These Oldie Tracks Are Strange

I have seen those Plarail Advance tracks but I thought those wher made because the Advance trains are aren't easy to line up. Its also curious that in the first package the short pieces are both female where in the second package there is a male and female one.

There was already a 're-railer' type piece of straight track that you usually get with each Advance set, but its not so easy to line up two axles on four carriages even with this track. The idea of having the re-railer points that you just drive the train onto and it sorts itself out is quite inspired and to be applauded.
