It's also worth nothing that TRR was in line for a massive overhaul a couple of months after the accident actually occurred. No where near enough to bring it to even an acceptable standard though. If the proposal was followed in full, there would have been multiple extra, HD monitors added to the op booth and a complete teardown and rebuild of the PLC's. Surprisingly no upgrades were planned for the conveyor, so even if the full upgrade went ahead, the slats could have still been the cause of a disaster. Less likely though as spacing would occur from the moment you enter the lift hill and be entirely computer controlled. Much like how Snowy River Rampage at Wonderland was designed.
Not known: How many e-stops were planned to exist after the upgrade.
TOT, oh boy, they tried so hard to revive that thing but it was a battle they weren't going to win. Making the decision to blow through the last of the spare parts to give it a good send off was definitely worth it. Even if the full upgrade was done when the car got flipped, it would have still only had a few more years left in it. SFMM is super lucky that they were able to cannibalise TOT for parts because theirs on its very last legs too. Estimates are that it's only got a couple more years left in it, at best, thanks to the parts.
Wipeout was like TOT. A retired legacy product that the manufacturer no longer supports. Even less so than TOT because Intamin were a lot more keen to try and keep the final two towers running. Vekoma weren't as keen to keep the second last Waikiki Super Flip running. The only other one existed in Mexico and closed down about a year after Wipeout did. Most likely due to the more relaxed regulations in Mexico compared to Australia. Some of the parts of wipeout were so beyond repair that they were about 70% welding material. The reason they were able to run it for so long before finally pulling the trigger was because before all hell broke loose, they had ordered parts to be custom made. Those couple custom pieces are why it was able to limp around in its final months. Same with why it was such a challenge to park and operate in its final days. All the parts were cooked and they had to be delicate and careful to not just implode what was left and kill the ride even earlier than planned.
Log ride was a matter of time because the concrete troughs have some damage but it's also a solid, traditional ride with minimal moving parts. The troughs were damaged further during deconstruction of the cave areas and the logs were getting torn apart by the cages. So if TRR didn't happen, I'd say this ride would have stuck around for many, many more years. If TRR didn't happen and management never changed. TOT and Wipeout would have been SBNO within a few years anyway.
