The fall colours are ablaze in colour at Heyden, Ont., as CN P633, better known as the Agawa Canyon Tour Train, races into the setting sun behind a trio of F40PH-2s and a sold-out 16 car train. Knocking down the final 14 miles of its 228-mile roundtrip from Sault Ste. Marie to Canyon, P633 is on the home stretch of its run across one of Canada's most iconic and beloved stretches of railroad.
