S2 Class 2-10-2 Santa Fe Type

There were only 15 of these powerful 2-10-2's built by the CPR. Initially used for heavy freight service in the mountains they were soon reassigned because their slow speed of only 30 mph hindered the flow of traffic. Most (9, oil-fired) were then used for helper service on the steepest parts of the mainline in the Rockies while 3 (5812-14 Duplex stoker equipped) worked helper service out of Moose Jaw. 5812 was converted to oil and given the tender (4100 oil 11,500 water) off scrapped high-pressure 2-10-4 8000 and transferred to BC. 5814 was lost in a wreck at Dennis, Alberta with 2829 on Number 8 a fast passenger train and scrapped 4/40. The first three (5800-02 hand-fired) were used in transfer service in Montreal where their slow speed would be no problem and their high tractive effort very useful.
