A majority of 8-panel hoppers were the result of the rebuilding of other styles of 2-bay hoppers. Offset side hoppers were particularly good candidates for this conversion. The argument for the offset side car is that by placing the side sheets on the outside of the ribs, you could then fill the volume between the ribs with coal (or other commodity.) The downside was that the offset side cars were more difficult to build and repair. Also, the load often packed in the corners between the rib and side sheets, trapping moisture and making repairs more frequent. Rebuilding them with 8 full length panels and 9 posts was relative easy and cheap, more than making up for the loss in cubic capacity. The rebuilt car could provide another 15 to 25 years of revenue service. These ready-to-run cars feature die cast slope sheet-hopper bay-center sill assembly; injection molded plastic sides, ends, and hopper doors; fully molded brake tank, valve and air lines; body mounted brake hose detail; load; body mounted magnetically operating knuckle couplers; close coupling; and metal wheels. MSRP: $27.95 each.
