Overview: At Hunter Interlocking, the NJ TRANSIT Raritan Valley Line joins the NEC just west of Newark Penn Station. Currently, peak-hour Raritan Valley Line trains headed east to Newark must cross three to four NEC main line tracks at grade to access the eastbound tracks at Newark Penn Station. With forty Newark-bound trains per day, Raritan Valley Line trains create conflicts on one of the busiest stretches of the entire NEC. During the morning rush, Raritan Valley Line trains are often delayed as they wait for a “slot” to make the complex crossing, while Amtrak trains must occasionally wait for the trains to complete the crossing. To solve these issues, Amtrak and NJ TRANSIT intend to partner to construct the Hunter Flyover, which would carry Newark-bound Raritan Valley Line trains up and over the six-track NEC main line. This new flyover would remove many directional conflicts between trains and dramatically reduce delays for NJ TRANSIT and Amtrak.
