C&O's Mountain sub-division actually ran from Charlottsville, Virginia, to Clifton Forge, Virginia. It was a portion of the Clifton Forge Division, which included five sub-divisions. Mountain, James River, Alleghany, Hot Springs, and Greenbrier. Although I don't know of a specific plan for the Mountain sub, I recommend you contact the Chesapeake and Ohio Historical Society. C&OHS has timetables and track charts available for purchase that would be very helpful in your layout planning. http://www.cohs.org/
