I used to have trouble associating these engines with Santa Fe, and didn't like them for that reason. Now, I can think of them as Santa Fe power, not just BNSF, and regret that they ran for such a short time for their original owner.
Outstanding work! :w20z6q: IIRC, Microscale has (or at least had) a sheet specific to the ATSF SD75M, although I can't find it on their website now. I know they had one for BNSF SD75I's when I bashed mine. Russ
