Quote from: Loco Bill Canelos on July 28, 2024, 08:57:18 AMThere are no metal gears available for the older 4-6-0 Standard Locomotive,True, but Jiro Yeramian makes Delrin replacements for several of the final drive gears. Contact him at girotek@rcn.com.
As Jay says, your best bet is to find someone at the local RR club who would be happy to help swap the gears. It's not a big job. Check out this thread.
