If you're interested in the CPR, a good resource for locomotive painting info is Rail Canada, Volume 3. My copy is from the first edition in 1979, and covers from the early black scheme, through the various versions of the maroon and grey, and up to the multimark Action Red days. I don't know if this book has been reprinted with more up-to-date info, but it's good for the time frame mentioned. Included are diagrams, and b&w and colour photos, plus a roster.
