Flossman,
You said the magic word, simply. IMO FasTrack with the Command Control switches are seriously simple, and the switches operate remotely from either the Legacy or TMCC remote controllers. You can run as many as 99 FTCC Switches from track power, that is as simple as it gets and it works very very well.
