Wisconsin Great Northern's F unit shoves back with a few cars and will tie onto a much larger string a little farther east (and visible in the distance). The road's SW1 has been switched onto the siding at Spring Brook. Once the F has hold of all the cars on the mainline it will bring them down to the west switch so that the WGN's newest two locomotives can be spotted on the siding with the SW1. Delivered today and purchased from Canadian National are ex-Wisconsin Central (nee-Algoma Central) SD40-2 #6006 and ex-Duluth Missabe & Iron Range SD38 #200.
