I doubt it. It's been there at least 30 years.
There's another motive there that they don't publish. The local area has a reputation for attracting some groups of youth who often cause trouble. This has been seen to keep those elements out of the park.
One of the reasons for this is the low minimum height requirement to ride, which seems pretty random across the park. For example, my kid is 106cm. This means he is allowed to ride the Scenic Railway (with me), but is unable to ride Coney Drop (drop ride), the Twin Dragon (pirate ship), the Spider, the Dodgems, or the Sky Rider (Ferris Wheel). Really odd given he is able to ride the counterparts of at least the dodgems and the ferris wheel in other locations with me. I know it's about the restraints and all, but most parents just found it strange their little tackers were allowed on the big dawg roller-coaster but not the dodgem cars.
10m/s is the threshold apparently.
I don't recall ever having heard it run.
I dunno about that - it's pretty prominent. I'm not sure where you'd put it that's more prominent. The original location (which is where Pharoah's Curse is now) hidden behind the Disco Swing was the real afterthought.
I too visited the park a couple of days ago. The Scenic Railway was an easy highlight and worth visiting for on its own. Power Surge was a welcome addition, albeit one of limited re-ride value IMHO. Pharoah's Curse I've never been a real fan of - it's uncomfortable, slow, and short in duration. The Enterprise is still a great, smooth ride (although it never fails to surprise me how many people are frightened off by the thought that it goes upside down). The "Holodeck" (simulator) attraction is a bit embarrassing for the park, and they really ought to either do it properly or replace it. The screen inside it is very low-res (the video it plays can be seen on a monitor at the ops position outside the ride and is good quality) and is full of dead pixels. The ride motion itself is uncomfortable, shows little resemblance to the video and is very noisy. The audio quality also needs work.
One thing that struck me though was that with the exception of the Scenic Railway operations were incredibly slow. It seemed like ride operators were constantly coming and being replaced, and in the process of doing that it would mean all loading would stop for up to five minutes while the operators had a casual chat and a laugh about their plans for the remainder of the weekend. In other cases where two operators were allocated one would just hang out at the controls and the other would supervise unloading and loading solo.
The park could also do with some drinking fountains around the place.
