If NYSW is actively marketing the Utica branch, it has yet to publish tariffs on its web site for points south of Sangerfield/Waterville along the line (eg, there are no tariffs shown for Norwich or Shelburne). The tariffs for the so-called "Utica Group" include only the following stations, which are all serviced from Utica via CSX interchange:
Chadwicks, NY
Clayville, NY
New Hartford, NY
New York Mills, NY
Sangerfield, NY
Paris, NY
Richfield Junction, NY
Utica, NY
Waterville, NY
And at the south end of the Utica branch, the "Binghamton Station Group" references only Binghamton, Chenango Bridge, and Chenango Forks.
Furthermore, in the Lumber and Related Panel Products Tariff document, effective 1/1/2018 through 12/31/2018, is this text:
Utica Station Group: - Interline traffic to/from stations contained in the Utica Station Group must be routed via interchange with the CSX at Utica, NY.
The other published commodities tariffs currently in effect (Grains and related products, plastics, and Fertilizer) indicate the same stipulation re: Utica Station group.

Perhaps the NYSW web site is not yet up to date wrt new tariffs to market the whole of the Utica line....
