N ACF 2970 Covered Hopper, EL with ACI Primed For Grime #21378/21380/21385 (3) Overview
The 2-bay covered hopper first entered service in the 1950s. The cars handle loads such as cement, sand and similar denser bulk commodities. In the 1960s, American Car and Foundry introduced the Centerflow design. The car's rounded body provided structural strength without the added weight of bracing, as well as making gravity unloading easier. This 2-bay car came in a 2,970-cubic foot capacity.
