These 50 ft rib side box cars with single door and no roofwalk are blue with  yellow lettering and run on Barber Roller Bearing trucks.  Built by FMC in the late 1970s for Railbox, it was later transferred to C&O, then Seaboard, and finally arrived on the CSX roster in the 1980s. Shopped in the 2010s, the car received a fresh coat of CSX blue.
