Unfortunatelly the game don't remember the path patern you drew if you delete a queue or a ride. I hope they can improve it.
This is not a "undo" (ctrl+z) situation, because I placed a ride when I started the park and long after I had to remove it becaue no one was riding, and my path design under the ride was deleted also.
