The Pennsylvania Northeastern Railroad (reporting mark PN) is a short-line railroad operating on trackage mostly in Bucks and Montgomery counties to the north of Philadelphia, Pennsylvania.

The Pennsylvania Northeastern Railroad operates on 55.53 miles (89.37 km) of SEPTA-owned trackage mostly in Bucks and Montgomery counties to the north of Philadelphia, with some lines extending into northern portions of Philadelphia.

The Pennsylvania Northeastern Railroad offers various freight rail services including transloading of bulk commodities between railcars and trucks, rail access to warehouse facilities including Lansdale Warehouse and AmeriCold Logistics LLC in Hatfield and storage of railcars.

[3] In December 2010, it was announced that a newly formed shortline, the Pennsylvania Northeastern Railroad, would be taking over freight operations in the Lansdale area from CSX.

Under the new arrangement, CSX would still move freight north from Philadelphia while the PN would serve customers in Lansdale, Hatfield, Souderton, Telford and Warminster.
