On February 1, 1867, the C&A and NJRR were informally joined as the United New Jersey Railroad and Canal Companies (UNJ). The Pennsylvania Railroad (PRR) approved a lease of the UNJ on May 15, 1871, and the UNJ approved May 19. On May 18, 1872, the C&A, D&R Canal and NJRR were consolidated, forming the United New Jersey Railroad and Canal Company. The new company was split into two divisions: the New York Division consisted of the NJRR and the C&A Trenton Branch towards Philadelphia, while the Amboy Division was the original C&A main line.
