“Our club is replacing our HO turntable with the Walthers 130′ one. We have arrival and departure and 39 stall tracks. Our trouble is the auto polarity reverser built into the pit. Being that the built-in reverser is set 180 deg. in the pit, only half of the tracks work as needed but the other half end up being reverse polarity. My question is, can we wire a Digitrax AR1 into the feed to the bridge and let it do its thing?”
