At the Steam Era Frieght Car site there is a photo of a NP boxcar -- here:
http://www.steamfreightcars.com/gallery/boxauto/np39731main.html that I have
a couple of questions about.

First, not being very sharp on trucks, I see this one does not look to have
integral journal boxes which made me think Andrews but there's something
about the angle of that lower brace that suggest nope... something else. So
if anybody recognizes these on sight, what kind of trucks are they?

Second question what's the deal with that huge steel center sill? I was
under the impression steel center sills were not usually this size.
