Yes, this is the NYS&W's "Central New York" leased railway owned by Norfolk Southern. I know, its a mouthful and may be confusing.
Line was originally the Erie mainline from Binghamton east to Port Jervis and eventually to NYC. Ended up with Conrail then NS. They leased it to a subsidiary of NYS&W for tax reasons. NYS&W maintains the line, has obtain tax incentives and has gotten grants to upgrade the track and signal system.
NYS&W runs trains on the line mostly at night between Binghamton and NJ. Trains run east Sunday, Tuesday and Thursday nights around 6-8pm. The returning trains leave NJ at 4-6pm on Mon, Wed, and Fri. There are locals once in a while too and they run as needed.
