In 1928 the Canadian Pacific took delivery of twenty class T1a 2-10-4s from Montreal Locomotive Works that had the same boilers as those of the K1a 4-8-4s. Although most railroads that had 2-10-4s called them the Texas type, the CPR named them Selkirks for the range of the Canadian Rockies across which they operated. These oil-burners, rolling on 63-inch driving wheels, sustained 275 p.s.i. of boiler pressure and had cylinder dimensions of 25½x32 inches. They weighed 440,200 pounds and developed 78,000 pounds of tractive effort. Their large grate area totaled 94 square feet, and they boasted 4931 square feet of evaporative heating surface plus 2112 square feet of superheater surface. If not as sleek as the later semi-streamlined Selkirks, the beefy T1a class operated in the same service that included hauling the CPR's transcontinental passenger trains through mountainous terrain. Tac Foley contributed this photo by A. B. Crompton of No. 5918, looking freshly shopped, at an unknown location on the CPR's coast-to-coast system. The slant-sided cab was a distinctive feature of all the Selkirks, required because of tunnel clearance in their operating territory. The exception was No. 5911, which received a different cab after incurring damage in a wreck.
