Abstract: A method of transporting containers on a rail car is described. The method includes the steps of, first, providing a frame having at least two longitudinal beams and at least two cross beams. The at least two cross beams extend substantially perpendicular to, and interconnect, the at least two longitudinal beams. The two longitudinal beams may be cambered along the length of the beams. Next, the method includes the step of attaching a first container to a first end of the frame. Then, the first container and the frame are loaded into the rail car. Finally, the method includes the step of loading a second container into the rail car and onto a second end of the frame.
