I have this Baby K-4 in my collection. model#
and it’s made this static sound from day one. I sent it to Lionel and they said it’s a normal part of the sound track For the engine. Some how I don’t believe it because when I mute the chuff I don’t hear it at all but when I ring the bell or horn I hear the static again until the sound stops. Any clue what’s causing this or how to fix? My guess is some kind of short. I pop the hood already to check for obvious wire issues but that doesn’t mean I didn’t miss something obvious to you seasoned pros.
