Where Do Escalator Steps Go? Inside the Hidden Loop

Every disappearing escalator step is still moving. Open the side of the machine and follow the same rigid steps through the landings, upper turnaround, hidden return and lower station. See how the chain supplies the pull, the roller tracks control the angle, and the handrail follows its own loop.
