The Soo Line (the Minneapolis, St. Paul and Sault Ste. Marie Railroad) owned one McKeen Car, a 70′ Passenger/Baggage, 34 ton model.  It is not known how this railroad got this McKeen, whether from the factory or second hand from a railroad, but the car in this image looks unmodified, so it is possible that is was bought straight from the factory.
