I hadn't thought about the overhead wire clearance, thanks for bringing that up. I originally not had the switch back, and had the run simply echo the CV line, but changed it as the prototype ran that way. i may go back, I'm pretty concerend about the potential grade.
I'm planning the main deck to be 3 feet wide, and the upper 2.
Maybe a helix is the way to go here after all.
I'm trying to model 1956, not live in it.

There are many traffic sources along the route, none of which seem to be represented other then the defunct line to Stowe. Montpelier junction would fit nicely in that corner. With the small wye that only has room for turning an engine and one car, etc.

I realize that this is not the entire run, we're doing a bit of compression here. What isn't planned out is the other side of the room, this is just half of the run as shown.
Over all the space is approximately 16 x 20, but I don't want or desire a layout in the entire space. I need to configure a work area, and a central open table for gaming. My concept is to really just model the interchange in waterbury with the MMER, I'm not looking to do the entire run, sorry if I didn't make that clear. I would like to do this half first, and than add the other half with the WRJ yard for operational fun later, and join the two halves with a removable section.
Your idea of putting Montpelier Jct. though still works, and is a good one.

Even though my test layout isn't done..
Even though the room the final one is going into isn't finished...
(It's ok to dream, can't I?)
I've drawn up some rough plans for one side of the final layout. I'd appreciate honest feedback, this is a first draft.
I am planning on a 3 level (two visable, one staging) layout for this side, as I want to build the Central Vermont from Waterbury, VT to White River Jct. VT. Additonally, I want to do the Mt. Mansfield Electic Railway that interchanged with the CV in Waterbury, and ran to stowe up until 1932-3. I plan on not being super historical; I do want to run equpiment up until 1960's or so on the CV main line (the main level).
I'm aware that without a helix, the grades up and down levels may be too steep. The MMER never ran more than a single car, or a box cab with one or two cars in tow, so the grade behind the wall (and yes, that space is accessble) can be kind of high.
I should add that min. radius for the CV is 22 inches, HO scale, and the MMER, 18 (also HO scale)
Ok, enough background, fire away!.
sub level (staging)
mid level (grid is 12 inches)
upper level
