A roller coaster train is a vehicle made up of two or more cars connected by specialized joints which transports passengers around a roller coaster's circuit. Roller coasters usually have various safety features, including specialized wheels and restraints.
A roller coaster train is a vehicle made up of two or more cars connected by specialized joints which transports passengers around a roller coaster's circuit. It is called a train because the cars follow one another around the track, the same reason as for a railroad train. Individual cars vary in design and can carry from one to eight or more passengers each.[ citation needed ]
Many roller coasters operate more than one train, sometimes several, simultaneously. Typically they operate two trains at a time, with one train loading and unloading while the other train runs the course. On the Rock 'n' Roller Coaster at Walt Disney World, for example, there are five trains, but only four operate at a time (the trains are rotated out on a regular basis for safety reasons).
Roller coaster trains have wheels that run on the sides (side friction or guide wheels) and underneath the track (upstop, underfriction, or underlocking wheels) as well as on top of it (road or running wheels); these lock the train to the tracks and prevent it from jumping the track. The side wheels can be mounted on the outside or inside of the train, depending on the manufacturer (although outside-mounted wheels are more common). The wheels are sometimes located between the cars, as well as at the front and rear of the entire train.
Roller coaster trains also have restraints that keep the passengers in their seats. There are two major types of restraints: lap bar and over-the-shoulder. (Most modern over-the-shoulder restraints come into contact with riders at the lap; however, older so-called "horsecollar" ones actually restrain riders by the shoulders). Restraints always use two locking mechanisms, one on each side, for redundancy. If one fails, the restraint will remain locked. Most modern roller coasters also have seat belts that may act as secondary safety devices. On over-the-shoulder restraints, this seatbelt is mostly cosmetic as the restraint locks on its own.
Lap bars were first used in 1907 with the Coney Island coaster Drop the Dip. [1] Lap bar restraints consist of a padded bar mounted to the floor or side of the train that swings backwards into the rider's lap. These restraints are usually found on roller coasters that lack inversions. Some inverting roller coasters, notably ones created by Anton Schwarzkopf safely operate without the need for shoulder restraints. Historically, inverting roller coasters with lap bars could only perform vertical loops, as the higher centripetal force (and low lateral force) exerted while traversing a simple clothoid loop helps to keep riders safely in the train. However, with modern advances in engineering, more roller coasters with complicated inversions are able to run without over-the-shoulder restraints. For example, most of Premier Rides' LIM-launched roller coasters (the vast majority of which have multiple inverting elements) operate with only lap bars. Lap bar restraints, like buzz bars give the rider much greater freedom of movement than over-the-shoulder restraints, enhancing the feeling of danger for some.
Over-the-shoulder restraints, the most common type, consist of a roughly U-shaped padded bar mounted to the top of each seat that swings downward. Roller coasters that have inversions usually have this type of restraint. Additionally, almost all inverted and floorless roller coasters have this type of restraint, since it is difficult to mount a lap bar restraint. One disadvantage of over-the-shoulder restraints is that they can provide discomfort to the rider (known among coaster enthusiasts as headbanging), especially on rougher roller coasters. It is recommended that earrings should be removed before riding roller coasters with over-the-shoulder restraints. Some rides, such as Maverick at Cedar Point, require that guests must remove earrings before riding.
However, there are some operating roller coasters that do not have either restraint systems. Rollo Coaster at Idlewild and Soakzone is a good example of this. Usually roller coasters with little to no air-time (being lifted out of your seat) do not have restraints. Until early 2006, The Rollercoaster at Blackpool Pleasure Beach in the UK also operated without any restraints, although seatbelts were added to the ride in the 2007 season. During 2008, trains from the Big Dipper Rollercoaster were installed on the ride. "The Rollercoaster" now operates with lap bars, although the original train is still stored on the transfer track in the station.
A roller coaster, or rollercoaster, is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. Passengers ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island. The track in a coaster design does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably Wild Mouse roller coasters, run with single cars.
An inverted roller coaster is a roller coaster in which the train runs under the track with the seats directly attached to the wheel carriage. This latter attribute is what sets it apart from the older suspended coaster, which runs under the track, but swings via a pivoting bar attached to the wheel carriage. The coaster type's inverted orientation, where the passengers' legs are exposed, distinguishes it from a traditional roller coaster, where only the passengers' upper body parts, including the arms, are exposed.
A stand-up roller coaster is a roller coaster designed to have the passengers stand through the course of the ride.
A flying roller coaster is a type of roller coaster meant to simulate the sensations of flight by harnessing riders in a prone position during the duration of the ride. The roller coaster cars are suspended below the track, with riders secured such that their backs are parallel to the track.
The Mindbender was an Anton Schwarzkopf looping roller coaster at Galaxyland, a theme park in West Edmonton Mall, in Alberta, Canada. The ride officially opened to the public on December 20, 1985 at a cost of $6 million. At 44.2 m (145 ft) in height, it was the tallest indoor roller coaster in the world as of 2020.
Corkscrew is a steel roller coaster built by Arrow Development at Cedar Point in Sandusky, Ohio, United States. Built in 1976, it was the first roller coaster in the world with 3 inversions. The coaster, which features Arrow's first vertical loop, was built during the same time period as The New Revolution at Magic Mountain. However, Revolution opened seven days prior and is therefore credited as the first modern-day coaster to feature a vertical loop.
Batman & Robin: The Chiller was a dual-tracked, launched roller coaster located at Six Flags Great Adventure in Jackson Township, New Jersey. Designed by Premier Rides, the ride was themed to the Batman & Robin movie. It opened to the public on June 7, 1997, but after a series of setbacks shortly after its debut, the roller coaster closed for much of its inaugural season and didn't reopen until 1998. When it did, ride operation was changed to launch only one side at a time as a result of the amount of power required by the ride's linear induction motor (LIM) launch system. Although modifications were made over the years to improve the ride experience and limit the amount of downtime, the park decided to remove the attraction following the 2007 season.
Superman: Ultimate Flight is the name of three flying roller coasters currently operating at three Six Flags amusement parks in the United States, those being Six Flags Over Georgia, Six Flags Great Adventure and Six Flags Great America. Each of these steel coasters were designed and built by Swiss manufacturer Bolliger & Mabillard and opened in 2002 and 2003. Since 2003, Six Flags has installed Superman: Ultimate Flight in three of their parks. Themed to the popular comic book character, Superman: Ultimate Flight simulates flying by positioning its passengers parallel to the track, supported by harnesses and facing the ground through most of the ride. In the station, riders board the train sitting down. After the train is locked and checked, the trains are raised into the flying position. After the ride, the seats are lowered back into the sitting position for the next round of riders.
The Suspended Looping Coaster is a model of steel inverted roller coaster built by Vekoma. There are at least 39 different installations across the world. The minimum rider height requirement is 130 centimetres. Vekoma is now marketing a Suspended Thrill Coaster as a successor to the Suspended Looping Coaster. The Odyssey is the largest, fastest and tallest SLC ever built at Fantasy Island in the UK.
Xcelerator is a steel launched roller coaster at Knott's Berry Farm in Buena Park, California. It was Intamin's first hydraulically launched coaster, while also the fourth Intamin installation at Knott's, alongside Sky Cabin, Calico River Rapids and Perilous Plunge.
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.
Phantom's Revenge is a steel hypercoaster located at Kennywood amusement park in West Mifflin, Pennsylvania, United States. It originally opened as Steel Phantom in 1991, featuring the fastest speed and longest drop of any roller coaster in the world. Its second drop is longer than its first, which is a unique characteristic among roller coasters. Manufactured by Arrow Dynamics, the ride was later modified and renovated by D.H. Morgan Manufacturing for the 2001 season when it reopened as Phantom's Revenge. The drop and track length were both increased, and its four inversions were removed, allowing the removal of its uncomfortable over-the-shoulder restraints.
The Tower of Terror II was a steel shuttle roller coaster located at the Dreamworld amusement park on the Gold Coast, Queensland, Australia. When the Tower of Terror opened on 23 January 1997, it was the first roller coaster in the world to reach 100 miles per hour (160 km/h), making it the tallest and fastest roller coaster in the world of its time. The ride was situated on the Dreamworld Tower, which also houses The Giant Drop free fall ride. The ride was originally known as the Tower of Terror until it was modified and relaunched in September 2010 as Tower of Terror II.
Flight Deck is a steel inverted roller coaster located at Canada's Wonderland in Vaughan, Ontario, Canada. It originally opened in 1995 under the name Top Gun until it was renamed in 2008 to Flight Deck, after Paramount Parks sold Wonderland to Cedar Fair which necessitated the gradual removal of all Paramount names and trademarks from the theme park.
A Suspended Family Coaster is a steel inverted roller coaster built by Vekoma designed for families with no inversions. Just like all inverted roller coasters the train runs under the track with the seats directly attached to the wheel carriage. This latter attribute is what sets it apart from the older suspended swinging coaster, which runs under the track, but "swings" via a pivoting bar attached to the wheel carriage.
Le Monstre is a wooden roller coaster at La Ronde amusement park in Montreal, Quebec, Canada. Le Monstre is the largest wooden roller coaster in Canada and is also the tallest two-track wooden roller coaster in the world.
Goudurix is a steel roller coaster located in Parc Astérix in France. The Vekoma-built ride jointly held the European record for the greatest number of inversions upon its opening in 1989. The record was lost in 1995 to Dragon Khan in Spain. It is one of only two coasters in the world to feature a butterfly element. In 2007, following the release of the animated movie Asterix and the Vikings, Viking theming was added to the station and nearby rides, in the form of a wooden Viking longboat. Goudurix is located in the back-west of the park, near the Tonnerre 2 Zeus. The ride was repainted to a yellow and red track with grey supports color scheme from its previous white and yellow track with blue supports. It is one of the park's main attractions, along with the Tonnerre 2 Zeus, OzIris and Trace du Hourra rollercoasters.
The Odyssey is a roller coaster at Fantasy Island in Ingoldmells, England. Built by Vekoma of the Netherlands in 2002, it was named to commemorate the Golden Jubilee of Queen Elizabeth II. It is Vekoma's tallest example of their Suspended Looping Coaster (SLC) design in the world. Standing at 167 feet, it is the third tallest roller coaster in the UK, after the Pepsi Max Big One and Stealth. And the joint second tallest full circuit inverted rollercoaster in the world. It has a maximum speed of 63 mph and is capable of forces up to 4.8g.
The physics of roller coasters comprises the mechanics that affect the design and operation of roller coasters, a machine that uses gravity and inertia to send a train of cars along a winding track. Gravity, inertia, g-forces, and centripetal acceleration give riders constantly changing forces which create certain sensations as the coaster travels around the track.
