To be precise they were mostly n the 4th division lines when first delivered, then mostly moved to 3rd Div. ca. 1932-33. From then until late 1950 K-36's were usually on 4th, K-37's on 3rd but there were lots of exceptions. For example, in the current 1936-37 series of posts Jimmy has been doing 481 & 485 have been working out of Salida and 494 was on 4th div from October until January. If you check his past posts, you'll find the same general kind of thing then too.

ps Yes, I know D&RGW started shuffling the divisions around in the mid-20's and that by 1930 all the narrow gauge was in the Alamosa Division, I just find the 3rd/4th arrangement useful for organizing things.
