Abstract: The present invention provides a dual rail track system for independently moveable carts in an industrial control environment in which upper and lower rails of a track are substantially “L” shaped to allow upper and lower groups of rollers of a cart to orthogonally contact the upper and lower rails, respectively, to provide vertical and horizontal control of the cart while in motion along the track. The shape of the rails and arrangement of the rollers, orthogonal with respect to the rails in vertical and horizontal planes, provides an efficient support system allowing high speed. movement of carts, including through turns, with only two rails and with symmetric weight distribution of the cart. Flexible members provided with respect to each roller also provide resiliency to allow the rollers to adapt to variations in the track.
