Slateford Junction was a railway junction in the small town of Slateford, Pennsylvania. It was built in 1911 to connect the existing mainline of the Lackawanna Railroad, the so-called Old Road, with the new Lackawanna Cut-Off. It was in service until 1979. The junction sat 28.5 miles (46 km) west of Port Morris Junction, where the Cut-Off connects with what is today New Jersey Transit's Morristown Line. When operations began on December 24, 1911, the junction merged four tracks (two main tracks and two sidings) from the Cut-Off with two from the Old Road. An interlocking tower at the junction opened four days before the Cut-Off itself. The junction also included a 60-foot turntable, but this saw limited use; it was dismantled in the 1930s and its pit filled in shortly thereafter. The tower closed on January 11, 1951; the switches at the junction became hand-thrown with electric locks.Today, the Pennsylvania Northeast Regional Railroad Authority (PNRRA) owns the surviving tracks at Slateford Junction as well as the right-of-way of the Cut-Off on the Pennsylvania side of the Delaware River. The Delaware Lackawanna Railroad currently operates freight trains at Slateford Junction and over the rest of the PNRRA's tracks. As of 2022, there are plans to restore service along the Cut-Off via NJ Transit and Amtrak.

The Paulins Kill (also known as Paulinskill River) is a 41.6-mile (66.9 km) tributary of the Delaware River in northwestern New Jersey in the United States. With a long-term median flow rate of 76 cubic feet of water per second (2.15 m³/s), it is New Jersey's third-largest contributor to the Delaware River, behind the Musconetcong River and Maurice River. The river drains an area of 176.85 square miles (458.0 km2) across portions of Sussex and Warren counties and 11 municipalities. It flows north from its source near Newton, and then turns southwest. The river sits in the Ridge and Valley geophysical province. The Paulins Kill was a conduit for the emigration of Palatine Germans who settled in northwestern New Jersey and northeastern Pennsylvania during the colonial period and the American Revolution. Remnants of their chiefly agricultural settlements are still found in local architecture, cemeteries, farms and mills, and the area remains largely rural. Flowing through rural sections of Sussex and Warren counties, it is regarded as an excellent place for fly fishing. The surrounding area is used for hiking and other forms of recreation such as observing birds and other wildlife.
