A fair amount of that loop track still exists at Fox Lake so it should show up on Google Earth. We explored it when Soo Line 2-8-2 1003 hauled a photograopher special freight past the junction. Fox Lake is a neat little town when lots of good ideas for modeling.
The Fox Lake track plan was the subject of an excellent Model Railroader article by, naturally, Gordon Odegard. February 1976 – get the issue if you can, or buy a copy of the article from Kalmbach. The thrust of the article was how to use the Fox Lake track plan as part of a layout. Highly recommended.
