Disclosed is a series of stacked intermodal containers, being pulled by a locomotive of a train, with aerodynamic drag reducing devices. A first set of containers has an aerodynamic drag reducing device with a drag reducing fairing and an attachment frame attached thereto. The attachment frame includes first and second mounting devices configured to be removably mounted to connection openings of the corner fittings of the top container of the first set of containers. The first mounting device(s) may be rotatably locked within the top connection openings, while the second mounting device(s) may be hooks for latching into the bottom connection openings. A method of attaching the aerodynamic drag reducing device is also disclosed.

What is claimed is: 1. A method for reducing aerodynamic drag of a series of stacked intermodal containers, the series having at least a first 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, end walls, and side walls connected by a frame to form a box with corners at each junction of three of the walls, and each container having corner fittings at each corner associated with at least a first of the end walls thereof, the corner fittings comprising a plurality of connection openings each configured to receive a part of a mounting device, the method comprising: 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 to the top container of the first set of containers at the first end wall having the corner fittings associated therewith using a first mounting device and a second mounting device, each mounting device extending from the attachment frame and into at least one of the connection openings of the corner fittings associated with the at least first of the end walls of the top container of the first set of containers. 2. A method according to claim 1, wherein the first set of containers is a leading set of containers in the series and the first end wall of the top container of the first, leading set is a front wall facing a forward direction, and wherein the first and second mounting devices connect to the corner fittings at the front wall of the top container of the first, leading set such that the aerodynamic drag reducing device faces the forward direction for forward movement. 3. A method according to claim 2, wherein the first mounting device further comprises a rotatable locking device, and wherein the method further comprises releasably securing the attachment frame to the corner fittings by rotating the rotatable locking device. 4. A method according to claim 3, further comprising rotating the rotatable locking device from an unlocked position to a locked position via a toggle arm. 5. A method according to claim 2, further comprising latching hooks of the second mounting device into at least one connection opening of the corner fittings. 6. A method according to claim 5, further comprising pivoting a leverage handle of the second mounting device from a first position to a second position so as to securely fasten the hooks in the connection openings of the corner fittings. 7. A method according to claim 1, further comprising removably mounting the first mounting device to the connection openings located in top corners of the top container and removably mounting the second mounting device to the connection openings located in bottom corners of the top container. 8. A method according to claim 7, wherein the connection openings in the top corners are adjacent the first of the end walls of the top container and wherein the connection openings in the bottom corners are adjacent the side wall of the top container. 9. A method according to claim 8, further comprising securing the attachment frame to the corner fittings by rotating a rotatable locking device. 10. A method according to claim 1, further comprising providing a second, aerodynamic drag reducing device comprising a second drag reducing fairing and a second attachment frame, and removably mounting the second attachment frame using third and fourth mounting devices which extend from the second attachment frame and into at least one of the connection openings of corner fittings in each corner of a top container of a second set of containers. 11. A method according to claim 1, further comprising: positioning the aerodynamic drag reducing device in relation to the top container; aligning the attachment frame with the corner fittings of the top container; inserting at least the first mounting device into at least one connection opening of a first corner fitting, and securing at least the first mounting device in the at least one connection opening. 12. A method according to claim 11, further comprising: inserting the second mounting device into a second connection opening of a second corner fitting, and securing the second mounting device in the second connection opening. 13. A method according to claim 1, wherein the series of stacked intermodal containers are attached to a locomotive in a train. 14. A method according to claim 1, wherein the first set of containers is a trailing set of containers in the series and the first end wall of the top container of the first, trailing set is a back wall facing a rearward direction, and wherein the first and second mounting devices connect to the corner fittings at the back wall of the top container of the first, trailing set such that the aerodynamic drag reducing device faces the rearward direction that is opposite a direction for forward movement.
