Early escalators were designed to operate in one direction only, either up or down, and it was not possible to reverse the direction of the escala- tor. Later designs included the esca- lator to be reversible in that the direction of travel could be reversed from up to down direction or vice- versa.
Are escalators reversible?
While escalators and moving walks can reverse their direction, and it would seem like a good measure to do so, it is not a common practice. The design of the area or building where the escalator or moving walk is located in and the flow of human traffic also determine whether a direction reversal is suitable.
