American Flyer Steam Locomotives, like the 21165, entirely used worm drive motors. The advantage of worm drive motors is that they allowed the model train to start slowly without being lurchy. Effectively a smoother start as the engineer provided power made for a more realistic toy train model experience. In addition, worm drive motors enable the locomotives to pull longer trains.
