I agree with MtRR75 -- I don't think that the wye arrangement buys you anything except trading (in your picture) horizontal distance for vertical. Were it drawn to scale, I don't think it would take up any less space. The basic issue is still going to be the frog angle of the turnout at the apex of the wye.

As far as power routing turnouts, the manufacturer will usually say whether they are or not on the box. Generally, turnouts with insulated frogs are not power routing. Look and see if the frog is either non-conducting or insulated by small pieces of plastic.

Regarding your loss of power when loco crosses
through the crossover:

I don't see any wires going to the inner loop. Do you
have any power to it? The loco could be past the
point on the crossover where it can get power.

Set your multimeter to DC. Remove the loco.
Raise the power pack to run.
Run the probes along the rails of the crossover
where the loco stops. Where do you lose voltage?

Another possibility. The loco could be shorting out
the track if you have the polarity of the two
tracks different.

You can test that with your multimeter.
Put red probe on Right rail
of right track, black probe on the left rail.
Is reading positive or negative?

Do exactly the same on the left track. Did you
get a positive or negative reading? If different
from the right track you have the polarity reversed
on ONE of them. Reverse the wires to ONE of
the tracks and the loco should
run through the crossover without stopping.

That is exactly why the wye is being laid out that way. I don't have more than 2 feet of horizontal distance fit the 2 switches. I have 8+ feet for the other part of the wye.

I do not have power going to the inner loop. I will pull out my multimeter and see whether I have power or not. I will also check that the correct polarity is on the correct.

What changed? There was plenty of room in the original plan.

I do not want to be limited with what rolling stock I can use. Using a #4 switch limits me. So, now it is back to the drawing board.

Maybe not. Did you test it?

I did not. The hobby shop that sells the tracks and trains told me that if I want to run the longer cars like I plan, they may derail when trying to make the curve.

I trust that they are right. I plan to run the GO coaches. They are the longer cars.

Ah, so it's a general principles kind of thing. Best not to chance it.

Still, I have a IHC 2-8-2 that is supposed to run on 18" curves (in HO) and barely works on 22", while my Bachmann Spectrum heavyweights that are supposed to need 22" work just fine on 18".

Exactly.

Since I have the space, and since a crossover within a wye would look cool, I will do that.

Besides, did you always follow the first draft of your layout?
