The recent ExactRail Evans boxcar in HO scale would be a match for these two cars with some slight modification to the side sill.
Chris-are you sure on that? from what I can see of the model pics they show these as Plate C
cars, while the USRE cars are all Plate B cars from what I've found. It'd take some cutting to make
them the correct height. As far as I know, the only Plate B models that could be a Railbox is the old
Athearn BB model, which has the incorrect roof & too wide for starters, & the Intermountain PS
undec with the Superior door (that a good chunk of got patched for BN)
I could be wrong, & will listen to otherwise (you've corrected me before on some things Chris ;D) as
I've wanted to do one of these cars for several years, as well as the Golden Tye kit RBOX (2000
something series)
