Reply to "Two rail reverse loop"

Mark,

Ok I have read that article several times and have not fully digested its info. More questions. Since I will be incorporating 2 train operations in the future, and want to wire for that situation, I’m confused about a couple things: What determines using a D2T 2w vs 3w relay? I assumed a 2w cause it’s a 2 rail. Does not the MTH Z1000 put ac power to the 2 rails? If 2 trains are running at the same time, when the IR detector swaps polarity as the first train is emerging from the loop, how is the other train isolated from the swap of polarity? I'm close but not quite there yet
