The USRA cars had a 3 panel end (not the two panel found on the Accurail 7/8 end), with 5/5/5 corrugation patterns.    (Have not looked up if there were USRA cars with other ends.)

There were some "clones" of the USRA design that had two panel ends with a 7/8 rib arrangement, built in the early twenties. Canadian Pacific had some, as did C&NW, but these later cars were slightly reduced in height compared to the original.

The Accurail "nine panel" single sheathed car with corrugated steel ends specifically models a group of early CN automobile cars that had the same IH as the boxcars, AFTER the were rebuilt with single six foot wide doors.
