I finally got there. Two trains running together and not requiring any user intervention. The outer loop was easy, but the inner loop is two independent reverse loops tied together. To make this work without my activating turnouts, I used the DCCConcepts LM-iD to sense when a train is getting close to the turnout, which then toggles the Cobalt IP Digital which is the turnout point motor. This was the magic sauce. It works great too, and didn't take too long to wire up.
