Looking at both Google Earth and Google Maps, you can find the site just east of the Bill Futch Road grade crossing, which is a short distance north of where the road connects to Arden Loop Circle. Google Earth shows what appears to be a long-abandoned plant, largely obscured by trees, where some of the structures have been demolished in recent years; however, there seems to be some new activity on the western side of the old plant grounds, and this locomotive may be associated with it.
Getting a closer look may be very tough. The site is largely surrounded by forest and the locomotive is at the far east end. If the current operator doesn't allow visitors, seeing the locomotive up close will be very difficult.
