Why do you bother asking questions if you’re just going to ignore the answers? Space Mountain was completely gutted and it had to do with the on-board audio and “ride these rides to failure.” Steel does have a fatigue limit.So it's not an entire tear down/rebuild then? That's what I'm trying to figure out. Is very interesting to me because that is so rare.
There are several very high rated roller coasters 35, 45 years old and much older that haven't been completely torn down and rebuilt. Some that still hold world records.
None see the amount of riders like Disney does though. I'd love to hear from someone in Disney Imagineering on these issues with Space Mountain and what causes/caused them.. for purely geek purposes. Lol
