It's Staley's, the corn syrup plant. We have two fo these in town, both served by rail.
Not much security there. In fact, by state law, I'm not trespassing, because the fence is not locked (wide open) and it's not posted. I would rather not be discovered, because if they choose to verbally tell me not to enter their property, I would from that time forward be trespassing if I did enter. They fenced it off about two years ago and diligently kept it locked up for about two weeks.
The yard lead, south of the crossing that I've shot a lot of the pics from, is fenced on both sides with a gate on the end. No business reason to ever open that gate, but it's never even locked. I guess they take a diesel down there and get a pizza for the crew from the Pizza King (PK!) just outside the gate.
All these fences and a bunch of landscaping went up in an effort to make the railroads "disappear" from Lafayette as part of the major "Railroad Relocation" project. Another part of relocation project was to move hte main line to the new "Corridor" along the river, so as not to inconveniance the natives.
