Polarity is an unmanned rapid transport system using magnetic forces to propel the train forward at great speed. It has a unique and flexible track system with a futuristic feel. It was released with the World's Fair Pack DLC.
Polarity is based on the PeopleMover and Tomorrowland Transit Authority PeopleMover attractions at Disneyland and Walt Disney World's Magic Kingdom, respectively. Its open-top vehicles and linear induction propulsion are based on the Magic Kingdom version of the attraction, while its Y-frame track supports are based on that of the Disneyland version.
