I use Kadee #831 couplers on front and rear of my USAT F3 A & B units using the standard USAT mounting. My minimum curves are 10’ diameter.
Hope this helps; Rob
I have used combination of off-set Kadees and Aristocraft, but currently using highly modified USAT on the front's and Kadee's on the backs and both ends of the B units, makes it alot easyer to seperate them.
