Abstract
Air flow guide members at each end of the cargo carrying structure of an open top gondola type railway car, together with rounded transition or corner surfaces on the exterior of the car and aerodynamically shaped and oriented cross braces within the car serve to reduce aerodynamic drag on the car as it is moved. Additionally, to further enhance the energy efficiency of the car, the cargo carrying structure is formed predominantly of a light weight weldable metal, such as an aluminum alloy, and the side support members are placed on the interior wall of each side to provide a smooth, minimized air flow resistant side surface.
