Yeh, as far as I am concerned it could still be NG and the OLC, or not. I had the thought that if the resolution was sufficient, the vehicle on the road could be a clue because if the vehicle was anything later than mid 1940's it would have to be somewhere else. I was not able to tell anything about the vehicle however. The place where I looked at a bent piece of rail was a spot where the line ran right up against the road as in this photo, but there was more small brushy trees as I recall. 50 years of growth of vegetation could account for that.
