The ROCK 3.0: Soo Line Visitor

I have become more fascinated with the Soo Line after visiting Dubuque, IA and watching an old Pentrex video on the railroads of the Upper Mississippi.  No, I'm not switching eras or locale.  Calm down!  I purchased a Soo Line GP35 that will work on my layout from time to time.  The Soo Line probably didn't show up very often down on the Illinois Division, but it's my world and I'll do as I please.
