NYSW meaning in Regional ?

The New York, Susquehanna and Western Railway (reporting mark NYSW) (or New York, Susquehanna and Western Railroad and also known as the Susie-Q or the Susquehanna) is a Class II American freight railway operating over 400 miles (645 km) of track in the northeastern U.S. states of New York, Pennsylvania, and New Jersey.

The railroad was formed in 1881 from the merger of several smaller railroads. Passenger service in Northern New Jersey was offered until 1966. The railroad was purchased by the Delaware Otsego Corporation in 1980, and saw success during the 1980s and 1990s in the intermodal freight transport business.

The railroad uses three main routes: a Southern Division running from Jersey City, New Jersey to Binghamton, New York and a Northern Division formed by two branches north of Binghamton serving Utica and Syracuse. The Utica Branch is notable for street running down the center of Schuyler Street.
