Abstract

An elevator system includes at least two independently operable elevator cars in each elevator shaft of the system. The elevator shaft may include a first and a second region, with the first region extending from a ground level to sub-ground levels, and with the second region extending from the ground level to a top floor. A first elevator car may move within the first region and a second elevator car may move within the second region, in the same shaft independently of each other.
