I have two main lines that are controlled separately by power. If I want track 1 up only, I power it up...If I want track 2 up, I power it up only, and so on...from the same transformer (ZW).. Now I have added two fastrack switches, one to go to track 2 from track 1 and from track 2 to track 1.. Now when I power up track 1, track 2 comes up two. I want to keep both lines separate ...so do I undo the small wire under the switches 072, or is there any other way to keep both lines separate...So when I want to run a train from track 1 to track 2, I would have to power up both lines, and thats ok.....thanks
