Seems you guys got it all sorted out. The moral of the story, having the right formula is important when you start doing the math.
There seemed to be a lot of concern over voltage at the wall. A nominal 110 AC outlet has a ± 20v variation, or a range of 90-130v.
The average surge suppressor is designed for lightening strikes and other calamity, they will pass this low voltage variation as it's part of the distribution system design. I think a full fledged power conditioner is going to cost a bit more than an over sized train transformer.
Depending on the age the black plastic boxs are glued or sonic welded, grinding disk, followed with a razor blade, and then a little bit of force will get you in.
Given they are failing while in a display state, no one throttling them, My chief concern would be excess heat. Perhaps a fan on the less than adequate transformers(repaired of course), is less annoying than the Old tyco's buzz.
Along the lines of short circuits, intermittent open circuits cause spikes also. Inspecting the track junctions and tightening bad junctions or replacing track will help normalize things.
