Firstly, thanks again for the comments & Q's. Some answers (and probably more Q's) follow;
Original reason you gave for including a wye was "This got me thinking I could get one in "somewhere" and thereby substantially increase "operating interest" (hopefully?)".
What was the "operating interest" you wanted to include?
Turning an engine? A small turntable takes less room than a wye.
Turning engines certainly has its appeal and I would think (but this is why I'm asking!) would add a lot of "switching moves" - Making up (albeit little) trains and dropping off/picking up cars as I go is something I want to do. I'm also pretty sure that the majority of the time I'll be operating alone and only very occasionally with someone else. A steep grade and short passing sidings requiring "saw-by" moves and/or splitting the train to make the grade is another "approach" I've been bouncing around.
OTOH, I don't want to turn it into an unsolveable puzzle running in a spaghetti bowl - Which is what I think I'm getting close to with the wye...... A turntable could certainly do the trick, but space remains tight and I don't know if it's even warranted.
What else did you want from your wye? Alternate routes through the layout? Do you have room to add more tracks without turning it into Spaghetti Junction, considering that you also want to have room for the slot(?) cars?
Yep - Race cars (and the featured grade crossing at Gold Hill) remain one of the definite "givens". I don't think there's much room for alternate routes, unless a *lot* of it gets buried in tunnels, which I'm not sure about either.
Most of us (very much including me) get carried away, and try to squeeze more and more. Whether adding a wye really is an enhancement depends on what your current goals are.
+1 on the first part - I too must certainly plead guilty to that "trap"! In fact, looking at it more, I just don't like it - I don't like it parked right in the middle - I was just kinda thinking aloud, but think I've changed my mind, again.....
"Current goals" - Hmmm - FWIW, the prototype is a simple short line that doesn't have (today) any way to turn trains - One way they pull the tourists from Virginia City (the highest point, in my mind located at the top right) down to Carson City - Probably located in bottom left (where you had the depot originally!) Then they get pushed back up the hill.... However, there used to be a turntable (and a big shop) in Carson - Maybe that should be out in the "peninsula"?
Along the way, they pass thru Gold Hill, which IIRC actually has just a single siding in addition to the grade crossing - This could be expanded a little.
As noted before, we're set slightly in the future and gold & silver mining has made a comeback, warranting more trains moving "stuff" rather than simply passengers - Lumber going to the mine(s), ore coming out and going to a smelter - A possible armored "special" coming out hauling gold to Carson is another possibility. Regular freight service between the 3 main locations..... [Probably way too much squeezed in here of course!]
I have a little string of tiny ore cars for the mine - We need to grab those and transfer to real cars for the trip (?) is another idea.
While not a rivet counter, I want the three "main scenes" (V. City, Gold Hill and "the end of the line" (maybe down by the river rather than all the way to Carson?) to be "recognizable" - Most of my buddies are very familiar with the area and I know I can "suggest" these locations pretty well. [V.C. has a beautifully restored school & opera house, Gold Hill the crossing and the oldest hotel in Nevada. Mines & smelters still exist etc......
If V.C. stays at top right the car track will loop around the RR at top right - Main Street (F Street IIRC) can be suggested by flats behind the car track on the long wall at the back - This rises slightly while the RR descends before going in to a tunnel in order to "escape" from within the car track.
It's after that I don't know where to go next, but I have somewhat returned to your original idea! - I'm not even sure my "figure 8" version is any good any more
I like that it runs *thru* rather than around the layout, but beyond that have (once again) gone to an almost blank computer screen.....
Thanks again for sticking with me on this!
Cheers,
Ian
PS - I'm now getting the hang of Xtrakcad! - On my version (Linux) it does occasionally "lose it's mind" (ability to connect tracks) - I've now pretty much concluded a restart (and regular saves) is the way to get it behaving again - Frustration level is receding quickly!
