AAR 70-Ton 3-Bay Open Hopper

Burlington Northern  BN 516330

Industry Standard Hopper.

An industry standard since the Thirties, the 3-bay hopper was adopted as an AAR recommended design.

Although offering greater carrying capacity than flat-sided cars, the joints were easily damaged by the sulfuric acid created by wet coal and the cars fell out of favor by the mid-1950s as repair costs mounted.
