US 7,841,280 B2 · Drag reducing devices for stacked intermodal rail cars

Abstract

Disclosed is a series of stacked intermodal containers, being pulled by a locomotive of a train, with aerodynamic drag reducing devices. The series includes at least a first, leading set of containers and a second, trailing set of containers. The first, leading set of containers has an aerodynamic drag reducing device with a drag reducing fairing and an attachment frame attached thereto facing a forward direction. The attachment frame includes at least one mounting device configured to be removably mounted in the tunnel of the top container of the first, leading set of containers. Additionally, the second, trailing set of containers may include a second, aerodynamic drag reducing device, also attached via a gooseneck tunnel. Curtains may also be attached between a plurality of intermediate or adjacent sets of stacked containers to assist in reducing drag on the train when moving.

Dependent claims

A system 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 top container positioned on the bottom container such that the tunnel of the top container faces a forward direction in line for forward movement;
the system comprising:
an aerodynamic drag reducing device comprising a drag reducing fairing and an attachment frame, the fairing being attached to the attachment frame;
the attachment frame comprising at least one mounting device extending rearwardly therefrom, and
wherein the at least one mounting device of the attachment frame is configured to be removably mounted in the tunnel of the top container of the first, leading set of containers in a forward direction such that the aerodynamic drag reducing device faces the forward direction.
