ABSTRACT:
A rapid dump hopper car includes a pair of relatively lightweight doors which are opened and closed sequentially from an overlapping position by means of a longitudinally extending actuating mechanism movably supported on the underframe of the car. The doors include longitudinally spaced and transversely extending hinge bracket structures which are connected to the center sill and side sill of the car for relative hinging movements. The bracket structures also include overlapping portions and interengageable bars securely supporting the adjacent edges of the door in interlocking relation. Each hinged bracket structure also includes a ball and socket connection with actuating links which are connected to the longitudinal operating mechanism.
