Absolute newbie here (does this make my avatar read "Monon freeloader"?), but from my perspective (modeling Dearborn station trains circa 1956), I'd second passenger cars. I can't see Monon generating the kind of sales major manufacturers need to break even, but I wonder if a manufacturer of passenger car sides, like Union Station Products, M&R or Brass Car sides might not be talked into doing the Monon rebuilt hospital cars. Also strikes me as possible that as more passenger cars become available from Microtrains and Wheels of Time, some of these heavyweights might be close enough (haven't had the opportunity to study Monon heavyweights) for someone to consider doing a custom painted batch for Monon, as has been done with freight cars in the past.
