Overview: NJ TRANSIT’s Northeast Corridor Line is the busiest line in the NJ TRANSIT commuter rail system. Almost half of the commuter trains on the line during peak hours begin or end at an intermediate point just outside of North Brunswick, NJ, at the location of a large storage yard. As trains leave the yard and enter the NEC main line toward New York, however, they must cross three tracks at grade. Trains require long gaps in service to make this complex crossing which reduces capacity on the Corridor. This configuration can also create delays for NJ TRANSIT trains waiting to enter the NEC and for Amtrak trains that must provide space for NJ TRANSIT.
To address this problem, NJ TRANSIT and Amtrak hope to construct a grade-separated flyover that would carry NJ TRANSIT trains up and over the NEC main line, along with a new “loop” track that would connect the yard to the flyover and serve a new commuter station for North Brunswick. These investments would reduce delays for riders and support expansion of service to a new station.
