How Escalator Steps Stay Level: The Hidden Dual-Track System

Ever wondered how flat escalator steps seamlessly transform into stairs and back again? This episode of Hidden Mechanics explores the ingenious engineering that keeps passengers level during the ride. Discover how a rigid metal wedge equipped with four wheels and two independent, parallel guide tracks controls the entire transition from slope to landing. Learn why steps never compress or detach, how they flip upside down on the return trip, and the physical geometry that makes this everyday transit reliable and safe. #HiddenMechanics #Engineering #Design #Physics
