I have a blue box Athearn gp 30 35 38 or 40 that was gave to me that has an odd noise when running in one direction only you can barely hear it without the shell put the shell on and its louder , i think that the shell is just acting as a amplifier checked gears and they seem fine wheels axles are tight in the gears. so, I'm at wits end anyone have any ideas?
