Abstract
A multiple track railroad system for use with two adjacent sets of parallel continuous tracks with the tracks having a distance therebetween and each set of tracks including two continuous rails having a distance therebetween. The railroad system includes an engine for pulling a train that has a set of wheels riding on at least two of the rails, and the engine has a width equal to at least one set of the tracks. The railroad system also includes at least one rail car connected to and propelled by the engine, wherein the rail car spans and extends beyond the outer rails of both sets of tracks. The railroad system further includes at least four car-trucks supporting the rail car, with two of the car-trucks on each of the sets of tracks, and each car-truck includes at least four wheels, with two wheels each riding on opposing rails of a set of the tracks; and trundle carrier assemblies, one each mounted to a bolster on each of the car-trucks with the upper end of the carrier assemblies being attached to the rail car to permit the car-trucks to move vertically or horizontally transverse on the tracks relative to the rail car to accommodate variations in the elevation or distance between the tracks.
