This is one set of the tracks. You can buy several different sets and create multiple track configurations. It is in original box. Very easy to assemble. I did it. Each piece is shaped like a puzzle and snaps together. It was only played with for a short period of time. My granddaughter was into cars. Didn’t last long she is into baby dolls now. This did not come with any cars. I am adding one to this listing. Everything is sold separately. It is for 1-5 years.
