I would suggest two experiments to help identify the problem:
a) A section of track where the ballast between the rails is not glued, but the shoulder ballast is. There would be considerable wicking thereby failing to yield a consistent result. Sounds simpler then reality.
b) Another section where the ballast is not glued at all. That would be potentially to messy, easily predictable and not desired.
Which particular S. Express ballast are you using [ part number ] ? #20 premier blend. How would grade selection affect sound level?
Edited to add: What brand of flex track are you using on the ballasted section ? Atlas and Micro Eng same sound both. How would different track would impact sound levels??
Again: anyone conquer running noise after switching to all metal wheels? Plastic wheels are quieter but attract dirt buildup and have higher rolling resistance. Anyone want 300 plastic wheel sets, they are going out with the trash today?
