This is kind of hard to explain/word it so i will try my best. When I was younger I remember getting trainsets and you simply assembled the track (an oval) attached wires from a blue box to a curved re-railer piece of track and then plugged the blue unit into the wall and that provided power and control for your locotmotive. Now for mylayout i have chosen to use DCC and I do realize how expensive it can be but I want to run more than one locomotive at a time. I have chosen the Bachman EZ-Command DCC system. Finally heres my question . Besides the DCC controller, what else do i need to provide POWER to my track, does the DCC controller do this or do I need to purchase some sort of small tranformer that plugs into the wall? I am just really confused with the whole wiring and supplying power to a layout, I understand that things have to be wired a certain way with turnouts, and reverse loops and all of that but exactly where do I wire my layout to provide adequate power, I mean do you solder wires to the rails in intervals? I understand this is a large question, but any help would be DEEPLY APPRECIATED. Thanks again.
