Gröna Lund: General Discussion

I thought it looked like more than just concept art! So that layout is fairly accurate to what they'll be delivering.
 
Absolutely gutted - loved Jetline, but an understandable decision really. Given the nature of the support structure, I suspect some of it might be retained anyway. It'll be interesting to see how that unfolds.
 
A summary of what happened for those who do not wish to read the full report:
  • A "support arm" at the front of the first car, to which the wheels are attached, failed and collapsed
  • This support arm was added to the train in Spring 2023 to replace the original that had worn out
  • The replacement support arm was incorrectly manufactured; it did not have a required cross plate and there were serious welding defects
  • The park used a Swedish company that they have used many times in the past for these new parts, but the work was outsourced to a subcontractor; the park were not aware of this
  • The person doing the welding had no formal welding training or a valid welder's examination certificate
  • The original drawings used to make the new parts were not clear as to whether the cross plate was required. Grona Lund experts thought that the drawings were clear
  • Due to the failure and the sudden stop of the train, the lap restraints were subject to 5 times more forced than they would be during an e-stop; the brackets of the safety bars became curved (and I assume some failed)
It's all pretty damning, a huge mess up from the various parties involved. And possibly shows the risks involved when having to get parts for rides where the original manufacturer no longer exists, especially when there is limited communication between the various parties.

A shame that Jetline is being removed, but not surprising.
 
What's worrying is that faulty part, even if it was made by someone who wasn't qualified, must have passed through multiple inspections from people that did know what it should look like. At the very least I'd have expect the mechanic who assessed the train daily to have noticed dodgy welds and missing sections.

With so few of the classic Schwarzkopf's left it is such a shame to know this one could have still been going strong had they not botched what should have been a simple part replacement.
