But I wonder if that is really accurate? For example, would the similar cars used on other railways that used Z bracing (rather than the pressed steel shapes on the USRA and CP cars) be considered better or poorer - or was the difference inconsequential from the point of view of boxcar design evolution?I don't know the answer to your question, Rob, but SP and several other railroads which had received USRA single-sheathed cars did not duplicate them in subsequent years but went back to Z bars. At the least, they were unimpressed with the hat-section bracing.
