I was not taking pictures yet when my family went on a summer vacation through Ontario and Quebec in August 1972. We stopped at CP's Sherbrooke yard and found a lot of activity, with two RS10s and one RS18 all working the yard at the same time. Here I'm admiring RS-10s 8824, no doubt thinking that 8824 had a unique number among CP's RS-10s because it was a wreck replacements for FA-1 4016. R. T. Steinbrenner Photo
