My brother captured this broadside of Canadian National class S-1-b 2-8-2 No. 3275 resting near a water column at Stratford, Ontario on September 5, 1958. Members of the S-1 class typically had a grate area of 57 square feet, an evaporative heating surface of 3405 square feet, and 805 square feet of superheating surface. With these relatively modest dimensions, as twentieth-century main line freight power goes, the S-1s hauled the bulk of CNR heavy freight not handled by the system's more modern 4-8-4s.
