Steve,
I hope the "LGA" acronym I used does not stick ... for your sake!
Still, taking action now on getting the instant Airpax breakers. I just bought more TVS diodes for selected track points, and i will get the Bourns MF-R050 for 8 uncoupler/operating tracks and 8 uncouple tracks in my sidings for when I install them as I lay track.
I may even have to go to electrical trade school soon .
Thanks, Ken
