That's great Jim.

I was thinking of rummaging around in the 27' boxcar photos.  But I think we can be entirely happy with Michael's 4' wheelbase design.

A question to Michael about wheelsets:   I suggested the Kaydee wheelsets for HOn3 based on comparisons with various other trucks I have.  The Kaydee wheels have the narrowest  (most nearly scale correct) tires of any. That'll reduce any need to make the truck width between journals wider to accommodate them.  Their flange OD is .342" or 29.8 scale inches.  I don't have the NMRA standards handy, but that's as small as any of the 26" wheels I have.  That's certainly an issue with HOn3, the flanges are too big.  Please let me know if there are clearance issues with your UP design.  I'd probably prefer a small indent in the transoms for flange clearance if needed (like the old Grandt 3'7" trucks), rather than increasing the wheelbase.  

many thanks,
John
