Context: 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 Hightstown Industrial Track is a rail line in New Jersey, owned and operated by Conrail Shared Assets Operations (CSAO).  The line runs from Jamesburg, New Jersey to the current end of track at Cranbury, New Jersey.  The line was built by the famous Camden and Amboy Railroad, one of the first railroads in the country.  It has been operated by the Camden and Amboy, the Pennsylvania Railroad, Penn Central, and finally, Conrail. The Lincoln Secondary is a railroad line owned and operated by Conrail in the U.S. state of Michigan as part of its Conrail Shared Assets Operations. The Winchester and Western Railroad (reporting mark WW) is a shortline railroad operating from Gore through Winchester, Virginia and West Virginia to Hagerstown, Maryland.  It also operates several lines in southern New Jersey, connecting to Conrail Shared Assets Operations at Millville and Vineland. The Conrail Lehigh Line is a railroad line in New Jersey that is part of Conrail Shared Assets Operations under the North Jersey Shared Assets Area division.  The line runs from CP Port Reading Junction in Manville to Oak Island Yard in Newark.  The line is double-track and signaled through its entire length.  The line began operations in 1999 using former existing tracks from Manville to Newark that was once part of the original Lehigh Line which is still in existence and is owned and operated by Norfolk Southern Railway. The Southern Secondary is a rail line in New Jersey, operated by Conrail Shared Assets Operations (CSAO) and owned by New Jersey Transit.  The active portion of the line runs from South Amboy to the current end of track at Lakewood, NJ.  The line is owned by New Jersey Transit, but the southern portion (Red Bank, NJ to Lakewood, NJ), is not shared with passenger trains.  Beyond Lakewood, the tracks are owned by CSAO as far as Lakehurst, but are inactive between Lakewood and Lakehurst. Roselle Park is a New Jersey Transit railroad station in Roselle Park, New Jersey.  Located on the Conrail Lehigh Line which is owned by Conrail Shared Assets Operations on West Lincoln Avenue between Chestnut Street and Locust Street, it is served by Raritan Valley Line trains that travel between Newark Penn Station and Raritan.  There is also limited service to High Bridge and New York Penn Station and one weekday morning train to Hoboken Terminal. The Robbinsville Industrial Track is a short freight line that runs between Bordentown, New Jersey to the Yardville section of Hamilton Township, New Jersey.  The line is part of Conrail Shared Assets Operations (CSAO) and was originally part of the Camden and Amboy Railroad and later served as part of the Pennsylvania Railroad, Penn Central Transportation and then Conrail. The Norfolk Southern Railway (reporting mark NS) is a Class I railroad in the United States.  With headquarters in Norfolk, Virginia, the company operates 36,200 route miles in 22 eastern states, the District of Columbia, and has rights in Canada from Buffalo to Toronto and over the Albany to Montreal route.  NS is responsible for maintaining 29,000 miles, with the remainder being operated under trackage rights from other parties responsible for maintenance.  The common commodity hauled on the railroad is coal from mines in Indiana, Kentucky, Pennsylvania, Tennessee, Virginia, and West Virginia.  The railroad also offers the largest intermodal network in eastern North America. Conrail Shared Assets Operations is the commonly used name for modern-day Conrail (reporting mark CRCX).  Conrail is an American railroad company.  It operates three networks—the North Jersey, South Jersey/Philadelphia, and Detroit Shared Assets Areas, where it serves as a contract local carrier and switching company for its owners, CSX Transportation and the Norfolk Southern Railway.  When most of the former Conrail's track was split between these two railroads, the three shared assets areas (a total of about 1,200 miles of track) were kept separate to avoid giving one railroad an advantage in those areas.  The company operates using its own employees and infrastructure, but owns no equipment outside of MOW equipment.
