The CN Fulton Sub became part of New York Central and Conrail through leases, mergers, and takeovers, and was assigned to CSX Transportation in the 1999 breakup of Conrail. Under the purchase of CSX's St. Lawrence Subdivision by the Canadian National Railway in August 2019, the Fulton Line was sold off as well with the line. Current ownership by CSX expires on May 21, 2020, with CN assuming duties thereafter.
