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 predominately 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.

A railway car having a cargo carrying structure having a bottom closure structure and a pair of side walls and forward and rearward end walls engaged with and extending upwardly from said bottom closure structure for forming an open top space for containing cargo and means for guiding air flow being engaged with an upper portion of said forward end wall for guiding air flow through said space for reducing aerodynamic drag on said car, and said means for guiding air flow including forwardly extending means extending forwardly of the forward end wall for guiding air flow upward over the forward end wall when the railway car is moved in a forwardly direction and rearwardly extending means extending rearwardly of the forward wall for guiding air flow downward into the cargo space rearward of the forward end wall when the railway car is moved in a forwardly direction whereby turbulence and resulting aerodynamic drag created by the forward wall are reduced, and said rearwardly extending means for guiding airflow downward into the cargo space being adapted to guide air flow upward over the forward end wall when the railway car is moved in a rearward direction for reducing aerodynamic drag resisting movement in the rearward direction.
