Did you see my thread on my new H-10? I can tell you why a lot of the stuff you observe is happening!
New Lionel H10 must have been assembled with power tools!

And when you're done there, note that there is also a problem with the software of the Railsounds board, it has to go back to Lionel to load the proper level sound file. The original shipment sound boards would cut out after a few minutes of full volume running, especially if you cranked the labor up and tooted the whistle a couple of times. The issue was the new sound engineer loaded the sounds at too high a level, and it's overloading the output amplifier.
