This 100-Ton 3-bay open hopper with rib sides is brown with white lettering and run on Barber Roller Bearing trucks. Built by Frisco from a Bethlehem Steel kit in 1978, this car was transferred to Burlington Northern shortly after. After the merger it was renumbered into series 615521-615998. In total, BNSF inherited nearly 9,000 open hoppers during the mid-1990s.
