Roller coaster train comprised of 5 cars.

A roller coaster train describes the vehicle(s) which transports passengers around a roller coaster's circuit. More specifically, a roller coaster train is made up of two or more "cars" which are connected by some sort of specialized joint. It is called a "train" due to its resemblance of a locomotive where multiple units (cars) are joined together and act as one entity. Individial cars often vary in design and can carry anywhere from one to eight or more passengers each. Download high resolution version (579x800, 60 KB)Train of Mr. ...

Basic safety features

Roller coaster wheels

Roller coaster trains have wheels that run on the sides (side friction wheels) and underneath the track (upstop wheels) as well as on top of it, these lock the train to the tracks and prevent it from flying off. 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. Restraints are of two major types, lapbar and over-the-shoulder.

Lapbar 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. Lapbar restraints give the rider much greater freedom of movement than over-the-shoulder restraints, enhancing the feeling of danger. However, lapbar restraints are not quite as safe as over-the-shoulder restraints, as evidenced by several accidents. Some roller coasters have had their lapbar restraints replaced with over-the-shoulder restraints. Others have had shoulder restaints replaced with lap bar restraints, allowing for a more comfortable ride. Some roller coasters (usually wooden roller coasters) also include seatbelts in addition to a lap bar. Roller coaster inversions are features of roller coasters that in some form or fashion, inverts (turns upside-down) its riders. ... Anton Schwarzkopf (1924-2001) was a prolific German roller coaster engineer and founder of the Schwarzkopf Industries company, which built numerous amusement park rides and roller coasters. ...

An inverted roller coaster car with over-the-shoulder restraints

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. Almost all roller coasters that have inversions have this type of restraint. Additionally, all Inverted roller coasters and Floorless roller coasters have this type of restraint, as there is simply no place to mount a lapbar 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 such as some rides made by Vekoma.

However, there is one operating roller coaster that does not have either of these safety features: Leap-The-Dips, the world's oldest operating roller coaster and North America's last surviving side friction roller coaster. As a side friction coaster, it does not have wheels under the track. Rather, it runs in a trough with wheels that run along the sides of the trough to keep the train in place. Additionally, Leap-The-Dips simply does not require restraints as it is only 41 ft (12.5 m) high and has an average speed of only 10 mph (16 km/h). Until early 2006, the Rollercoaster at Blackpool Pleasure Beach in the UK also operated without any restaints, although seatbelts were recently added to the ride.

Physics

In general, 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. In classical mechanics, momentum (pl. ...
