A passenger conveyor system is arranged along a path in a racetrack fashion. Drive members associated with lateral edges of each pallet step surface move with the pallets through straight sections of the path to avoid relative movement between the pallets and adjacent structure. During turnaround sections, where the pallets are beneath a floor surface, the drive members move relative to each other, with one set of drive members becoming temporarily disconnected from each other, to permit the pallets to make a transition and a turnaround. In the illustrated example, a drive mechanism cooperates with at least one set of the drive members to transmit a motive force to propel the pallets along the path.
