Pumpers, the tracks you speak of are the old Metuchen receiving yard which ran between Lincoln Tower and Edison Interlocking. Back in the 90's, they were used as overflow tracks for inbound and outbound traffic from the yard at Whitman Avenue. I believe the receiving yard had 5 tracks back then. Also the Amazon and Fed Ex warehouses next to the receiving yard occupy the site of the Mobil Chemical plant. The cars for Mobil were stored at the west end of the receiving yard.
