DCC and reversing loops

[Anonymous]

If you are using DCC the rest of the railroad does not reverse polarity. Only the isolated reversing track changes polarity, but unlike DC the locomotive keeps going in the same direction (controlled by its decoder, not track polarity).

The DC method requires a polarity change on the block that the locomotive will be entering AFTER leaving the isolated reversing track. This could be the entire railroad, but if broken up into several blocks only the following block need be reversed, and of course successive blocks as the loco reaches them. Other locos on other blocks will not be reversed.

I am just reentering the hobby and have decided that the quickest way to have a working layout is to build the Woodland Scenics, Grand Valley, "layout in a box" (or several boxes). With an eye to the future, I have decided to make several modifications to the track plan, one of which is a crossover that connects the outer loop to the inner loop thus creating a reversing loop. The Atlas customer service office says I should just buy a reversing module and install it by following directions. I guess I can take this step but I still don't understand how this will work. This isn't a simple reverse loop as explained in all of the literature. When my locomotive crosses the track gaps, the whole layout will change polarity if I understand how reversing modules are supposed to work. What will happen to any other locomotive operating elsewhere on the layout?

I'm sure I am not the first person to have this problem. Can someone help me? I would love to hear from you.
