Reply to "3 Rail DCC O vs 2 Rail DCC O"

To That question, I can't think of any other than the wiring issue for reverse loops.

With 3 rail, one side of the circuit (AC or DC) is on the center rail and one side is on the outside rails. You only need one outside rail for a complete circuit, so many modelers use the other for signaling and detection and whatnot
