There is a large lumber yard with sidings in Newark sandwiched between Frelinghuysen Ave and the NEC line just north of the Lehigh line connection. What business owns that yard? None of the street fronting businesses around it seem to have any signs indicating they are in that business.
It seems to be called Poinier Street Limited:
116 Poinier St, Newark, NJ 07114 ; (973) 242-7994
Information seems sparse, but I did only a superficial search.
They did get a mention in the Hillside/Irvington Branch thread on this forum
