I wonder if this is Cartronic track, which makes track (it appears to me) which looks exactly like Carrera track, but which has different track connections (which look like they go together much easier than regular Carrera track). I have been looking to pick up some of their track (I haven't found a source in North America), to see if I could modify to match to my Carrera tracks, to have locations in my layouts which snap together easily (I love my Carrera tracks, but when you are trying to put together 6-lane high-banked tracks, with the offset crossovers I use (which means I have to line up all 12 tabs for the six lanes to slide together at one time, which is even harder when it is elevated, and when you have to "stretch" the layout for more challenging configurations), it can cause you to lose all your humanity). Check to see if it is Cartronic track, maybe even private labeled, or some other track that is still compatible with Carrera lane spacing. Can you tell us where to find the track sets you saw?
