I have had this packed away for aprox 25 years. My daughter and l used it and it worked great ,but that was a long time ago. I wanted to be sure all was still good so l laid out the track to be sure it was all in the box and yes it is. The back tires on both cars had cracked so l replaced with new ones. I plugged it in and it does work one car was not getting good traction,  possibly the track needs cleaning or with the new tires they need scuffing?.
