The Central New York Railroad (reporting mark CNYK) is a shortline railroad operating local freight service along ex-Southern Tier Line trackage (ex-Erie Railroad/Erie Lackawanna Railway mainline trackage) in the U.S. states of New York and Pennsylvania. The line begins at Port Jervis, following the Delaware River to Deposit and the Susquehanna River from Lanesboro, where it passes over the Starrucca Viaduct, to Binghamton. It is a subsidiary of the Delaware Otsego Corporation, which also owns the New York, Susquehanna and Western Railway, operator of through trains over the line (along with the Norfolk Southern Railway, lessor).
