Rivet Counter HO Scale GATC 4180 Airslide Covered Hopper, GACX/Champion Spark Plug

In 1963, GATC introduced the 4180 Cubic Foot Airslide Covered Hopper. Designed for shippers of such commodities as flour, starch, and sugar, these two-bay cars featured ten round loading hatches and four outlets. These unique cars also 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.
