space-age monorails/track sets/etc.?
I've been wracking my brain for a few hours now, trying to remember who made a certain toy, what it was called, or anything else about it -- all to no avail.
Here's what I do know: it was made in the '70s, it was "futuristic"/"space-age" looking, it had interlocking plastic tracks that were not only straight but up and down, making it a sort of 3-D train set, with a touch of rollercoaster. It had streamlined white vehicles that grasped the back side of the track with gears, allowing it to slowly, noisily climb. It was both rad and *****in' (those were the '70s). I think it was made by one of the major Japanese manufacturers.
If anyone can remember what this is, I'd love to know. And beyond that, can any of you help me add to my "database" of space-age toy track/guideway sets (NOT slot cars, Hot Wheels/Sizzlers, railroad trains, etc.) of the '50s through '70s? Here's what I've got so far:
the aforementioned mystery toy
Mego Micronauts Microrail
Mego Rocket Railway
Mego Micronauts Rocket Tubes
Schuco Disneyland-Alweg monorail
