It was a complete kit with tracks included, but the company who made it is now out of business. All you needed to finish it was the radio and receiver. I did change out the electronic speed control for one that was better suited to the drive style I wanted. It is done for the most part, I am having some drive motor problems at the moment but I will get it fixed.
