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).

Basic safety features


Roller coaster wheels Roller coaster wheels.jpg
Roller coaster wheels

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.


At a given velocity, the longer a roller coaster train becomes, the more momentum it gains throughout the ride's course. A roller coaster train that is fully loaded will also have more momentum than one that is empty or nearly empty.

Mindbender (Galaxyland)

The Mindbender is an Anton Schwarzkopf looping roller coaster opened in 1985 at Galaxyland Amusement Park, a theme park located in West Edmonton Mall, in Alberta, Canada. At 44.2 m (145 ft) in height, it is the tallest indoor roller coaster in the world as of 2020.

Corkscrew (Cedar Point)

Corkscrew is a steel roller coaster built by Arrow Development at Cedar Point in Sandusky, Ohio, United States. When 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 Great American 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.

<i>Superman: Ultimate Flight</i>

Superman: Ultimate Flight is a steel flying roller coaster designed by Bolliger & Mabillard. Themed to the popular comic book character, Superman: Ultimate Flight has been installed at three Six Flags theme parks around the United States: Six Flags Over Georgia, Six Flags Great Adventure and Six Flags Great America. 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.

Accelerator 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.

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.

Suspended Family Coaster

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

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.

Roller coaster elements are the individual parts of roller coaster design and operation, such as a track, hill, loop, or turn. Variations in normal track movement that add thrill or excitement to the ride are often called "thrill elements".


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 de 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 de Zeus, OzIris and Trace du Hourra rollercoasters.
