A dual-tracked roller coaster is a roller coaster which consists of two tracks. There are three types of dual-tracked roller coasters: racing, dueling, and Möbius Loop roller coasters.
A racing roller coaster consists of two separate roller coasters that travel along parallel or mirrored tracks to simulate a race between the trains. The coaster trains travel along tracks just a few feet apart from one another. They often get close enough for riders to reach out and slap hands with riders on the opposite train, though this is extremely dangerous and can result in ejection from the park.
A dueling roller coaster features two (or more) roller coasters, usually with a similar layout, built close to each other. The rides are designed to do just as the name indicates: to duel. The coaster's layout often consists of strategic maneuvering to produce near-misses between the two coaster trains, designed to induce a greater adrenaline rush for the rider than a stand-alone roller coaster.
A Möbius loop roller coaster can be either a racing roller coaster or a dueling roller coaster. Its unique feature is that there is one continuous track instead of two separate ones. As a result, the station that a train leaves is not the same one to which it will return. One unusual case is Twisted Colossus at Six Flags Magic Mountain, a Möbius Loop type coaster where there is only one station - one cycle of the ride takes the train through both sides of the "Möbius Loop."
