Marble Run - Space Rail (Level 5)
We were gifted this marble run (already built) but our kids weren't really interested so I have no idea if it's all there. It looks like it probably has a motor with a lift to bring the marbles back to the top. There's a bag of spare parts and instructions for putting it together. I'll keep it made up in case that makes it easier to check against the instructions. I tried a marble down it and some adjustments definitley need to be made, but I should think all that is possible.

Collection from Trowbridge (Green Lane area)
