Description
Railroad Short Name: UP
In 1963, GATC introduced the 4180 Cubic Foot Airslide covered hopper to their catalog. Designed for shippers of such commodities as flour, starch, and sugar, these two-bay cars featured ten round loading hatches, and four outlets. As with their other Airslide designs, it featured their patented “Airslide” unloading system, which used pressurized air to aerate the special fabric lining of the bays, effectively fluidizing the commodity and allowing it to flow more easily during unload
Union Pacific purchased two groups of 4,566 cubic foot Airslide hoppers, UP classes CH-100-48 and CH-100-49 in 1981 and 1982 respectively. They were delivered in “aluminum” (silver) paint including the trucks and featured red billboard lettering.
