After a few years absence, I am back into the hobby. Please excuse what to many may be simple questions, but this DCC is getting a little confusing. Give me a tube amplifier to fix, a horse to shoe no problem, but DCC! (when I was born, the family bought its first TV – black and white). The last time I built a layout was over 25 years ago and it was DC. I have read a bit on the net, and there are many different suggestions about wiring etc.. I was at a model railway show recently, and I spoke to an N club representative. He advised that the club does not modify any turnouts and insulated rail joiners are not necessary except for power districts. The club show layout uses both Peco (Electofrog and Insulfrog) and Atlas turnouts. I am following an article in MR “How to Build Realistic Reliable Track – Smooth running on N scale track” as a resource for track laying. I am using Atlas flex with Peco Electrofrog turnouts and have a few Insulfrog turnouts as well. I am puzzled about when to use insulated rail joiners, and if any turnout modifications are needed. And do I have to modify Peco crossing track? Can anyone, who has done track laying etc., advise me of their experience and what has worked for them. Any other hints you may have would be appreciated. Thanks in advance to those who respond.
