Hi Rob,
?
It's challenging to analyze complex layouts that are compressed into a single drawing.? I do see the crossover in sections 9-10.? Make 1-8 a reversing section, in addition to the reversing section I mentioned the other day and you will be fine.
?
I don't know what scale your layout is.? If HO or larger, three boosters would probably be good if you have them.? If you yard area will have a lot of idling locos, it might be on one booster.? Everything to the left of it could be a second booster and everything to the right could be a third.
?
If your turntable is a Walthers, it has mechanical reverser.? If all the tracks entering it have the same polarity, you won't need to add an electronic reverser.? If they don't have the same polarity, you will need to add an electronic reversers.? See my book, "DCC and Model Railroading" and the reversing sections of my website,
