Then they were mated with the last three H24-66 "Train Masters" in the fleet as three GP9-TM sets. When those finally retired in 1975 or so, CP was running humps with GP-F7B-GP sets (GP was usually a GP7 or GP9) which lead into the era of Geep rebuilding. Two F7B's were "slugged" and kept going in hump service into the late 90's. CP chopped those 3 GP9′s (8633-35) in 1970-71 for hump service, running them with pairs of SW1200RS units (GP-SW-SW sets).
