Montreal Locomotive Works delivered thirty class H1c Hudson type locomotives to the Canadian Pacific Railway in 1937. Unlike the CPR's earlier 4-6-4s, these engines were semi-streamlined with a recessed headlight, side skirting and a largely unbroken boiler contour. Their red, black and silver livery contributed to their distinctive look. The "Royal Hudson" crown (see the comments for No. 2850) is clearly visible on No. 2822, which surprised me by arriving unannounced with a train from the west while I was exploring the CPR engine terminal at Ottawa in August 1955. For other information about these semi-streamlined Hudsons, see the notes for Nos. 2836 and 2852.
