The American Car & Foundry built this 3 bay ACF Center Flow covered hopper with elongated hatches in June 1973. It is painted in ATSF brown with white lettering. The trucks and couplers are also brown. Number ATSF 313838 is part of a 1,000-car fleet of class LO hoppers with a 4,600 cu ft, 200,000 lb capacity equipped with Barber Roller Bearing trucks. Unlike most railroads, the ATSF remained virtually intact from its beginnings in 1859 up to its merger with Burlington Northern in December 1996.
