Hello Gary,

Speaking of creative AFX tracks.

Now you see it.

   

Now you don't.

   

A 2x4 was securely attached to the wall. Then 4-hinges were added to a 3-foot by 7-foot plywood board. The track is screwed down to the plywood. Two hinged supports fold down by gravity. The wiring runs under the track to each end. With children of any age, cars are likely to fly off the track. The design of the track is somewhat self marshalling by each racer.

   

You might be able to come up with a similar idea for your set. Another idea is hanging it from the ceiling, and hoisting it up when not in use.

I look forward to seeing whatever you come up with.
