Until I saw these, I thought of toy trains as something set up in a basement.
Having them outdoors added to the realism.
I found them in the Overland Park Arboretum and Botanical Gardens in Kansas.
Trains were models of those that ran from 1890 to 1950.
Even the bridges were replicas: Kaw River Bridge, Harry S. Truman Bridge, and Fairfax Bridge.
