Biggie Smalls the Train

Here is the completed Biggie Smalls the Train train with attached wooden wheels and everything. Oliver actually found the toy quite amusing, saying "car" when he say it.

I have two new goals regarding this toy. I want to 1) make a Totoro cat bus version and 2) create one that will fit on a wooden railway set (you know, the Brio kind). I've measured those tracks out and the distance between track grooves is 20mm (about 0.8"). I don't think this 2" block will fit properly nor will its weight distribute well without doing some wood routing on the inside to store the wheel mechanism (which I don't have the tools to do). So I'll need to figure something out with the 1" blocks or need to purchase 0.75" blocks to make the trains.

Much planning!
