Pressurized air is used as the unloading mechanism, the product is blown out via pipe connections.
It's a dry (powder) products hopper car.

Are the hoppers pressurized during transport, or only as an aid in unloading? I could see pressurizing a car with dry nitrogen for a short trip to preserve the contents and keep it from absorbing water.

Doughless In many ways, these covered hoppers are the modern-day successor to the older Airslide Covered Hoppers. I'm curious as to the contents transported in these. They are for dry, powdered commodities, and I know that flour and powdered sugar are popular contents. I'm more curious about the non-food industry uses of these hoppers. What dry powdered products could be carried in these that are not edible food related? And I'm speaking mainly of the larger covered hoppers. Cement ingredients such as fly ash or lime dust are carried in the shorty two bay types, but other products could be carried as well. Ideas?

Hi Douglas,
One thing I did when researching these cars was to download the Atlas page http://archive.atlasrr.com/HOFreight/arc-hopressureaide.htm and Google all the Liveries - which gave me the Chemical Companies and the types of Products they are transporting.
Also, there is some off-loading info at:

I have another download from a site that seems no longer to work, but I can't find it right now.
I hope this helps, Paul

cv_acr Anything dry and finely powdered (and not so heavy to overload the weight capacity of the car). Powdered clays & minerals. Various dry chemicals. Oil well drilling "mud". Back on the food side, corn starch would probably be one.

Yes. I think some of the minerals would have to use the two bays because of weight.
It comes down to what chemicals are used in powdered form?
I just read where the 3D printing process prefers powdered plastic over plastic pellets.
Mybe the guys over at Trains forum have more info.
