As much as I'd love to build some moguls right about now, you're probably right.
From what I can tell the CP had only the six Danforth moguls (the larger Nevada, Utah and Humboldt, and the smaller Hercules, Oneonta and Washoe). The roster doesn't list what happened to the Nevada, but Utah, Hercules and Oneonta became 4-4-0s and Washoe and Humboldt were both gone by 1889...leaving CP with at most a single mogul until the turn of the century. It's probably a better idea to focus my time and energy into some good, bad, and extremely
ugly 4-4-0 and 4-6-0 variations for 1868-1905 or so.
