I have seen at least two specific photos of NYC Steam Locos in Gaylord. One was taken in the fifties and showed either a Hudson or Mohawk. I have been racking my brain and searching the web, so far all I am doing is going crazy trying to find it again! As soon as I do, I will post the link.
The second is a photo taken much earlier (ca 1910?). I should be able to post that if you are interested and I can drag it out of my computer's memory.
In the meantime, I can tell you that during the twilight of steam on the NYC, almost anything appeared on these Michigan Branch Lines. Hudsons and Mohawks were often seen, and of course, H10's and H5's. In the days of the earlier photo mentioned above, ten wheelers were common on the Mackinaw Branch.
