Here are most of the places that I've railfanned between Utica & Syracuse. There are a number of West Shore, NYC, Lehigh Valley, & O& W remains between the two cities if you're interested. The Mohawk, Adirondack & Northern operates on part of the old NYC mainline, and R.W. & O mainline in downtown Rome usually between 11 am and 1 pm during weekdays. Also some switching at Griffis Park.
