The New York, Susquehanna and Western Railway (reporting mark NYSW) (a.k.a. the Susie-Q or the Susquehanna) is a Class II American freight railway operating over 500 miles (800 km) of track in the northeastern states of New York, Pennsylvania and New Jersey. It was formed in 1881 from the merger of several smaller railroads. Passenger service between Northern New Jersey and New York was offered until 1966. The railroad was purchased by the Delaware Otsego Corporation in 1980, and became a regional player during the 1980s in the intermodal freight transport business.
