I think I have created a lot more work than necessary for myself but what's done is done. I evidently misunderstood wiring for DCC. I have dropped track feeders after every third or fourth flex track section. But I insulated the track each time creating blocks that I don't need. I have just hooked up all the feeds to a temporary buss and everything works fine of course. Is there any need for the insulated gaps that I have used and is it OK to just leave them if not? I have over 150' of track down now. I just ordered an auto reverse unit for my turntable from Tony's on phone and he was confused when I told him about the blocks I have created.
