Hmmm...good question...Even though MN&E owned the branch to North Port, I think the yard area you are referring to was the GR&I (later Pennsy) yard. I have an old Traverse City map somewhere, but I don't recall as to the MN&E used GRI trackage to get to the North Port branch, or they actually had their own track thru that area. Guess I have to locate that map.
