About this 3D model

2nd Attempt to my Toy Train engine to carry Lego Characters. This time, I added a Coal car as well that my kids turned into a Passenger car for Lego Characters :D Overall a great model and this time Pins for wheels are smaller diameter, so Wheels will turn. Plus pins have holes at the end so you can either print a 1.95mm Pin to lock wheels or use tiny zip ties so wheels will not come out. makes a great looking toy.
