The present invention generally relates to support frames and rail cars comprising first and second side drive plates, first and second cross members connecting the respective ends of the side drive plates, third and fourth cross members connecting the side drive plates at a select distance from the first and second cross members, a coupling assembly situated at the first cross member and adapted to connect another rail car thereto, and first and second diagonal support members connected to the first cross member at an angle sufficient to substantially direct forces from the coupling assembly to the third cross member and side drive plates. The support frames and rail cars may be used for conveying bulk materials on a rail transport system. |
