As far as I know, Cor-Ten steel was the reason that UP (and later SP)
used Alternate Center Rivet style side sheathing on cars built in their
home shops. ACR is the signature of cars that used the thinner steel.


Thanks for the correction -
Next Question - did any other car builder than Pullman-Standard use
Cor-Ten Steel?
