FYI: The issue with plastic gears lies SOLELY with the quality of the plastic material used to fabricate them. I have LGB engines that are several decades old with "plastic" gearing that still operate like the day they left the factory. The LGB gears were fabricated from high grade polymers such as BASF Luran S, which were more akin to engineering grade plastics, and these worked well even when meshed with brass or bronze gears. The QUALITY of the polymer resin (plastic) determines the strength and durability of any gear! Of course, proper lubrication with a high quality gear grease such as LGB, is also a factor in gear longevity!
