Modeling X29 patch panels

Mark Heiden

Hello everyone,

I have two questions about modeling the patch panels that were added
to Pennsylvania X29 boxcars. There are two photos of X29s with these
panels at:

First, how were these panels attached to the cars? One photo shows
rivets, while the other seems to be welded. Were both methods used
concurrently, or did one succeed the other?

Second, are the panels one long piece of steel, or are they made up of
individual pieces? Were the patch panels typically all the same
