Yesterday I mentioned the CB&Q SM19 series "Z" bracing.
They did specify Cor-Ten Steel. Basic design was used to
build cars from the late 30's until the early 60's.
From what I've heard it weathers much better and actually
works best when it's not painted.

Ok, Bill. To get back to freight cars, there are hundreds,
thousands, of examples
of proprietary freight car designs as well as modifications to
that ultimately did not pan out. So the PRR bought an
over-designed flat car? Is
this the first time someone overdesigned a freight car? Why did
the UP insist on
using Cor-Ten steel in its freight cars to save a few hundred
pounds of steel, at
the added complexity of extra side posts stiffeners and rivets
center rivets or ACR) when just about every other owner was
content using the
AAR standard design? And why did SP buy so many thousands of
cars years after most other railroads had accepted 10'6" as a
that matter, think of the vast numbers of 40' box cars built
after WWII that were
retired before their normal lifespans because they were
before 1970. The PRR's design department is not to blame for the
the PRR. That is all that I meant by that being a 'silly'
