Review on LEGO DUPLO Cargo Train 10875 - Battery-Powered Building Blocks Set, Top Engineering and STEM Toy for Toddlers (105 Pieces) by Agata Wielgosz ᠌

Son 2.1 assembles the rails, the locomotive itself turns it on, puts it on the rails and starts it up. Most of all he likes to open / close the crossing (from the additional set). In general, he does not yet collect "decorated" structures from Lego, so far only towers from cubes and cars where you need to connect the body and chassis. But as a game, he already likes it and he actively plays with it, again collecting rails. As many write, the rails slide on the laminate, especially when the road is small. But the son has already learned to hold the road when he launches. So it doesn't really interfere with the game. Control chips add interactivity to the game. All devices at home connected to it through the application, so everything works. It’s just not clear why it requires a GPS connection (it says that the standard requires it, but somehow the rest do without it). My son still plays like this and we haven't shown it to him yet. Older children and fathers who come to visit also like the road;) I think the price is a bit high when compared even with another hollow train. But I did not find alternative comparable roads for children under 5 years old.
