This is my first post, so please bear with me. Just picked up a Lionel #6-8665/#6-9176 BAR Jeremiah O'Brien with caboose. It's only been out of the box for display and has never run, as far as I know. The reverse unit is so loud, especially at lower speed. What can be done about the "buzzing"?
Also, the contact roller on the caboose is very loose causing the light to flicker. Is it supposed to have some tension on it? Right now, gravity is the only thing making it contact the rail.
