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.
