Gröna lund said they would start building later this year (possibly winter bc winter wonderland isnt so likely to happen this year) sooo vekoma most likely are manufacturing the coaster and trains right now or they are waiting to show the trains or something
First: that train is NOT for gröna lunds coaster but for iron rattler. If you'd just looked at other options you would have noticed it pretty quickly. Second: I'm quite sure that the area for the Launch coaster and the family boomerang are NOT the same. Sorry, but I'll really have to say that you should have done more research before making such video
The train is already confirmed to be for Iron Rattler, the tilt at six flags qiddiya. it has a steampunk theme indeed, and the same track color as grona lunds coaster. however if you look under the train you will see no lsm stator sockets which the grona lund coaster does use.
