Mine just came in ... the front roller assy was loose but thankfully the screw was also in the bag.
When I turn the power to the track no sound.
When I turn on the remote, no sound ... checked volume is all the way up.
Crew talk, horn and bell are working.
The pilot barely clears the center rail.
The big issue I have is a death wobble on the front trucks so bad that it derails.
Check the on/off switch located on the bottom of the engine. Mine had a wobble on the rear truck…but haven’t experienced a derailment.
