After all this time, I think I should give a little update on what I'm doing. I'm installing control panels. The two small stations are getting Atlas controllers, but the large station is getting a full panel. I had help and finished wiring the panel (not hooked up to track yet) and last night started testing the connections. There were only 2 problems -- both push buttons. One of the dead end tracks had a normally closed button, and one of the others didn't work at all -- looks like we melted the button when soldering. Of course, it was in the middle of a string of 4.
