PLEASE forgive my ignorance but I haven't been in the model railroad game for almost 20 years and am ready to get going on a basement set up, but, I have some questions. What is DCC? What are the best resources to learn wiring and track layout? Whats best...a DC, DCC or AC set up? Its funny, I fly very sophisticated airplanes for a living yet this whole wiring and track set-up stuff sounds like Greek to me. Any help would be greatly appreciated.
