The inter-terminal train is the only WEDway people mover built by the Walt Disney Company outside of a Disney property. It uses much of the mechanical technology used by the Tomorrowland Transit Authority PeopleMover, an attraction in the Magic Kingdom's Tomorrowland. The design permits the trains to make tight corners that are necessary along portions of the basement route, and is unusual in that on-train station announcements and audible warning messages are actually provided by a trackside audio system through openings in the tops of the vehicle carbodies. The train operates in a circuit, stopping at every terminal as well as the Houston Airport Hotel before returning to its starting point.
The system is presently maintained and operated by Johnson Controls.
