A moving stairway, also known as an escalator, is a mechanical device that transports people vertically between floors using a continuous loop of steps. It's essentially a mechanized staircase, making it easier to traverse between levels in buildings. Think of it as a bridge between floors that walks for you. Unlike stairs, it doesn't require effort, and unlike elevators, it offers a continuous flow of people. They're super common in malls, airports, and subway stations.
