An escalator is a conveyor transport device to transport people, consisting of a staircase whose steps move up or down on tracks which keep them horizontal. Most escalators also have moving handrails which approximately keep pace with the movement of the steps. The direction of movement (up or down) can be permanently the same, or be controlled by personnel according to the time of day, or automatically be controlled by whoever arrives first, someone at the bottom or at the top (of course the system is programmed such that the direction is not reversed while somebody is on the escalator). In the last two cases there has to be an alternative nearby.

Escalators are typically used in pairs with one going up and the other going down. Some modern escalators in stores and shopping malls have glass sides which allow their workings to be viewed. Although most escalators are straight, some shopping malls use curved versions.
