て、一層の運転の楽しみが得られる。 There is play in the meshing of gears from gear 12 to gear 19, and due to this play, each driving wheel gear 1
2, 15, and 19 can move up and down, and as a result, each driving wheel 6 can move up and down via the driving wheel shaft 5. Therefore, when the locomotive is running, each driving wheel is in close contact with the rail at all times, allowing smooth running and preventing derailment and generation of noise. In addition, since each driving wheel moves up and down relative to the truck, it is even more enjoyable to drive than the conventional fixed type.
