I got a nice deal on alot of older blue track

I didn't know they made the road track with the same connector as the trains.

They didn't. I suspect there's a slight misunderstanding in one of the comments above. The blue 'T' junction pieces with white flappy-bits are of course road pieces, and the smooth blue 'auto-double-crossover' - you've shown a number of pictures of it - is rail.

One set that both came in was the "Tomica World Super Deluxe Set" 7423, which also had the wide-radius curves. Looking at your pictures I'd say there's a strong chance that this is the track you bought. Maybe it's not complete, but the bonus super-bundle of gender changers more than compensates.

This video shows both pieces in action:
