One of our box car/excursion cars has a couple of cracked 12" body center plates... A caboose truck is missing a 12" truck center plates. Is there a source beyond scrape piles?

Foundry or fabrication. You can control all the specifics to suit your situation.

Both items are commercially available and reasonably priced. No need to reinvent unless you have a true oddity...

As usual, your results may vary. Apparently not a real railroader...

The Unit Forgings has the right size center plate but not the right size flange, but may be an option... 12" center plates are found on 40 and 50 ton cars, which are now obsolete so not generally supported.

We are considering a pattern for our specific part, and new castings from that pattern. Wear on old parts may be an issue as well...

Too thick, too thin or wrong shape? Granted 12" is not the most common, but we've replaced several over the years in freight car land, and the bolster rings too.

We have always bought plate flame cut to the outside shape we wanted, then machined in the male or female profile to suit. Usual recipients have been our B&M coaches equipped with those horrendous spherical center plates invented by some enterprising side bearing salesman.

New flat female center plate. Males are made the same way.
