Abstract
An elevator system that may be ropeless is in a structure and includes a guide rail and a guide rail extension that may generally guide a car between a hoistway and a transfer station of the system. The rail extension may generally project telescopically downward from the first rail and toward the transfer station. The telescopic relationship between the guide rail extension and the guide rail may generally compensate for vertical structure compression that may occur over a period of time.
