Can anyone recommend a simple, online, how-to guide to wiring a layout for DCC? I am considering a major overhaul on my layout which will convert it from Kato Unitrack (pre-wired feeders) to flex track. This will require that I learn a few new things, which is always a good thing. However, while many of the online guides, such as "Wiring for DCC" and "DCC Concepts" are informative, they tend to read like a dissertation. My eyes burn and my brain sizzles before I get to the basic information I seek. At this point, I am looking for "how" instruction as opposed to the "why."
