GATE ASSEMBLY UNIT FOR HOPPER-TYPE RAILROAD CAR ABSTRACT A hopper-type railroad car for transporting ballast used for roadbed restoration includes a set of bottom outlets for discharge of the ballast. Gate assembly units are installed over these outlets to provide regulation of the ballast dis- charge. Each unit has an inner and outer opening selectively covered by an arcuate shaped door. Each door is connected by linkage to an inner and outer door shaft carried concentrically by the unit. Selectively rotation of either shaft moves the respective door to cover or uncover the unit openings to regulate ballast discharge.
