No on track, but the trixbrix on ebay digital printing are decent. I got their version of 7996, the color is spot on, its functionality is better as it has 4 switches rather than 2. I did put 2x1 flat gray lego bricks to secure the connection points. It does stay connected pretty well. For 50 bucks it is worth it.
Infact, their switch track curves out rather than in like the lego track. A decent alternative that isnt garbage.
