Built by ACF from 1940-1953, the 70-Ton Hart Ballast Cars were formally known as Hart Selective Service Ballast Cars, due to the use of specially-designed doors which allowed the lading to be discharged one of three ways: to the center of the rails, to the center and sides of the rails, or to the side of the rails only.
