A Ride into History Today, the Disneyland Monorail is comprised of the Red, Blue and Orange Mark VII trains. Because the system uses a 600-volt DC power source, it emits no direct exhaust or pollutants into the atmosphere.

The Walt Disney World and Disneyland monorails are entirely electrically powered. They operate using a 600-volt DC (Direct Current) propulsion system. Each train picks up electricity from a metallic "bus bar" (an electrified rail) that runs along the side of the concrete beamway. This electricity is then fed to high-efficiency traction motors located in the train's power cars. For example, a Mark VI monorail at Disney World has eight DC motors, each producing roughly 113 horsepower, which drive the rubber tires that straddle the beam. The system is designed to be eco-friendly and exceptionally quiet, which is why you only hear a slight "whirring" sound as it passes. In 2026, Disney has continued to upgrade the power management systems to be more energy-efficient, integrating some power from the resort’s massive solar farms. Despite the futuristic appearance, the fundamental technology—using an electrified third rail similar to a subway system—has remained the core power source since the system first debuted, allowing the "Highway in the Sky" to move over 150,000 guests a day without on-board fuel or heavy engines.
