The Presque Isle Subdivision is owned by the State of Maine, but operated by the Maine Northern Railway. The subdivision is 25.3 miles in length beginning at Squa Pan and ending at Presque Isle.
I don’t have a current timetable for this subdivision, and couldn’t find anything recent. As such, these miles are based off of a bit of math from an old B&A timetable, and the FRA maps.
