Roller coaster train

El Toro (2006), a wooden roller coaster at Six Flags Great Adventure in New Jersey, uses traditional lap restraint trains.

A roller coaster train is a vehicle made up of two or more carts 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. 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]
