Wood Rollercoaster Train scale model

thingiverse

I built a scale model rollercoaster train to operate on a wooden rollercoaster track. This design was created to function as an actual working model. Each rollercoaster car has a servo motor onboard to control the harnesses. Currently, the gears don't fit properly and need to be corrected. The wheels of the train are designed with bearings to minimize friction. They come in two sizes: 10mm for the main wheels and 8mm for the side wheels.
