Abstract
An external elevator system piggy backs a first rail car on a second rail car to permit simple and rapid transfer of the first rail car to an upper setback section of a high-rise building. Each rail car is equipped with pinion drives that engage racks fixed to vertical rails that are attached to the faces of the base section and setback section of the buildings. The cars also have motor driven wheels that allow the car to drive on horizontal surfaces.
