Abstract
A flexible sheet is erected on four rigid poles to form three rectangular sides thus containing the empty space between intermodal freight containers on consecutive flat-bed rail cars thereby reducing the aerodynamic drag which results from the sizeable gap between containers which is not present between traditional box cars. The apparatus can be raised and lowered by a rope and pulley mechanism, and can be separated into halves to allow detachment of consecutive rail cars.
