I just received a new on30 Forney and found a rather noisy (buzzing) sound when slowly starting to move. If I hold the tender or put resistance the sound goes away. Seems like some part vibration. I am planning to install sound so I removed the tender housing and ran it. Buzzing still occurred. sound seems to be coming from the rear (tender area)
Any help? has this been a common problem?
Run it on regular dc if the noise goes away it's from the motor, some decoder settings can eliminate most of the buzz...

After trying it on DC, try to swap decoders. For whatever reason I've found the stock decoders are sometimes good, sometimes bad. Oddly swapping a "buzzing" decoder into a different engine works wonders, and vice versa.
My new forney buzzes as well, and I'll be picking up a new decoder at Trainfest this weekend to swap into it. I'm confident that will solve the issue.

I can totally agree with you, changing decoders can be a solution, it happens wwith other manufacturers locos in different scales so its not an uncommon problem, It is strange though how the 'rogue' decoder performs fine when used in another loco!
Sometimes the decoder just syncs better with the motor, I found purely by accident that swapping the motor leads around then changing the direction in the decoder can make a difference in how smooth the motor runs, might be something to do with how the armature is clocked in relationship to the magnets...
