Canadian Pacific Railway 4-6-2 Locomotive No. 2317

History: Before the Canadian Pacific built the small 1200-series G-5 "Pacific"-type locomotives to replace earlier classes of ten-wheelers and light Pacifics, the railroad had acquired a much heavier class of 4-6-2 locomotives for main line passenger traffic. William H. Winterrowd had become chief mechanical officer of the Canadian Pacific Railway (CPR) in April 1918 as the World War was winding down. Under his supervision, and possibly that of his predecessor, wartime chief mechanical officer William E. Woodhouse, the drafting office had prepared designs for no less than four new postwar heavier and more powerful locomotives of the 2-8-2, 2-10-2 and 4-6-2 wheel arrangements (two classes of the latter). First to be constructed, ten new 2-8-2 Mikado types of Class P-2-a rolled out of CPR's erecting shops in April and July, 1919. Last to be produced, Winterrowd's 15 Class S-2-a 2-10-2 locomotives constituted at the time CPR's heaviest freight motive power, following the successful 2-10-0s Woodhouse had introduced. For passenger service, CPR needed heavier locomotives because "heavyweight" six-wheel truck all-steel cars had rapidly replaced the older, lighter wooden passenger cars on main line runs. Building on Vaughan's successful G-l and G-2 Pacifics manufactured well before the World War, Winterrowd's team produced plans for four G-3-a 4-6-2s with 75-inch drive wheels for service over relatively flat terrain and five G-4-a Pacifics with smaller 70-inch drivers for main line service in hilly terrain. Numbered 2300 through 2303, one of the G-3-a locomotives appeared in July 1919 and the other three in August. Construction of this type would resume with the G-3-b subclass in 1920 and extend with variations through G-3-j subclasses. Locomotive No. 2317, the eighteenth of the G-3 series, would be the seventh in the G-3-c subclass, which with its predecessors in that subclass was outshopped in June 1923. By that tine Charles H. Temple had succeeded Winterrowd as chief of motive power and rolling stock. Two more G-3-cs, Nos. 2318 and 2319, also came Out in June, followed by six more in July, before the railroad began procuring the next G-3 subclass, the G-3-d. These were the first locomotives in North America to have nickel steel boilers and the first Canadian Pacific engines to be built new with feedwater heaters. Whereas all the G-3-a and G-3-b subclasses had been built at CPR's own Angus Shops, the G-3-c and G-3-d locomotives were erected by the Montreal Locomotive Works. Ultimately, the CPR acquired 173 G-3 4-6-2 locomotives in nine subclasses. The G-4 class began coming out in October 1919, and totaled only 18 locomotives built in 1919, 1920 and 1921. The operational history of G-3-c locomotive No. 2317 awaits further research in Canada, but the locomotive is known to have been stationed in Winnipeg, Manitoba, for many years. Canadian Pacific apparently retired the locomotive from service and put her in stored status in 1959, after 36 years of operation.
