ABSTRACT:
A golf cart system includes a longitudinal rail having a transverse cross section defined by spaced side walls joined at lower ends thereof by a bottom wall having an inner upper surface. The side walls have at upper ends thereof upper walls extending inwardly toward each other and having inner lower surfaces. The upper walls have spaced inner edges having extending upwardly therefrom mouth portions. The inner edges and the mouth portions define therebetween a longitudinal groove opening downwardly into the interior of the rail. The rail is embedded in the ground of a golf course with upper edges of the mouth portions substantially flush with the ground surface. A golf cart is movable along the rail and has support structure extending downwardly therefrom through the longitudinal groove of the rail. Wheels are mounted on the support structure within the rail interior and contact the inner upper surface of the rail bottom wall. The cart supports a drive to rotate the wheels to move the cart along the rail. The cart is prevented from falling sideways from the rail by rollers supported by the cart and positioned within the rail interior and contacting the inner lower surfaces of the rail upper walls.
