Abstract: Each of first vehicles has an individual address dependent upon an insertion of a selective one of different keys into a socket in the vehicle. Each vehicle is movable in any desired direction on a first support structure formed by intercoupling male detents on first beams and female detents on other beams and on blocks. The first support structure may be, but does not have to be, intercoupled with a second support structure. The second structure may define a track on which an additional vehicle (e.g., a monorail) is movable in first and second opposite directions. Each of a plurality of manually operated pads generates signals for addressing any unaddressed vehicle and for providing movements of, and the performance of functions in, the vehicle when addressed. Each pad communicates the pad-generated signals to a connected central station. The central station communicates these signals by wireless to the vehicles.
