Wireframe is in the tool bar at the top of the screen. White Rectangle.
Now for the good part. I clicked on it and the track and a coal mine were all that was remaining! That was correct. BUT, there were no consists. Looked under ground and from above. Based on that I am not sure I would use that setting in a nice new yard with lots of "things". I do not see anything missing on the route.
THANKS for the tip.....
As Jack Nicholson said: I AM BACK! The buried consists only appear in a search when in a Session. Seems to make sense. So, my little graveyard remains. If it does not cause any other issues "leave em buried". But does it cause issues? I have some issues with a session that blows an engine horn for two events. It works. Shut down and restart later and the horn will not sound. I'll blame it on the ghosts of the buried.
