I was in Harrison about 2 years ago and as I recall there was no sign that any train had crossed (traveled west of) Frank Rodgers Blvd. on the Center St Branch in a long time. THere used to be some kind of refinery or chemical plant in Harrison next to the Passaic River, but that is long gone, maybe 5 years, and probably condos by now. No mo re industry on that side of Frank ROdgers Blvd for sure, and probably also on the east side too.
I have read that the Center St track in Harrison east of Frank Rodgers Blvd is (was?) used to exchange cars between CSX and delivery to the Morristown and Erie RR (via delivery on the NJ Transit Morristown Line). But I don't know if that is happening any more now that the M&E lost the contract for providing freight service on the old NJT Lackawanna lines a few years (?) ago.
Regarding the Harrison Industrial, it might be the stub that left of the Lackawanna branch from Harrison to Kingsland, and a few sidings near where it branches off the Lackawanna main line to Newark and Morristown. Google maps shows at least one chemical type plant with a lot of tank cars by Sanford Ave https://goo.gl/maps/taY22efCMJPYMPU76
, but I don't know how old the photo is.
