Hey Lee!
The Jackson and Sharp passenger cars are correct for...
West Virginia Midland! All you have to do is letter them.
You could letter an entire passenger set WVM and be near correct. Betcha it would sell too!
The loco would be #10 and W V M on the tender in RR Roman (white)
The cars would have West Virginia Midland spelled out in RR Roman. (White)
Accucraft/AMS has On30 Jackson & Sharp coaches already.
