David, I think your point is well taken about the possibility of voltage spikes when pressing the unloading or uncoupling buttons of the remote control track section.
I never ruined a circuit board in a modern locomotive for that reason, probably because I rarely use those remote control track features when running my trains. I only use them when I run my trains for children and other guests, and they love to see the Lionel Postwar operating cars do their tricks.
Even though I rarely activate these operating cars, it is very important to me that they are in good operating order so I can play the role of the Wizard of Oz, pressing buttons, pulling levers, and letting the kids and my guests do so when they see my layout. LOL, Arnold
