Hello, I’m new to the O gauge trains and recently bought a 2018 Lionel Ac6000. It is item # 6-84852. My question is all sounds work fine and it moves forward and backwards but does not rev up and down with throttle. It’s blue tooth and I do run it off my phone. Is there something I’m missing? I’ve adjusted the volume on the app for engine sounds and chuffing but nothing changes. Any help would be appreciated. I’ve ran ho for years but just started O gauge.
