Valley Railroad coal-hauling operations in Pennsylvania and the Port of New York and New Jersey to serve consumer markets in the New York metropolitan area, eliminating the Phillipsburg connection with the CNJ that had previously been the only outlet to the New York tidewater; until it was built, the terminus of the LVRR had been at Phillipsburg on the Delaware River opposite Easton, Pennsylvania. The Easton and Amboy was used as a connection to the New York metropolitan area, with a terminus in Jersey City, New Jersey. Construction commenced in 1872 as soon the Easton and Amboy was formed; coal docks at Perth Amboy were soon constructed, and most of the line from Easton to Perth Amboy was graded and rails laid. However, the route required a tunnel through/under Musconetcong Mountain near Pattenburg, New Jersey (about twelve miles east of Phillipsburg), and that proved troublesome, delaying the opening of the line until May 1875, when a coal train first passed over the line. To support the expected increase in traffic, the wooden bridge over the Delaware River at Easton was also replaced by a double-tracked, iron bridge. At Perth Amboy, a tidewater terminal was built on the Arthur Kill comprising a large coal dock used to transport coal into New York City. These tracks were laid and the Easton and Amboy Railroad was opened for business on June 28, 1875, with hauling coal. The Easton and Amboy's operations were labeled the "New Jersey Division" of the Lehigh Valley Railroad. The Easton and Amboy had already completed large docks and facilities for shipping coal at Perth Amboy upon an extensive tract of land fronting the Arthur Kill. Approximately 350,000 tons of anthracite moved to Perth Amboy during that year for transshipment by water. Operations continued until the LVRR's bankruptcy in 1976. The marshalling yard is now the residential area known as Harbortown. Passenger traffic on the LVRR's Easton and Amboy connected with the Pennsylvania Railroad (PRR) at Metuchen, New Jersey, and continued to the PRR'S Exchange Place terminus in Jersey City (that connection was discontinued in 1891 after the LVRR established its own route to Jersey City from South Plainfield). Eventually, the Easton and Amboy Railroad was absorbed into the parent Lehigh Valley Railroad. In 1875, the LVRR financed the addition of a third rail to the Erie Railroad main line so that cars could roll directly from colliery to the
