Okay, big sigh, another fairly dumb question, here. Hopefully, for which, I can adequately articulate the information I actually need. Bear with me; I tend to learn by doing and, while I absorb information pretty readily, I can often be woefully dense with regard to things that present as fairly obvious to others. My specific question is around use of a double-crossover turnout, specifically the Rokuhan R078. I am going to use this crossover to connect two basic ovals, an inner and an outer. My intention is to leave it in power-routing mode, but I have to admit that my understanding of what functionality that results in is vague, to me. Rather than go into a lot of detail about how I picture it working, and what I'm expecting, I'll just ask the question in the way that expresses the confusion in my head: If I have two power controllers, one for each oval, when/where does power from one controller stop, and the other pick-up, when I have the crossover switched "on?" E.g., I'm running a train along the outer oval and I want to switch over to the inner... Along comes my train, and it makes the crossover, heading toward the inner oval... At what point is the locomotive no longer powered from the outer oval, and is now running on power delivered from the inner oval's controller? My gut feeling here is that this is something very basic and obvious, and (as is my tendency) I'm just overthinking it.
