The Port Authority Trans-Huson (PATH) is a rapid transit railroad linking Manhattan, New York with New Jersey, and providing service to Jersey City, Hoboken, Harrison, and Newark. It is operated by the Port Authority of New York and New Jersey. PATH is one of the few rapid transit systems in the world that operate 24 hours a day, 7 days a week. While some PATH stations are adjacent to New York City Subway, Newark Light Rail and Hudson-Bergen Light Rail stations, there are no free transfers as the four systems operate independently.
