North Jersey and South Jersey are separated by what river?
North Jersey North Jersey comprises the northern portions of the U.S. state of New Jersey between the upper Delaware River and the Atlantic Ocean. The designation of northern New Jersey with a distinct toponym is a colloquial one rather than an administrative one, reflecting not only geographical but also perceived cultural differences from the southern part of the state, with no official definition.
River Line (Conrail) The River Line is a rail corridor located between Jersey City, New Jersey and Selkirk, New York, running along the west side of the Hudson Palisades and after passing through a tunnel at Haverstraw, New York, along the west bank of the Hudson River. A parallel track, which was operated as part of the River Line from Jersey City to Weehawken, New Jersey, was known as the Weehawken Branch. The River Line has since been split into several sections, following the 1999 division of Conrail assets between Norfolk Southern Railway and CSX Transportation.
