I, too, had no personal experience with them and don't have any Tonnage Ratings charts from that era, but based on photos, it would appear that on the San Joaquin and Western divisions, a single KM was rated the same (or close to) as two F7s or GP9s. Later, a single SD45 was rated for 10,000 tons on the "flatlands," and it was said that a single SD45 was considered the same as two F7s, so you can kinda go from there.
Ironically, the code I had to enter for this post was "YXVKM."
