Always wanted a Pennsylvania RR GG-1 for my all PRR loco roster. I just got a PWC version and it runs fine. All the TMCC and railsound features work. When I turn the sound down completely I hear a strange sound coming from inside the shell that can be best described as a popcorn machine. I have carefully lubricated it, however the noise still exists. Has anyone experienced this type of sound? I am going to call Lionel tech service, but before I do, I thought I would give the forum a shot.
Thanks, Sam
