Yes, I solved the reset with a smart switch. Just need to add a Pico remote to control it instead of having to use my phone or Siri.
The low voltage problem is evident on the VL freight's electro-couplers, which were the whole reason to switch to AC. First attempt resulted in smoke when I had it turned down to 66% or so. I didn't measure the actual voltage.
Probably going to bring the wall-wart out, and stow the 990/cab2 and VL freight when the boys are here and give them a lot more freedom to smash and grab.
