Horst asks others in the hobby for advice:

“I am installing a Peco Double Crossover Turnouts with electro frogs in my N-Scale Digitrax DCC layout without a reversing loop. (Parallel tracks only). My plan is to use two or four servo motors with decoders to operate the turnouts. Which components do I need to achieve a flawless operation including to electrify the two frogs alternately for the correct polarity?”
