From the picture it looks like only a sort of runaround past the yard ladder is used as the loading track --- all the rest of the track looks out of service. The "runaround" track leads back to the endloader and the coal pile, which is where I assume all the action happens. So I don't see why you'd have those two tracks with hoppers and the loco on them as anything but abandoned. In essence the prototype has only one working spur and an entire yard w/ ladder as unused, decaying track, right?
