The Retro remote set with smoke function and driving sounds as well as the included tracks are on offer for children from 5 years old. The toy is powered by a 3.7 V type battery (included), a remote control of 2 x AA 1.5 V batteries (not included). We install batteries in the coal wagon. While driving, the locomotive emits smoke from the chimney (having previously supplemented it with water - a water dropper included in the kit), the light installed at the front additionally lights up. The tracks have a simple connection type, which makes them safe and durable to use. Using the remote control, we can control the movement of the queue, its direction, speed, steam function, sounds.
