In 1972 Canadian National Railway restored 6060 to operating conditions and used her to haul steam fan excursions out of Toronto, Ontario. After more than five years of retirement, she was restored a second time with the help of the Province of Alberta and most notably, with the help of volunteers from the Rocky Mountain Rail Society. 6060 was a participant in Steam Expo in Vancouver, British Columbia in the year 1986.
