Though the passenger facilities are located within Hoboken, large parts of the infrastructure that supports them are located in Jersey City. The Hoboken/Jersey City line cuts across the rail yard at a northwest diagonal from the river to the intersection of Grove Street and Newark Street. It is at this corner that Observer Highway begins running parallel to the tracks and creating a de facto border for Hoboken. The Long Slip (created with the landfilling of Harsimus Cove) creates the southern perimeter of the station, separating it from Jersey City's Newport neighborhood.
