We immediately bought another set with arrows and additional elements. Then we bought more additional items. Two boxes. We are planning another set of arrows. Then at least something complex and interesting can be built. It is also a pity that there is no hollow railway bridge like in Lego. And of course, Lego is Lego. Quality, but expensive. Pros: The headlights are on, the speed is changing, the child is happy. Cons: There are very few rails in the kit, it is worth immediately budgeting 2-3 additional sets of the road itself.
