I recently started running my 3rd Rail J-3 Hudson that I had upgraded to PS3 last year, pulling about 7 Golden Gate Depot ESE cars. The drive gears got completely worn off. Anyone on here who can source the gears and replace them?
I think a big part of the problem was that I did not clean the grease out of this old gearbox, and the gearbox lid was loose. I was too focused on the electronics and didn't give the drive system the attention it deserved, lesson learned!
