I have built the track up, the cars seems to spin the wheels but don't move, iam not sure if this is just a case of it needing a good clean? They're are some spare tyres and contacts which may fix the problem. This has been in a loft for over 30 years. Iam not sure if this has extra track as it dosent seem to fit in the box very well. I have added a video of what happens when I press the controller.
