Southern spoken here!
I have a problem that I would like your comments on.I currently am modeling in N scale.Thanks to my LHS having great sales and inventory of road names I like.I now have quite a collection of HO engines and rolling stock.(Around 20 new engines and 30 pieces of rolling stock.) I now have the urge to set up an HO layout also.Don't have enough space in the building to put both on the floor side by side.I know many people have multi level layouts,but has anyone used two different scales? Which would you put on the upper level,N or HO? Any comments good or bad are welcomed.
