I was thinking that it would be cool to have a projected rails directly above normal rails, but it seems like I cannot place them like that. They become diagonal, break when there are more than 2 placed, curve etc. Just weird behavior. Try for yourself to see what I mean.

• Here a screencast of how the carts snap weirldy
• Here how weird placing them is and that it's not intuitive

I also wonder, if maybe wouldn't it be better to have projected rails in the air have hitboxes?
