the rail line serving the port is called the glass house running track and is an extension of the salem branch. on the verge of abandonment by conrail, the southern section of the route from swedesboro to salem was purchased by the county in 1983 and is leased to southern railroad of new jersey (srnj). long neglected, it is in poor condition and travel speeds are very slow. the line is undergoing upgrades to the rail bed, trackage, a trestle at oldman's creek, and other work. at swedesboro, srnj interchanges with conrail shared assets operations to reach pavonia yard, the regional rail center.
