An operable wall system having a primary track and several storage tracks intersecting said primary track can be improved by the use of rotary switches at the intersections of the primary and storage tracks and by the use of a positioning structure carrying holders capable of being actuated so as to engage and disengage wall sections or panels being moved between said primary and said storage tracks. When such an operative wall structure is employed to move a wall section or panel on to the primary track from the storage tracks the panel to be moved is engaged by the holders and then these holders are moved through the movement of the positioning structure so as to place the section or panel being moved on to the switches. The holders are then disengaged from the panel or section and the switches are manipulated so as to allow the panel to be moved along the primary track. In storing panels the reverse of this series of operations is employed.
