ABSTRACT:
A lightweight hopper-type rail car provides for a smooth exterior surface so as to minimize aerodynamic drag thereon when the car is in motion. The railcar includes a cross ridge arrangement which greatly increases the fabrication efficiency of the car as well as providing a smooth interior surface so as to allow the maximum release of bulk material contained within the car.
