In 1944, Montreal Locomotive Works built 20 bullet-nosed, green-skirted 4-8-2s for the Canadian National. They were the last steam engines ordered for the railroad, and their lighter Mountain-type design was intended to render them usable over more of the system than the U-2 4-8-4s, the last of which were delivered the same year. The bullet-nosed U-1-f Mountains featured a one-piece cast frame incorporating the pilot and cylinders, and "streamlined" internal steam flow that allowed them to outperform the CNR's earlier 4-8-2s. They had 24x30-inch cylinders and 73-inch disc drivers, a relatively high 260-pound boiler pressure, a 70 square feet of grate area. Weighing 416,500 pounds, they developed 52,315 pounds of tractive effort. They had 3584 square feet of evaporative heating surface and 1570 square feet of superheating surface, and were at home in either passenger or freight service.
