From signal bridges and crossovers at Hunter (MP 10.5), where the NJT line departs to the southwest (a connection to the former Lehigh Valley), there is a through truss bridge carrying a line west, dual road bridges overhead, a passenger station with two island platforms and two through tracks in the center for Newark Airport, and a single track line trailing in from the east side, passing under the easternmost line (which rises up to accommodate this), carries the former Lehigh Valley freight line from Oak Island Yard. with a connector on the north side dropping down under the bridge along the west side of the NEC, the four (actually five, for a stretch) track line heads south-southwest, with speed of 110-25 on the inner tracks, and 90-25 on the outer tracks, past a road bridge overhead, signal bridges and crossovers at Lane (MP 12.3), where the freight line from Oak Island Yard trails in from the east side, connecting to the middle track, with the easternmost track passing over it on an embankment and a bridge, and (as a direct corollary) the fifth track ends.
There is a bridge over a street at the north end of the passenger station with two side platforms (high-level, of course) at North Elizabeth (MP 13.0), with a road bridge overhead within the platforms, two bridges over streets, a signal bridge, a bridge over a street, the passenger station with two side platforms at Elizabeth (MP 14.1), where the line jogs south, and a bridge over a former Jersey Central line, before resuming south-southeast, a bridge over a street, a street to the east, a signal bridge for the crossovers, a bridge over a street, crossovers at Elmora (MP 14.7), where extra tracks start on each side, the highest passenger speeds rise to 125 mph, and freight speeds rise to 35 mph, with a bridge over a street in between the crossovers, and a signal bridge to the south, a bridge over a street, a road bridge overhead, a signal bridge at South Elizabeth, a through truss bridge carrying the former Staten Island Railway line, a signal bridge, a street alongside to the west, a bridge over a street, the passenger station with two side platforms at Linden (MP 17.3), where the eight to ten track Stiles Street Yard is on the east side, a bridge over a street, a signal bridge at North Rahway (MP 18.8), where there is a bridge over a river, two bridges over streets, extra track on the west side, a bridge over a street, the passenger station with two island platforms at Rahway (MP 19.5), and crossovers at Union (MP 19.7), where the double track North Jersey Coast Line turns away south-southeast with two separate duck-under tracks (both descending below main line level) and a wye on the east side of the main line, and those extra tracks end.
