The new plan looks great, Mark.
I found these pictures and few others on this informative site on the Blackwater Canyon: http://www.wvbike.org/bct/history.html You probably know most of it or have been to the site, but I thought I would share with others that are interested. It is a great section of railroad to model and I think your plan will allow you to capture the essence of the railroad running through a beautiful section of God's creation.
