The first tracks in Pennington were completed in 1873, providing service to the Mercer and Somerset rail line but by 1876, the Delaware and Brook Bound line ran it out of business. The Reading Railroad built this station in 1882, three years after it gained lease over the Delaware & Bound Brook Railroad. Roughly 50 trains per day stopped at the station by the 1900's, carrying mail, passengers and freight from Trenton, Philadelphia and New York. The station was staffed around the clock by an agent and three clerks. After World War I, automobile ownership rose and the station declined, cutting Sunday services in 1945. By 1962, Reading Railroad had only two trains stopping at the station and in 1967 discontinued service completely. Today, the line is part of CSX's Trenton Subdivision, though plans by New Jersey Transit to revive for commuter rail service are often discussed. These plans, however, do not include the reopening of the station, which is now a private residence.
