Overview
The Port Reading Railroad was a railway company in the United States that developed a freight route across central and northern New Jersey. Incorporated in 1890, it completed its principal line in 1892. The company was controlled throughout its corporate existence by the Reading system, whose earlier corporate form included the Philadelphia and Reading Railway and whose later form was commonly known as the Reading Company. The railroad was created to connect the Reading system's Trenton-area route with a purpose-built port facility at Port Reading on the Arthur Kill in Woodbridge Township, near Perth Amboy. Its western end began at Port Reading Junction in Manville, New Jersey, where it connected with the Lehigh Valley Railroad and the Central Railroad of New Jersey. From there, the line ran eastward across Middlesex County to the waterfront. The route provided the Reading system with access toward the New York and New Jersey port area and supported through freight movements between points south and west of New York Harbor and the port terminal. Port Reading was not simply a local passenger destination. The terminal and railroad were developed principally to handle the commercial and shipping requirements of the Philadelphia and Reading Railway. A related connection along the Raritan River linked the Reading system's Trenton line with the Port Reading route, allowing freight from the Reading network to reach the Arthur Kill waterfront. The terminal's position gave the Reading system an alternative means of accessing New York-area maritime commerce without relying exclusively on routes farther west or on other rail carriers. Like many American railroads, the Port Reading Railroad faced declining traffic, deteriorating infrastructure, and increasing financial pressure during the twentieth century. Secondary and branch lines were particularly vulnerable because their parent systems tended to prioritize routes with heavier traffic and stronger strategic value. By the time Conrail assumed control of much of the northeastern United States rail network in 1976, the former Port Reading route had been renamed the Port Reading Secondary and had become a lightly used line serving local industries. That role continued through the 1980s and much of the 1990s. Conrail generally routed larger movements toward the New York area over the Lehigh Line, leaving the Port Reading Secondary with a comparatively limited function. Conditions changed after the late twentieth-century revival of interest in freight rail, driven in part by growing freight demand and congestion on regional highways. When CSX and Norfolk Southern divided Conrail in 1999, the two companies retained the Port Reading Secondary and several other strategically important terminal-area routes within Conrail Shared Assets Operations. This jointly owned operating structure was designed to provide neutral switching and access in the New York metropolitan region. Conrail Shared Assets Operations subsequently upgraded portions of the Port Reading Secondary to support heavier and longer freight movements. The route became an additional access path to rail facilities in the Port of New York and New Jersey, including connections toward the Chemical Coast Line and intermodal facilities. Although the original Port Reading Railroad no longer operates as an independent company, its route survives as the Port Reading Secondary and remains part of the freight infrastructure serving industrial and port markets in New Jersey.
History
The Port Reading Railroad emerged from the Reading system's effort to establish a direct freight connection between its lines in central New Jersey and a new shipping terminal on the Arthur Kill. The company was incorporated in 1890 and completed its main line in 1892. Its western terminus was Port Reading Junction in Manville, near Bound Brook, where the railroad connected with the Lehigh Valley Railroad and the Central Railroad of New Jersey. The line proceeded eastward across northern Middlesex County to Port Reading, a purpose-built port facility in Woodbridge Township near Perth Amboy. The railroad was closely tied to the Philadelphia and Reading Railway and remained under Reading control throughout its corporate life. Its purpose was primarily commercial and logistical rather than passenger-oriented. Through the Port Reading route and the affiliated waterfront terminal, freight from the Reading system's Trenton line could move toward the New York-area ports and points beyond. A connection constructed along the Raritan River linked the Trenton route with the Port Reading line, creating a through route between Reading-controlled territory south and west of New York and the Arthur Kill waterfront. Physical remnants of portions of this connection have survived in the area. During the twentieth century, the Port Reading Railroad experienced the same broad deterioration that affected many American railroads. Competition from highways and changing industrial patterns reduced rail traffic, while the Reading system faced mounting financial difficulties. Branches and secondary routes such as Port Reading received less maintenance and investment than the system's principal corridors. As the Reading system's condition worsened, the line's role narrowed to local industrial service. Conrail's creation in 1976 brought the former Port Reading Railroad route into the consolidated northeastern rail network. Conrail referred to it as the Port Reading Secondary. At that point it was described as a lightly used line, with service largely limited to local industries. During the 1980s and early 1990s, Conrail generally favored the Lehigh Line for much of its traffic moving into the New York region, reducing the strategic importance of the Port Reading Secondary. The route gained renewed relevance in the late 1990s as freight volumes increased and congestion on northeastern highways made rail capacity more valuable. In 1999, CSX and Norfolk Southern divided Conrail, but the companies did not assign the Port Reading Secondary exclusively to either successor. Because the line was close to the New York metropolitan market and formed part of a complex terminal-area network, it became part of Conrail Shared Assets Operations, a jointly owned organization responsible for switching and operating selected Conrail properties in the New York, Philadelphia, and Detroit areas. Under the shared-assets arrangement, the Port Reading Secondary received infrastructure improvements intended to accommodate longer-distance freight and intermodal movements. The line provided an additional route toward facilities in the Port of New York and New Jersey, including connections with the Chemical Coast Line and intermodal terminals operated or supported by the Port Authority of New York and New Jersey. The former company's corporate identity disappeared, but the route continued to serve the regional freight system under the Port Reading Secondary name. Its history therefore spans three distinct phases: a Reading-system port connection, a lightly used Conrail secondary line, and a strategically useful shared-access route within the modern New Jersey freight network.
- 1999Placed within Conrail Shared Assets Operations
Following the CSX–Norfolk Southern division of Conrail, the Port Reading Secondary was retained within their jointly owned Conrail Shared Assets Operations structure.
- 1976Route conveyed to Conrail
The Port Reading Railroad's line became part of Conrail's northeastern United States network and was identified as the Port Reading Secondary.
- 1892Main line completed
The railroad completed its principal line from Port Reading Junction in Manville to the Port Reading terminal on the Arthur Kill in Woodbridge Township.
- 1890Company incorporated
The Port Reading Railroad was incorporated in the United States to develop a Reading-controlled route between central New Jersey rail connections and the Port Reading waterfront terminal.
- Infrastructure upgraded for additional freight capacity
Conrail Shared Assets Operations invested in improvements that allowed the Port Reading Secondary to handle increased freight and intermodal traffic serving the New York and New Jersey port region.
Products and positioning
A Reading-system freight connector designed to link central New Jersey rail routes with a waterfront terminal on the Arthur Kill and, in its later operating form, to provide additional freight access to the Port of New York and New Jersey.
Port Reading main lineRail freight route1892
The railroad's principal route ran from Port Reading Junction in Manville eastward across Middlesex County to Port Reading on the Arthur Kill. It was built to connect Reading-system territory with a purpose-built waterfront shipping terminal and supported freight movements between the Reading network and the New York-area port market.
Port Reading waterfront terminal connectionPort rail access1892
The Port Reading route served a terminal constructed by the Philadelphia and Reading Railway on the Arthur Kill in Woodbridge Township. The connection gave Reading-controlled freight a path toward maritime transfer and New York-area port traffic, making the railroad an important component of the system's broader through-routing strategy.
Port Reading SecondaryRail freight route1976
After the line entered Conrail in 1976, it was designated the Port Reading Secondary. The route initially carried relatively limited local industrial traffic, but later improvements made it an additional path for freight and intermodal movements toward facilities in the Port of New York and New Jersey.
