Each train is 203 ft 6 in (62.03 m) long (consisting of six cars) and can carry 360 passengers. The trains are driven by eight 113 hp (84 kW) motors which are powered by a 600-volt electrical system running through a busbar mounted on each side of the concrete beam.

The Disney Monorail System is a high-capacity "straddle-beam" monorail, meaning the train sits on top of a single, narrow concrete beam rather than hanging from it. In 2026, the Mark VI trains used at Walt Disney World operate using direct current (DC) electricity drawn from a "bus bar" running along the side of the beam, providing 600 volts to the motors. Each train car features rubber tires that grip the top of the beam for support and smaller horizontal tires that "pinch" the sides for stability and guidance. While the system was originally manual, it has been heavily modernized with an Automated Train Control (ATC) system that uses sensors to maintain safe distances between trains and control speeds, although a "pilot" remains in the front cab for safety monitoring and guest interaction. The concrete beams are hollow and specifically engineered to allow for slight thermal expansion without affecting the smoothness of the ride. This combination of 1950s "futurism" and modern safety technology allows the system to move over 150,000 guests daily across nearly 15 miles of track, functioning as a vital "highway in the sky" for the resort.
