That’s the crux of it though, it’s not an acceptable excuse from a customer point of view that they’re charging you to enter a park they won’t maintain.
People pay a premium at other places in the knowledge that unless advertised all rides will likely be operating, seems strange for parks of the calibre of Merlin’s not to do the same.
Complicated when first installed?
Air was a prototype 22 years ago, I would think whatever is included in that ride is now something that can be improved upon to increase reliability.
Nemesis has been replaced and seems more reliable than ever.
I agree to an extent. But I think the point that was being made is that we are where we are due to lack of maintenance budgets over many years and the fact that the ugly issue rears it's head quite bad at Alton Towers is because most of the rides are technologically complex. Above average, meaning lots more time needs to be spent checking over the rides for morning checks, general maintenance and breakdowns (even if they are more rare).
Air may be 20 years old, Smiler around 10, Thirteen a bit older, they have had improvements to them for sure. But that doesn't remove the fact that these are the type of rides with complex computer and control systems, multiple lifts, switch tracks and many trains with huge amounts of sensors, wiring and redundancys that can all go wrong and need checking on a regular basis. Much easier to check and troubleshoot a ride with 10 sensors than it is when the ride has 500, much more motors, greese points and whatever else. Regardless of how many reliablity increasing improvements have been installed.
Nemesis is reliable for many reasons, one being because it's very basic in terms of complex control, blocking and other systems. A relatively basic blocking system, two trains and one lift. Its basic in terms of modern rides. Much less to go wrong on a technical side than many other rides on the park.
When you have complex rides like Alton Towers do, you need a strong maintenance team which for whatever reason has dwindled. Other parks cope fine, for sure, they have the man power needed to service the complex rides.
