A moving staircase that taught crowds to flow upward.
Why it matters
The escalator moves people continuously between floors, making vertical circulation feel like a walkway instead of a trip.
Quick answer
A moving staircase that taught crowds to flow upward. Learn the origin, mechanics, timeline, and design details behind the escalator.
How it works
Linked steps move on tracks. Each step stays level on the visible incline, then folds back underneath for the return loop.
