My Kalmbach "Diesel Locomotive Rosters" book from 1982 shows the Soo still had FP-7 500A, 502A, and 2500A on the roster, along with F7A 2201A. 2500A was eventually donated to "The Depot" in Duluth MN. They restored it to it's original maroon-and-gold 'pine tree' paint scheme, and use it on fantrips and dinner train trips on the North Shore Scenic RR: https://duluthtrains.com/
BTW the Soo's F units never had m.u. cables in the nose, only on the rear, so you would often see a multi-unit lash-up with F units on either end, both facing "out", with B units, GPs, Alcos, etc. stuck in between.

mbinsewi I'm a member of the SOO Line Historical & Technical Society FB group. I asked the group, we'll see what I get for answers. I'm guessing into 70's. Mike. EDIT: The general consensus from the group, is into the late 70's. They started dropping off the roster in 77 - 79 with the arrival of the new GP38's. Also, 4 units remained in snow plow service until Jan. 85.

How long did the SOO line use their F7s in freight service?
