Abstract
A passenger transport installation in which a large number of people can be efficiently transported between at least two vertically-spaced places. Stations communicate with a vertical elevator passage or passages along which vehicles can move upward and downward, and the vehicles stop at the stations to allow passagers to get on and off. While passengers get on and off the vehicles at the stations, other vehicles carrying other passengers can move upward and downwardly along the elevator passage or passages.
