These locomotives were designed by the railway's own motive power department and were some of the lightest ever built, weighing only 371,320 pounds. They were styled with smoke deflectors and running board skirting and made a fine appearance on the head end of a passenger train.
The design included 69" drivers, 22.5 x 30 cylinders, a 275 psi boiler pressure and a tractive effort of 54,500 pounds.
There are no survivors.
See "Temiskaming & Northern Ontario (Ontario Northland) 1100-1103" in Canadian Rail No 487 (March-April 2002), pp. 80-82 (including a reprint of an August 1936 report for Canadian Railway and Marine World.). Thanks to Chris Hohl for supplying a PDF of this CR issue on Canadian 4-8-4s. Works numbers were 1919-1920 in June 1937, 1921 in July, 1922 in August.
Like the TP&W H-10s, these Northerns are little known and far lighter than the average for the wheel arrangement. They were nonetheless big and powerful locomotives fitted, said the CRMW account, with the "last word in modern equipment." The long list included SKF roller bearings in all truck boxes, a Standard BK stoker, Nicholson thermic syphons, Dominion foundries and Steel nickel steel locomotive frames. The firebox heating surface area includes 91 sq ft (8.45 sq m) of arch tubes and thermic syphons.
The CR account noted that "the T and NOR ...was among the earliest users of the Franklin Supply Company locomotive booster in Canada ...[T]hat it regards the device favorably is evidenced by the fact that it has utilized them in its latest power." The booster increased starting tractive effort by 10,450 lb (4,740 kg or 46.5 kN).
They moved passenger trains along the T & NO's mainline from North Bay to Hudson Bay. In 1946, the T&NO was renamed Ontario Northland, although the numbering on these very northerly Northerns remained the same. All were taken out of service in 1956 when the ON was fully equipped with diesel.
