The PATH rail system connects Manhattan in New York City with New Jersey.
PATH stands for Port Authority Trans-Hudson. It serves Manhattan terminals at World Trade Center and 33rd Street, while its New Jersey stations include Newark, Harrison, Jersey City and Hoboken. Trains cross beneath the Hudson River through tunnels, making PATH a crucial interstate link for commuters and visitors.
The system began operation in 1908 as the Hudson & Manhattan Railroad. Its tunnels were among the earliest successful rail tunnels under the Hudson, overcoming difficult underwater construction conditions. In 1962, the Port Authority of New York and New Jersey acquired the financially troubled railroad and renamed the system PATH.
Although PATH functions much like a subway, it is legally classified as a commuter railroad under Federal Railroad Administration jurisdiction. That status reflects its history, its shared infrastructure near Newark and its connection to the broader rail network. Pennsylvania is a tempting wrong answer because the region has major Pennsylvania Railroad associations, but PATH’s current routes serve New Jersey and New York, not Pennsylvania.
