That’s the first time I’ve actually seen Zierer get the manufacturing credit. The 4 companies were so intertwined though that it’s not at all shocking and there’s no doubt it’s basically the same as all the other Schwarzkopf coasters (excluding layout obviously). I once took a deep dive into the history and my mind exploded. The Wave Swinger ride is where things got really wild. I can’t remember all the intricacies but Zierer was mostly close with Anton’s brother (hence why the swings are Zierer rides) but the cooperation between those 4 companies really blurred the lines of who did what… Kind of reminds me of PTC and how the line between wooden coasters pre-2000 is so blurry.

I honestly miss the collaboration era. We have companies today doing some insane rides but could you imagine if Intamin and Gravity Group worried together on a new pre-fab woodie… Or B&M and S&S?

As for Grona Land, from everything I hear about it it seems the popular opinion agrees with you… The accident in Mexico was written off because that park was known for not doing maintenance so hopefully this causes people to take notice – not that the rides need removed but that there is something with these wheel bogie connection points that needs some serious review.
