This is WiFi controlled N scale train. It uses my own highly efficient wifi controlled DC motor controller https://github.com/andrejcampa/WiFi-motor-controller.

Additionally, this train hull fits Tomytec TM-07R Motorized Chassis. It is quite easy to print.

More detailed instructions on how to build/assemble the complete project can be found on the GitHub page. https://github.com/andrejcampa/WiFi-motor-controller

You do not need to use the Wi-Fi motor controller module to have a functional train.
