Being the post-Christmas blitz, I've been developing possible track plans using Kato's Unitrack system. For a newbie like me, it's been great, because I can set up and take down possible track configurations and arrangements as easily as I change my socks. I can see what works, and what doesn't... As a post-Christmas gift, I received the WX310 Double Crossover track I have noted that one distinct possibility is that I could simulate a double-track mainline by using a Dogbone pattern... It also allows for a crossover that could effectively function as a reversing loop. My question is how this might be done with this particular track unit and DCC? I know that the scissors crossover unit is pretty much insulated across all the centre connections. Only the two outside rails remain unbroken as far as power is concerned. I know there is some sort of stationary decoder that handles this automatically... what is necessary for this?
