I had a similar problem on a Polar Express Trainsounds Tender that kept blowing the whistle repeatedly. I ultimately had to change out the sound board which fixed it. After you do all the cleaning you signed yourself up for, next remove the sound board and then extract the sound chip using the correct tool (no picks or jeweler's screwdriver). That can reduce resistance (corrosion build up) on the pin connectors. The shells come off and back on these F3's pretty easily.
