I need to wire my DCC layouts reverse loop. I have Bachmans reverse loop module. I have a main line running parallel to the reverse loop, both tracks have feeder wires going to the bus wire. Do I need a seperate bus wire for the reverse loop that connects to the primary bus at one point. In better words, if the reverse loop needs to be insulated from the rest of the layout, can I have feeder wires running from the loop to the bus wire serving the rest of thr layout? Hopefully someone can understand me and offer some help.
