The Northern Liberties & Penn Township Railroad Company was incorporated in Pennsylvania on April 23, 1829, to build a railroad from Front Street at the Delaware River through what was then the independent District of Northern Liberties and Penn Township (now both part of the City of Philadelphia) to connect with the state-owned Philadelphia and Columbia Railroad near Broad and Vine Streets. This volume is the basic surviving record of the company's monetary transactions during its period of construction and independent operations.
