Info needed on HO Atlas Kaiser Aluminum hopper
Author: SimpleMoMike

I am looking for more prototype information on this HO scale Atlas ACF 6 bay cylindrical hopper painted for Kaiser Aluminum. So far all I have found is ACF built these from 1961-64, 288 were aluminum body and 917 were steel body with 3960 cuft capacity. Were the Kaiser ones aluminum or steel? Any one have a prototype dimensions?

Thanks in advance for any additional information.

The light weight of only 46,000 pounds screams aluminum to me.  Great info Mr. MRL.

No kidding, steel hoppers like this are closer to 35 tons, not 23 tons. Aluminum is a good bet, but something you would expect of a Aluminum Company.
