If your MTHTrains Engine has no sound but the lights are on and it moves, check the volume pot on your locomotive. Turn it clockwise to the maximum volume.
What to do if my MTHTrains Engine doesn't work at all?
If your MTHTrains Engine isn't working, with no lights, sound, or movement when you apply power, try these steps: * Check if the track section has power using a voltmeter or a lit passenger car. * Slide the engine a few feet to bypass any bad track sections. * Ensure the track section isn't electrically isolated by a toggle switch or other device.
Why is my MTHTrains Engine making a crackling sound?
If your MTHTrains Engine is making a crackling sound, check the underside of the engine body for any screws or foreign material that may be lodged there.
