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

Blackbeard's Lost Treasure Train (1999) at Six Flags Great Adventure has trains composed of 20 cars.
An inverted roller coaster is a type of steel roller coaster in which the train runs under the track with the seats directly attached to the wheel carriage. Riders are seated in open cars, letting their feet swing freely. The inverted coaster was pioneered by Swiss roller coaster manufacturer Bolliger & Mabillard in the early 1990s with the development of Batman: The Ride, which opened at Six Flags Great America on May 9, 1992.
