Got three loops of tracks running AND solved the nasty problem with one of the transformers being out of phase. You know...when you have to reverse the plug to change the polarity. Now I can run three trains independently and have them cross-over between loops. Tonight's action featured the SD-70 and SD-60 and an old American Flyer Atlatnic 4-4-2 (The 300 AC for those keeping score.)
Its starting to feel like a layout!
