I have a Lionel F3 6-24529 (6-24530) that is having a problem. While it is running the sound will sometimes stop working, then it will come back on. All other things seem to work fine, lights, smoke, forward, reverse, etc. Any ideas on what might be causing this? I don’t have any test equipment so this might require a trip to “The Train Doctor”. As I stated this is a intermittent problem.
