Well, I must thank you all for the fine comments.
Woodone - yes the plan is for the layout in the pictures. I originally removed the roundhouse from the plan but due to popular demand, I have revisited that idea and it has kind of grown on me so I put it back on the last shown plan.
Jesso - Once I did the barest minimum I could to the bridges, work on the canyon pretty much came to a halt. I was not sure what to do next and so I moved to the left end instead. I'm glad I did because now that I am going to add in another 3' just south of the canyon, things will change ever so slightly.
MadHatter - the Amtrak excursion up to the mine was a "spur" of the moment trip. There was a group of backpackers that came into town at the last moment and some fine young engineer jumped at the chance to pull a single coach up the old roadbed for a weekend campout.
Hey guys, I have a newer and more complete thread on this layout here...
