Hi k4driver:
Sure - re-skin away.

P.S. Uploaded six different 3-bogey boxcars earlier this morning. Yes I said 3, its not a typo. The extra one is in the center of some 60 ft boxcars circa 1850 or so. The center bogey does track the center line of the rails like the real one which slid back and forth. They didn't like sharp curves so didn't last very long but a few did exist. In Trainz they will negotiate a very sharp curve without derailing (and look quite silly doing so, lol).
