A 1943 RGS lists T-12's at 67 tons rating on the 4% grades. 205 tons on 1.8%, 210 tons on 1.7%. (RGS had a long strech of 1.25%, Delores to Montelores but the line on into to Rico was 1.8% and the 1943 table just gives Delores-Rico ratings)
I can't find a later D&RG(W) tt with T-12 in it right now.
NOTE: At some point in the 1920's, D&RG(W) reduced the rating on all its older engines. For ex: Class 125 was rated at 200 tons Chama-cumbres in July of 1919, Class K-27 at 183 tons in 1943. Class 60 at 95 tons, Class C-16 79 tons(same dates).
I'm not sure when this took place, looking at 3rd div tt's it was before 1927 and after 1920.
Moral: Ratings from older timetables need not apply.

ps 1943 RGS tt lists "Class of engine, T-12. No. of engines, 166-177." Just a bit out of date!
