Two Deck Redesign
So after various thought on the ideas and questions raised, and considering my goals for the layout, I have put together a two deck redesign. First, my guiding thoughts that went into the redesign:
Themes: There are two themes
1) Route 302 in NH past Frankenstein trestle and Crawford Notch. That is the central aspect to basing this on a real railroad. I love that part of NH, have spent much time in my life with the natural beauty there, and love seeing the trestle and the trains, mostly in recent years the Conway Scenic Railroad.
2) Variety: While basing this on some real railroads, and using them as a guide to some reasonably realistic track and operations patterns, my version of fun in the hobby (we each have our own version of this being 'fun') is variety in many forms: continuous running, operations, multiple trains running at once, long enough trains to cause family and friends and grandkids to get excited, modelling scenic vistas, representing towns in the 1950s, doing the wiring, showing off a model railroad that offers enough that is recognizable to spark conversation. It will be DCC and I hope someday to program running it from my computer. I have been in the software industry for over 30 years and can program circles around most developers, so I will geek out a bit on tat end over time, especially if I do expand shelf layouts throughout the house later. I am not a fine craftsman, in my modelling. I admire the craftsmanship of those who are, but I know I am not. My scenic vistas I know come out very well. But buildings, etc., I know will be more of a challenge. I may never build my own rolling stock by hand, and I doubt I will ever hand-lay track. But I will finish the scenes, weather buildings and trains, create realistic looking water scenes, and definitely roads such as route 302 and others. I won't be measuring it against the craftsmanship of others, but against my own improvement over time and the fun I have running trains with family and friends.
I don't know if those qualify as 'themes' in the sense that the question got asked, but I hope it gives a flavor of why I do this. So that said, I realized I do want operations to be able to be based on how the trains got operated when not just playing around, and would hope there is enough interest and challenge that I can attract occasional other model railroaders to an op session from time to time (another manager at work's husband is part of a small group that go house to house sometimes for operating sessions.) So I definitely am doing N scale and went to two decks and lengthened all of the yards while adding more tracks in the yards. I added the turntable at Conway. I ditched Whitefield and Cumberland Mills and instead added a portion of Portland, ME at one end, Gilman, VT at the other, plus a little side jaunt from Conway down to the sidings in Ossipee, NH.
Below are the two diagrams of the two decks. If the print isn't legible enough at the top near Conway, it says that topmost siding in the lower deck image is my access to the staging that will be underneath the lower deck. I also connected both decks across the walkway to the helix. Current thinking is single helix but it would not be hard to make it double. Helix uses a 20" radius since going up would use Helpers from Bartlett climbing up to Frankenstein Trestle and Crawford notch. I couldn't find what the Crawford notch track arrangement was in the 1950s, so for now I show only a single siding along the main track since that is what is still visible from Google earth.
Given my goals above, I'd love to get one last round of feedback of potential issues or suggestions. Hopefully the context I provided above helps with assessing what sort of things to point out. I am very interested in if I missed key track features at Crawford north that would be worth considering. Same at Gilman, VT, though I have limited room there and want to put in the paper mill by the tracks.
I still hope to be able to start demolition of the old HO layout the weekend of august 24th and 25th depending on life's curveballs.
Thank you again to everyone who has been helping me sort through my thoughts and avoid any particularly bad pitfalls.
