Bordentown Secondary

The Bordentown Secondary was originally a freight railroad line in New Jersey, running from Pavonia Yard in Camden to Trenton. Today, a large portion of the line from Bordentown to Camden is used for New Jersey Transit's River Line light rail service. Conrail Shared Assets Operations continues to operate freight trains on the line, but these operations are restricted to overnight hours.

The line that meets with the Bordentown Secondary in Bordentown, the Robbinsville Industrial Track is operated by Conrail Shared Assets Operations and extends from Bordentown to nearby Yardville, New Jersey which is located within Hamilton Township.

The trackage that makes up much of the present-day Bordentown Secondary was originally laid by the Camden and Amboy Railroad in the 19th century. The line completed the connection between New York City and Philadelphia, via ferries between Pier 1 in New York, and South Amboy, New Jersey, and between Camden and Philadelphia. The Camden and Amboy was eventually purchased by the Pennsylvania Railroad (PRR), then became a Penn Central Transportation line after the PRR-New York Central Railroad merger in 1968, and was transferred to Conrail in 1976.
