Model Railroading > Unexplained tank on Beer Cars

I was under the impression that a beer cars was simply a 60' insulated boxcar. But when I was painting the hubs of the wheels, I noticed the large tank in the underframe. I'm pretty sure the cars didn't have a hidden reefer unit, so it may have been some kind of cryo refrigeration system. Anyone know what the tank was for?

Auxiliary air reservoir for the cars' internal air bladder lading restraint system.

Ok another can of worms I hope not, does anyone have a pix of that? Never heard of such but sounds like a good way to prevent damage to goods.

Weyehauser and others use one used/still use reinforced paper bladder
bags to secure and restrain cargos.

I think I remember these tanks being under my HO Hamms Beer cars 41
years ago-sigh.

They were on just about all of the "beer cars" built by Pacific Car and Foundry.
