The Omnimover system consists of a chain of vehicles operating on a track, usually hidden beneath the floor. The chain of vehicles maintains constant motion at a specific speed throughout the entire course of the attraction. To facilitate boarding and disembarking from the vehicles, a conveyor belt moving the same speed as the ride vehicles parallels the track at the loading and unloading areas. Passengers step from the moving belt into the vehicle or vice versa.
One of the defining features that differentiates this system from other ride systems is the ability of the vehicle to rotate to a predetermined orientation. Aside from the rails the vehicle rides on, the Omnimover system has two control rails that are connected to the vehicle via arms attached to a wheel that follows one of the control rails. One control rail controls the swivel of the vehicle, allowing the vehicle to be pointed to a specific direction at a specified location on the track. The other control rail adjusts the tilt of the vehicle allowing it to stay level even as the main track ascends or descends inclines.
The Omnimover system was created by Roger E. Broggie and Bert Brundage to provide a ride system capable of giving passengers a motion picture type experience in which the attraction designers control the line of sight of the riders. This concept also allows the designers to be able to place infrastructure elements of the attraction, such as lighting and projectors, behind the vehicles without concern for having the illusions of the attraction revealed to the riders.
