Under the supervision of a roundhouse hostler, Canadian Pacific Ten-Wheeler No. 472 was simmering away on one of the roundhouse lead tracks at Ottawa, Ontario when I snapped her in August 1955. She was a member of class D4g and shared specifications with No. 424. These small locomotives, a mainstay of CPR's branch line and local service to the end of steam, operated under the often-severe weather conditions of eastern Canada and northern New England. Jean-Louis Ouellette provided a photo of No. 472 snowbound on the CPR's line between Farnham and Bedford, Québec around 1938. No. 492 of this class is preserved at the Exporail, the Canadian Railway Museum in Saint-Constant (Delson), Québec, while No. 453 of this class is reportedly stored in Utica, New York with its future plans uncertain.
