RickO posted:I recently spotted some noticeable bushing wear on the upper shaft of one of my older legacy locos. I hope Red N Tacky isn't doing as much harm as it is good.
After doing some Internet searching.
Red n Tacky is an EP (extreme pressure) grease with a "high level of EP additives".
These EP additives contain sulphur which will attack brass and bronze components.

Experts please tell me this doesn't apply. Every loco I have has Red n Tacky in the gearbox.
Unfortunately I think you have the answer in your research.
