rehunn,
The other engines you refer to were indeed there also, but in a different scrap yard on the south side of the mainline not far from the other one. We ventured in there and it was a tangled web of vines, and some engines were elevated on some ramp track. I think some trees were growing through some engines as well. I did not take any photos for some reason. Several of these engines have been saved however. I think they call them the "Lost engines of Roanoke" or some such if you want to google it.
