issues

Hi my mantua Hudson's piot truck keeps jumping the track how do I fix that? The wheels dont seem to have a flat spot and it only happens in curves and no where else on the track I was thinking about kit bashing riva rossi trucks to it since my friend did that to his and it made it better Tia jake.

Hi there i have a rivarossi 2-8-8-2 and it has electrical pick up issues i cleaned the track and the tender wheels going to clean the locomotives wheels and see if that helps any helpfull tips appreciated

I just installed a DCC Decoder in my GP-38, that I took from another GP-38. It runs fine, and the headlights come on, but when I'm going forward, the back comes on, and when going backwards the front comes on! How do I stop this from happening and fix it to how it should be? Any help would be...
