While some PATH stations are adjacent to subway stations in New York City and Newark as well as Hudson-Bergen Light Rail stations in Hudson County, there are no free transfers. The PATH system spans 13.8 miles (22.2 km) of route mileage, not including track overlap. Like the New York City Subway, PATH operates 24 hours a day. Opened in 1908 as the Hudson and Manhattan Railroad, a privately owned corporation, PATH since 1962 has been operated by the Port Authority of New York and New Jersey.
