Patent ID: 7784409

Claim:
A method for reducing aerodynamic drag of a series of stacked intermodal containers, the series having at least a first, leading set of containers, the set of containers comprising a top container stacked above a bottom container; each of the containers comprising a top wall, a bottom wall, front wall, back wall, and side walls connected by a frame, the bottom wall having a tunnel extending from a first end of the container toward a second end of the container, the method comprising: positioning the top container of the first, leading set of containers on the bottom container such that the tunnel of the top container faces a forward direction in line for forward movement; providing an aerodynamic drag reducing device comprising a drag reducing fairing and an attachment frame, the fairing being attached to the attachment frame, and removably mounting the attachment frame using at least one mounting device extending rearwardly from the attachment frame in the tunnel of the top container of the first, leading set of containers such that the aerodynamic drag reducing device faces the forward direction.
