Still looks better than Smiler's station...
Hansa Park said:KÄRNAN’s total track length will be 1,235 metres.
KÄRNAN’s first drop will be a 67-metre plunge.
KÄRNAN will require about 200 supports outside the buildings.
KÄRNAN will also be a terrain coaster running just slightly above the ground on certain ride sections.
I can only speculate from this, that it will be a vertical lift and drop inside the tower, possibly enclosed entirely, which fits Gerst drop styles, and explains the enormous width of the Tower as well.
