Toy Steam Train (electric)

I wanted to try and design an electric toy train that my daughters figurines can ride in. The goal was it for to work with the wooden train tracks from Brio and IKEA. That works to some degree, but is still not perfect. So feel free to modify this design, maybe try creating some different wheels to make it not derail. In the meantime, I have designed some tracks that works perfectly with the train and carts. They are a bit deeper and not compatible with Brio or IKEA unfortunately.
