Mike, I hope you realize you have some reverse ("S") curves in this design (2 with the O64 turnouts and 2 with the O72 curves) and I don't know how these will affect operation. Since this design uses Ross components, you can swap out the O64 turnouts for #4 turnouts and mitigate the effects of the 2 reverse curves at the turnouts. You could also mitigate the effects of the others by using flextrack instead of the O72 curves, but that would involve fitting/cutting. I tried using larger standard curves, but they didn't fit because of their size. I don't think any of these will cause any real problems, but then I don't know what equipment you intend to run or how fast and I felt I needed to mention it.
Anyway, here is the same design using #4 turnouts for you to compare. The differences are subtle, but there doesn't seem to be any cost difference. Please note that Ross turnouts don't automatically come with remote control. Ross offers 2 Ross-Ready remote options, Dz1000 and Dz2500, so you have to consider the higher cost of those if you are comparing prices to other brands. I don't know the difference between the 2 remote switches.
In case you don't know, standard turnouts have a curved diverging track while numbered turnout have a straight diverging track. The only curved part is at the points that switch between the straight through track and the diverging track. The effect is basically the same as if you have added a straight track between the standard turnout and the first curve, thereby eliminating the reverse effect when the train moves through the turnout to the siding.
FWIW, the #4 turnout is pretty much equal to an O72 turnout as far as the points curve is concerned, but allows you to choose between 3 widths for a transition track (3.5", 4" and 4.5"). In this case, I chose 3.5" so the siding tracks are further from the wall. The width between the main and siding is the most obvious difference. I tried 4" and 4.5" transitions and they don't fit, so you're choices are pretty much limited to these 2 designs. I suspect some will say that it will be better to use the O64 design because the siding in the #4 design is too close to the main for trains to pass safely, especially on the curves, and I wouldn't disagree with such an assessment.
I hope I'm not complicating things for you, I'm just trying to give you all the options. I felt we unduly influenced your choice of track, but then I've also tried converting this design to Atlas, GarGraves, Lionel and ScaleTrax with no luck, and I must admit I'm surprised. The problem is the lack of the same turnout/curve options.
