The Milwaukee Road engine is very cool looking. I live in Winnetka and have not seen it, but I think that line I am on was more a CNW line than a Milwaukee Road line. Growing up in Northbrook, I would see the Milwaukee Road engines all the time at the Shermer Road crossing as well as the Willow Road overpass (Willow and Shermer).
I have the MTH Metra engine, and would add the Milwaukee Road one.
