Thank you! I'm glad you like it :)

Thank you for the kind words! The trains are specially scaled to fit Lego figures (because practically every child has them :) ). However, I designed the tracks for my own, independent and slightly more complex system, so it will not fit the Lego tracks. However, if you would like to put both solutions next to each other, visually it should look OK.

I thought about it, but I prefer to design because it gives me the most fun :)

Probably not, kids today have plenty of toys with motors. I see that they have much more fun when they can move the trains with their hands (it also develops manual skills). I observe this every time during workshops with children, where I test all my models. But I can still change my mind - I didn't want to design the tracks at first, but now there is a whole system of them :)
