I work at the UPS facility right next to the Rotem site, and have for the past several nights wandered up alongside the tracks on an old street that runs between UPS' parking lot and the tracks; the road ends at the Rotem factory. For starters, directionally speaking the tracks are to the west of the Rotem building; UPS (mostly its parking lot) and Oregon Ave are to the south-there is a crossing on oregon ave; Wolf St. to the north, also with a crossing; and Weccacoe Ave to the east, in the direction of the Delaware River. With that in mind, there are transfer tables to the north AND south of the building. The north side transfer table is clearly visible from wolf street, the south side one is visible by going up that road, however to get a clear view one may be considered trespassing as the siding at that location is fairly close to the street at that point; in fact, the street is mainly gravel by this point.
Three switches have been installed off the siding; the middle of the three, alongside the building, is for a lead that goes through the property fence, where it joins two tracks coming out of the building. The three become one right before the tracks ends at the transfer table. Another switch, on the northwest side of the bldg-visible from the Wolf St crossing-is currently a stub heading AWAY (?) from the building; it has been recently installed. Likewise, on the Oregon Ave (southwest), there is another stub that has been installed heading away from the building at a point just before the siding heads back into the main track to cross Oregon ave; the siding picks up again on the other side, currently holding empty well cars.
There are letters in white spray paint-like that used to mark out a work site for utility locating-that say "OCA", "OC1", "OC2", and "OC3", with the first three between Oregon Ave and where the siding comes out. I am supposing they may intend to connect the siding to the other across Oregon Ave. There is a similar mark on the Wolf St-end as well, but there isn't a whole lot of room on the other side of the crossing for a third track.
