Two members of Canadian National's U-1-f class 4-8-2s, Nos. 6066 and 6069, pose at Toronto's Spadina Street terminal in May 1952. This photo, from the collection of Tom Rock of T.D.R. Productions, is the work of an unidentified photographer. Today No. 6069 is on display in Sarnia, Ontario. In their later years eleven members of this class were assigned to service in western Canada and had their bullet-nose stream-styling removed (including No. 6066, and 6062 previous); some or all were also converted to burn oil. The device alongside the fourth driver is an exhaust steam injector, which these locomotives used in lieu of a feedwater heater.
