In one aspect, a system includes a wheeled vehicle and a track structure. The wheeled vehicle has a drive unit including an opposed pair of inwardly biased drive wheels with substantially vertical axes of rotation and a traction system operable to dynamically adjust the degree of inward bias. The track structure includes a center rail member including an l-beam having two substantially horizontal flange portions and a substantially vertical web portion therebetween having two wheel contact surfaces on respective opposite sides thereof grippable by the opposed pair of inwardly biased drive wheels. Rail support structure depends from the center rail member. An elevated pair of rails is attached to the rail support structure. Each rail is supported by the rail support structure so as to provide an upper, lower, and lateral surface suitable for rolling engagement by a weight-bearing wheel, undermount wheel, and guide wheel, respectively, of the wheeled vehicle.
