I have a few of the 2-8-0 consolidations. I have two that don't run silently. The only way I can describe them is that when they run they make like a whirring noise . I have not done a thing to the nylon gears or belt. Just very annoying to hear this noise. It seems to get louder when going around the curves and also under load.
I have tried lubricating with grease, but still no go .
