Ontario Northland Northerns

The Ontario Northland Railway is owned by the Province of Ontario, Canada and its main line goes from North Bay to Hudson Bay. In 1936, this busy railway was feeling the pressure for more motive power and ordered four 4-8-4s (road numbers 1101 through 1104) from the Canadian Locomotive Works.

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.
