As I recall this was ~90' in lap length, in a 5'x12' s of space and easily expandable to a.much greater length. It is a pity I never mounted it on a table and added the elevations I had originally envisioned for the nested 180 degree turns,

I have to say it's amazing you fit that much (flat) track in that space. And I'm guessing the flow wasn't half bad either!

An excellent effort to get maximum track into a given space on the flat. The "folded dogbone" concept seems to particularly lend itself to this aim. I'm pretty sure there's a smaller variant on this theme in the Track Plans section, squeezing as much Scalextric geometry as possible into an 8x4, that I'm seriously contemplating adapting for routing, to make a compact but entertaining test track on a budget.
