Rick O - thanks, but I’m confused. I didn’t see anywhere Lionel recommended running the Plug & Play Gateman at 12-14v.
In fact, the Plug and Play item is intended to ‘plug’ into a set like the Polar Express set, which comes with a wall wort at 18vdc. Or the set could be run off of a 180 brick (i.e., 18 vac).
If these voltages are too high, maybe this shouldn’t be marketed as a simple ‘Plug and Play’ as the Lionel videos depict.
