Abstract
Apparatus for enclosing open end portions of railway hopper cars in order to reduce the aerodynamic drag. Each corner area of each end is provided with a shroud which includes a side plate and an end plate. The side plate covers the open side area at the end of the car and also covers the first vertical rib on the car side. The end plate covers the part of the end of the car adjacent the corner. Each shroud is shaped in an aerodynamically efficient configuration to minimize air resistance.
