OK...the question here is what half of he signal is missing or compromised. Is the house wiring ground conductively coupled to the dirt earth outside enough to effect a significant capacitive short of the house wiring ground to the transformer U output (which is connected to the outside rails of the track which is setting on the ground). I think that is questionable, but running a house wiring ground wire over the track (or maybe near it somehow, but not on the ground) will prove something.

GRJ’s Dale M Booster is always welcome on any layout and may be the answer with a stronger signal with a lower source impedance if the track is truly effectively setting on the house wiring ground signal.

Also, New Haven Joe, what do you mean by “common” on the transformer? The U terminal? I don’t see how that would help, and might harm. If you mean the ground pin on the transformer plug, that might help but violates the wiring code having two ground rods, the one by the meter and the one you put in the ground. But the wire going from the transformer ac plug ground pin to the new ground rod might be enough ground wire signal to make a difference. I just would not use the ground rod. Maybe attach it to a stick near the layout.
