I suspect that since it moves at all, the electronics are ok.
It may be a mechanical problem. See if you can apply electricity to the unit without the wheels touching the track. If the train spins along happily, it’s likely that there is something loose in the chassis that is putting pressure on a gear or the worm and causing it to lock.
You may have to tighten a screw, or jam something in there to keep the engine block spaced properly.
