In 1949 sugar was shipped in boxcars in bags, barrels or bulk. The first airslide hopper was patented in 1953, again after the date of the Red Owl data. Attached is a photo of bulk sugar begin unloaded from a boxcar.
Great photo! Two questions come to mind - how was the sugar loaded? Were roof hatch box cars seen in this service?
Thanks!
