I have found only few Lionel trains at garage sales but in 2005 I hit a mother load of Plasticville for $2. It included an Airport Building, Hanger, Union Station, Hall, Cathedral, 2 story house, Filling Station, Turnpike building, Frosty Drive in stand, and a un-built black Signal Bridge. I had several Plactiville kits before and now have way too many to fit on my medium size layout but I change them out once in awhile.
Many are on my new train board shown below with a Plastiville town main street, farm and airport.
I have used two coaling tower Plasticville kits to make a modified coaling station tower and a coal mine.

We love Plastiville around here for my 50's period O27 layout.
To see how I made the layout check the OGR link belowhttps://ogrforum.com/...ra-027-layout?page=1
Post 1 on page one has a Table of Contents to find out where to see how I built a $10 Turntable, Round House, Actionable Touch Track Diagram Control Panels and many homemade cars.
