur Joseph Oller , co-founder of the Moulin Rouge music hall, constructed the Montagnes Russes de Belleville , "Russian Mountains of Belleville" with 656 feet (200 m) of track laid out in a double-eight, later enlarged to four figure-eight-shaped loops. In 1827,
528-405: A lift hill, however. A train may also be set into motion by a launch mechanism such as a flywheel, linear induction motor (LIM), linear synchronous motor (LSM), hydraulic launch, or drive tire. Some launched roller coasters are capable of reaching greater speeds using less track when compared to traditional coasters that rely on a conventional lift hill. A brake run at the end of the circuit
594-402: A little carriage and one stands behind, for more there are in it the greater the swiftness with which it goes; it runs on castors and in grooves to keep it on its right direction, and it descends with a wonderful rapidity. Under the hill, is a machine worked by horses for drawing the carriages back again, with the company in them. Such a work as this would have been enormous in most countries for
660-681: A long term license agreement with Bussink Design GmbH for the exclusive rights to manufacture and sell the R80XL Giant Wheel in North America. Chance Rides will market the R80XL, which is over 250 ft (76 m) tall, under an affiliate company, Chance American Wheels. The first R80XL wheel was manufactured by Maurer German Wheels in Munich, Germany, and was delivered to the city early in 2013. The first U.S. version built by Chance
726-552: A mining company in Summit Hill, Pennsylvania constructed the Mauch Chunk Switchback Railway , a downhill gravity railroad used to deliver coal to Mauch Chunk, Pennsylvania – now known as Jim Thorpe . By the 1850s, the "Gravity Road" (as it became known) was selling rides to thrill seekers. Railway companies used similar tracks to provide amusement on days when ridership was low. Using this idea as
SECTION 10
#1732802412431792-427: A new era of roller coaster enthusiasm, which led to a resurgence across the amusement park industry over the next several decades. There are several explanations for the name roller coaster . It is said to have originated from an early American design where slides or ramps were fitted with rollers over which a sled would coast. This design was abandoned in favor of fitting the wheels to the sled or other vehicles, but
858-406: A ratchet and pawl. When riding a roller coaster with a ratchet and pawl system, the sound of clicks can be heard when pulling down the restraint. Hydraulic restraints use a piston and cylinder. Unlike mechanical restraints, there is no feeling of physical or sound of clicks from the restraint being locked in place. Most modern day roller coasters have sensors that are used to make sure each restraint
924-544: A ride. Also, "In a typical year, more than 385 million guests enjoyed in excess of 1.7 billion rides at approximately 400 North American fixed-site facilities". IAAPA is required to report annual ride incidents to the National Safety Council. Roller coasters are divided into two main categories: steel roller coasters and wooden roller coasters . Steel coasters have tubular steel tracks, and compared to wooden coasters, they are typically known for offering
990-446: A roller coaster's computer system. Multiple PLCs work together to detect faults associated with operation and automate decisions to engage various elements (e.g. lift, brakes, etc.). Periodic maintenance and visual inspection by ride engineers are also important to verify that structures and materials are within expected wear tolerances and functioning correctly. Effective operating procedures further enhance safety. Roller coaster design
1056-477: A smoother ride and their ability to turn riders upside-down. Wooden coasters have flat steel tracks, and are typically renowned for producing "air time" through the use of negative G-forces when reaching the crest of some hill elements. Newer types of track, such as I-Box and Topper introduced by Rocky Mountain Construction (RMC), improve the ride experience on wooden coasters, lower maintenance costs, and add
1122-407: A train attempts to enter an occupied block, the stopping mechanisms in all blocks are engaged. Restraints are another critical aspect to roller coaster safety. Roller coasters usually have two different types: Over-the-shoulder-restraints and lap bar restraints. With both, either hydraulic or mechanical safety mechanisms are used within the restraints. Mechanical restraints use a system known as
1188-430: A variety of different experiences. More focus is being placed on the position of riders in relation to the overall experience. Traditionally, riders sit facing forward, but newer variations such as stand-up and flying models position the rider in different ways to change the experiences. A flying model, for example, places riders lying down and facing forward with their chests and feet strapped in. Other ways of enhancing
1254-455: A wood track and steel structure. Other older examples include mine train roller coasters , many of which were built by Arrow Dynamics . The term hybrid became more prominent after the introduction of New Texas Giant at Six Flags Over Texas in 2011. Many in the industry, however, continue to classify coasters strictly by their track type only, labeling them either steel or wood. Modern roller coasters are constantly evolving to provide
1320-408: Is about five or six feet lower, just sufficient to allow for the friction and resistance; and so on to the last, from which they are conveyed by a gentle descent, with nearly same velocity, over a piece of water into a little island. These slides, which are about a furlong and a half in length, are made of wood, that may be used in summer as well as in winter. The process is, two of four persons fit in
1386-458: Is another important aspect that requires a working knowledge of basic physics to enhance ride comfort and avoid harmful strain to the rider. Ride designers must carefully analyze the movement a ride subjects its riders to, ensuring it is within a reasonable tolerance. The human body needs sufficient time to react to sudden changes in force in order to control muscle tension and avoid harmful consequences such as whiplash . Designers typically stay in

#17328024124311452-404: Is locked. If all the restraints are locked, it will send a signal to the ride computer letting it know that it is clear for dispatch. If all restraints are not locked, the train will not be able to move out of the station until each restraint is locked. Braking systems such as pivoting pawls are used on the bottom of the train and on the inclined lift hill. While the cart goes up the lift hill, it
1518-415: Is not typically classified as a strata coaster due to its shuttle coaster design, where trains do not travel a complete circuit. An exa coaster is a type of roller coaster with a height or drop of at least 600 feet (180 m). The term exa was first introduced by Intamin for Falcon's Flight, a 640-foot (200 m) coaster expected to open at Six Flags Qiddiya in 2025. Upon completion, it will be
1584-525: Is referred as "mountain-and-valley railway". German has the word Achterbahn , stemming from Figur-8-Bahn , relating to the form of the number 8 ( acht in German). This is similar to the Dutch Achtbaan , in which acht also means "eight". Roller coaster trains are not typically powered. Most are pulled up a lift hill by a chain or cable and released downhill. The potential energy accumulated by
1650-518: Is the most common method of stopping a roller coaster train as it returns to the station. One notable exception is a powered roller coaster , which instead of relying on gravity uses one or more motors to propel the trains along the course. In 2006, NASA announced that it would build a system using principles similar to those of a roller coaster to help astronauts escape the Ares I launch pad in an emergency, although this has since been scrapped along with
1716-401: Is usually pulled by a chain. The pawl moves over bumps that are separated closely apart. In the event that the train ever becomes disconnected from the chain, the anti roll-back system will engage and it will fall back into the nearest downhill stop preventing the train from falling down the lift hill. Another key to safety is the programmable logic controller (PLC), an essential component of
1782-706: The Catherine Park . Two roller-coasters were built in France in 1817. Les Montagnes de Belleville ( Les Montagnes Russes à Belleville ) in Belleville, Paris had wheels attached to carriages and locked on tracks. The Promenades Aériennes , opened in Parc Beaujon in Paris on July 8, 1817 had wheeled cars securely locked to the track, guide rails to keep them on course, and higher speeds. It spawned half
1848-499: The kiddie coaster , is a roller coaster specifically designed for younger riders. Following World War II, parks began pushing for more of them to be built in contrast to the height and age restrictions of standard designs at the time. Companies like Philadelphia Toboggan Company (PTC) developed scaled-down versions of their larger models to accommodate the demand. These typically featured lift hills smaller than 25 feet (7.6 m), and still do today. The rise of kiddie coasters soon led to
1914-525: The 1967 Iowa State Fair . It featured 16 cars with two passengers per car. The first park model, an 80-foot Giant Wheel, was built in 1975 at Valleyfair amusement park in Minnesota. It features 18 cars holding four passengers per car and is still in operation. The Giant Wheel/Century Wheel was introduced in various sizes in both park and portable models in 1988. In 2006, Chance worked with Ronald Bussink Professional Rides of Switzerland and Dutch Wheels BV,
1980-542: The Big Dipper children's coaster. With the integration of the D. H. Morgan line into Chance Rides in 2001, the company acquired track manufacturing technology and the ability to offer a variety of coaster designs. D. H. Morgan was an offshoot of Arrow Development , original developer of tubular steel track, first used on Disney's Matterhorn Bobsleds attraction. In 2006, Chance formed an alliance with Vekoma . Chance Rides represented Vekoma in North America and manufactured
2046-579: The Golden Age. This aside, roller coasters were still built with varying success from location to location. In May 1932, the Scene Railway witnessed somewhat of a revival in the UK, including the opening of the roller coaster at Great Yarmouth . Today it is one of only two scenic railways still in operation in the UK. In 1959, Disneyland introduced a design breakthrough with Matterhorn Bobsleds ,

2112-500: The Netherlands to Appenzell Innerrhoden , Switzerland . It was then known as Ronald Bussink Professional Rides, a registered trademark of Ronald Bussink Aktiengesellschaft, which was subsequently renamed Professional Rides Aktiengesellschaft, RoBu Privat Equity AG and then RoBu AG. In 2008, following the sale of Bussink's Wheels of Excellence range to Vekoma , Bussink created a new company, Bussink Landmarks, to concentrate on
2178-619: The R40, R50, and R60 models. Following the sale of the Wheels of Excellence range, Bussink founded a new company, Bussink Landmarks, to concentrate on the supply of giant observation wheels of 100 metres (328 ft) and greater in height. Bussink also founded, and is CEO of, Bussink Design. He designed the R80XL , which is manufactured and sold under licence from Bussink Design GmbH by Maurer German Wheels and Chance American Wheels . The R80XL
2244-662: The S-24 Iron Horse train ceased. Locomotives and coaches can be customized in a variety of ways. Chance Carrousels (deliberately spelled with two "R"s) were introduced in 1971 following the acquisition of the Allan Herschell Company the previous year. Chance modified the Herschell design giving it a more ornate style. After Chance purchased Bradley & Kaye in December 1986, Chance was able to use
2310-435: The ability to invert riders. A third classification type is often referred to as a hybrid roller coaster , which utilize a mixture of wood and steel elements for the track and structure. Many, for example, have a track made out of steel and a support structure made from wood. RMC has notably redesigned wood coasters that have either deteriorated from age or been deemed by parks as too costly to maintain. RMC often replaces
2376-574: The amusement business since 1946, building small trains for the Ottaway Amusement Company. He designed a 2 ft ( 610 mm ) narrow gauge replica of the C. P. Huntington , a well-known steam locomotive built in 1863 for the Central Pacific Railroad . Titled by the same name, Chance's C. P. Huntington is the company's most successful product line. In 1967, Chance began producing Starliner Trams under
2442-411: The banking of curves. Wheels are a critical part in rollercoaster design. The purpose of wheels is to keep the train on the track and to prevent it from flying off. A majority of roller coaster wheels are made from polyurethane. There are 3 kinds of roller coaster wheels which include road wheels, side friction wheels, and up-stop wheels. Road wheels ride on top of the track. Side friction wheels ride on
2508-819: The brand Chance Morgan . In 2011, the company reintroduced the Chance Rides brand which encompasses Chance Morgan Coasters, Inc. and Chance Rides Manufacturing. On September 17, 2011, trade publication Amusement Today presented Chance Rides with the Golden Ticket Award for Supplier of the Year, in honor of the company's 50th anniversary. In 2023, Chance Rides was sold to Missouri-based private equity firm Permanent Equity. Chance Rides began to fabricate their 2 ft narrow gauge C. P. Huntington locomotive in 1961. These locomotives can be powered by gasoline, diesel, propane or electric engines; as of 2024, only
2574-547: The development of "junior" models that had lift hills up to 45 feet (14 m). A notable example of a junior coaster is the Sea Dragon – the oldest operating roller coaster from PTC's legendary designer John Allen – which opened at Wyandot Lake in 1956 near Powell, Ohio. A hypercoaster , occasionally stylized as hyper coaster, is a type of roller coaster with a height or drop of at least 200 feet (61 m). Moonsault Scramble , which debuted at Fuji-Q Highland in 1984,
2640-491: The electric model is being offered. Its drive wheels are not powered, but roll on the rails while fake side rods reciprocate in and out of fake cylinders . Power is instead provided by the front and rear trucks . With more than 400 examples built as of 2022, the C. P. Huntington has become the most popular park train since the Allan Herschell Company merged into Chance Industries in 1970 and production of
2706-416: The experience involve removing the floor beneath passengers riding above the track, as featured in floorless roller coasters . Unique track elements, such as new inversions, are often introduced to provide entirely new experiences. Several height classifications have been used by parks and manufacturers in marketing their roller coasters, as well as enthusiasts within the industry. One classification,

2772-503: The first full-circuit coaster with a lift hill , the Gravity Pleasure Road , which became the most popular attraction at Coney Island. Not to be outdone, in 1886 Thompson patented his design of roller coaster that included dark tunnels with painted scenery. "Scenic railways" were soon found in amusement parks across the county. By 1919, the first underfriction roller coaster had been developed by John Miller . Over
2838-432: The first permanent roller coaster to use a tubular steel track. Designed by Arrow Development , the tubular track was unlike standard rail design on wooden coasters, allowing the track to bend in sharper angles in any direction, leading to the incorporation of loops, corkscrews, and inversion elements into track layouts. A little more than a decade later, the immediate success of The Racer at Kings Island in 1972 sparked
2904-576: The first to use the term "roller coaster". The term jet coaster is used for roller coasters in Japan, where such amusement park rides are very popular. In many languages, including most Romance languages, the name refers to "Russian mountains". Conversely, in Russian, they are called "Американские горки" ( Amerikanskiye gorki , "American hills"). In the Scandinavian languages , the roller coaster
2970-485: The labour and expense in cost, as well as the vast quantity of wood used in it. At the same place, there is another artificial mount which goes in a spiral line, and in my opinion, for I have tried it also, is very disagreable; as it seems always leaning on one side, and the person feels in danger of falling out of seat. Katalnaya gora was dismantled in 1792–1795. Currently in its place is the Granite Terrace in
3036-472: The late 1980s. With the merger of the D. H. Morgan line of carousels, some of the unique Morgan figures have been added to the collection as well. Although fiberglass, the magnificent detail and menagerie of different styles of horses and other figures have become a trademark of Chance Rides carrousels. The first Ferris wheel from Chance, the Astro Wheel, was sold to showman Don Franklin and debuted at
3102-455: The molds and manufacturing rights to 62 carousel figures produced by Bradley & Kaye owner, David Bradley. He had carefully reproduced prized carousel animals from famous carvers over the previous 20 years and new molds were cast at the Chance facility under his direction, until Bradley died in 1988. These famous reproductions with spectacular detail have been included on Chance carrousels since
3168-474: The name endured. Another explanation is that the phrase originated from a ride located in a roller skating rink in Haverhill , Massachusetts in 1887. A toboggan -like sled was raised to the top of a track which consisted of hundreds of rollers. This Roller Toboggan then took off down gently rolling hills to the floor. The inventors of this ride, Stephen E. Jackman and Byron B. Floyd, claim that they were
3234-491: The next decade, roller coasters spread to amusement parks around the world and began an era in the industry often referred to as the "Golden Age". One of the most well known from the period is the historical Cyclone that opened at Coney Island in 1927. The onset of the Great Depression in the 1930s, however, significantly impacted the amusement park industry and brought an end to the rapid growth experienced during
3300-430: The range of 4–6 Gs (40–60 m s ) as a maximum for positive g-force acceleration, which increases the feeling of weight and pushes riders downward into their seat. For negative g-force, or the feeling of weightlessness, the target is 1.5–2Gs (15–20 m s ) as a maximum. These fall into a range considered safe to a majority of the population. Lateral acceleration is also typically kept under 2Gs using various techniques including
3366-463: The rest of the Ares program . Some sources have shown concern over the ability of roller coasters to cause head trauma and serious injury such as the tearing of axons and damaging of blood vessels. A variety of safety mechanisms protect riders on roller coasters. One of these is the block system . Most large roller coasters have the ability to run two or more trains at once, and the block system prevents these trains from colliding. In this system,
SECTION 50
#17328024124313432-466: The rise in height is transferred to kinetic energy , which is then converted back into potential energy as the train rises up the next hill. Changes in elevation become smaller throughout the track's course, as some mechanical energy is lost to friction and air drag . A properly-designed, outdoor track will result in a train having enough kinetic energy to complete the entire course under a variety of stressful weather conditions. Not all coasters feature
3498-432: The same tower. The ride was invented by Walter House of Amarillo, Texas, and Chance acquired the manufacturing rights and started producing it in 1969. It was designed to be a carnival ride, fitting on two trailers, but several units were purchased by amusement parks where they were set up as permanent attractions. Chance manufactured 32 of these units, two of which still operate at a permanent park. In 1998 Chance introduced
3564-456: The side of the track to keep the train on the track throughout turns. Up-stop wheels ride below the track and prevent the train from lifting off the track. Roller coasters are statistically very safe when compared to other activities, but despite all the safety measures in place, accidents still occur. The International Association of Amusement Parks and Attractions (IAAPA) reports that a rider has one chance in 15.5 million of being injured on
3630-480: The steel track for select projects. On October 17, 2012 Chance Rides and Vekoma discontinued their agreement to produce rides together for the North American market. As of 2023, Chance Rides has built 44 roller coasters around the world. Roller coaster Tracks are typically built and designed as a complete circuit in which trains depart from and return to the same loading station . One variation,
3696-496: The subsidiary Chance Coach. In 1970, Chance acquired the assets of the Allan Herschell Company . Richard G. Chance (Dick Chance) assumed control of the company and formed Chance Industries, Inc. in 1985 to oversee the various divisions – Chance Rides, Chance Coach, and Chance Operations. In December 1986, Chance then acquired Bradley & Kaye, a ride manufacturer specialized in children's rides and carousel figures. For several years, Chance Rides Manufacturing products were sold under
3762-425: The supply of observation wheels of 100 metres (328 ft) and greater in height. The Wheels of Excellence range included the following models: In 2008, the Wheels of Excellence range of giant wheels was acquired by Vekoma Rides Manufacturing . Vekoma created a new division, Dutch Wheels BV, to market giant wheels as stand alone attractions. As of 2012, Wheels of Excellence variants listed by Dutch Wheels BV were
3828-441: The tallest roller coaster in the world. Bussink Design GmbH Ronald A. Bussink has been a leading designer of giant Ferris wheels and similar structures for over 25 years. Bussink entered the amusement industry market in 1985 and designed, manufactured, and delivered more than 60 giant observation wheels between 1990 and 2005. The Bussink company was previously known as Nauta Bussink prior to moving its offices from
3894-412: The term strata was first introduced by Cedar Point with the release of Top Thrill Dragster, a 420-foot-tall (130 m) roller coaster that opened in 2003. Kingda Ka was the second strata coaster, and it opened at Six Flags Great Adventure in 2005 as the tallest roller coaster in the world with a height of 456 feet (139 m). Top Thrill Dragster closed in 2021 following a serious incident in which
3960-410: The track is divided into two or more sections known as blocks. Only one train is permitted in each block at any given time. There is a section of track at the end of each block where a train can be stopped if necessary, such as preventing dispatch from the station, stopping a lift, or applying brakes. Sensors detect when a train passes so that the system's computer is aware of which blocks are occupied. If
4026-409: The wood track with their patented steel I-Box track design, while reusing much of the ride's wooden structure, resulting in a smoother ride with the incorporation of new design elements, such as inversions, sharper turns, and steeper drops. Although the term wasn't widely used or accepted until the 21st century, one of the oldest examples is Cyclone at Luna Park , which opened in 1927. It features
SECTION 60
#17328024124314092-485: Was coined during the construction of the Millennium Force , a roller coaster built by Intamin on Cedar Point amusement park. Although Morgan and Bolliger & Mabillard have not used the term giga , both have also produced roller coasters in this class. A strata coaster is a type of roller coaster with a height or drop of at least 400 feet (120 m). As with the other two height classifications,
4158-415: Was engineered by Russian scientist Andrey Nartov . The Anglican clergyman John Glen King mentioned that some Englishmen visiting Russia called them "Flying Mountains" and described them as follows: You will observe that there are five mounts of unequal height: the first and the highest is full thirty feet perpendicular altitude; the momentum with which they descend this carries them over the second, which
4224-419: Was known as Katalnaya gora (Катальная гора, literally "Mountain for riding") It was a huge building in the shape of rotunda . It had a trail with five hills which can be covered with ice in winter. In the summer time the trails used trolleys on wheels secured in the steel grooves mounted on the wooden trails. Due to a pendulum-like motion based on inertia all five hills could be traversed in one ride. The ride
4290-596: Was the Capital Wheel at the National Harbor , Md. It opened May 23, 2014. Chance Rides/Chance American Wheels will continue to manufacturer and sell R60 wheels in North America under an exclusive license from Dutch Wheels BV. Notable wheels include: Chance Manufacturing's first coaster was the Toboggan, a portable ride in which a small vehicle climbed vertically up a tower then spiraled back down around
4356-438: Was the first to break this barrier, though the term hypercoaster was first coined by Cedar Point and Arrow Dynamics with the opening of Magnum XL-200 in 1989. Hypercoasters have become one of the most predominant types of roller coasters in the world, now led by manufacturers Bolliger & Mabillard and Intamin . A giga coaster is a type of roller coaster with a height or drop of at least 300 feet (91 m). The term
