It has a very good working power with eight wheels per car or loco and its articulation system enables it to negotiate curves very well, even the most tight. We obviously can insert in a convoy with an electric locomotive, but in this case only two cars on the three (one must-train for reasons of polarity of the magnets grip). The weight of these elements will be as damaging as the Brio locos are very powerful.
Too bad the Brio toys do not have all the qualities of this aesthetic process, ecological, solid and effective.
