ABSTRACT:
A covered hopper railway car (10) for transporting difficult-to-unload ladings includes a pair of parallel, spaced apart side walls (12a, 12b) and opposed end walls (14a, 14b). A roof (16) covers the car and has an opening (18) therein for loading lading into the car. The bottom has outlets (24a-24g) attached thereto for discharging lading from the car. Each outlet comprises a drop-bottom outlet whose length and width are sufficient so as to substantially prevent lading from bridging over the outlet thereby facilitating discharge of the lading.
