(Østlandets Blad - paywall) Tusenfryd forbereder seg til tidenes attraksjonsinvestering Tusenfryd vil allerede neste år komme med en ny overraskelse, men direktøren i fornøyelsesparken gleder seg enda mer til 2021. – Det blir noe nytt neste sesong, men vi jobber med noe veldig stort for 2021...
I think it was also confirmed in an article in a local newspaper, but those are a hassle to dig up as they require paywall access. I had a friend from the area show me the articles once.
EDIT to mention: The name actually fits quite well, as TusenFryd used to have a small Zamperla Dragon coaster named Dragen. It was very popular, but apparently cost more to maintain than the park was willing to pay for, so it was sold. The public still has Dragen in fresh memory, so bringing back the name for a bigger coaster would be a neat publicity stunt.
As for the involvement of Gerstlauer, I can only confirm it personally. I know someone involved in the project.
Spoke to a friend who has been a seasonal worker there for many years. He has talked with the mechanic team at the park, and they seem pessimistic about getting it open next year. Still missing a lot of ground work, apparently, which needs to be done before Gerstlauer can move in. But the site has been fenced off, at least. I'll see if I can get permission to post his photos here.
The picture below is the same place, with the dirty panti- er, gloves not being as visible on the fence (they're still there but very hard to spot against the background - above the far right corner of the table).
The pictures were taken at some point in August, so they aren't day fresh, but still, it shows there was quite a bit left to do of the groundwork before any coaster crew can come moving in. It could theoretically be done before winter arrives, though. The ground won't freeze until November or so. But getting the coaster ready for opening day 2022 seems like a stretch. Maybe they'd get it open for mid-season, but I believe 2023 to be more plausible, given the time required to train ride ops and such. Besides, if they postpone the opening of this attraction, they can wait an additional year before opening the next attraction, and that will look good in the spreadsheets.
