Is there a precise technical explanation of the problem with 21V AC with Lionel products (which ones)?

The TIU Variable channels use the "chopped sinewave" method to scroll the track voltage up/down. This means the apparently "harmful" effects of 21V AC might still be present even if the variable channel is set to something less than full voltage.
