Dave, we spent so much time on all the versions of my layout plan, you remembered very well.
John, The lower town Dave mentioned (Parsons-Hendricks, WV) had logging and a tannery. Today there is a Kingsford charcoal plant. Thomas WV is at the top of the mountain and was basically a coal marshalling yard. Today there is Mount Storm Power Station where I worked in the '90s that took coal right from the mine until the correct grade of coal was mined out, now they bring it in from Cumberland the opposite direction from my section. Today the railroad is a rails to trails up the mountain from Parsons. It is ironic, that a forum member suggested this very railroad as a prototype the first few days after I started my topic, and I had already planned an HO layout of the same area I was familiar with back in the late '90-'00s.
Of course as Dave mentioned I had to do a lot of compression and trimming to fit it in an 11x11 room, but it is working out.
I like seeing your roundhouse and turntable on the peninsula by the double bridge. The only trouble is the yard is on the other side of the two mainlines. I know you are just trying to get the feel of doing some more advanced things with SCARM, but every variation you has the potential of making something click and lead to a great idea. I'm with Dave, Ilike the two routes and you can have trains going each way.
When are you hoping to start building benchwork? It won't be long now that the leaves will be down and we will have them cleaned up as best we can for the winter. (Dave doesn't get the privilege of raking leaves and shoveling snow any more.) It's a shame!
