SO basically I have two "bus" wires under my table, and every few feet i basically got two smaller wires (one for each bus) going to each rail through a hole in my roadbed and wood? How do I hide the hole anyway? Does this sound right? I also heard to NOT connect the buses when they reach the other end (not make a loop) right? Here we go this is what im looking for... Does the digitrax zephyr have extra AC terminals so I can hookup a switch tontrol box?
