So...the comparing of the various options make it obvious that the Option 2 site is the only one even remotely able to suggest what the photos sent in show.  But a bit much of a project for the current budget both in time and resources.  But more interested than ever.  Send more please!  Was there a siding between the two tunnels?

In lieu of the KHPass I have put a box on the garage section large enough to do a loop.  I know of Tehachapi, Williams, Hook and Eye,  One more I can't think of.  Anyone know of a loop that might be useful to represent?

The two lines will remain for the moment with the back track hitting a grade about where the base of the loop will be.  The track leading to the loop is already an inch or so lower at the point of passing through the wall so the elevation difference and grade should be interesting.  Minimum radius could be as much as 20 inches and the loop could get oval a bit.......George Town Loop.

I think Norfolk Southern has/had a loop in the North Carolina area running east/west with coal...?
