Abstract
An articulated railroad flat car for transporting four short or three long semi-trailers comprises two units connected by a drawbar. A plurality of semi-trailer hitches are mounted on the units. The hitches are suitably spaced for securing either three long trailers or four standard trailers, using overhead loading or circus loading. When three long trailers are loaded, the middle trailer is attached to a hitch on one of the units and has its tandem resting on the other unit. The unit on which the tandem rests has a widened floor section at its end adjacent the drawbar to accommodate turning or skewing of the tandem when the car negotiates a curve.
