Allan - disconnected all auto reverser wires and the humming stopped. Don't know if this means there could be a fault in the AR or elsewhere.? I do not have electronic circuit breakers installed.

Ted,

You said you disconnected the reverser.? Was it disconnected when you got the faint buzzer sound?? Do you have an electronic circuit breakers installed?

The buzzers are very sensitive.? They will sound even when you have a "high" resistance.? I haven't done a detailed study as to what will trigger them, but I think they will still make a sound with several thousand ohms in the track circuit.? If you have auto reversers, electronic circuit breakers, or frog juicers, I think these all may cause your buzzer to sound.

The bottom line is that a high resistance will not inhibit your train from running.? So there is no need to worry about a faint buzzer sound as long as your train is running fine on the track in question.
