Sorry, I thought everyone remembered from my first posts that this is an N scale layout. I get in my own little world sometimes!
It's going to be a proto-freelance RR (The Greater Rhode Island Maine Railway, or the G.R.I.M.), based upon a fictional merger of B&M, MC and the Old Colony & Newport. so one level (the one you see) is Maine, and the planned upper is going to be Newport Rhode Island. (I know this has little to do with the subject, but did you ever know a railroader who didn't want to babble about his railroad?)
Of course this looks
vastly different from the WR&N - I couldn't find any way to work the WR&N's layout in any way, shape or form into my layout. So, I had to start with working my track desires, and a loop railroad with passing sidings. This track plan is my own attempt. I included that so everyone could understand how I got to this present spot.
Mine is 8 feet by 5, and the islands are 32" (north) and 29.5" (south). This was the only way to work it into the room, so bench-work was a first priority.
I tried to work it with 12.5" curves (that would be 24" in HO) as I was hoping to work in passenger operations. Alas, almost every curve at 12.5 could not fit the layout, so I had to reduce it to 11.5" (roughly 22" in HO), which means passenger may still be an option, but I doubt it. The south edge (Snowshoe Curve) is against a wall...
...so passenger cars may well bang into that wall as they swing the curve. The deep corner is actually curved away from the wall to prevent that, but I just kept banging my head into the space issue.
The north island is going to be a bridge I'm going to have to scratch-build, since it curves (why? Because I managed to stick a turnout into almost every straight run of track!)
I'm going to do at least one short elevated track (the mountain route), two bridges, one tunnel section (the back wall straightaway). The hidden staging is of course New York and New Haven and Boston and... well, anywhere else I need to deliver to.
I've got a lot of scenery ideas, as you can tell... I'm just trying to second guess myself to make sure I'm not going to be limited when I start doing operations.
Everyone's giving some great feedback, including a past suggestion I make the mountain top removable for when the trains derail inside the tunnel!
